[QUOTE="Ivan Beaver, post: 89338, member: 30"] Re: Small-ish Home Theater Subwoofer OK-this is gonna piss some people off-so I appologize in advance. I thought that Bennett was pretty clear about what he wanted to use as a driver-what he wanted it to look like-performance objectives and so forth. So jumping to other layouts/designs that are clearly not what he wants-is kind of useless at this point-At least in my opinion. Unless he is willing redefine his needs. Now to the crux of the matter. I think it will be pretty hard to get to the target response with that particular driver in a regular dual configuration. It is designed for a higher tuning. HOWEVER you might consider a isobaric configuration. It will require 4 woofers (but he knows where to get them :)) and can extend the low freq response by making the box "appear" to be twice as large. The penalties to be paid are twice the driver cost and more weight-neither of which probably are an issue to him. [/QUOTE]
