coolhandjjl Posted August 5, 2013 Author Share Posted August 5, 2013 Thanks! I bought a piece of curly/tiger maple, and I plan to add a piece of trim around the front. With some deep amber shellac, it will tie into the fender tweed on the bass bins. Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted August 5, 2013 Share Posted August 5, 2013 Yeah That's a Very Classy Look .I really like it . Hey what tweeter is that ? are you running actives ? Quote Link to comment Share on other sites More sharing options...
coolhandjjl Posted August 5, 2013 Author Share Posted August 5, 2013 It's a Linaeum ET6. Mid 1980's era I think? Mylar dipole, superb sound, lousy efficiency. But it's Time Aligned! [H] Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted August 5, 2013 Share Posted August 5, 2013 I love the way you did your rack . gives me some ideas are the units supported just by rods ? running across to the other thick boards ? makes for a cool rack pun intended Quote Link to comment Share on other sites More sharing options...
coolhandjjl Posted August 5, 2013 Author Share Posted August 5, 2013 Oak dowels are used to support the gear. I think they go in the blocks 3/8" or 1/2". They droop a bit under heavy loads though. The block ends are stacked onto each other with 3/4" pegs, spaced apart with plumbing fittings. My design makes it super easy to swap gear in and out, mess around with interconnects, and everything gets more than adequate airflow.

Guest David H Posted August 5, 2013 Share Posted August 5, 2013 Here we go! You can start to see the humps in a couple of the pics because of the studio lighting, but in real room viewing, it looks smooth. They look perfect to me, and love the equipment rack..

coolhandjjl Posted August 8, 2013 Author Share Posted August 8, 2013 Thanks for the great comments everybody. I feel like one of the boys now. Now I can safely reveal to the world that I actually like loudness buttons sand tone controls! [:$] Quote Link to comment Share on other sites More sharing options...
coolhandjjl Posted August 12, 2013 Author Share Posted August 12, 2013 Regarding tweeter height placement, isn't there some rule about placing the centers of the drivers within 1/2 wavelength of the x-over point? 5kHz @ 24dB/oct LR, so roughly 3 cm away? How do you do that with a horn taking up all that space? Or can you mount it a defined distance much further above that 1/2 wavelength? I mounted it far back to time align it.

Guest David H Posted August 24, 2013 Share Posted August 24, 2013 Here is the first set of Plywood Eliptracs. I recently found a source for low void true 3/4" plywood that is not that difficult to sand. Dave Quote Link to comment Share on other sites More sharing options...
Marvel Posted August 24, 2013 Share Posted August 24, 2013 Wow! Very nice, Dave. Will you offer them with the ply instead of the mdf? Those look nice finished that way. I must back away from the computer... I can't afford these, but [Y] Bruce Quote Link to comment Share on other sites More sharing options...
Guest David H Posted August 24, 2013 Share Posted August 24, 2013 I may offer both of them, these are a lot more work. I will certainly make them both available in kit form. Dave Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted August 24, 2013 Share Posted August 24, 2013 I may offer both of them, these are a lot more work.How so Dave ? ? assembly or sanding ? ? OR R they harder to produce ? ? they are Real PuurtY hey Dave , have you ever tried using solid 3/4" boards ? Quote Link to comment Share on other sites More sharing options...
Daddy Dee Posted August 24, 2013 Share Posted August 24, 2013 Dave, those ply eliptracs are beautiful. You mentioned they are easier to sand. could you say more about that? Quote Link to comment Share on other sites More sharing options...
muel Posted August 25, 2013 Share Posted August 25, 2013 Is it just me or are these really thick plys? I cannot imagine being able to sand plywood edges so smooth like that! Very nice! Quote Link to comment Share on other sites More sharing options...
Guest David H Posted August 25, 2013 Share Posted August 25, 2013 You mentioned they are easier to sand. could you say more about that? This is maple 5 layer plywood. The maple is much easier to sand than birch, but it is still far more difficult to work with than the MDF. Dave Quote Link to comment Share on other sites More sharing options...
