Wrote the following about QSC KW181A active subwoofer

Wat een mooie en harde bass komt er uit dit ding alles klinkt super strak en zuiver ik heb hem nu op me slaapkamer staan en het is gewoon het eng om dit ding vol te laten blazen omdat me lampen al kapot getrilt zijn en zelfs de grond en alles erbij 2 verdiepingen lager nog trilt.

als deze subwoofer op vol volume staat wat in de winkel niet kan natuurlijk zul je horen en voelen dat alles gewoon zuiver en strak blijft en toch voel je het hard op je borst
hij krijgt het zelfs voor elkaar om een reciever van 10 kilo weg te laten stuiteren op me bureau .
maar op laag volume klinkt deze subwoofer ook gewoon heel mooi net als de qsc k12s (de qsc k12s klinken nu nog veel harder en mooier omdat ze geen zwaren bass hoeven te verwerken)

De levering en service van bax shop was ook perfect !
