I find this VERY surprising. In my room, the difference is very audible.

Great....now I want to get a good pair of headphones.

There are the specs and then there is what we hear... I try and never confuse the two as they can be at odds sometimes and in that case my ears will always win out every, single time. One possibility could be that your room is somewhat 'loose' and so that makes it much less noticeable, in which case go with whatever your senses are telling you is more pleasing to your ears for the source material... I believe that's why Brian gave us those settings choices to begin with.

Try whatever earbuds you have lying around. I use a $50 pair of Grado cans. It need not be fancy, just gives you an idea of what your source sounds like minus your room.

Well I finally bit the bullet and went for my first subwoofer purchase. Due to WAF issues I had to spend extra and go for the E15SE.

The only thing I noticed is a slight reduced in sound level when I flipped the switch while the music/sound is playing.

Perhaps a few variables...
1. The room is not ideal to begin with. The room size is roughly about 4500 cubic foot...then it has opening to kitchen, and opening to hallway to other rooms.

2. I don't have high quality recording source + bad equipment setups. Tell you the truth, for stereo music, the Bose system in my car sounds 1000x better than Focal+Rythmik(or Focal Sub)+Denon AVR ...this is to show how bad my setup is for stereo. The Eagles: Hell Freezes Over CD [not the DTS DVD version] sounds great in car, but sounds crappy in house.

3. Maybe (grasping straw for air here) due to opposed drivers configuration?

4. I don't think rerun Audyssey does any good since the amp is controlling at this point.

I meant, why did you choose it as a starting point, knowing that you have a bad room to begin with.

Not a knock or an attack, just trying to understand the logic.

Not to fret... my basement theater was really bad for acoustics for many, many years but I worked on it and over the years did much to improve that space... that really is the hobby of audio, getting the most out of what you have. Many, MANY people I know who have reasonably good equipment say the same thing as you, that the system in their car sounds better... this is not unusual at all. Up until about 5 years ago I was saying the very same thing. You got really good stuff, its just the environment you need to work on at this point. If I might make a suggestion, I would say start by getting an SPL meter and download the free REW (there is an excellent tutorial that goes with it and you can find forum help over here as well as at the 'Shack'). There is real power in knowing what you are up against acoustically speaking and being able to visualize what you are hearing is the best tool to help you decide on a plan of attack to improve the space you're stuck with. Once you can see the frequency response at the listening positions, you can far more easily evaluate sub (and even speaker) placements to optimize response with respect to listening position(s)... bottomline is you're really just looking to remove all major nulls in the bass region as Audyssey will effectively EQ out the peaks for you and together that should give you are reasonably flat(ter) response. Next you can analyze the graphs for reverberation times and begin to do things to reduce it... often room treatments will be necessary, yes, some will be bulky but it need not be ugly. There are many tasteful designs available and you can even DIY if you so choose. By the time you get that far it will most definitely sound better than your car. However it all begins with being able to analyze your room's acoustics... lousy equipment will always sound lousy, but even the best equipment can still sound lousy in a "bad" room set-up, however the difference is with good equipment, as the room improves so too will what you hear coming from it. If you decide to do it and you find you need pointers to help you along the way, I'm here for you buddy... I have my own experiences to offer you as my knowledge-base and I've been through some tough challenges of my own in the last 10 years with my basement theater.

Congrats!!! Set it up right, get it calibrated in and do some critical listening... then post back here with your impressions. I think you (and the wife) will be pleasantly surprised...

That's such a rhetorical question, no? Everyone, including me...you, purchased subwoofer(s) to do one thing and only thing...BASS...room shapes or room acoustics are not included in subwoofer(s) buying decision. That's the starting point. Without loudspeaker(s) and/or subwoofer(s), we don't have bad accoustic room, right?

Unless, you have the impression that I am disappointed with Rythmik subwoofers? By all means, I am smiling ear-to-ear.

Thanks for the encouragements. I have the RS digital spl meter, but I cannot make use of it anyways. I do not have the space to rearrange subs/speakers location. The living room space is shared with office desk, huge cadillac escalade replica, and two huge sofas. This is condo by the way...placing sub against shared wall is a no-no especialling a dual 15 incher. The subwoofers purchase is a forward thinking...

General question.

What subwoofer cable are you guys using?

I'm thinking of getting some Kimber Kable Cadence or Analysis Plus Sub Oval.
Worth to shell out the dough?

Quad shield RG6 with proper connections, don't waste $ on those expensive cables.

Hi badgerpilot - mind sharing with us what the two subs are that you'll be comparing? One looks like a Rythmik D15 and is the other an Epik Empire?!?

If it is in fact the Empire then I would be very interested in hearing your thoughts on how these two handle music . . .!


Thanks in advance,
kevin

The smaller sub is not an Empire. It looks like an HSU.

badgerpilot is interested in the comparisons I will be doing, since I posted the photos.

That is a SVS PB10 on the left of the photo, it is deeper than the photo shows due to the fireplace, and of course the other is a Rythmik D15SE that Brian sent my way.

I just got a pair of Rythmik F15's / 370 amp in my 21' x 20' room with vaulted ceilings and dining room entrance. I decided on the pair to try to balance the square room, as I have a 10-12 db dip around 64 Hz, no matter where I place them. I went from corner to corner, only to reduce or increase it. My best location seems to be just inside the B&W 703 mains. They are about 8' apart, centered on that wall, and actually fit well.
I went with the Rythmik sealed boxes, because I enjoy music and reviews were great. I wasn't disappointed. I replaced an old MK V125 that did well for music, but sucked for HT. Placed in the corner, it had surprising output above 30Hz, but I didn't know what I was missing. The pair of F15's does very well for HT, with good output and headroom. I was afraid that I might need the 600 watt amp, but the 370 is fine and fit into my budget. HT is good and music is so much better. After months of reading other's opinions and agonizing over the decision, I believe I made a good choice.

Have you tried midpoints of opposite walls (either front/back or left/right)?

Not yet. This will involve moving heavy furniture, but may be possible. It's worth trying.

This is currently for a 2 channel setup and I am actively searching for a HTR. The settings that I have ended up using (all by ear) are the low pass filter at 50hz/24, Extension filter freq. 14 with hi damping with the delay phase at approx. 45 degrees and crossed over at 50 hz. I have not touched the peq at all yet.
I don't know if this will be the final settings but I am very pleased with the results so far. The sub has really filled out the bottom end of my speakers very nicely for music with a nice deep tight bass. The piano black cabinet looks awesome and the sub looks better with the grill off (wife disagrees so the grill says on

@ducky6: How about posting a few pics of your E15SE... front, back, grille on/off, etc. Other than a couple of photos of a black oak prototype which Brian posted earlier in this thread, I've not seen any of the finished product (certainly not on the website, Brian ).

TIA!

This is for garymb........These are the only photo's I have right now. I can take a few more next weekend but as you can see I am not a very good photographer. The photo's of the sub in piano black has a lot of reflections of the surrounding wood.
On page 7 post#208 there is a photo of a F12se which is a better example of what the sub would look like in piano black.
