Hi Davey, last night we were running TO's Splawn through an open back Avatar cab with 2 Eminence Tonespotters and got a great sound. Having said that, my cab for the Mini-Mat has a heritage G12M in it, but that is because the Mini-Mat likes the 20w speaker. I tried lots of other ones at Matamp and the G12M was best (but the heritage not the regular one). Jensen's are made in Italy so you should be able to get them in Europe too. Some of them sound very good (Matamp had a couple in demo cabs).
Happy New Year
