Hi guys,
as the thread is alive again, I am contributing

I purchased 2 months ago a pair of Scott 186-B, I like them a lot, and here is what I can say :
3-way design, 1 10" woofer, a mid and a dome-tweeter.
Don't know how the cross-over is made, but there are two switches that allow fine tuning of the mid and the tweeter, 3 positions for each : neutral, -3dB, -6dB.
And believe me, that works and is very useful according to the room and the type of music I listen to.
My feeling about them :
Very well built, heavy, solid, beautiful but sober vintage look.
Mellow sound, correct tonal balance, good versatility (I listen to metal, electro, old rock, pop, reggae, instrumental and everything sounds fine).
Of course, I don't say they are incredible but we are very far from cheap plastic crap and if you can get a pair for $50, it's a good deal. I use them as my main and only switch to my small beloved Axiom m3Ti for hard-rock listening as those have a slight lack of medium (2-way with no crossover, fantastic built and sound) which suits perfectly that kind of music.
