Before the Soundslabs, I had Quad2905 in my main listening room and had a Rythmik direct-servo Sub just to add a little rumble to the low end, i had the low pass crossover set to 44hz.
The Soundlabs (922) have much more bass than the Quads and after a listening session, I decided I didn’t have a need for the Sub.
Now the Quads are in my office and because the room is smaller, they have more bass and they are generally used for low level background near field listening, and I opted to sell the Sub.
