![]() ![]() ![]() I mate them to my JBL4320 quad stacks using active cross-over at 200Hz, tri-amping to the quad JBL and the SP-200. Some internet sources say it's 100dB SPL efficient, while the original pamphlet says 95dB. Yikesssssssssssssssssss!Again long story short, I ordered some new mkp caps and voila!The cap update and de-oxit clean job made the SP-200 sound very very very crystal clear with rich mid bass arnd 200Hz, and a very lucent mids probably thanks to the two 5' squawkers serving up to 5KHz. ![]() This pair sounded awful with muddled sound like there was no mids no highs.But I opened the back baffle and found easily, one non-polar 4 ufd Rubycon axial grey cap exploded on one side, giving an open circuit to the tweeter, and all the other 3 caps were all too far off stated capacitances, like the other 4 ufd changed to 1.2ufd, an 8 ufd to 2.8, and a 24 ufd to 8 ufd. ![]()
