I started with the Classic MANY years ago. When that blew up, I went with the L1M2. I still have it, but it's overkill for many of my gigs right now. I bought a pair of S1s and really like them and they can cover my gigs plus some, but I miss the low-end thump (1 acoustic guitar, 2 vocals).
I just bought a Compact from a friend and it just doesn't seem very loud to me. I'd likely never use it alone, so I hooked up my T1 mixer and it was better, but still lacking in volume to me. It even seemed like it might not be as loud as a single S1.
Am I imagining things?
