Definitive Technology - ProSub 800 8" 300-Watt Powered Subwoofer - Black

I recently added this subwoofer to my theater sound system. I now have two subs. I bought this because of my previous experience with Definitive. I did not listen to it before I bought. I pulled the trigger quickly because Amazon had it on sale for about 50% off and Best Buy price matches. Normally I would go into a store and listen (feel). Anyway, glad I pulled the trigger. This thumps! It is not as hard hitting as my JBL L8400p, but at 50% of the cost before the extra 50% I got off, I wouldn't expect it to. More "boomy" than the JBL so it compliments the other sub well. I'm extremely happy with this purchase.

Pricey… replacing an older Def tech powered sub that died after about 5-6 years, power supply gave out. Hopefully this one last as long or longer. Needed something with a small footprint, this fit the bill and pairs nicely with our older Def Tech high/mid range speakers that are still kicking.

Took some adjusting and settings to get it work well with my other sub but after a few days I really started to love the sub. Does not work well on a hardwood flooring without it sitting on some carpet. The passive bottom firing radiator will make the sub dance all over easily. Especially with scenes in the movie "Interstellar" Its well built and I kinda like the side mounted volume control but I think it would be better if it was top mounted. Its exceptional tighter than my 10" ported sub its paired with when it comes to lower end bass

This DefTech ProSub 800 is a good subwoofer although it did not fit my application. I wanted an 8" sub that would be used in the LR to fill in the bottom end to my ceiling speakers. This is not a HT room and is mostly used for listening to music while entertaining or working around the house. In order to really get the bottom end, I had to turn up the volume and the sub bounced across my wood floor. Don't get me wrong, this sub is really great musically...it just did not give me what I was looking for.

Part of the upgrade to my TV room in my basement. Decided to upgrade to the Sony Projector 4k and then needed to upgrade my Subwoffer.

I have an old 7 channel speaker set and the subwoofer just died. The challenge that I had was to find something that fit in the limited space we had as the old one was fairly small. This unit was perfectly sized and reasonably priced so it fit my immediate requirements. Once I got it home and connected, I was just blown away. The bass is rich and deep for music and absolutely explosive for movies. Our old unit sounded ok but tended to rattle things a bit so it could sound messy at higher volumes. This new unit is just smooth and sounds amazing. I highly recommend this unit.

I had my subwoofer go out, and I had purchased an exact duplicate of this sub earlier because it was on sale. Then I would have two. Then I needed to replace my M&K sub, so I purchased this one because of my experience with the other like this. And again on sale. Very happy with them.

My large sub had shorted out from all the dust that collected on it while in storage. I wanted a sub in my apartment so I looked for a good, smaller, cheaper sub. And after watching the hobbit trilogy with it I would absolutly recommend it to anyone who wants solid bass for there home theater system.
