Do you have a speaker that’s not a big name maker but punches above its weight? Why?

I am fond of two speaker manufacturers that sold direct on the West coast, Speakerlab and Roger's Sound Labs. The Speakerlab K-horns and model 7s are both high sensitivity speakers, ditto the RSL Nevada and 6600H. RSL also had some models patterned on the JBL L100.

Another vote for Usher out of Taiwan. Beautiful speakers. They have some great entry level models like the S520, BE-718, and the Mini Dancer series. They also have many higher tier designs that compete with some of the best out there. The only downside is they can be hard to find depending no where you live. Especially the higher models. I'm considering grabbing their newish 50th Anniversary model, those look particularly enticing.

I'll also mention Lawrance Audio. They were a little more popular about 10 years ago, I never hear of them now although they appear to still be around. I have the Mandolins and the Violin SE, both sounds very nice and also unique looking. 

I'll never part with my Shahinian Obelisks, I've yet to encounter a speaker I like as much.
