Gibson KRK S12.4 S12 Generation 4 - Subwoofer de Estudio (12", 220 W)

Great sub love it

A perfect match to my KRK V4S4 with the crossover set at 80hz. My JBL LSR310 sub had problems keeping up with the V4S4 output, even at -3db. Turning the JBL up to match output caused it to bottom out on bass heavy movies. The S12.4 stays clean & makes the bass needed to blend with the V4S4 with headroom to spare. Combined they are a soundbar killer. I've never heard a $4k soundbar but I'm guessing that's the starting point to match SQ of my set up. I'm using a Geshelli J3 DAC with V7 Classic opamps & a Topping A70 Pro as the preamp.

I was first struck by how huge this thing is, it’s also very heavy. The build quality is great, I would imagine the magnet is a hulking thing, not sure what the cabinet is made of maybe abs plastic perhaps. Now this thing puts out bass you can feel, window rattling bass, oh so much bass! It is also well behaved, within a half hour or less of no signal and she’s in standby mode, not half a day like that garbage Klipsch sub that lasted barely over a year, or that Polk sub that was defective right out of the box! I would recommend this sub very highly, if you’re scared by the price, don’t be, it’s worth every penny, remember, you get what you pay for. Runs circles around my previous two subs.

Very nice, clean monitor bass. Solid design.

At first I got this because I'm petty and our neighbors like to play trash rap on a garbage Bluetooth speaker at 4 AM. Since they moved, I have come to truly appreciate the extra octave of low frequencies heard and felt by including this with my KRK8s. To maintain objectivity, I added a foot pedal to on/off the sub. The response is quite linear. The effect is impressive from low volumes all the way to SPL that would inspire my new neighbors to buy an even larger subwoofer than this.
