Excerpt: I have these speakers paired with the Def Tech CS8040HD center speaker, Def Tech SR8040BP surround speakers and the Def Tech PMON800BK rear surround speakers. The system is powered by a Pioneer Elite SC-71 receiver. Speakers do an amazing job reproducing he full spectrum of sound from the vocals through the entire mid range to the bass. In respect to home theater there is no distortion regardless of volume levels.
Summary: I bought a couple of these speakers for the front and a couple of bp-8040st for the rear and the center channel and also the triangle shapes for the rear rear surround (7.1 setup). These speakers will not distort. They just get crazy loud. So. after a while my cat decided to attack one of the speakers and tore a big hole in the fabric on the speaker (still works just looks ugly). So I emailed them to order a replacement mesh, with no description of the situation.
Summary: I bought these almost a year ago with the deal that was going on where you get the free surrounds & center speaker. I read a lot of rave reviews about them before I pulled the trigger. After almost a year and listening to many different types of music and watching movies I can say that these speakers are so overrated and hyped up it's incredible. They have NO midrange whatsoever! They are all treble and bass. Snare drums disappear with these speakers. They have no punch.
Summary: When I first heard these speakers in my Home Theatre room I was literally blown away! You can hear things you never knew existed in the original sound recording! These speakers have a built in sub woofer that you have to supply power to. You can adjust the amount of bass you want directly on the back of the speaker.
Summary: This is really a (so call) high end speaker. You can feel it on all aspects, from built to sound quality. As an other reviewer descried, I can not say enough about how good the sound is. It always give a full, balanced range no matter in what volume. Because of the naturally reproduction of the sound, you feel less loud in high volume, while sufficient base at low volume. I can enjoy listening at very low volume in a mid night without bothering others' sleep.
