PLUS: good sound and performance, good dynamics, excellent price. MINUS: sound is good, not perfect. I would have appreciated more crystalline highs, better spatial presentation and lower bass excursion. The eighteen would certainly tolerate a start from 50 Hz. The lower bands are nicely reproduced only at higher dynamic levels. Dimensions. It could be even smaller. The performance of 300 + 300 + 600 is already managed by the Germans even with half the dimensions. But for the price - excellent.
