Novicaine I know i said foam in the box will help eliminate standing waves, this is only true for inside the box which has its own often.

A room will always cause standing waves but you can place the sub a certain way.

The more subs you have the better it is for multiple listening positions.

With one subwoofer, if you have a good sized room there will always be listening areas that will reveal room modes wich messup the response from beeing smooth.

More subs placed away and correctly if you learn how, or just listen for it even will not gain you a whole lot if ANY extra output, but will make it better for other listeners in troubled positions with a single sub. Placing the subwoofer makes a world of difference. SPL can kiss my asz if the bass dosn't sound correct. Alot of people are likely experiencing standing waves with there setup and may think it is too much but if you learn to place it then you will enjoy it with the same power instead of turning it down. The smaller the room the more strange it can get for the lowest frequencies.

cwruck like said above a couple hundred watts can be too much.
me i absolutely love home audio much more than car audio, and just for fun i have built an insane set up. have upgraded wiring in the living room to 30 amps instead of normal 15 or 20 amp fuses. and im running around 2000 watts rms off 4 12s in a ported box.
not a single window in the house i cant get to shake. its basically as impressive as a car stereo with a ton of power, you can really feel the bass and its so loud its kinda scary lol
but like said with an efficient box and a couple hundred watts at most you will be set

My uncle is an ht freak, a fast processer on his tv, and a his recieved cost grands but I dnt remember the cost, I don't know what subs he has but it kills a movie theater by a mile. And the sq is setup nicely too. Best ht I've ever heard.

I'm sure plenty of people using caraudio subs will windup getting a response they think is nice and loud but when they learn how to build the right box or get the right subs is when the ht really amazes you.

You have to learn some and get the experience before you realize the best types of subs to use.

If you go sealed with a moderate amount of power like 150 or so the make sure suspension is compliant(loose). Sealed will kick butt and sound better if you get a subwoofer with decent compliance and a good size box for it.
Honestly, my setup kills the movie theater. My know-nothing wife even commented on it. I'd rather watch a Blu Ray at my house than watch it at the theater. Better bass, more realistic surround effects, and no annoying people to deal with.

Novicaine Foam should kill standing waves but i dnt know if it helps for HT...Iv'e seen it so it probly is worth it. It would be easy to just try it so why not.

MopaRBumpiN Alot of helpful info, thanks everyone. When building the sealed enclosure, should the inside have like any foam or anything?
02-06-2011 05:24 PM
Novicaine Sounds good to me, i would love to try that sub if it is truely linear that much, thats perfect! Nice sized box too.
02-06-2011 05:15 PM
surreal In all honesty, an SA-12 would make a great HT sub. It has a (predicted) flat response in [email protected] if I remember correctly. Could go lower as well, room gain 20-40hz will flatten it out.

You are good to go...

What it is and why it works: A heavier cone is more "inefficient" but that getts put into the subwoofers ability to rolloff slower below the F3 and will have a more lower FS and lower F3 which means more efficiency down low rather then above.

"Lower level" subwoofers like the level 2 are actually good for HT if the cone is heavy but it may just have that higher Qts because it has a small motor, but will work good still. You can get more SPL with lows by using a bigger motor and even heavier cone and have great response, but in an avg HT you dnt need much motor as demonstrated by alot of HT subs out there.

The level 2 has an FS of 33 which is okay, but could be nicer with a lower one. Did you buy it yet?

Get a relatively small motor like an re se motor, 12, 15, or 18" cone bigger the better or something heavy, do a big box and seal it on a few hundred watts! Even 100 is cool.
