Thing is, with Submersives they will be the last subs you ever buy. So while they are expensive up front, over time and money saved on upgraditis, they might actually work out cheaper in the long run. Well, that's how I justified it to myself anyway LOL.

Thanks everyone for the help.

Good news that your sub appears to be undamaged and that the tweak you made helps. It does sound as if you were simply pushing it too hard, and you may be in good shape again, at least for a while. You mentioned SVS. They make very good subs; not in the Submersive class, but I believe still an excellent value overall. I think as a longer term strategy, it might be worthwhile looking at an upgrade to get lower/louder bass. If you do, also take a look at some of the SVS cylinders: the PC12-NSD or the Plus. You can sometimes find very good deals on used ones as people either trade up or move to smaller places where they can't use them anymore.

I believe I remember seeing you over on the Atmos thread. If so, you probably really enjoy the movie experience, and getting more/better bass might be an important aspect of that. Going from your current 300 watt sub to even a single Submersive (much less a pair) would be like going from a Pinto to a Ferrari. But the advice to consider an upgrade may still be perfectly valid. You may just need to approach it a little more gradually. I hope you don't mind me weighing in on this.

Regards,
Mike

Thank you Mike. I welcome your advice.
Do you think the cylinder subs perfrom better than the traditional boxes, or it's just a design compromise to accomadate into tighter space?

I don't think there would be a measurable or audible performance difference between equivalent models of cylinders and boxes. But the cylinder isn't a design compromise. SVS started with cylinders, because they delivered good performance in a smaller footprint, and for less weight, than a comparable box would have. The weight can be a factor if you are moving your sub around. The cylinders are not difficult for a person to manage by himself.

According to SVS, the cylinders are also about 10% less expensive than comparable box models. I was suggesting upgrading to a 12" woofer rather than another 10", and because cylinders are more popular (and plentiful), I think you would probably be able to get a better deal on one.

I agree - I used to have a pair of SVS PC12-NSD cylinder subs - they are fantastic performers for the money. aaranddemann would not regret buying one (or two) of those.

Also, of course, a cylinder is an inherently very strong form factor allowing SVS to squeeze terrific performance out of the sub for less weight, less footprint and less cost.

aaranddeeman, I have some doubt that recalibrating your system could really solve your problem. You went from "big stone in sub cabinet bouncing inside" to "it's not so bad".

Think of the re-calibration like this please. Audyssey set your sub to reference level. You had a -11.5 dB sub trim with gain knob on the sub between 1-2 o'clock. Now you have a -5 dB trim with sub set to 10 o'clock. Nothing changed, the SPL delivered by the sub remained the same with both calibrations.

On another note, neither the -11.5 dB nor the -5 dB would drive the preamp of the avr and the plate amp of the sub into clipping.

You just decreased the signal input of the sub, yet increased the signal output of the avr. The big stone doesn't seem to be an electronic issue in this case.

Whether you'd like to investigate your case in more depth is up to you, of course.

I am listening...
I thought the same way when I was going lowest on sub trim setting by Audyssey, but...
I would sure like to investigate further. Any help is appreciated.
Just to be clear, the bad behaviour is mainly like when "building collapsing on each other with explosions" . Seems like sub is trying hard to reproduce the sound but may be reaching it's limits.

The post's unique ID is 22996795. I cant understand why the link doesn't take you there - the idea of the unique ID is that it is, well, unique, and a link can’t go anywhere else. Odd.

You saying the link doesn’t take you to Roger's post either? It has nothing to do with the ppp setting - the unique ID overrides all that which is why I always use unique IDs for links. If the link doesn’t take you there, then AVS is broken somehow.

As you have described it previously this also happens at -22 dB MV. Hmmm, a broken sub?

The first "this post" link in the FAQ section referenced (after links to Roger and Mark) takes me to the top of p. 115 (out of 129) or here:

Weird. The whole point of using the unique ID is that it overrides everything else, such as ppp, deleted posts, user settings etc and refers directly to the AVS database. It must be broken in some way - we do get a lot of 'database errors' in this thread, so maybe that has a bearing on it. There's nothing I can do - if I link to the post in the usual way, then anyone with a ppp setting of anything other than 30 is guaranteed to be taken to the wrong place.

Incidentally, do the other links work for you? Try these:

a)2. Why is dialogue from the centre channel difficult to hear or understand?

c)5. What is the LPF of LFE and what should it be set to?

f)7. What is ‘LFE + Main’ or ‘Double Bass’ and should I use it?

(They all use Unique Post ID too.)

Yes, all 3 links work fine. Incidentally, I'm on Windows 8.1 with IE 11.

Are you sure that all of the posts are using unique ID's? When hovering over the posts, I get a short description if the link is a Unique ID:



and nothing shows up on the links that aren't working:

Hi all - I have a problem that might by Audyssey related so I was hoping you could help me out.

Equipment:
JTR Noesis 228HT LCR, JBL 8340a surrounds.
Seaton Terraform x2 subs
Denon 4520ci with XT32

Here's a frequency response after running audyssey:


When I look at Audyssey and check the eq it is using, it shows me this picture which makes it seem that Audyssey itself is causing the 125hz suckout. Is that the case?

I can't remember of course if every single AVS internal link has been corrected. I know it took days of work to fix the FAQ after they downgraded to VB from Huddler.
