After a 10 minute read I believed the hype of the DBA and purchased four of the 10''Morrel titaniums and two sa-1000 amps, only needed one amp I found out later. Built some plywood boxes and these things have transformed my system into something I never dreamed possible. These b&w 802 series 3 were garbage speakers for anything just about, not so now. I don't even have the subs completely dialed in, it doesn't matter.
The only thing you need to know is how soon can you get yours started! You don't need fancy mics and other crap like that to measure anything, has anyone tried a swarm and not like it and removed it?
