If you're talking about the one-piece Linnbrook with two 8-inch woofers, and the tweeter surrounded by the two 7-inch mid ranges on top, as opposed to the two piece monitor-on-top-of bass module (all same drivers but rear ported) I can make some comments. I have the two piece system. I would get the one piece system if I had a smaller room - the bass modules on the two-piece system are rear ported and so deep (in dimension) that the front of the speaker (and monitor) needs to end up being something like at least 6-8 feet from the back wall, otherwise the bass is very heavy.
That said, obviously I like these speakers because I own them. I actually have three monitors for front and the two big ones in the back for a surround system (for 5-channel I only play the 5 monitors).
Anyway, they are coherent but you need to get yourself about 7-8 feet away from them at least for good driver integration. So again, big room. They still sound good up close though, which is always the hall mark of a good speaker. Bass is not overpowering - if some makers sacrifice quality for 'boom,' Tyler goes the oppposite way. Bass quality is excellent, and with good recordings you will feel it hit your chest. The mid range and treble is really outstanding. And as mentioned before you can get away with cheaper electronics, though these will sing better and better the more you feed them with better stuff. As for build quality, assuming pure weight is a good factor in deciding speaker quality, see how many 150 lb speakers you can find out there for less than 10 grand... if you would like more specifics feel free to email me. I suppose I should mention that I am on Ty's home-demo list for peopple that want to listen before buying.
Thanks
