Introducing the new CSW-450. This is a special design made by ALK Engineering and manufactured by ampsandsound. Its a combination of the “CSW” Cornscalla-Wall Universal and the AP12-500. The CSW section has a slightly improved tweeter filter and the woofer filter is now 2nd order. The low crossover is at 450 Hz. This makes it ideal for the LaScala and Cornscalas that use the Fastlane Eliptrac 400 midrange horn. This a perfect upgrade for those wanting improved bass without the desire to step up to higher order filters. Build time is 4-6 weeks depends on parts availability. We often have 1 pair ready for delivery.
