*Update

I ran Audyssey again and one sub was set to -8.5 and the other -2 when both subs were gain matched. Not quire sure how you are getting identical trim levels for each sub channel after calibration.

If your goal is higher output, you should look into doing a DIY.

A Mini Marty + Dayton UM18-22 + inuke6000DSP. The dual set-up would come in around $1600-$1700 and would yield a performance upgrade over your existing set-up.

You use lfe in on subs right? Peq is off, etc... Make absolutely sure all knobs (frequency, dampening, etc...) are exactly the same for both subs. What are the distances set by aud?

Measure each sub independently( gain matched )and compare the difference in output with audyssey off. It could be one sub is getting more boundary gain then the other. That being said 6db seems extreme.

+1 if one wants high output for cheap and don't mind HUGE box.

I don't think you would save that much money going diy compared to how much the Echo 18 cost...especially on sale right now for 1199.00. The savings would be on the second sub because a single amp will drive both units. However I do not really think comparing a Inuke to Ice power is apples to apples either.

^^ Agree but no DIYer just builds one sub. They build 2 or more, in most case 8 or more

Definitely. The Echo 18 is an incredible value at its price point, especially considering the driver and amp that goes into them.

That's because it's relatively affordable. I literally just got into DIY 3 days ago and I'm already up 4 subs... in my case, I shouldn't really call it DYI, more like PSE (pay someone else) lol

Correct, LFE is used, gain knobs the same, PEQ off. Distances are 11.5 ft and 11.9 ft.

I've explored DIY as well and I know about the guy who started offering the Marty sub flat packs again. He is located in Texas, but his dad is the one who cuts and ships the packs from Iowa I believe. I have definitely given DIY a strong consideration.

One sub indeed is getting boundary gain as it has two adjacent walls right next to it. The other is on the same wall, but not corner loaded because the front door is right by it.

Distances are very close from the 2 subs to mlp. Not sure why it sets 6db difference between 2 sub level. Are you sure all other knobs are exactly the same?

I've counted the clicks on both gains, but I'll count them again just to be sure when I get home tonight.

^^ I am asking about the dampening, frequency, 1 port 2 port knobs. Check to ensure ALL knobs are set exactly the same as it makes no sense there a big difference in sub trims set by Aud when your subs distances are about the same.

I checked all that multiple times as well. Do you think there could be some sort of defect with one of my subs?

^^ If you recall from some pictures I recently posted my sub on the left is corner loaded with two adjacent walls and the other sub is corner loaded as well, but the wall cuts off. What I don't get is Audyssey is setting the sub on the left which truly is corner loaded a lot louder than the one on the right. You would think it would be opposite since the sub on the right doesn't benefit from the walls like the sub on the left. I don't know now I'm getting confused dammit.

I like those silver cones!

Just for the heck of it... have you tried resetting your Denon? My 4520 was finicky a few weeks ago so I scolded it and reset it. Ta-da!

EDIT: Hard to see from those photos, but couldn't you turn your whole setup, 90 degrees counter-clockwise? I mean, having the window that is now behind the TV, directly to your right? IMO, I would stop shifting the subwoofers' locations just a few inches, and go ahead and do a complete layout change. If it doesn't work, well, go back to how it was.

Yippee-ki-yay...

Thanks! You know what I'm gonna have to think about doing an overhaul on the room. I'm gonna have to think about this when I get home and can get a good visual on where everything could go. How do you go about resetting the receiver? Unplug?

Before resetting the Denon, try swapping the two subs and rerun aud to see. The next step is resetting your Denon. It could be your Denon output voltage problem on one of the sub out or one of your sub itself. Which sub is set to -2? The left one? It's a good thing you try gained match as you wouldn't know this discrepancy if you didn't.

Simplest answer is usually the right one. Did you gain match just by equal knob clicks? If so they prob ain't the same...

If not, here's an image that explains.

I know you have done a lot of measurements lately, but have you measured each sub individually to see its response? It is possible that your corner-loaded sub by itself is producing a couple dB more output that the other one, but also produces a broad dip several dB deep at your listening position. Or, on the contrary, the non-corner loaded sub could be down a couple dB from the corner one overall, but have a broad peak of several dB at the MLP. Either of those scenarios (or the two in combination) could be "fooling" Audyssey wrt how loud it is setting each one.

Although I also agree that just because the amps are set to the same gain visually, or by click, doesn't mean they are necessarily identical in output.

In addition to low distortion, a key parameter if you want true deep bass and not just thumping overtone, the ability to start and stop cleanly without ringing makes any percussive effects (piano, guitar, drums, cymbals, cannon shots, explosions) much better. Blending with my Maggies or other "fast" speakers is always a challenge. My first sub was a servo of my own design and I have not looked back.

Most people who "hear" their subs are hearing harmonic distortion and ringing. A good sub is best known by its absence; turn it off, and the whole musical experience suddenly seems more "shallow" -- thin and weak.

All IME/IMO - Don
Stopping and starting quickly---exactly! When a bass player pulls on a string, it SNAPS. When the string slaps back against the fretboard it SNAPS again. A bass drum pedal's beater SMACKS into the bass drum head, creating a very complex waveform comprised of the fundamental plus many layers of overtones---very difficult to reproduce well. Loudspeakers are in general good at reproducing the harmonics of the fundamentals of the bass notes being played as quickly as required, and if a woofer (and/or subwoofer) doesn't start as quickly and stop as quickly as the loudspeaker, you hear a discontinuity between the two---the bass fundamentals sound disconnected from the harmonics (overtones), slightly behind them in time, both when a note is struck and when it stops. The bass lags behind the higher frequencies, distorting both the timing of the music and the timbre/tone/texture of the instruments and vocalists. That's why Hi-Fi perfectionists have long eschewed subs, preferring not enough bass to "slow"/disconnected bass. One no longer has to make that choice!

I did and even just swapped their positions with each other and counted clicks as well as visually saw both subs gain matched at the amp level.

I love the matte black finish with the black drivers. That finish doesnt show finger prints or anything like I have seen on other glossy subs.

I ran Audyssey again and one sub was set to -8.5 and the other -2 when both subs were gain matched. Not quire sure how you are getting identical trim levels for each sub channel after calibration.

BTW, the gain on H550 may be slightly different from H600 because they are from two different batches. Using an SPL doing a close-mic measurement is more accurate. Since the FR is the same for all 3 subs, pick a frequency warble tone, say 40hz, and do a reading for each sub. Then you know for sure they are level matched. No need to even open up your computer or take out your tripod. BTW, when you do close-mic measurement, it does not even matter if your dog is barking or any kind of noise.

JT, I guess to gain match, you will have to place each of your sub in the middle of the room with no boundary, place your umik right in front of the middle of the cone, use rew tone generator to achieve about 80db or 82db since you like to run subs hot, do the same for the other sub at exact sub and mic position. I would use masking tape to mark the sub location so that it's easy to place the second sub there. Try not to move your boom mic between sub swap. Place both subs back to where they are supposed to be and run Aud cal.

I just had to give you a like for this post. I am so happy to see someone who did not use the word "of" where the proper word is "have". It seems every other post I read lately, people would "of" or should "of" done something. The only bigger pet peeve I have is when people say something like: what is "are" expected shipping date, rather than "our". I really don't see how those two words get confused.

I suppose I should of expected no different based on are education system.
