I bought a pair of these to replace our old Peavey system which had been on the go for nearly 20 years. I spent a lot of time weighing up different systems for what we needed (usually a 3 piece band, 2 acoustics, cajon and 3 vocals but sometimes up to 6 members) and finally settled on the the LD Maui 11G2. I originally ordered 1 new unit and 1 B stock. I had problems with the B Stock but Thomann were extremely helpful and facilitated a replacement.
Firstly, the design. The system is well built and looks very slick. They feel extremely well built. We've had plenty of compliments and inquiries since we got it. The system is quite portable but the bins are pretty heavy. Secondly, and most importantly, the sound. It's incredible. I've used it for 3 piece gigs, 6 piece gigs and also with Ableton for electronic gigs, and the sound quality is amazing. I've used them as monitors when I'm mixing tracks in Ableton and Pro Tools and find them excellent. I use an old Behringer PMP1680s mixer and find it great, but I imagine with a top quality mixer you'd be able to coax and even better sound out of the system. We use it mainly for small-medium sized pubs and function rooms, up to 80-100 people max. Anything larger than that and you're pushing it and might want to consider the Maui 28 G2. One big issue I had with the system is that it doesn't come with covers for the bins and tops and they aren't cheap to buy separately. Overall though I'm very happy with the purchase and would happily recommend them.
