Thanks, jonbee.
Did you DIY them?
I'm in process of building them. I bought the chassis from member HT cOz (very nice, and fully precut and drilled for the project). I've gotten all the parts except the amps, on backorder with Hypex.
The project is fairly simple and straightforward as DIY goes. The Hypex modules are really well set up to make it simple. I expect a completion time of around 4-6 hours.
If you have no DIY experience it will be more of a challenge, but not impossibly difficult even then. Then I would certainly recommend the HT cOz boxes, as they are nicely setup for easy construction with no metal work required at all.
