[QUOTE="Bennett Prescott, post: 58554, member: 4"] Re: Voicing/tuning a 3-way home brew speaker cab John, The first 90% of tuning is the easiest, as you can mostly see and hear the problems quickly and correct them quickly. The remaining 10% is the stuff that isn't clear on the measurement, and maybe you can only tame but not fix with EQ, and getting the bandpasses to line up off axis. I always start with raw driver response to take a look at what I've got, as well as sensitivity differences between different passbands. Seeing how well behaved the raw driver is gives me an idea of what crossover points I can use, and whether I'm going to have to really pack them in or whether I've got some breathing room. Then I go for the nastiest out of band problems with EQ. I normally use BW or BS 12 or 18dB/octave slopes. Maybe steeper for the sub low pass. I have never used LR48 except as a demonstration of how to make subs sound "slow". I only use LR24 if I need to work in a tight frequency space with rough measurements. [/QUOTE]
