I decided to make one of the best deals on sub-woofers even better and run them on sale.



For the rest of the year our SW-12B woofers will be on sale for $89 each.

I don't know of any better sub-woofer value on the market at full price. Now it is one of those no brainers.

This woofer will hit a -3db in the low 20's in a ported box and a -3db right at 20Hz using the matching PR. It even works well in a small sealed box of just 1.2 cubic feet.

You can even order it on line. http://www.gr-research.com/index.asp?PageAction=VIEWPROD&ProdID=131

Hi Danny

I am interested specifically in a servo controlled sub. Are these the drivers that will work with the Rythmik servo amp?


Let's hear it for economic stimuli aa

Danny what is the -3 in the sealed box? What is the best blend for the OB7

[Danny Richie]

Nope, the servo subs are SW-12-04, SW-12-08, and SW-12-16FR.  All of them are $149 each.

Danny what is the -3 in the sealed box?

About 42Hz in the sealed box. But if you are setting the crossover at 40 or 50Hz then you have taken away from the top end as it has already started rolling off. So your new -3db point may be where it once was -6 or -8db down, and that could be 30Hz or less.
