Would this driver be a good replacement for a cerwin vega atw 12?  I'm rebuilding a pair of At 008764 cerwin vega 3 way speakers. Thanks for the help in advance!

Asked by: dumpsterdiver
This is aimed more for a pro audio application. The woofer we recommend for the ATW-12 replacement is the Series II below.http://www.parts-express.com/dayton-audio-st305-8-12-series-ii-woofer--295-120

Optimum Cabinate Size?

what would be best to support bottom utilizing this speaker as a sub? Thanks for the help.Larry
Asked by: Larry10
In the information area on the product page - download Eminence Delta 12A Suggested Cabinet Design. It's a good starting point. From there, if you don't like he resulting performance - you can use a box calculator to see other options. Often - you will have a goal and after using a box calculator will find that the driver you want doesn't fill the bill. This is where you do your homework.. Have fun !!!
