Definitive Technology ProSub 1000: it will make you dance

Definitive Technology ProSub 1000 review & specs

ProSub 1000 produces great sound/bass when watching movies or playing video games on Xbox or anything else. It works so well at this, that sometimes you may not pick up on the subtle sounds that are actually coming from the woofer that set make the scenes much more realistic. Music played over sound system sounds absolutely fantastic at all volume levels. These speakers and sub will put out more volume than a person can bear to listen too. Definitive Technology ProSub 1000 review has even more useful details and you’re welcome to read about it.

The design includes one 10-inch front-firing woofer pressure coupled to one 10-inch down-firing low bass radiator. The cabinet employs unitized construction where all panels are joined together into one solid structure to minimize vibration. The cabinet walls are made from high-density mediate fused together by polymer adhesives, and the bulky front and rear baffles feature extensive internal bracing.

The subwoofer has an LFE input as well as high-level inputs for connecting to the acoustic outputs of an amplifier or receiver. There are also filtered acoustic outputs for connecting satellite speakers. Two-stage input filter allows you to customize the sound of the subwoofer for precise matching with any basic acoustics.


Very solid sub, able to produce vast low-end extension down to 18 or 19 Hz but this is more pressure waves that are undetectable to all but neighbors and tooth fillings. Tail off in volume happens in the low 25 Hz range but few, if any, sources demand prolonged low-end response. Despite the ProSub 1000 specs my only knock of this sub is the auto-on feature which lags in low signal response them turns on suddenly when a signal of significant wattage comes into the sub and your face gets ripped off. Tight, precise, and will provide that sonic vibration associated with theater experience.

Performance & Sound quality

The sub-woofer itself has a volume control on the side so you can adjust how much bass you want to get for the given media you are watching or listening to. It seems different music, movies, and games all have their soundtracks adjusted differently. Some are low with very little bass, some have a ton of bass that overpowers the other sounds. This separate volume control on the side of the sub allows you to quickly set the woofer to produce the volume level appropriate to whatever film or music you can listen to without having to go adjusting things in the receiver menu.

The amplifier in the subwoofer has output stages on discrete MOSFET transistors, is made using the patented technology Infinite Power Source, and develops up to 300 watts. The amplifier circuit is mounted on printed circuit boards of “military” quality, using precision resistors and capacitors. ProSub 1000 uses a double protection system to prevent damage to it in the event of any abnormal situations.


There are two ways to adjust the ProSub 1000 setup sub with speakers. Running speakers through sub and sub back to receiver gives sub full bass but the speakers loss some of the detail and delicate notes. Not harsh sounding but running speakers directly to the receiver and sub on LFE seems to sound better and set the crossover at receiver.

Speaking of Definitive Technology ProSub 1000 settings I think this is a great sounding and versatile sub. Can you find better subs? Yes, but they also cost more. Also, a sealed sub is great for music, not movies and a lot of ported subs are good for movies and get lost with music. For the money, being able to use with movies/music and easy placement and blending of speakers I highly recommend the product.

To eliminate the danger of coloring the sound at a high listening volume, the sub body has an almost monolithic construction, with a very tight connection of the panels using a special polymer adhesive. The front and rear walls have an increased thickness, and the ProSub 1000 case is also reinforced with numerous internal ties.


Without a great sub, a home theatre is not complete.ProSub 1000 does everything I could want. It goes extremely deep, it shakes walls, it punches with tight, powerful bass, and it has incredible musicality. It's equally awesome during an action movie, a rock cd, and a classical piece. Great build quality and fair price. This sub is a great all-around sub. Good with music and great with movies.
