* 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

I never installed it ported in my vehicle as we designed it mostly for those that want to run sealed. Sean, owner of sundownonly.com, borrowed one for a bit and ran it ported -- you could shoot him an e-mail and see if he has a video handy //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

I could do something crazy with a bunch of these along with a few amps.

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 //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif
