With a pair of these you can connect four midrange woofers and two tweeters to a 2-channel amplifier, that’s awesome! And thanks to its compact size, it’s the perfect choice for the DIY SPL enthusiasts out there.With a crossover frequency of 5.000 Hz and a slope of 6 dB/octave for the midrange driver, you’ll enjoy a smooth transition between the midrange and tweeter frequencies.
