I have one.It's a beautiful box but has cheap construction. I've never seen a standard 920 in person but I assume the "T" to be a lower quality build from what I've been able to gather. It's certainly cheaper quality than my 918. It has very good bass,even better than my 918 as I remember. The highs were compromised until I put a set of real tweeters in the box. They fit perfectly to the fake tweeters screw holes and were identical in size. Now it has sweet sounding highs! Though very rare,that price is criminal!
