O.K., some speaker talk..
Mean Green - I tried, not a success to my ears. Cone cry, even driven by a 22W Deluxe Reverb type of amplifier. It was also lacking treble and detail.
The guy was honest to deal with though, for me. I returned the speaker and he refunded me. If he could perfect the speaker it might be decent.
Recent speaker success for me boils down to what can sound loud and clean, is reasonably efficient, and has no cone cry, and is not harsh. I have, in a way, given up on new production JBL search. Loud, clean, not harsh and it is good enough for me with appropriate tone settings on amp, guitar and effects.
1) Eminence EM12N - Kind of a NEO magnet EVM 12L, sort of. Loud, clean, and light weight (because of NEO magnet)
2) Jensen Raptor - Not sure what this is a take on, but it sounds good. Clean, and loud, and nice overall tone. has high end detail, but not ice picky or harsh.
3) Eminence Wheelhouse - Kind of an EV 12L with Cannabis Rex (hemp) speaker cone, and NEO magnet. Nice, loud, clean, efficient, light weight.
I tried Tone Tubby Purple Haze, and Winterland when they first came out. Terrible cone cry. And this was even with the speaker on the lab test bench (not in a cab), a 22W amplifier could easily make the speaker exhibit cone cried badly, and I also tested them with two other amplifier to make sure it wasn't the amplifier causing the trouble. Total fail..big disappointment because they sounded good. I have not seen other reports of the thin cone tone tubbies having cone cry, so, I tent to think it's because they had not yet dialed-in the manufacturing process yet.
Weber California: I tried the Ceramic magnet version, with paper dust cap, and with large screen dust cap also. I never tried the aluminum dustcap. It wasn't a bad speaker, but I never bonded with it. Interestingly, the large screen dustcap sounded more bright and lively than the paper dustcap version (contrary to verbiage on Weber website).
Weber Neo: Not sure if they make it anymore. Didn't bond with it. Nothing bad to say about it, but nothing great to say about it. Seemed noticeably inefficient compared to JBL D120F (K120). It had a kind of harshness to it to my ear.
