REL T7 Subwoofer

Anyone who owns this sub,
Is there any reliability issue with this sub? Comment on sound quality and ease of use is welcome. My friend who just started this hobby is thinking about this sub. Thanks.
But do some research...there is plenty of reliability issues reported with REL, I had several myself.
Audiolui, I own a REL T5, not a T7 but ....
This is IMO a great little sub. Superbly fast and able to go down easily into the low 30Hz's. The REL T7 should be equally as adept and therefore I would highly recommend it.
BTW, no reliability issues whatsoever.
