  • Driver selection help for floor standing towers

    looking for some input on what woofers and tweeters to use in a set of sealed cabinets. I'd like for them to have a roll off of around 50/60hz, I have a transmission line that's tuned to 20hz that plays from 10-50hz so the towers don't need go so low. I'm wanting to go sealed so I don't have the nasties that comes along with ported mids and lows in different cabinets.

    I'm thinking 8" woofers should be the choice to reach that low in a sealed cabinet, or are there any 6.5s that will reach that?

    So far my idea is 4 8" woofers and 1 tweeter per cabinet also looking at Morel, Aurum, Dayton Epique, Wavecor, Peerless, etc.

    Use the (free) WinISD program from and go nuts! Bottom end reach isn't determined by driver dia., but by Qts and Fs. Drivers w/a Qts near 0.40 and an Fs in the 25-30 range should get you where you want to be.
