Have a new vox ac 30 s1 , bought this speaker for an isobox project (6 to 7 sheets of 120cm x 60 cm 18mm mdf , lots of rock wool lots of screws ,glue hinges etc , attenuates very well, you can play up full and its not too loud , bass make a bit of rumble) and it has worked out a treat . Have it miked with a sm57, seinheisser mk4 and it sounds amazing in my DAW ,Reaper, Really warm.compressed tube saturation , tames the highs on the ac 30 just right , and no boxiness from the iso cab, great amp and speaker combo.
