Bought these for my theater room and they work amazing as center side speakers for 7.1.
Not that heavy and easy to hang. Very happy with the purchase.

Purchased these speakers to replace a pair of Mirage speakers I've had for 20 years. I cannot believe how much better the Definitive speakers sound. They have a much cleaner and crisp sound than what I was used to. I have been upgrading many of my components over the past year and this was a great addition.

Great sound and Quilty Speakers.
They are a little big to be used for surround sound speakers but still work great!

Good item. Actually, I ended up returning them because I found a similar set in my storage made by Polk Audio, OK...I admit,,,these are better. But I kept the Polk Audio since they were paid for. These were, however, better.

I have these as my rear speakers. They are full and throw a lot of sound. I only wish they have different mounting options.

Must have for your theater room or surround sound system. I paired these with two floors, Atmos uppers, and a matching center...it's unreal. Have Geek Squad install it, so they can tune it. It makes all the difference!

I bought a pair of Def Tech SR-9040s to add to my 7.1 surround sound. This is the best bang for the buck speakers I have purchased. Granted, they were on sale for $199 each which is an awesome deal. I highly recommend SR-9040s to anyone looking for budget speakers.

I was very excited about the speaker package i got... also had Geek Squad install. Fresno needs to get a studio room to test these out prior to install. I had to drive to Modesto just to hear them.

Id had my eye on this speaker for a while and finally pulled the trigger on a pair. So glad i did! These were so much stronger rears than my existing that it improved the overall sound of my ststem significantly. Would certainly recommend them!

They are in my family room and are small enough to not be noticed yet the sound is great. I especially like the dipole radiation of the sound. I would have liked to have gone to the larger of this series but the areas that the speakers were going into was not wide enough yet after I installed these I was amazed at how big the sound was. Highly recommended.

If you have been reading my other reviews this will be no different. The system that I had purchased includes these speakers and wouldn't have been the same without them.
Great sound, small and good looking just like the rest of the Definitive speakers in my theater room.
It's like being in the middle of the action in any movie.

I replaced my rear speakers with these even though they are probably better suited as side speakers. They blow the old speakers away. Fantastic sound! My Definitive Floor speakers finally have some decent companions.
