What's wrong with Velodyne?

I have two Velodyne subs. (HGS-12 and older one) and both have worked great, sound great, etc.

However, my experience with dealers is that they think very lowly of Velodyne and politely recommend staying away from them. One dealer used to carry them and dropped them, another well-established dealer said he though many other brands (some he didn't carry) would be better.

Is something going on here that I am missing? I don't think it's just dealers trying to sell products they carry.
