Review on Enhance Your Audio System with Planet Audio EC10B 2-Way Electronic Crossover and Subwoofer Control by Christopher Gotcher

This is a great crossover for the price and the only crossover I have found that has the frequency and slope adjustments I need . With a 24/dB low-pass filter from 250Hz to 32Hz and bass boost from 0 to +12dB to 25Hz, you won't find another Xover in this price range with this kind of flexibility. I only use this crossover for my sub channel so I can't comment on the front/back output. The EC20B, in combination with my amp's low-pass filter and subsonic filter, allows me to get the precise slope I need for excellent sound quality in almost any application. Crossovers at 2 and even 3 times the price often have no frequency range or offer the same slope. I have used the EC20B with four 15" in an SPL setup and again in an SQ setup with two Alpine SWR1024ds. Both times this transition allowed me to get the right answer. Initially I was skeptical about the brand/price, but now the EC20B is a key component in my setup.
