SA-8 v.3 In Development : Getting Close !


Recommended Posts

I measured a production v.2 and a newly re-built v.3 with the final compliance side-to-side with the same amount of play time (neither is fully broken-in). Just to compare... looks like we nailed the stiffness based on FS... and we see a drop in Qts due to the higher BL (also higher sensitivity) :

BL^2/RE = 70.17

BL^2/RE = 85.78

-----

I don't trust the Woofer Tester as an "end all be all" of spec measurement either so don't read too far into it... but comparing on the same day back-to-back I can tell if my design goals are being met :)

The spec on our web-site for the SA-8 v.2 was done with a Klippel machine after full break-in for reference.

Nice!

When is the new sd-8 coming out?

I concentrated most on the SD-3 10" model; which is now complete and about to start production.

I will likely do the 12" next; then the 8" last since it is changing the least in it's revision to SD-3

I don't have an ETA for it yet, though, as I still need to go through all of the development and tooling.

The X-8 standard spider is more of an "SPL" type geometry.

We could stack more together for your on a drop-in, though.
