I am hoping someone knows of a good place to buy JBL drivers. Am looking for 12" for surround cabnets and 18" or 24" sub woofers for a sub. As well as horns and the HF drivers for the horns. My goal is to build my own home versions of what theaters are using in there big rooms. Dual 12" woofers and a horn. And I want 18" sub minimum.
