Pregnant MBS112 team combo, which I use for 1 ½ years.
Small, lightweight, strong (the metal body, like the grille).
The 12 "is an interesting alternative, between the size of its 15" and accuracy of 10 ". A good compromise if you do not want or can not invest or lugging a sytème more complete.
Be careful however to choose the Amp: I think this forum does not accept more than 100W (150W can be the site of GK is not available at the moment so I am not able to specify. ..).
This limit can be puisssance rédibitoire for a lot of bass.
Very good reproduction of the entire spectrum with a surprisingly rich low despite its size and very accurate (that is one of the reference speakers for bass, an instrument could not be more generous and down and even sub).
The sound is rather like: modern and precise but with a real personality. To my taste all that much going on SWR (which are in excess in regard to the modern type) and less bland than Hartke.
Finally, great value for money. If I return to my comparison with SWR, both on the high end I think I have a low SWR, but when you see what they do in the same price range (Workingman series), I give without hesitation GK winner.
