DIY Speaker Kits, a good idea?

For my beginner DIY speakers I took a very easy rout to convince me I could build something I like and also to experiment. Purchased some full range single speakers (TangBand W8-1808 $850 msp,, purchased used for $400, no complicated x-over), researched there ideal box size/volume. Found a pair of vintage Noresco speakers whose size matched the ideal size and are also made of 3/4" ply, no pressboard).  Beefed-up the walls to 1" thick, braced inside, mounted extra 3/4" front baffle (now total 1 1/2" thick front baffle). Installed the speakers and wired up. 

WOW,, I am sold on single driver full range cross-overless design. Wider and higher soundstage, highs are natural and right there, and the mid's steel the show... blah blah blah..

Only downside is bass. None, just none. But I have dual SVS SB1000 pro subs and the two together are wildly good. No concert level volume, these are only 8" and they are doing it all out of one voice coil. Up to 75db 80 db they are awesome. Jazz, ambient, electronic really shine. They even have me looking left and right. If I close my eyes I can see the music coming out of the walls. It''s crazy.

Blah Blah,, Blah Blah

There's always satisfaction to be had doing something with our hands. We don't have to design crossovers or fine-craft enclosures out of raw materials; just assembling a kit is satisfying, As some folks remarked, you feel closer to your gear when you have skin in the game (I paraphrase). Feels that way when I repair broken gear too.

About resale value... it depends. A pair of big Linkwitz showed up on craigslist a few months back. Very good looking DIY build, the guy was a woodworker, but it had an older driver set. Asking $3.5K if I recall. Just in the time it took me to ponder whether they would be a significant enough improvement over my current speakers, they were gone. Meanwhile, brand name speakers get reposted over for months at a time.

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.
