Decoupling works and where that isn't feasible you can use conjugate force matching where the violating waves are effectively cancelled out. Both methods are expensive!

The price is guaranteed to empty my wallet too ;)

Actually, to be technical, with the amount of plastic, it won't even make a scratch! :Q

edit: Do any of their other models have custom ear impressions? If so, I could consider getting maybe a pair of 12" Daytons and an iPod Nano with some nice headphones instead of one nice SVS sub...

Actually if you got bass dampening foam.. it will cost A LOT more than the ultimate ears.
A square foot of bass dampening foam that actually WORKS, starts at about $50 if not more. So if your wall is 10x10ft, then yes, that's $5000.
That's partly what I was expecting to be honest, looks like I may just have to get a PCi and call it a day for now. Maybe sometime in the future I can make more of an ideal room to listen to music and movies in? I'm probably a good 7-10 years away from that ;)

Sounds like someone might have been better off buying a certain used PB10 ;)

Reposition the sub in the room so it's not using the walls as extensions of the speaker. Put a thick blanket around it?

I would build a frame that's not attached to the current walls and ceiling. Build a square frame with triangulation and bolt them to the concrete floor only. Cover it up with 3 layers of 5/8" sheetrock.

yeah, that is a good approach...but you still can't get past the fact that a sub is a sub and it will compress/decompress air (like any speaker, but with much more energy)

I like the approach of positioning and another transducer the nullify the effect - nice idea...never done it but it makes a lotta sense.

Hmm... where should I try positioning it? I had a bed in the back of the room, desk in the middle on a side, and the setup in the front of the room. I can reposition things if it helps.

well what do you want?

Best response at listening position or don't bother the parents?

easist way for option one is put the sub at your listening postion and walk around with test tones playing and a SPL meter in hand.

Yeah, I'll do that and play around with it once I get the subwoofer, not exactly sure what I want at this point ;)

Don't fight fire with fire now -

What is the ambient sound level like? If it's 20 dB or less you're doing ok as you can enjoy 75 dB of dynamic range and still be under 100 dB. Of course if you have the bass cranked with room gain you can add another dime to this which puts the thump at the brink of carrying past a storey or two.

If you listen to pop music you're basically screwed as its dynamic range is flattened. Sounds like you need to establish a time table when others are not likely to be present and you can crank it as you wish. :)

you get an SVS and you're parents aren't gonna like you very much.

;)

But in all seriousness the dynamic compression features of your pre-proc/receiver will help a lot. Dolby digital and DTS have built in features to do what you ask.

Sure they sacrifice sound quality to some extent, but when there are others in your house they are very useful.

in other words...

RTFM.
;)

Playing obnoxious volumes at appropriate times ftw!

hahahahahhahahah....

say it isn't so....pop and dynamic range of only 10 db?

nah.

haha, my parents don't really care at all except when they're sleeping :)

We do have one floor inbetween us and my room is on the opposite side of the house so that helps a little although apparently sound loves to travel ;)

RTFM?! Nooooo!

Yeah, I'll read through the manual a bit more closely and understand the different configurations and settings once I get the subwoofer.

As for music, I listen to just about anything, classical, techno, lots of classic rock, etc.

Well technically the real deal is unweighted average crest factor. A CD has a dynamic range (useable) of about 90 dB. Most recordings use a fraction of this as the popular consensus is louder is better. :disgust:

A 24/96 HDD recording has a range of 136 dB and that is enough (if used correctly) given the right playback environment to scare the poop out of most people.

Of course most pop music is as tasteless as it is dead in the dynamics department. It's just not musical.

Of course you don't have to have ultrawide dynamic range to enjoy the performance. Some real R & B sets a good example. :)
