Tekton Lore-S

They are fantastic. Definitely give them a good break in period. I honestly didnt like them out of the box. After a few months i love them. I enjoy the clarity, the punch with bass and drums, and you can really hear alternative type guitar riffs in a totally new way. Velocity girl, cure, new order, even d guetta and armin van burren (the former has a pretty bad sound engineer) sound better, with more details in the mids, beyond the usual low thump and highs. I have used vintage jbl century l 100s, good paradigm bookshelves, kef, and have lots of hours listening to big expensive b&w on a friends system. Tektons are more versatile, have better mids, seem to reveal more detail and have a nice bass and low mid that the others didn't have. Plus, more options on amps with the high efficiency. Also, if you listen at all to vocals, classic, chamber or jazz, they re much better than other speakers I have heard in the price range. I can't think of a negative with them, other than the size - pretty big, and I wish they had a grille on the large transducers.

I just bought the signature 15 but we had a problem with the charger so a new charger is in the mail now. I had a great six hours with the battery and really liked it, it certainly had plenty of power for the tektons, lots of bass, nice mid detail, and could go much louder than I could want, and I have a very large high ceiling room. So, in terms of power, it's fine. I'll post more on the sound when I am able to give it a real listen, and probably the amp needs some break in as well. One thing I did notice is the system brings out a lot of detail and the difference between sources and recordings was pretty significant. Somehow, i think that's normal for a good system, this is my first approach to a high end system.

What amp are you using and what kind of room? 

I think you would definitely benefit from a sub. I did with my setup.  Try to get one with adjustable crossover AND volume control so you can dial it in for your room.  Then experiment with using the sub bypass to your speakers (amp to sub then to speakers) and sub outs from the amp direct to the sub if you have it. one may work better for this setup. I would go with 14 inch or more on the sub - don't skimp on size. Keep us posted.
