[QUOTE="Mike Caldwell, post: 213513, member: 170"] Hello Greg. I think it's fair to say that not all small format 1"exit 1.5"ish voice coil compression drivers are created the same and there are a few that have some meat to them but not even the "meaty ones" can compare to a large or even a medium format 1.5 x 3 compression driver. In the case of my RCF 732 example they use a 700hz crossover in that box getting a lot of what matters in to the pattern control of the horn, and for everyone following along I know that horn patters do change with frequency but still! I was just looking up some info on speakers for a possible project and was kind surprised to find that the JBL SRX series with their 1.5 x 3 compression drivers are using a 1900hz crossover in many of those boxes both passive and active. I know they can do a lot of tricks in the DSP but 1900hz? Back to the original question.....for a 15 inch powered speaker look at the RCF ART 735, 1.5 x 3 high frequency driver. You can step it a notch to the RCF ART 745 that has a 2 x 4 high frequency driver. In the molded plastic box speaker market the RCF ART models are the only ones I know of that have large format compression drivers. I find myself using my 12 inch ART732's more than I thought I would, keep in mind I build 95% of the speakers I use. [/QUOTE]
