So recently I bought a pair of Tyler acoustics new model the U2. Very large cabinet, I don't know if you can call it a bookshelf speaker

Looks good, well built. They use SB acoustics drivers and good quality crossover parts.
The sound is neutral and smooth. Enough clarity without any harness. I think those speakers will be very sensitive to the electronics they are paring with. The bass is present without being overwhelmed and extension is also very good. They are easy to placement, thanks to the front ported design.
Overall a very well made and sounding speaker
