As a current owner with hundreds of gigs with my Flite rig, I can honestly say to the negative comments, those opinions couldn't be farther from my experiences.
I run a bi-amped rig with 1 15" with mid, about 135hz and below so the mid isn't even functioning, and 2 10" with Horn. I have replaced the horn with a Selenium since I like it better. Also replace the 2 10's with some Schroeders my uncle gave me. Each cab is 4ohms powered with an older QSC 1602.
As far as rattles go, my guitarists Marshall cab produces all the obnoxious rattle live. I've played outdoor shows and it pushes plenty, indoors it's fantastic. I like stacking them on an Auralex Gramma pad to help isolation. What's amazing with the cabs is if you feel the cab when other sounds like PA or drums are in the air they really do resonate with all sounds, very reactive.
Yes they are a sandwich of thin ply and foam, both my cabs are sub 30 lbs. and I can carry both into a gig. And yes these were pre Neo's at that weight especially with the 15. Originally I was dealing with Guy LaPointe when I got mine, and he got them to me in time to play a local Jazz fest. But this was well over 7 years ago. If I recall I got them within 2 weeks.
The only bad thing I can say is I had to glue the port back in the 15 as the wind it was pushing pushed it right out of the cab.
Oh yeah I've had several players say to me it's the best bass rig they have ever heard. Glad to see they are still around, but I haven't needed anything else in years and my back and ears thank me every gig.
Cheers,
Dirk
