There is some sort of strange ju-ju going on with this little combo. Somehow, the 12" Travis Toy Eminence loudspeaker and the Quilter cabinet have combined to form a whole that is bigger than the sum of its parts, producing a surprisingly authoritative bass response that belies the small cabinet size.
Taking full advantage of Thomann's excellent returns policy, I have been able to conduct a thorough A/B test between this Quilter Travis Toy 12 Combo and the newly released Quilter Travis Toy 15 Combo.
Having used a 15" Black Widow equipped Peavey Nashville 400 for twenty years, I was certain that anything smaller than a 15" loudspeaker would sound disappointingly 'small'. But this 12" equipped combo compares very well with the 15" NV400 and actually sounds bigger than the Quilter Travis Toy 15 Combo! The treble response of this 12"cab is also less brittle than the TT-15.
12" loudspeakers tend to be more directional, with a narrower beam of sound than 15's, so this TT-12 combo is not as 'wide' sounding as the Peavey NV400, but the complete absence of mains hum or buzz from the reverb, plus 11kg vs 30kg make for compelling reasons to turn a deaf ear to that characteristic.
