At the 2004 CES we'll be showing a 24" square baffle unit, with a Qts of 0.72 and an Fs of 7 Hz. Flat anechoic response to 6 Hz. And capable of over 66 liters of linear air displacement! That will generate reference level (121 dB SPL) output at 20 Hz, when sitting naked in a room - no room gain, no baffle, no box required. The first true dipole driver (not sub - no baffle, remember!) that can do reference outputs. With flat output to the single digits. How's that for a driver?

Now this is goddam low fs, sealed box lover save your bucks

Skinnyboy, I think the pionneer monsters are just been stunned by those adire with 12'' of Xmax isn't it

Simply not the case, only when measured nearfied.

The baffle will roll-off 6dB/octave below 300Hz farfield.

ye cannea chage the laws of physics, laws of physics, laws of physics, ye cannea chage the laws of physics, laws of physics, cap'n.

Its life jim but not as we know it, not as we........

Ok ill be quiet but sreten speaks truth.

From Adire:
..figure in the $4500-$5000 range for most "normal" application.

The Dipole Bass Contingent is applying for second jobs and taking out additional mortgages even as we speak...

I thought there wasn't a baffle to this thing? Why do they say square baffle then say there isn't a baffle?

looks interesting to say the least. I know adire has both enthuists and enemies here, anyone wanna discuss this monster?

By this point, Dan's out of the world of audio and into the world of industrial linear motors. Provided he can find a springy suspension to hold the voice coil, he is to the point where he could effectively market an electrically-operated sonic jackhammer that would probably just power through concrete and stuff.

That 24" square "baffle" is the cone, BTW. And assuming a rising magnitude to overcome the roll-off that's not strictly true (can be done easily electronically).
