Hey, lets resurrect an old thread! Not sure how I missed this thread ( especially since I commented in it ) in my searches for info on the B&C 14CXN88s. I've got one in the shop right now ( thanks Bennett ) running a little monitor wedge shoot out with my existing wedges ( I have four different brands and models in stock, time to get rational here ). I've installed the 1488 in an existing single 15 wedge on an adaptor board mainly to evaluate the mid to high performance and coverage pattern. LF performance will be addressed when I design some boxes, compared to the performance in the voice range thats a second tier consideration . Doing a round robin of filter tweeks, Smaart TF curves and listening with a variety of tracks. So far the 1488 sounds quite good. Certainly better than two out of the four wedges I'm testing against and on a par with the other two. Testing has been with a pair of Lab Gruppen IPD amps using the internal DSP all with LR 24db / oct filters. As part of my testing I've also tried some second and third order filters trying to emulate possible passive crossovers as having at least a few wedges with internal crossovers would be handy. My tests with the lower order filters thus far have not turned out nearly as well. Use, would you be interested in sharing what sort of box and passive filter design you went with?
