I think. I don't have a proper sub yet. I still can't decide between a Rythmik or an SVS. Problem is, I just can't find any Rythmik's in the UK. Plus my Z5500 kicks out so much bass I can't imagine how these proper HT subs would be.
Bass info from any channel (not just the LFE channel) can be redirected to the subwoofer with proper bass management in the AVR.

So maybe the best thing to do would be to use LFE + Bass Redirection? Then the subwoofer should get signals from both the LFE track and the rest of the audio tracks? Best of both worlds kinda thing?...

The Line In uses the Front Left and Front Right audio channels to supply data to the subwoofer, correct? Does Bass Redirection send information from all satellites, such as an explosion in the Rear Left channel or a gunshot from the center channel to the sub, or does it only send information from the Front Left and Front Right?

Sorry for all the questions, I don't know how AVR's work, and am looking to get my very first one.

Depends on your cross over settings. For me my fronts are crossed at 120hz. So anything below 120hz is sent to the subwoofer. My rears are crossed at ...110hz..So anything below 110hz is sent to the subwoofer. (same with center)

This is the way the AVR works. There is a jack on the back of the AVR that is intended to be connected to the subwoofer's input. The AVR sends the LFE track of the movie (the .1 channel) to the sub via this connection.

In addition, the AVR can be set to remove low bass frequencies from any of the other 5 or 7 channels via a crossover setting in the AVR. If such a crossover is set in the AVR, it will send all frequencies below that crossover to the sub via the same jack on the back.

So the subwoofer jack you connect the AVR's jack to has no bearing on what the AVR will send to the sub. That us determined by the setting on the AVR. I believe the line in on the Rythmik sub allows you to use the crossover built in to the sub if your AVR or preamp doesn't have one. But if the AVR does have a crossover and you are using it, connect to the LFE jack on the Rythmik to bypass the Rythmik's crossover. I think that's how the Rythmik works.

So Im having problems with my new FV15HP.

Its definitely not there in terms of quality and or output.

Ive tested it in two different ~1,000 cubic ft rooms, at corner, middle front, near placement. Did subwoofer crawl tried all the different settings.

Calibrated it multiple times with onkyo818 audissey hoping that something like that would be the issue. But somethign is just wrong with my version. The driver is hitting its limit way below the spl level its supposed to, the radiator in the back is getting extremely hot at even 50-60% of load.

I know room acoustics plays a big role, but my klipsch rw12d is surpassing this iteration of the fv15hp, so i know somethign is wrong.

Ive contacted rythmik, hopefully i can get it replaced, i really want to love this subwoofer frown.gif because if i didnt get a bad version, then im definately gonna have to find something different. I am confident there is something wrong though,

What's the LFE trim on the AVR (as set by Audyssey)? What's the position of your volume knob on the subwoofer? Assuming everything is constant & the only variable is subwoofer, there could be something wrong with the FV15HP. Do contact Brian for help.

Sorry to hear you have a problem. First, there is a FV15HP_PEQ3 installation guide. It lists the recommended control settings. Second, some customers compare the output between subs by setting the volume setting same on both subs. That is not a good comparison as the volume control on the sub amp is for gain matching, not an indication of subwoofer output. Third, if we want to see if a sub behaves correctly or not (looking for sign of defects), it is best to bypass the extra EQ comes with AVR.

BTW, as you indicated, you will be away for a training of 3 weeks. We can extend the home trial time for another month. In one way, or another, we will sort this problem out.

Just uploaded a video of my FV15HP on YouTube and I figured I would share it with my fellow Rythmik bass-heads. Sorry for the quality the room is dark so it looks very grainy. The candle is 10' away BTW:eek:

I have finally reached subwoofer bliss after years of searching. I can finally sleep easy:)

What about the F25?

Also, why can't I find any Rythmik for sale in the UK. Don't they want my money??

[edit]
The music in your video seemed to have a lot of punchy bass, so I went to that "Chris's new subwoofer" video and it seems to be Tomb Raider Legend's main theme, which a bit of googling lead me to this page.

AG---The F25 is currently unavailable due to an amplifier redesign. Rythmik products ARE available in the UK, in the same way they are available in the rest of the world---Internet Direct.

My husband is already gone for training. Unfortunately, I do not know that much about sound, but I can tell you he is not using an identical volume setting for everything because he is constantly tweaking settings to get the "perfect" sound. He used Audissey (sp?) to calibrate the room (separate calibrations for each subwoofer), he then played with the volume level to get the right sound (he loves full control, so the subwoofer gives him the control, but it is not fulfilling what he is looking for). The thing that makes us suspicious that the actual sub is faulty is two part, first the back gets really hot, so hot you can smell burning and I touched trying to adjust a setting for him and it actually burned my hand (only 1st degree, so nothing big, but it seems unlikely that an electronic is functioning well if it is that hot, we hadn't even been running it for that long when that happened, maybe 30 minutes at that point) and the second issue is that it's not really moving air, you can feel it, but not to the level I would expect, it moves about as much as the much smaller one we had before.

If you can tell me how to check that (my husband is already gone for training) I can look. I know the volume on the subwoofer he was changing, so I can tell you right now, but I don't know what it was at every point (currently, it is just under halfway).

You know the rules, happy dance links must be posted.

Congrats on the E15 purchase.
post #7818 of 15127
You guys are making me jealous.
I am waiting to hear more on the F25, I am told that is 6-8 weeks away...
post #7819 of 15127
Well I've received my E15, hooked it up to my Yamaha RX-A3010, set the AVR to enable the sub, turned all other speakers to small, plugged into the LFE, set the E15 to ON, AVR/12, PEQ off, rumble off, damping 14/high, volume and gain both half...

But...

I hear nothing... mad.gif Tried the test tones, and hear nothing when it goes to the sub. Double checked the cable, even tried plugging into SW2 output, but I still hear nothing!

What gives? Am I doing something wrong? Red light on the sub amp unless I set it to ON, then it goes green.
post #7820 of 15127
^^ the amp is turn on when the green light is on. So if it does not turn on the green light, it may mean it does not receive signal strong enough. I would try turn the switch to on and then plug in the cable, and the other end is left open, and then touch the center pin with your finger to see if you hear some hum noise coming from the sub. When you do this, don't touch the ground shell of the connector. When you use your finger to touch the pin, it injects hum noise into the source. It is a quick way to find out if the sub can receive signal ok.
post #7821 of 15127
Thanks for the suggestion. Before you replied I ended up turning the volume to almost max, and the gain up as well, and then I did start to hear it. I ran YPAO with volume and gain set to 50%, and the Yamaha sets the level of the sub to -0.5, which I just thought strange since I didn't really hear it while music listening. I went ahead and changed the level to +3 so I can at least hear that the thing is running. I'm really not complaining about the sub, but I think I was expecting more bass output than what I am hearing compared to my Klipsch RF-62 II's.... or perhaps I just don't have everything dialed in properly? When I put my ear up to the sub, it sounds a bit "muddy", is this normal at that close of a range? Something just doesn't seem right to me... confused.gif
post #7822 of 15127
^^ If Yahama YPAO sets the sub volume at -0.5db (not some large positive number), then volume level is mostly correct. If you can play some movies, it is a better test for the bass. One of the characteristic of our subs is that the bass is well integrated to the front speakers, you may not hear the bass to stand out that much. So music may not be the best to demonstrate bass. Movies should give you a better idea if the extension is there. If the extension is there, the volume setting is correct, then the only other thing that needs attention is phase alignment. Normally that has to do with the distance setting on the sub. YPAO should set that for you. But if the phase is not aligned, one can hear less mid-bass and that can also cause the bass to sound weaker.

BTW, be sure PEQ switch is off. You don't need any of the top row knobs, that includes gain. Volume setting is the rightmost knob on second row from the top.
post #7823 of 15127
Have you by chance connected the Multichannel Subwoofer INPUT rather than the Sub 1 PRE OUT? Plenty of folks have done it once or twice, clearly they will not admit to it. wink.gif

From what you have described that might be the issue, also the receiver does support two subs but perhaps Sub 2 Out has been connected but the settings have number 2 toggled off.

One possible method to determine if the Amp is DOA is hookup a cd or MP3 player to to the sub's input and select some bass heavy music. If you do this set the gain midway and slowly turn up the volume on the player, in order to avoid any loud surprises.

Good Luck
KvE

PS Thecablemonster, if there is a burning smell it maybe defective. Also there is a small toggle near the bottom of the AMP for voltage, is it by chance set to 220-240V instead of 110-120V? Assuming you are in the US.

Perhaps that's the "problem"... it blends in with my mains so well I didn't notice it unless I put my ear up to it... I will definitely try some movies!

Thanks, I have double checked multiple times, and consulted the Yamaha manual to be sure I'm not insane, and fortunately I have the correct output plugged in. smile.gif
post #7825 of 15127
Do you by chance have Kung-Fu Panda? Towards the end Po defeats the villian and says "Skadoosh!", with my DIY original PEQ370 amp that sound effect rocks my house.
How To Train Your Dragon has plenty of great bass moments. There are several sections in the Star Trek 09 film that has some awesome bass, such as when the Enterprise goes to warp.

It's never fun to have a new purchase not pan out as expected but in my experience Rythmik does provide a great product. My only major regret is not getting the HP kit, although I may save up for the F25 in the future.

Good Luck

Received my FV15HP (piano black) yesterday. Wow! It's a gorgeous unit. This is my first subwoofer and even though I had read the dimensions it still was more imposing in size than I had anticipated. It's huge!

I started by reading the enclosed installation guide and placing all the settings where recommended for an AVR. I ran MCACC (Pioneer receiver) and when it was done I played a few scenes from Iron Man just to get a bit of a listen to it before we had to put our 2.5yo to bed. Like I said, this is my first subwoofer, so I have nothing to reference it to as far as sound, etc. goes. It sounded very good in general. I was certainly hearing sounds I had not head before from the soundtrack.

Later on I looked up the levels that MCACC had set and I saw that it had the subwoofer output at -5db. So...do I need to lower the volume on the subwoofer a bit and rerun MCACC to try to get it closer to 0db?

Also, I realize that I most likely have some tweaking to do yet, but I was slightly underwhelmed by the output. Can I just change the AVR's output to the subwoofer instead? Move it closer to 0dB and see how that changes things?

Any help, advice, tips, etc. anyone can offer me will be much appreciated.
post #7828 of 15127
The non piano black finish on the FV15HP is vinyl, not wood?


Thanks!
post #7829 of 15127
Yes, it's vinyl, walnut or black oak

Yes, lower the gain on the sub a little, rerun MCACC and get it close to zero and then you can bump it up with the receiver.
