Bryston B60 with Totem Arros

Specs indicate Arro's are only rated down to 40Hz. You would need a sub, especially to fully appreciate classical.

Agree that the Arro’s are small for your room. Have you auditioned them yet?
Even if you listen at moderate levels, you will need to push the volume and even then you won’t get enough bass response. Arro's can sound lovely, but I think you'll miss out on low-end extension.
