I guess I'll run through my setup and and my issue. So my speakers are Monitor Audio RS8's, RSLCR, and RS1's, my sub is an Axiom EP600 my amp is an Emotiva XPA-5, and I have a Yamaha receiver are my pre-amp(waiting on XMC-1). Typcially I use my setup for TV, movies, and gaming. However, sometimes (when I'm cleaning house, paying bills, or whatever) I like to crank up some music.

I typically listen to rock, punk, metal and I always feel like it's missing some bass. The highs sound great, the low-lows are fine, but when someone is really grinding on the guitar I should feel it more. My computer and car speakers seem to do fine in this area, but I cannot seem to use an EQ to get the sound I want. Despite my speakers having similar or larger drivers. I've looked at the mid-bass module by HSU, but it works off LFE out and my LFE outs do not carry signals below 100hz (maybe even 80, can't remember at the moment).

Any suggestions?

This may be not help, but I run an additional sub (8") between my cc output and cc speaker set to large and find I get additional mid bass control. It's because I am cheap and probably don't pay as much attention as I should to main/sub/room compatibility and find it cheaper to add a "mid" sub. I like my additional control of vocals without adding the 100 hz boom to my main sub. set at 60 hz. Try it, you may like it. The power handling of the cc is improved as well. Try other settings like "stereo only" etc. to isolate speaker deficiency.

LFE is only for movies AFAIK, not music.

You might look into putting sub(s) nearby the mains, and using shelving filters to boost the midbass area you want. The reason for putting them close to mains is for localization issues. There are those who use stereo subs with a DCX2496, but they might also warn you of increased panel resonance of shoddy subs with the higher xovers. There's also the possibility of sitting in a LP where nulls are bad. YMMV.

LFE is only for movies AFAIK, not music.Huh? If his speakers are set to SMALL, the rerouted bass is sent to his subwoofer out. (Yes, he incorrectly called it the "LFE out".) Apparently his receiver has a fixed crossover.



Ryan W, do you realize that, unless Axiom has "corrected" it, unlike most any other subwoofer, your subwoofer has a VERY steep low-pass filter at 100Hz (iirc)? Even if you set it to "bypass". This may well be the source your problems. An MBM would help. Your receiver's fixed crossover point is not an issue at all. The MBM has a high-pass filter at 50Hz and it covers the frequencies between 50Hz and your receiver's crossover. Your 600's low-pass would be adjusted to the 50Hz filter of the MBM.

A small sub for your front channels, even when they are set to SMALL, would help you boost the frequencies around your crossover point. Of course, you could get a sub for your front channels and run the front channels as LARGE, and not rely on the subwoofer for your music.

Huh? If his speakers are set to SMALL, the rerouted bass is sent to his subwoofer out. (Yes, he incorrectly called it the "LFE out".) Apparently his receiver has a fixed crossover.

The only reason I stated "AFAIK" is because I've never once got to enjoy a mch listening session, outside of Bluray. I do not have a clue how things are designated on SACD or DVDA or DTS music discs. Huh? Were you correcting me, or were you not correcting me?

That's interesting about the Axiom subs.

That's interesting about the Axiom subs.Would you hold it against me if I was correcting you? ;)

It wasn't clear to me that he was referring solely to MCH music. But if he was, and he is decoding at his receiver, it will apply the same bass management it would otherwise apply to movies (and 2-channel music, for that matter). There are issues with some universal players not being able to apply bass management correctly to DVD-A, and instead, defaulting the channels to LARGE, but I am pretty certain this is not what he is describing (see below).

I suspect, though, that if he set his front channels to LARGE, he would get better bass performance with music as I suspect his issue may have something to do with his sub's steep filter at 100Hz. Although, the complaint about weak midbass is common with owners of other monster subs, too. So, it may not have anything to do with that.

Wouldn't he also get this by having his speakers set to SMALL and having the crossover set to 80Hz?

Huh Huh HUh HUhUHUHUHUHUHUHUH??????

Wouldn't he also get this by having his speakers set to SMALL and having the crossover set to 80Hz?I assume from his post that his speakers are already set to SMALL. And based upon the post, I think that his receiver has a fixed crossover point. If it is at 100Hz, then his subwoofer's steep 100Hz low-pass filter is going to cause it to drop even more steeply at 100Hz, so his sub is not going to be reproducing the small bit of frequencies above 100Hz that it otherwise would be as dictated by the receiver's crossover's LPF slope. Even if his crossover point is 80Hz, the sub's filter may be his issue, but it might be less likely. Or, his problem may not have anything to do at all with his sub's steep low-pass filter. Even if he had another monster sub from another manufacturer, he might have the same complaint; that he is lacking in the mid-bass department. It is a common complaint with subs that are tuned so low. They can often lack punch in the upper range.

..............my LFE outs do not carry signals below 100hz (maybe even 80, can't remember at the moment).OK, Ryan W, in reading your post again, this doesn't make any sense at all. Did you mean to say your subwoofer out doesn't carry signals ABOVE 100Hz? I thought you were implying a fixed crossover at 100Hz (or, as you say, maybe 80Hz).

Clarification?

Maybe he simply has to add some distance to his subwoofer distance control to get the speakers in phase with the subwoofer!

Maybe he simply has to add some distance to his subwoofer distance control to get the speakers in phase with the subwoofer!Yeah, it could be a phase issue. Could be anything, I guess. Still waiting for the OP to post back.

As you said, most all low tuned subwoofers seem to be lacking in the mid bass. I would not use that subwoofer for anything much above 50 Hz. Kind of hard to set the LFE HP in the receiver to 120 Hz when the sub is HP filtered at 100 Hz in the subwoofer amplifier. That filter looks to be a very steep 8th order 100 Hz filter.

That filter looks to be a very steep 8th order 100 Hz filter.Yeah, it is super steep. And a known "issue". I don't know why they designed it that way. If you look at the back of the amp, the low-pass can be adjusted up to 100Hz and there is even an all but useless bypass setting.

http://www.axiomaudio.com/global/images/products/gallery/amp.jpg

Ok some clarification. Yes I meant above 100hz, the crossover is set to bypass, I am using the receiver (Yammy 663) to control the subwoofer (sorry not LFE) output. The front are set to large, they're RS8s and I like to take advantage of their bass drivers. Phase and positioning definately could be a factor, but even listening to these speakers without the sub on, the issue is there. You guys are right on with the Axiom, it's not going to matter what I set my crossover on the receiver to because the sub won't push anything above 100hz. So theoretically I guess adding the MBM to the second sub output could add what I am looking for. Anyone have any opinions on it?

So you're using the high level input on the amp? Does that mean the fronts are receiving the full bandwidth? I've seen some subwoofers that had a highpass output to the mains if using the high level input is why I ask.

If both the sub and fronts are playing the same signal (below 100hz) you can easily get interractions which can cause cancellation, meaning you're losing bass, even midbass. Have either the sub play it, or the mains, but not both. Maybe set your receiver's crossover at 80hz (speakers on small) and use the RCA sub output to the subwoofer.

After you've played around with different settings and speaker/subwoofer positions and are still not happy, then look into some type of midwoofer. As previously pointed out, phasing is an important aspect that might be overlooked.

No I'm not using the high level input. Yes, right now the mains are getting full bandwidth and the sub is also on. However, I've tried it both ways and I prefer having it this way. I've been playing around with it for quite some time. The one area where I have tried very little in terms of change is sub location. I don't have many other places I can put it. I've tried adjusting the position/direction in the area where I can keep it, but haven't seen much change. I could benefit from buying a decent mic and running REW, but I do not have an SPL meter I can hook up to my PC to run it. It's something I need to invest in and maybe I should go for that before the MBM. However, I've played with various settings, done one complete rearrange of the room, and found what I consider to be the optimal sound from what I have available.

After reading that back to myself I wanted to say that's what she said like 5 times, but anyway...

I think that I could benefit from the MBM though. The EP-600 isnt the best at reproducing bass at 60hz+ anyway IMO. Being ported and trying to reproduce 20-100hz it can get muddy sometimes. It's always sounded better to be that way.

Try setting the speakers to small with a 60Hz crossover on the receiver and bypass on the sub. Then try it with an 80Hz crossover. You may be surprised by what you hear. Also, do you know what notes the guitar is playing when you feel it is not up to snuff?

My guestimate is that there are 2 problems here. First, when set to large, the RS8s are interfering with the bass output of the sub and lowering the perceived volume. Second, the internal crossover from the dual 6" woofers to a single 6" mid is probably somewhere in the guitar's range (100 - 1000 Hz), so when you say you feel like you're missing something, you could be hearing this transition.

Ryan W, with your speakers set to LARGE, the sub is not going to have any output with 2-channel music (I presume you know this). So, I assume your complaint is in regards to multichannel use. What sources are you unhappy with? With true multichannel sources (DVD movies and specifically recorded multichannel music), the only output you are going to get from the sub will be the LFE channel (if there is one) plus rerouted bass from those speakers set to SMALL. And when applying a multichannel DSP to 2-channel material, the only output from the sub will be rerouted bass from the already matrixed SMALL channels.

What sort of music listening are you doing that you are unhappy with? 2-channel? Matrixed multichannel? True multichannel?


The front are set to large, they're RS8s and I like to take advantage of their bass drivers.I am surprised that with the speakers set to LARGE, you are not getting enough midbass. As you say, that should take advantage of the larger drivers. So, how does 2-channel-only music sound?

If you definitely want to run the front speakers as LARGE, you may want to experiment with an LFE+Main, LFE Plus, Both, (or whatever your particular receiver calls it) setting. However, as others have pointed out, the bass redundancy that this setting produces can result in some interference that can actually result in less bass.

When you have tried setting the fronts to SMALL, what crossover did you use? You could probably benefit from an MBM, but you would need to run your speakers as SMALL. Your 600 would then only be responsible for 50HZ and down. The MBM would cover everything from 50Hz up to your receiver's crossover setting. You'd be able to individually control the volume of each sub to your liking (but, technically, you should try to achieve a flat FR). Since you say you have another subwoofer output, sure, you would probably want to use it. But a Y-adapter will work, too, and may be preferable in terms of your cable management.

What would be an example of a MBM?

Would it accept the sub out from the receiver and perform a cross over at 50Hz and have a sub-out?

You connect it to your receiver's sub out along with the main sub; usually with a Y-adapter. Then you adjust the main sub's own low-pass filter to the MBM's 50Hz roll-off (will be somewhere in the neighborhood of 50Hz).

Does anybody else have mid-base subs that are great in the 50-100 Hz range (I notice HSU says this is a patent pending process, so maybe not)?

I would have thought that a really nice 8" or 10" driver could do well in this range.

The Yahama allows be to set any speaker to large and LFE output to both. I am pretty positive I have bass output from both on 2 channel material. I know for a fact the fronts are set to large and that during two channel music the sub works. So I assume this is what your second paragraph is about?

I listen to a variety of sources, but the music where I feel I notice it most is hard rock, metal, punk, even some acoustic rock seems like it's not carrying over that reverberation you would feel from a guitar. Now I often just put on two channel music and listen to it while I'm around the house. I also play alot of rock band/guitar hero which I listen to multichannel. Now that's not true multi channel audio I guess, but none the less I notice it there too. I have a few multichannel SACDs, but honestly I haven't listened to them in a while and they are generally not of the music type where I notice it (except maybe Dark Side of the Moon).

But unless I'm mistaken, which I very well could be, the BOTH option allows me to utilize the mains and the subs for bass. So I could add the MBM, to supliment the 50-120hz region. Granted, I may want to set my fronts to small at that point to ease bass management. At the very least I know that the RS8's do roll off after 80hz or so, based on anechoic readings. This may not translate to the same frequnecy response in my room though. However, I could change them to 120hz+ change the EP600 to 60hz and below and cover the middle with the MBM providing me more punch in that area in the process most likely. Correct?

My Sony receiver also has the lows going to my sub when the fronts are set to large. When my speakers are set to large the fronts receive more bass when I option "no" sub as opposed to when I set it to "yes". It took me awhile to learn I get different crossover settings on my receiver depending on a few options I set. I imagine a good receiver has totally adjustable crossovers which would take the guess work out of it.

Yes, Yamaha's "Both" is equal to "LFE+Mains." A simple test to do without a SPL meter is to download some tones from 60 Hz to 200 Hz and play them through the system. While playing, walk around the room, particularly near walls and corners, but center areas as well, and sit in the listening position- are there large volume changes? This will indicate peaks/nulls. At a position where you tend to get peaks, listen to music and see if you get the response you're looking for. If yes, then you need to control your peaks/nulls- it's very possible you're getting interaction between the sub and mains.

It could also just be his room, or the listening position in the room. Then again, he could be expecting to get more out of his recordings than is recorded on them!

Does anybody else have mid-base subs that are great in the 50-100 Hz range (I notice HSU says this is a patent pending process, so maybe not)?

I would have thought that a really nice 8" or 10" driver could do well in this range.Not really specifically marketed as such. Not that I know of anyway. You can't just do it with any sub. You have to be able to high-pass the sub you use for the midbass. You could "build" your own with some inline filters (see "F-mods").

The Yahama allows be to set any speaker to large and LFE output to both. I am pretty positive I have bass output from both on 2 channel material. I know for a fact the fronts are set to large and that during two channel music the sub works. So I assume this is what your second paragraph is about?So, it seems you are already using the "Both" setting. Why, exactly?

Set it to LFE only and see what sort of performance your front speakers provide you on their own with 2-channel music. Still lacking mid-bass?


But unless I'm mistaken, which I very well could be, the BOTH option allows me to utilize the mains and the subs for bass. So I could add the MBM, to supliment the 50-120hz region.Right, with the BOTH setting you would get more out of the MBM if your fronts are set to LARGE. But (and think about this for a second) the same exact thing is sent to the sub(s) when your speakers are set to SMALL as is sent to the sub(s) when the fronts are set to LARGE with the BOTH setting. The only real difference is what is being sent to the fronts. I suspect that with an MBM you wouldn't feel the need to run the fronts as LARGE.



Granted, I may want to set my fronts to small at that point to ease bass management.Right.



At the very least I know that the RS8's do roll off after 80hz or so, based on anechoic readings.The Monitor website says those speakers' FR is 33Hz - 40kHz. They should probably be run as SMALL, although I think you indicated your receiver has a fixed crossover. Is it @ 120Hz? What receiver is it?

And, again, I am surprised that with those speakers and subwoofer and using the LARGE and BOTH setting that you do not get ample midbass for your tastes.


However, I could change them to 120hz+ change the EP600 to 60hz and below and cover the middle with the MBM providing me more punch in that area in the process most likely. Correct?Correct. Is 120Hz your receiver's fixed crossover point? You'd set the 600's crossover wherever it blends best with the MBM's 50Hz high-pass gilter. I can't tell from the picture whether it is continuously variable or not. It looks like it might only click at 40, 60, 80, and 100Hz.

It could also just be his room, or the listening position in the room.Yep.

I am interested to hear what he thinks of his speakers operating with 2-channel material on their own.

I've spent some more time playing with it today. I really need to borrow my buddy's SPL meter again and take a look at it. I think alot may just be the room. I changed the fronts to small, tweaked the EQ a bit, I set the crossover to 80hz. This seems to be working a little better. Still, I popped on some Coheed and Camrbia and some Pantera and I really think right in that midbass is where I'm missing. For instance the violins in Welcome Home just didn't have that richness I'm looking for, but the guitar solo on Gravediggers and Gunslingers sounds great. Cowboys from Hell main riff also felt a little light, but the vocals are good. I could play around with plugging up the ports again, they have front and rear. Last time I didn't like the impact of it, but it's worth revisiting.

Do you think your receiver might have anything to do with it? I auditioned receivers recently and discovered that, while playing the same music through the same speakers, there was a significant difference in the midrange between receivers. I found that while the Yamaha's sounded good, and Denon's sounded more full, the Marantz's opened up the music considerably. Before you consider adding the MBM, if you can, try a different receiver and see if that might give the impact you're looking for.

I run my system with a Yamaha and am extremely familiar with the sound. I was pretty skeptical about receivers sounding different until I went and listened for my self. There really was a difference between them. So much so, that I am now saving to upgrade to Marantz!

Does anybody else have mid-base subs that are great in the 50-100 Hz range (I notice HSU says this is a patent pending process, so maybe not)?

I would have thought that a really nice 8" or 10" driver could do well in this range.

For a commercial product, HSU is the only company I can think of. I still, however, don't understand why we have it. Bigger, more competent mains are what's needed.

8-10" could work above 100hz at high output, but they won't work too well even a half octave below that. Ideally, I think people should use 15's (which is what I'm upgrading to) for their woofers, which will give all the midbass output you'll need. Thus meaning you won't need some MBM. However, people want these small, skinny, posh looking speakers and what they get in return is a lackluster sound.

So what's worse, complaining about your sound or thinking that your speakers look too big...but play so loud you can't hear yourself think anyway?:D

For a commercial product, HSU is the only company I can think of. I still, however, don't understand why we have it. Bigger, more competent mains are what's needed.HSU summarizes it pretty well on their website:

"Just like the VTF concept, a woofer optimized for low bass reproduction is not the best for mid to upper bass reproduction. A heavy cone is best for low bass, but that reduces the mid to upper bass efficiency. The MBM-12 woofer is optimized for mid to upper bass reproduction - a very light cone, low inductance voice coil, and a strong magnet yields extremely quick response with high efficiency. It demonstrates excellent micro-dynamics and an extremely wide dynamic range that no single subwoofer can provide."

So what's worse, complaining about your sound or thinking that your speakers look too big...but play so loud you can't hear yourself think anyway?:DSo, are you implying that one should use LARGE speaker and the LARGE speaker setting? Or simply a much lower crossover setting? And a 15" woofer may be fine if the speaker is a 3-way (or more) But if not, midrange performance will probably be seriously compromised, especially if run as LARGE or with a lower crossover setting.

"Small, skinny, posh looking(?)" speakers do have several advantages. Aesthetics aside, they often image better and can provide better midrange performance (among several other things). They can also often provide more performance per $$$$. And the benefits gained at the amplifier level by running speakers as SMALL are not there if they are run as LARGE or diminished if run with a lower crossover. With older receivers, the LFE channel is often truncated at the crossover point, so running a lower crossover will only truncate the LFE channel more than a higher one would. There can also be issues with running a lower crossover point if one's surround a speakers are considerably smaller than their front speakers and they only have the capability of setting a single global crossover setting.

What 15" woofer-equipped speakers are you upgrading to, Looneybomber?

He is used to boomy bass.

HSU summarizes it pretty well on their website:
That product is a band-aid product because an MTM with 6.5" woofers can't keep up with today's powerful subs. So instead, do what used to be done. Build large 3ways using a 12 or 15" woofer. Now you have the same thing as a normal 2-way speaker with an MBM.


So, are you implying that one should use LARGE speaker and the LARGE speaker setting? Or simply a much lower crossover setting? And a 15" woofer may be fine if the speaker is a 3-way (or more) But if not, midrange performance will probably be seriously compromised, especially if run as LARGE or with a lower crossover setting. Run them large or small, that's up to you. But yes, a 3way would be a must. Maybe even a quasi 3.5way like what i'll be doing (MTMW)


"Small, skinny, posh looking(?)" speakers do have several advantages. Aesthetics aside, they often image better and can provide better midrange performance (among several other things).?
Imaging is a non-issue if designed properly. And better midrange performance out of a small 2way tower speaker?

What 15" woofer-equipped speakers are you upgrading to, Looneybomber?[/QUOTE]
Similar MTMW design as this, but with...well all different drivers including the 15" version of that woofer instead of the 12" as shown

For the past 2 days I have been listening to Direct Mode on a Denon 3808ci and Aperion 6Ts. I run LFE + Mains and have them crossed over @ 40. Also have a SV PB 13Ultra and it sounds like the artist are in the house-excellent highs mids lows. Streaming from my computer through the Denon. Do you have Direct Mode selected, with LFE+Mains, or the equivelant on your receiver? Change x-overs and experiment.

I'm sure they sound great, but those speakers are impractical for most people, Looneybomber, especially in a HT setup. And I would consider those to be "bass bins". Sure, I'd prefer speakers that didn't even require a subwoofer. But that's not reasonable for me or most people.

with just lfe some music does not have a signal-lfe+mains the sub is working.if you change the mode to "direct" or "pure direct", or if you set the mains to large, then you will not get any bass from the SW when set to "LFE"

LFE+mains simply sends the bass signal to both the sub and the mains (even when it is set to large). the only bass that gets sent to the sub are the frequencies below your the crossover poitn set for your mains.

LFE+mains simply sends the bass signal to both the sub and the mains (even when it is set to large). the only bass that gets sent to the sub are the frequencies below your the crossover poitn set for your mains.
_________________________I know all that.

Do you know the difference between LFE+Main in "Stereo" mode versus "Direct Mode"?

Yeah- I started out in direct mode and small, which is bypassing tone controls but I wanted to hear some bass out of the sub...so basically in this setup stereo is the same as direct. No diffrence

Those speakers scare me for some reason. :eek:
