My dad's got a pair of 1972 La Scala's, and I'm gonna give 'em a little extra kick, by replacing the K-33-E subs with something better. (I already blew up 1 of the subs... they're good, but they just don't handle the sort of power I need... they really don't like having any more than about 200W RMS continually pumped into them... the tweeter/squaker can handle it, but the subs won't.) What should I use? I chucked in a JBL sub that I got out of a J-bin, but it's horrible. It rattles and clacks because it relies on having an open enclosure, unlike the K-33-E. (Oh, and I know Klipsch rate the La Scalas as capable of a maximum of 124dB, but they can do more... even when you're not driving them to bursting point) I've considered other speakers, but the La Scala enclosure is the best IMO. Lowest distortion. Any ideas? (oh, and in case you're interested, here in Melbourne, Australia, La Scala's retail for $9000 aussie dollars, brand new, so they're pretty rare here.)
