Tyler U7?

I believe the model is 7U - not that it matters. But look at what is available in the threads here on the Linbrook Monitor, which is the same thing, except the 7U extends the cabinet to the floor. Perhaps more bass with the 7U with the greater cabinet volume; if the crossovers are any different, you'd probably have to ask Ty himself at the company. But otherwise, they have the same drivers and such. I have not seen much on the 7U's either, but there is a lot on the monitor, and that should get you pretty close.

The 7U's do not have the same drivers as the Linbrook monitors. The 7U's use the Scanspeak Revelator tweeter while the Linbrooks use the Seas Millenium. They both use two of the Seas 7" midbass drivers. I am not sure when they were first produced, but they were current until the Decade line came out. The newer production models had the grills attached with magnets while the older ones were held on with velcro dots. They were a slim floorstander that sounded pretty decent and had bass down to about 40 hz or so. They were front ported and should work well in a smallish to medium sized room.

Why even mess with the old when Tyler has a 20 day return policy on a new pair. Tyler had some very good help and ears when designing the new line. I would call Ty and talk to him about the differences. He is very straight forward.

Go for the D3's.
