* Same spider as the SA-8 v.2 but only one layer (top layer)

* Solid pole like the other SD-2 woofers so there is no need to leave room to breathe behind them.

* For this design I used drilling in the basket as opposed to the vent ring to save depth.

* Left to right : E8 v.2 // SD-2 8 // SA-8 v.2

The containers with these should be in the port of Charleston around Dec 20th -- depending on holiday delays to get from there to us they may arrive before end of December so pre-order NOW if you want some at this price

These are now in stock so the pre-order is over.
