I A/B/C'd the Thiele, widebody ported and recto 2x12, all with V30. All sound great. I used both a Mini Recto and V:25.
All sounded clear across the frequency range. The 2x12 had the most low-end, but the widebody was almost indistinguishable from the 2x12. The Thiele had noticeably less low-end, which is why I chose the widebody.
NOTE: I had all 3 on the floor next to each other. Coupling to the floor is critical.
I have played through the Thiele several times, and it sounds great, really tight and pretty big. If you want more of a tight metal sound, it is probably great. I wanted as much low-end as I could get. I was trying to get the sound of a 4x12 in a small, portable setup.
The Thiele is also a lot smaller than the widebody, which is a nice feature. I have thought a lot about getting two Thieles due to the size, but I wound up ordering another widebody. The widebody is portable enough, and no compromise for me.
