Back in February 2017 I purchased the scan-speak b741 kit from Madisound. I substituted the single 4 ohm midrange for a pair of 8 ohm of same model. I inserted these into my Dunlavy sc-iv cabinets. I also removed the foam rubber and wiring and replaced with Supra 13 awg speaker wire and wool damping. The woofers and midrange needed spacer plates which I fabricated from round 1/16" steel plates. The tweeter just needed a new notch in the cabinet. I also changed out the Clarity Cap ESA 6.8 uF and 22 uF caps for Clarity Cap CMR's in the tweeter crossover. Since the crossovers are much larger than what they replaced I decided to mount them externally. I have a pair of F113's subs for the lower frequencies. The detail is just incredible. Listening volumes have gone way down. My listening choices have moved more into classical and jazz because of the improvement in hearing everything. My advice to royboy 11532 is if you have the skill level the Scan-speak b741 kit is a pretty good set-up.
Infinity cs 3009
Brand new here. Does anyone have any knowledge on cabinet specifications or have technical input for Infinity cs 3009? I am thinking about actually trying to build a pair, or at least something comparable or better than these. Heard us at years ago and loved them and now I cannot seem to find any to purchase. Any help or input would be appreciated.
