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.
Hello Audiolui,

I do not own the newest T7, I had the older Britania series.
These are the best subs on the market. Sound is outstanding.
Placement is too easy. Tell your friend that he is making a wise choice.

Happy Listening!
Thank you all for sharing. I will pass the message to my friend. I think the REL T7 will do fine. But I need to warn him about the sub bouncing (walking) around on tile floor.

I also heard that some subs do bounce (walk) around when driven hard on either tile or carpeted floor.
