This must be the most anticipated driver of the year!
yes, very exciting and something to look forward to 😎
The preview data sheet is currently being reviewed for publication. Here is a sneak peek

Take my money!

Seriously, that's looks great. Any hint on how large a sealed box would be with it?

I am currently using the PTT6.5 in 8L sealed matched with a Bliesma T25B6. It goes down to around 85Hz and below is picked up by an array of subs. I listen to mostly symphonic music and the PTT6.5 is spectacular in sound with such complex music. However, it is a bit strained when played very loud. It has bottomed out in some music. I am hoping the 8" will provide a bit more headroom in the bottom end so I can push the sub down to 65Hz, and then have the extra Vd to handle a bit more loudness.

This will be my end game build. I have been looking into how to fill that 65Hz-85Hz hole and contemplating some 10" or even 15". The Satori WO24P has a rising HD below 100Hz and the box need to be 60L. I have JBL 15" which has -55dB HD all the way to 60Hz but it will need a 150L box. I would pay extra to be able to have a smaller box. And these days, the saving in wood money should be worth the anticipated extra cost!

thanks! What Qtc do you want for your sealed box? we hope to so a version with a softer suspension that works better for sealed (reduces box volume). But sealed would achive an F3 around 55Hz for Qtc=0.7
 
It is uniformly 10dB better than the PTT6.5X !
I'd expect at least 3-6dB better, but 10dB is great!

A bigger cone will reduce distortion and increase sensitivity. but what's more remarkable is the smooth response out to 2-3KHz, without any funkiness in the cone-edge termination. This is definitely an unrivalled 8" midwoofer.

Lar's, what's the frequency at which the 45 degrees off axis drops by 3dB?

looking foward to the expansion of the line...

best regards,
Thanh

PS. I have also cabinets with dual 12" woofers holes being made for another peerless 280/309/5mm basket woofer. 🙂
