Massive bass with the volume cranked up if boxed right u get 0 distortion and window popping hair raising bass for every day driving with ur mum n dad in the car u can have the bass control at your finger tips so u don’t break the olds hips and they will run cool all day. I’ve had a set for over 8 years and both are still pumping as hard as ever. From music like Cold chisel to songs like centerpeade and the best bass from AC/DC there is nothing I’ve put them thru that they don’t spit out perfect bass everyday running soundstream xxx mono block and a few lil tweaks the subs love there job and do it well. I can’t speak more highly of these subs and will never change as long as the keep pushing out as much sound and feel as they do. Buy them and you will not be disappointed they F...ing rock 🤙🏻

Not 1 thing maybe if your putting in more than 1 in a box the weight will need more than 1 person. But that’s instal nothing bad on the subs in any way. I’ll stand by and will always run a min of 2x 12” splx in a box in the boot and will be the guy with the grin from ear to ear 🖐🏻 5 stars and 1 more for being so damn good

Extremely hard bass, capable of hitting some of the lowest frequencies.

First off, this Sub is just flat out amazing. I used to have a Kicker CVR 12" on a 750.1 Kicker ampliier and I was ok with it, but I wanted more. So I stepped up and bought a Planet Audio 1900.1 amplifier with a 12" SPLX Soundstream subwoofer brand new. I built my own custom ported box to 33 hertz and installed it. I was kind of afriad to turn it up because I knew how loud it would be. I turned it on and, I nearly choked on my soda. This sub was pounding out so much bass in my single cab pickup truck, that it made a bunch of stuff in the garage fall off of the walls. This thing was about 5 times as loud as the Kicker setup I had. After the initial hit, I turned the bass knob off of low, and put it on high, and cranked it to 3/4 volume and I had to get out of the car, it was making my head hurt. This is one of the baddest subs I've owned yet, and will always keep this subwoofer. The magnet structure is truly amazing. It's a double stacked magnet, with the magnet weighing in at 192 ounces.(16 pounds) This sub is truly amazing, I've ne ver heard another single 12" sub setup sound like mine, it's flatout insane. I dB'ed it at half volume and it hit 145.7dB on the meter. If you can afford this sub, buy it and put 2000 watts on it, and it will shake the ground.
