Just got these in... designed them based on many requests for a really good sealed box 8" woofer. Power rating is pending testing but mechanically I designed them around 300 watts or so (half the spiders of the SA-8 v.2) -- we'll do our thermal cycle to determine the official rating. As is typical with our products the rating giving will be a "worst case" rating and many people will have no problem running a bit extra.
We built upon our newly tooled platform from the SA-8 v.2 so it shares many of the advantages of that platform from the get-go.
These feature an under-hung coil with predicted linear x-max of ~14.5mm one-way by 70% BL method using an 8-layer copper 2" coil with 1/2" of winding width.
The total depth for mounting is right at 4.75" measured,
I will be measuring actual T/S on them later on today after some break-in time. Pricing is also pending final costs from our parts suppliers.
On to the photos :
* E8 v.2 then SD-2 8" then SA-8 v.2
* For this design I used drilling in the basket as opposed to the vent ring to save depth.
* Solid pole like the other SD-2 woofers so there is no need to leave room to breathe behind them.
* Same spider as the SA-8 v.2 but only one layer (top layer)
