My neighbour runs wide-bands over Ripol subs. Originally he had the same Tang-Bands. They are very nice! Good choice. He moved on to Lii Songs. And then, as in this picture to Lowthers. Now he has EMSpeaker electromagnets. I always loved the Tang Bands myself though.
PS: seems no pictures allowed here that are not url-based. Anyway, can provide more info somehow separately if wanted.
