How About These for Dipole Sub?
Beat to the punch by Milo :^)

This driver has such a large Vas, that either an open baffle or the next room as box are all that is practical.

Its displacement is about 1.15L, which limits you to a maximum of roughly 86dB at 25Hz at 1 meter (taken from Linkwitz's OB spreadsheet).

EDIT - given a 500mm path difference

is this the wrap-around distance between front & back?

If it is, the FW800 would have a minimum of 800 mm being an 800mm driver... larger would be more likely.

My dear apologies! That's not the maximum SPL, that's the sensitivity!

86db@1W@25Hz isn't too bad... But you can't get much louder than that at listening position, I would think.

Ignoring any baffle/room gain, it calcs to ~91.63dB/m/18Hz, 103.68dB/m/36Hz, 115.72dB/m/72Hz at Xmax, so not too shabby once the room is factored in. Still, you can buy a lot more Xmax and the power amps to drive them for $2446.

I'm running two pairs of the Dayton 15" IBs in W-frames, and am quite happy with the performance...

Peace
