Sneak peak into my latest project... pics ;)
So I finally got to the point I'm ready to veneer...
after over 300 man hrs working on this... 1.5 months... $4700... and blood sweat and tears...
there's something to show everyone
these speakers are "inspired" by the Avalon Sentinel... the front view is quite similar...
unfortunately the pics were taken at night... so it's hard to see EVERYTHING nice about these speakers
the bass cabinet is identical to the Sentinel... with the large triangles cut in the corners ... but a little more "low profile" than with the real sentinel
the bass cabinet has 2 curved walls.... which were built around a frame with 3 3/4" MDF supporting braces and the 1.5" top and bottom
the top and bottom are supported by 1.5" dowels in the rear... this gives quite a bit of added strength...
the curved walls were made up of 4 layers... first layer was .25" birch .... which was curved around the shape... then 9 layers of fiberglass mat and resin were applied to each curve.... making it 1/2" OF SOLID GLASS. at this point it's strong enough.... way more than strong enough... my 250lb friend jumped up and down on this and zero flexing occured... however over top the fiberglass one layer of 5/8" birch ply was layed... then another layer of 5/8" pine ply
the backs are 1.5" MDF...
the baffles are 1.5" MDF... routed out to flush mount the 15's...
they were then reinforced on the inside with 4 layers of fiberglass... this is so ridiculous and unneeded... but I was paranoid
the whole bass cabinet is ported to 32 hz... and is roughly 10 cubes
the cabinet weighs in at 250+ lbs without the speakers
the front of this will have 1/8" rubber on it just like the sentinel
the pics are again hard to see... but there is a "gap" between the top and bottom parts just like the Sentinel... which will be rubber also
the tops are angled on... well every side
the midranges are flush mounted into a piece of 5/8" with 60 degree edges to cut down on defraction off the baffle
they are in an irregular triangle box that's internally chambered specifically for the optimal performance of them
the tweeter opening fits the oak flanges I made for the LCY copy ribbons I made...
they're getting veneered tomorrow... with 2 4x8 sheets of precision matched walnut burl
then I whip out the HVLP and put on 10 coats of lacquer
