Used in conjunction with a TRAVELER 102P 8 Ohms and a TTE501 head, the set is ultra versatile, with deep bass, no weakness in the highs, for me it's an ideal configuration. As for the speaker cabinet itself, nothing to complain about, MARKBASS has struck hard again. Very good quality both in terms of manufacturing and sound. The small adjustable tweeter does its job very well. From smooth tuning to big, sharp sound, everything is possible and the cabinet is self-sufficient. If you add to that its fairly light weight (barely 17kg) which will please fragile backs, its comfortable handles, its small size, and its relatively affordable price, this little 15'' is made for you. Highly recommended!!!
