Perfect match for my q750'SI set out to buy a five speaker set of main speakers with "matched drivers". I decided on the Q650C, Q750 mains and Q50A Atmos toppers. After owning them for a couple of months I really like how they sound with my Marantz gear. The Q650C could be the highlight of the package. It is clear, open and dynamic. I think it is very obvious to hear that the Q650C and Q750's have identical or extremely similar drivers. The sound blends to form a huge soundstage with very precise imaging.
I know it is possible to spend far more on speakers but I could not be happier with the results.Posted on

Q650 Loudspeaker Review - Hi-Def Digest |
"...the two 6.5" drivers and one 6.5" ABR deliver clear vocals and distinct imaging across the front soundstage. In swapping between the Q650c, old iQ6c, and a $200 center channel from another brand, returning to the Q650c is a delight thanks to its accuracy. You can even set them to "large" in your AVR's speaker settings with a 60Hz crossover and come away with no distortion. That's impressive. In an age where most people (understandably) go for a simple sound bar system, three cheers for a nice, beefy center channel that can keep up with its badass tower brothers.” |

Q650c 5.1 Speaker Review |
"These speakers have little trouble blistering through the trigger-happy car chase of the opening scenes - they use every ounce of their muscle to pin us back into the sofa.” |
