Reviews and Problems with Definitive Technology SC4000
Showing 1-10 of 24
Clean, deep bass. Don't skimp on calibration. Auto-off switch needed.

Summary: Great sounding but calibrating is slightly complex. First I set the LPF to 80 Hz to comfortably pair with my main channel's rated 60 Hz floor, then determined the phase at 90 is optimal for my setup. Determined this by setting a spectrum analyzer tone to 80 Hz, then found 90 degrees produces the greatest amplitude. (The theory here is to make sure the drivers between the sub and main channels are in phase over an overlapped frequency).
Summary: Bought this based upon other reviews. My old sub just couldn't cut it. Now, even playing at modest volume, my movie enjoyment is often interrupted by my wife complaining about the noise. Couldn't ask for a better subwoofer for the price. I don't think I will ever be able to push this sub to its limits. My room is 13x26 in the basement and I think my roof shakes. Nice.

Summary: I have been a fan of Definitive Technology for many years, and bought this when starting to build my home theatre room for the second time. It is small but powerful. I particularly like the fluted edges and the red LED beneath the cover. The night (wife) mode is excellent, and the remote is really useful for changing between music and movie settings.
Summary: I AM A MUSIC GUY - NOT A MOVIE GUY, so bear this in mind as you read my review. This was the third subwoofer I purchased for my living room system, and the third time was in fact a charm! This sub definitely produces the tight, crisp, musical bass I was looking for. My front speakers are Dynaudio Audience 42, rear speakers are Fluance AVBP2. I have no center speaker. The amp is a cheap Pioneer VSX-818V.
Summary: I just recently bought the def tech sc4000 I have two bipolar 8040 in the front and 8060 center speaker. The sub is good I thought it would be better from all the good reviews I read that's what pushed me to buy it. I have a fairly large living room and I barely notice the difference with the new sub I have it in 20v and if I push it more the sound does get muffled. I'm pleased with it don't get me wrong but for this price I was expecting something with a lot more boom.
Summary: This is an absolutely amazing subwoofer. This is only my second subwoofer purchase and it is replacing an M&K MX200 purchased in 1996. I had chosen the M&K for not just its power but its bass quality. Back then most subs were boomy and appealed predominately to the home theater market. While I use my system typically for home theater, I appreciate it most when listening to music so bass quality is first and foremost a concern. Back then the M&K was a standout.
Summary: I purchased this sub based on the reviews read here. As it would be just fine for a very small room, it's not at all good for a medium sized room. As volume went up so did the distortion. You could clearly hear it bottom out just when you need it most. Save your money and get a real sub for the same money. Any svs sub would be far better.
Remote parameter changes with a remote make this a winner

Summary: Bought the Super Cube 4000 to replace a Super Cube III (manual volume control failed & replacement low-level amp RMA underway). The remote makes all the difference - sitting at the normal listening location and changing the low pass filter, phase, volume (and mute), built-in EQ (4 choices) as well as the display on/off (visually see parameter settings).
It's small, and it sounds good, not great. (maybe best paired with smaller speakers)

Summary: Used with satellite speakers it will probably sound good, but it doesn't add much (and can even detract from) speakers with 6" or greater drivers. I was hoping that a dedicated woofer, designed to handle only a small part of the audio signal, combined with an internal amp optimized for that speaker would have given me better sound. First, I used it to save my large speakers from some of the overly cooked low-bass on movie soundtracks.
Summary: Was advised by a sound professional to purchase this, and glad I did. This sub is awesome! The sound is clean and natural. I love having the remote to be able to turn it down when my animals get nervous from the big thindering boom from cinema action. Great features,; great buy. Highly reccomend.
