Sarang, Ian pointed out the major reason why subs, for the most part, don't make use of non-parallel sides for the enclosure. The small "room" that the inside of the enclosure forms follows the same room mode rules as do our listening rooms. If the modes that would exist in that "room" are well above the frequencies that the sub actually plays, then reducing or spreading them out wouldn't be of benefit. For example, calculate the modes for a room say 1.2'x1.5'x1.8', or more conveniently, use a calculator such as this one . Note that the resulting standing waves inside the subwoofer "room" are all in the mid-range and far above what frequencies are actually played.

For loudspeakers though you would want to avoid resonance frequencies in the mid-range at the very least. For subwoofers though how can it be a bad thing to raise the resonant frequency?

That said some of the best possible performing loudspeakers like the Revel Salon 2 have very, very inert cabinets, on the opposite spectrum, the Infinity Primus are basically hallow cabinets but still offer very good performance. Controlling cabinet resonance I think would depend on a lot of factors and not one that is a matter of being absolute. Its like a lot of tradeoffs in loudspeaker design.

That is awesome, I want one! When do you think it will be available Ian?

That really dwarfs the 150, which will work out great using the 160 above the TV screen and 150 below, can't wait!

BlueJays1,

The points you are making are exactly what I am going to cover in my upcoming newsletter piece on bracing. It seems like it is going to be a very timely article given the current discussion.

Hey, I explained it first. Ian just didn't use the Bran Muffin analogy. I guess I lost points for not being staff or not being the slightest bit eloquent.

Ian is, admittedly, much more knowledgeable than I and he has Shania Twain's Summer Home on the other side of his lake. I can't compete with that.
I humbly concede.

Here is an AES publication on this very topic. JohnK probably already has it in his collection smile .

All of a sudden My wife Tina is getting agitated and she doesn't even know why. She must feel the "disturbance in the force". Looks real good so far!

Still waiting patiently for more on this, hoping it will be ready for purchasing soon; Santa could use one.
