These are some new PROTOTYPE SD-2 line 8s designed around a sealed box and shallow mounting (4.75" deep) -- I expect these to hit market October 2012. These are a line below the SA-8 v.2 in terms of power handling and cost.
Obviously this is not intended to be a mind blowing bass demo -- but for a TINY sealed box the output is great. The SD-8 is also an under-hung driver so features very low BL related distortion characteristics. It is by far the best sealed box 8" woofer we offer and one of the best on the market; especially with cost considered.
