I like the REL. Blends great with my harbeths and I would think it would also work well with your Spendors. Taps off your speaker outputs on your amp and you run your speakers full range.
Match subwoofer to Spendor S3/5?
Bought some Spendor S3/5 unheard but aware of limitations on bottom end and dynamics. Speaker is great for mid-range on acoustic jazz, female vocals,similar but curious if anyone has matched sub to it and what the impact is? Does it now work for rock, electric jazz, more dynamic stuff?
