Good BEEFY construction and the sensitivity is good too. There’s no humming when turned to 0db (I’m using bargain chinese rcas for a small project). I’ve seen reviews with the hummin problem but that sounds like a poorly installed ground. This item is so good I’m also installing it with my 2,000 watts amp in my big project
I should have listened to the reviews and not bothered with this. They were right, this does not work the way its supposed to. It still lets higher frequencies through. Turning down the frquencey knob just lowers the over all volume level and the gain knob does the same thing. You get one star when your product dont even work.
Hard-to-find dividing network for outboard woofer use. Controls (gain and turnover frequency) allow welcome flexibility in matching woofer output to mid-range and high range output sensitivity. Works exactly as intended without a hitch!
