KRK RP10S Active Subwoofer

Feature:
Crossover from 50 to 130hz, suggested is 80. Minimum volume on the sub (-30db) is awfully loud. -60db would have been a better choice.

Quality:
The first one I purchased had a bad output, the crossover frequency was virtually unresponsive, and the volume knob distorted quickly. I took it back and exchanged for a new one, which corrected these malfunctions plus provided a much smoother sounding sub.

Value:
Don't know if there's a better cheap sub out there. I like it because it matches my monitors.

Desirability:
Subs have always been a "wow" item. It's huge and it thumps. I don't know how I've lived so long without it.

Sound:
This sub helps out the rp8's significantly in the low end. Bass is smooth and full, no boominess.

Ease of Use:
I'm inclined to think that those who have had issues with this sub are not setting it up correctly. There are a few keys to making this sub sound good. 1) Location: I prefer mine at floor level, in the center of my monitors. 2) Level Matching: sub's minimum volume is designed for a loud volume from your monitors. Turn your monitors up until you get a good mix between monitors and sub, then reduce your output volume from the signal source. 3) Sound transfer dampening: I folded up a blanket about 3 inches thick and set the sub on it. Drastically improved the sound.

Support:
Have never dealt.

Overall:
I was having a difficult time judging bass lines, toms, and kick in my mixes. This sub makes it a lot easier. I do a lot of casual listening as recording is merely a hobby of mine, and sub is very impressive for that also.

Feature:
Some of the best things about this is its SOLID and has different input/output jacks.

Quality:
built solid; no seams except the back where you could service the unit.

Value:
I think it's worth what you pay for.

Desirability:
It's a must have for any home project studio; along with any other monitoring system. No matter what the monitor speakers are, without the subwoofer, you'll find you'll be spending more time and resources remixing a final project without the sub.

Sound:
Very clean sub-woofer. Makes a big difference during mix downs for truth response in other players (cars, stereos, etc)

Ease of Use:
plug it in and go. Volume knob on the back of the unit to adjust level of bass (which is very helpful to help you determine where you need to be at when mixing).

Support:
n/a

Overall:
I use this in conjunction with the RP8's. I just got it a couple days ago, working on a project. Without it, I mixed a project using just the pair of RP8s. What I thought had sufficient bass ended up being way too much; even though the RP8s have a great response across the frequency range. I "installed" the subwoofer, mixed and burned a CD, found it alot closer; made a slight adjustment to the subwoofer volume, mixed and done it again; dead on. A DEFINITE MUST.
