Thanks Vott, I think putting effort into my home made cabs would just be fruitless. those Heathkit cabs are made of particle board though and it doesn't seem very stiff or rigid? Unlike say solid oak? I was picturing solid oak with the speaker mounted to the baffle with a solid clamping system around the magnet would be the way to go? Also doesn't weight play a part too? the heavier the speaker is? or is that just my imagination.
BTW I don't think the heathkit cabs sounded horrible...they kinda sounded not good but after I switched the speakers back into my homemade cabs I realized the the HF leads needed to be switched around I think if I had done that in the heathkit cabs I'd probably still be running them.
