Definitive Technology DM90 Speakers are amazing sounding height speakers. These are perfect for home theaters that don’t have the wall space or the capability to run wires in the wall to mount true height speakers. The DM90 blend in seamlessly with the Definitive Technology DM80 and DM70 speakers. These speakers sound amazing when playing Dolby Atmos soundtracks. The sound bounces off my 10-foot ceiling with ease. The Frequency response range (81 Hz–30 kHz ) and sensitivity (90dB) is amazing for such little speakers. I have my home theater setup in a great room which is not ideal location due to a lot of open area, but these speakers still are able to fill the area. I have been a fan/owner of Definitive Technology speakers for a while because of their sound quality and their customer support. I called their customer service twice each time I received quick and friendly responses. The only cons to these DM90s are the fabric cannot be removed , so I must vacuum my speaker every so often, and the DM90 makes my DM70 speaker even taller, which could be an issue for some side viewing angels if place near the tv of screen.

These fit the DM70 that I also own and the DM80 which, if you can spring for the couple extra dollars, go 80. Paired up with the DM70s, well, there is seriously nothing I could add that hasn't been said better by someone else. -I'm new to the brand but a fast friend. I went all in pretty quickly. I haven't had fun updating a major component or system in my home in a long time. It is always a DRAG to have to update as things age. Not with this brand or product. It has been a journey, I will say that, but I have enjoyed it. Once I have finished I will come back and put some pictures up.
