I am running the Troels Gravsen TL2 as front speakers and the Alpairs as rears both off the Dave.
DIY speakers can have some great savings money-wise and still be mighty impressive to listen to, the TL2 can be built in different versions with a choice of super tweeter, I got some of the last GRT145 super tweeters but unfortunately, the chap who made them is Russian and production has now stopped.
As Troels says in his write-up of the TL2 you can sit 4 people on a sofa in front of them and everyone gets a solid stereo image...and I can confirm it's true.
The sound from the compression driver and 10" midrange driver creates solid imaging with a clarity I have never had before all this is backed up with the BMS 18" subs which I was a little skeptical about needing at first but now couldn't be without them.
