Hi to everyone.

I just recently purchased and my first receiver, an Onkyo 818 and had Def Tech SM55 pair for some time. Those are now replaced with a pair of CB-170.

I do feel, the passive radiators from SM 55 was good in terms of bass, but i am liking the CB-170 better for overall performance. The mid and high are clean with CBM-170.

I hope to add the remaining 3.1 speaker system with Sierras, and i am speculating which one would suit my apartment and ears!.
