DIY Speaker Kits, a good idea?

There are so many variables. I built a bookshelf enclosure from a plan from Markaudio that houses Alpair 10’s. I’ve tried them on a few different setups and felt they sounded pretty good. Recently I paired them with an old Harman Kardon A300 and have decided that I really don’t need to look any further. I have a couple decades experience as a carpenter and felt comfortable building them but I don’t think it’s beyond the skill level of anyone who has access to decent tools and maybe a friend who can provide assistance. Whatever the outcome, it’s a satisfying experience and I’d recommend doing so to anyone interested. Do some research first and find out about builds that might pair well with your amp/integrated/whatever

Building a really solid box seems to be a big chunk of the cost of some expensive speakers and there's cheap stuff at Home Depot and Menards that anyone could use to do this.  If you attached a porcelain floor tile to MDF it'd be near resonance free.  It'd cost next to nothing.

The key to having some resale is to pick a very good model to build from a well known vendor. If you go with something too obscure then there's a limited number of people following the design or vendor and without a following..tougher resale. 

I have the CSS 1TDX and 2TDX.  They were fun to build and sound awesome.  When you build something yourself, you have an extra attachment to it.  And the price to performance ratio is very high.

I have some homemade Magicos and melting that pile of aluminum was sort of intense but totally worth it.
