I have a Mystere ia21 INTEGRATED tube amp running KT120 tubes [no line level out] and Martin Logan Theos in gloss black. I am using the 4-ohm taps. I am looking to add a sub [Theos is lacking in bass]. My room is about 200 SF and has wall-to-wall carpet. This is for a 2-channel system only. I have a separate HT system. I have two requirements for sub:
1. Must be gloss black to match Theos.
2. Must have high level inputs [connect to amp outputs] since I have no line level outputs on amp.
I was thinking of the REL T/7i as it meets both of my above requirements, but there is a lot of negative opinions on REL on this website. So realistically, what are my options?
Thanks in advance, and everybody please remain safe!
