Plans for a mid-bass tractrix horn?
 
Guys, I want to pursue something like this:

Bass cabinets

But I need better plans. Is there anything else out there like it? Seems pretty ideal for blending with my Unity horns at ~300hz....and it goes down low (enough - 45-50hz).

Thanks!
Jim

Dual 15 PPSL is probably your best be to match up with a Unity Horn as it will provide uniform dispersion between the sub and the horn.

Moray, can the dual 15 PPSL run up high enough (300hz or so), frequency-wise, though - and if so, does it sound good that high?

Thanks for the idea.

The PPSL should be able to reach up to 300Hz, but it really depends on the drivers and the geometry of the cabinet's slot.

I don't think I agree with the above statement that the dispersion is necessarily going to match between the two sections.

Guys, given my application, what would be the recommended PPSL design and 15" driver complement?

Thanks,
Jim

Don't limit your selection to just 15in drivers.
Do a search here (and audio asylum) for PPSL and DJK.

Expo 15 since this is what you were asking for I think.
Info on how to blend a PPSL woofer with a Unity Horn about as good as it gets.
William Cowan's Homepage look under heading of Unity Horn. Best regards Moray James.

Sounds terrific, but it's not push pull.

Guys, I like Eminence drivers...how about plans for 15" Eminence Kappa PPSL? I've done a LOT of searching and can't find actual plans for such cabinets.

Thanks,
Jim
