Tyler U7?

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.

I have the 7Us in my 2nd system 22X23 room with 9ft ceilings - drive them with a Plinius 8200 MK2 -very good sounding speakers; are the D3s better, I'dask Ty he's a straight shooter and let you know if there's a significant difference or not

The 7U's sound really nice. I have had them in my system some time ago. Are you buying them used? Doesn't matter really because the 7U's are a very speaker. Personally I would buy the D3's if you are buying new.
