Looking for the best bang for my buck in terms of Subs. Thinking about buying 2 SRX828P's Wondering if anyone has had any experience with these? They claim they hit 141db spec's are pretty good. Better options for similar price out there? Connivence and size are not too big of an issue. I'll be hitting them fairly hard with EDM style shows, need to keep up with 4 SRX815P tops.
