Re: The Subwoofer thing
I think that you may be missing the point. It is important to know what the best approach is so that we can move in that direction no matter how far to that extreme we go.As far as multiple subs go, I would never buy several expensive subs. But I would s...

Re: new subwoofer
I can't imagine anyone using them for home hifi use, and in fact would encourage them to use multiple direct radiating subs instead. The multi-sub arrangement is more home-friendly than a massive hornsub and it has the advantage of smoothing room modes. ...

Re: One driver for FULL spectrum or one driver for critical portion of spectrum?
