I've still got the Martinelli maple horns with TAD2001 drivers attached, can't bear to sell them, and I'm now looking to build a two way, crossing the TAD over at the min. 800hz. Like to stay low order xo, not worried about power as I'm using the Yamamoto A08 45 amp.

Very interested in the hemp drivers for the bottom, but I don't know of any Mac-compatible box software, and I'm not finding response curves, so I'm at somewhat of a loss . . .

I'm eyeing the Tone Tubby 10" SuperBoy, (designed for electric bass), whose specs are as follows:

Anythoughts, suggestions guys? TIA !
