I use these speakers for two months to stream background music for cocktails in the collection's outdoor gardens in front of 150 people on average, I fed with a 2x600 watt amp EV 4ohms in the CPS2, they support 200 watts continuous with a finesse and DEFINITIONS of mdium / treble worthy of monitoring speakers, the yield plus.Ils dvelopp have a 20 cm long that descends elongation of 48 Hz so serious convincing for such a small volume.
They are so low that I quilibrsmme uses them home.
Bought for around 500 euros Thomann is a choice that I ever did without hsiter.
