Carnegie Acoustics got in a shipment of CSB-1's that did not get the polyfill properly installed. And instead of un-boxing them all, and fixing each one, and re-boxing it, they are just going to mark them down to a ridicules price and move them.
These speakers are a really nice looking gloss black. And yes the use the OEM version Neo 3 pdr.
Grills are held on magnetically.
They even come with tube connectors. Yep a $59 a set of connectors that are better than any binding post on the market. As you can see they are also rear ported. They will hit a -3db of 55Hz.
Just remove the woofer (six Allen head screws). And pull out the wade of insulation.
As you can see the crossover uses high quality poly caps and air core inductors.
Then re-install the insulation covering the side walls and crossover, but leaving a nice little pocket behind the woofer and leaving a clear path to the port. And now your B stock speakers are A stock.
These retail for $899 a pair. See more info on them here: http://www.carnegieacoustics.com/#/products/Now you can get a pair of these for $399 a pair plus shipping.
Just call me at GR Research to order them and I'll even handle the sale. 940-592-3400
