Good product, terrible handling/delivery
Dabigartur 06.05.2021
I got it and was a bit afraid because it had no reviews. It works perfect, sound deep and rounded.
It was used for an outside party and worked perfectly for the purpose.
The quality of the case paint I think could be a bit better.
Worst thing was the handling of the product: the delivery was delayed for 2 weeks. The issue seems to be that the handling company (SEUR) wasn’t prepared to handled a package this big and they gave me a lot of issues to deliver. They didn’t treat the package as fragile and to bring it to a second floor they roll it up the stair way. A DISASTER.
Please Thomann, for big packages make sure that the transportation companies know about the product so they bring the necessary resources to deliver in good conditions.

Die Scheiben klirren und die Wände wackeln. Der Subwoofer tut was er soll.
