Labs could be fitted easy with handles man.
I have seen all kinds of different "versions" of the lab sub.
Some were EXCELLENT-finished with stacking skids, proper handles, great finish etc.
Others skipped on the basic design "because it was to hard to build".
They did not perform well-I wonder why-------------
Handles and wheels are something that BUILDER should be adding to suit their needs, not the basic acoustical design that Tom Danley did.
The "form factor" is the easy part. You just have to want to do it. Of course it adds costs and build time, but that was part of the idea of the whole project.
To provide a basic design that would perform well, and let people customize as they wanted to.
Sorry, but when somebody complains about "lack of handles"-that is their own fault for not putting them in.
