Definitive Technology has done it again with DM70s! These towers are just as awesome as stated in the Audioholics review - https://www.audioholics.com/tower-speaker-reviews/def-tech-dymension-dm70-dm20/#toc-h2-3. I consider myself to be an advanced intermediate level Home Theater enthusiast and these speakers deliver on all levels, bass, mids, and highs. Prior to upgrading to the DM70s I owned the BP8020s, great speakers but comparing them to the DM70s is an apples and oranges comparison. The build quality has been greatly improved. The lack of LFE input isn’t missed and is an enhancement because this design approach opens the door to using 4 DM70s or more in a system with full-range audio at all channels! They definitely hit deep as u can see from my MultEQ-X measurements, without applying my room target curve these speakers play down in the 20Hz range. These speakers can easily be utilized without a dedicated sub but adding one definitely will take your system to the next level. I recommend 2 subs if you have the space to maintain balance. The highs are very articulate but not overly bright and the height of the mid/highs module is optimal for listening in a seated position. If you are searching for your next set of towers look no further, you will not be disappointed with this purchase.

Definitive Technology speakers are always worth their weight in value and quality, and boy are they heavy. Last set carried me for 12 years and that was pushing them hard and constant. I had concerns switching to a newer different model but all that went away once they arrived. The design is much different then my original ones but i can perch my atmos speakers right on top without having to upgrade just yet. Quality, quality, quality. Love em.

wow what a big upgrade from my bp8060 & bp9060 speakers. The DM70s sound quality are amazing. I have the DM70 paired with def tech center speaker DM30 and Marantz cinema 40 and Emotiva xpa-3. I'm still breaking in the DM70s and I'm sure they will sound better over time.
