"... and didn't look back" Wow. There's a statement.
To be sure, the JRs are overachievers. Mine have sounded their best ever just recently with some system changes. There's no getting around their res, detail, and coherency, despite twin cabs... and getting the type of bass they put out from such small drivers is fairly remarkable.
That said, and to substantiate my card carrying certifiable condition, I've been looking online, naturally, at Heperion, Proac, and tons of others, litterally. With no outlets for demo-ing, sensitivity and load were key for me. Along with some greater ease of operation, and hook ups.
The VSA that made sense on paper was the DB99 OR 100, the admission fee is beyond me for sure... but it seemed appropriate for use with ANY amp (s) regardless the power output. I didn't care much for having to vaccumm them too much either.
