Re: Build my own subs
In some cases, I think that makes sense. But you can't fix everything with signal processing. Setting a delay or making a filter is easy, but some acoustics problems can't be solved that way. Two examples that come to mind are cone breakup and destruc...

Re: How Many Speakers For A Home Theater System?
Most home theater systems are for five channel, left/right/center and a pair of surrounds. Some are for seven channels, a left/right surround and a pair in the rear. Either of those configurations are pretty good for home systems, I think, with one spe...

Versions and Upgrades
I agree with your assessment of the crossover. The new version (2007) is an incremental improvement over the original, not a night-and-day paradigm shift by any means. The basic design hasn't changed in many years. But having the latest version of the...

Re: 4 Pi build for HT
I'd love to see NWCgrad's build pics too. As for the internal bracing, yes, of course, if you displace too much internal volume you can affect performance. So the obvious reply is "don't". It is designed to have an internal cross-brace and t...

Baffle Step
In my opinion, baffle step compensation filters can be useful, but only for a fairly limited number of loudspeaker types. I think they are way overused in the DIY community. BSC filters are best suited for little mini-monitor speakers with small baffle...

Re: Multiple Subwoofers
I have seen a home theater setup where all the speakers are embedded on the walls. The wall is made up of wood on this home theater room. Do you think embedding multiple subs on the wall would be ok? I have feeling that it might damage the walls because of...

Re: Multiple Subwoofers
Crawlspaces are a problem because the chamber underneath the floor forms a resonator that can cause peaky response. It will suckout some sub frequencies and leave others very loud. Other than that, if you have a concrete foundation, I'd say the floorin...

Re: Multiple Subwoofers
I agree in all aspects except the points of asymmetry and number of corner sources. I realize you know my position in this matter but I'll restate just in case other readers don't.
There are two schools of thought on this, one championed by Todd Welt...

Re: Multiple Subwoofers
For the record, I'm another advocate of multiple subs. While intuitively it seems like overkill especially in a small room, the reason to go with multiple subs is bass quality, not quantity.
The smaller the room, the farther apart the room-induced peak...

Re: Multiple Subwoofers
Multiple subs are the only way to go in my opinion. It's done more to smooth out room modes than to increase SPL. The idea is to place them around the room in different places so self-interference that is destructive from one sub is filled in by anothe...
