The new cabs sound superb. Like the Eden cabs, they really move alot of air. I was worried that the lack of weight might lighten the sound but that's not the case. They give a really clear tone with plenty of articulation right down to the low 'B' with warm, round tones, and boy are they loud! I now have 2 very subdued looking guitarists;-) A bonus is that the 2 cabs together weigh less than my old trace elliot 4x10 combo.
