Too answer all of the above succinctly:

I already have a good idea of how a 2-way (cone & dome) performs on my desk. It's good. Even with $15 drive units it's better than most headphones. The idea of this project is to scale up the driver capability and see what sort of concrete gains I can get out of it. I'm not going to worry about the flurry of acoustic issues that are always there with speakers.

Rest of the components came in yesterday and I finished putting them together today.





Took care to use recessed binding posts, much nicer for the application

used pricy flat-foil inductor in series with woofer

Some minor nicks on the baffle cutouts, nothing that bothers me. I'll probably apply some tung oil later. Just started listening tonight. More to come.

Wow that is a strikingly shallow enclosure.  I never see them like that.  Always assumed it made it sound bad

Still adjusting cabinet filling. Might need to stick some dynamat on the rear if I feel that the shallow depth is a problem.

So, can one of you build me a better speaker than a KEF LS50 for the same price? :)

Marv, is something like this BS?

http://www.parts-express.com/acry-tech-acoust-x-1-gallon-absorption-coating-paintable-damping-material--260-105

Never used it. Probably no different from roof asphalt stuff for three times the price.

Possibly, but if you like and want the LS50 sound, get an LS50. The mini-monitor OJ is building above will probably sound better than the LS50. Then, again those Seas and Scanspeak drivers are extremely expensive.

Yea, no dynamat crap. Too messy and not as effective as people say it is. Plain ol pink fluffy fiberglass is lot better but, your cab is very small(depth wise specifically) especially for a bookshelf speaker. I wouldn't get that paint goo either. Can find very similar local home dept or even Walmart hardware department. They have paint/ spray on rubber as well but, I wouldn't use it for internal enclosure section.

I never tried foam stuff that Marv listed but, it does look good and best option so far. I only ever used plain ol' fiberglass with sometimes combination of fiberfill/pillow stuffing. Never did anything fancy ever with speakers. I know some people fill their enclosures with bags of sand or concrete but, never found point of that either.
