Speaker System Unity

Each speaker within this system compliments its counterparts accurately and successfully. This home theater system doesn’t leave any gaps within the frequency range and produces accurate and natural voice matching from speaker to speaker. You don’t have to set the subwoofer’s crossover frequency high because the center speaker dips down to take over the mid-bass frequencies and leaves the subwoofer to do its diligence in the low frequency range. The satellite speakers produce clean and natural sounding highs and bring true surround sound experience to your home theater system.

Subwoofer Specs.

A powerful subwoofer is a pivotal piece to a quality home theater speaker setup. Not all speaker systems we reviewed carry a dedicated subwoofer, but the ProCinema 400's subwoofer brings the power of bottom-end tones to your home entertainment center.

The subwoofer uses an 8-inch down-firing driver that has a built-in 150-watt amplifier to drive the low tones when you are listening to music or watching movies. The custom down-firing port design lets you feel the rattle of the bass under your feet. And when extra bass response is needed, the ProSub 400 can handle up to 225 watts of peak power. Powerful subwoofers in home theater speaker systems are few and far between, so this Definitive Technology set sticks out among competing systems.

Center Speaker Specs.

This home theater speaker system comes with a designated center speaker. Not only does this further enhance your audio experience, but it is the best way to project amazing vocal sound all around the room, especially in very large home theaters.

Center speakers are perhaps the most important elements in your surround sound setup. Center speakers tend to handle up to 75 percent of the dialogue heard in movies. The center speaker ties the satellite speakers and subwoofer together for a cohesive and unified home theater experience.

The center speaker for the ProCinema 400 has a more dynamic frequency response than the satellite speakers. The 110Hz low frequency response helps to bridge the gap between the low tones of the subwoofer to the ultrasonic tones covered by the satellites.

Satellite Speaker Specs.

Satellite speakers bring cinema quality audio into your home. They give you the surround sound experience by expanding the soundstage from right in front of you to all around you. The ProCinema 400 comes with four satellite speakers that are small and light enough to be mounted to your wall.

This sound system has one of the best frequency ranges of all the home theater speaker systems we reviewed. The speakers cover 130Hz up to 30kHz. Though the human ear can only hear up to 20kHz, ultrasonic tones that exceed 20kHz add ambiance and texture to music and movies. The four satellite speakers have the frequency range capabilities to capture and produce these ultrasonic sounds and deliver soundtracks the way they were intended to be heard.

The satellite speakers have a decent sensitivity rating of 88dB. Speaker sensitivity is in direct correlation with a speaker’s ability to convert electricity into sound. Typically, the higher the sensitivity rating is, the better the speaker will perform. Though 88dB is not the highest sensitivity rating, it is among the top home theater speakers reviewed.

Help & Support

It is not easy to install this home theater speaker system on your own if you are an amateur. There are extra wires, cables and steps involved; it could be easy to get confused. Though the home theater speakers come with an installation guide, the instructions are not that easy to follow, especially if you are not familiar with surround sound speaker systems.

Definitive Technology does have a few good support options for you to rely on. There is a FAQs section with product-specific questions and answers listed on each product page. Email and telephone support is always available with very courteous and knowledgeable staff. You can also connect with support personnel on the Definitive Technology Facebook page. If you find out that your system isn’t working due to a defect, the ProCinema 400 has a five-year warranty, so it will be fixed or replaced without question.


The ProCinema 400 is a great home theater speaker set. It’s the best 5.1 home theater speaker setup we reviewed, with a great frequency range, sturdy speaker cones and a dedicated center speaker. You can position the speakers to optimize the sound in your room, whether it is a large gathering place or an intimate living room. Since Definitive Technology pays close attention to creating uniform sound from all the speakers, you can expect great sound quality from these home theater speakers.
