Marvel Posted November 7, 2013 Share Posted November 7, 2013 The bass cab for the LS is right around 8 cubic feet... I don't see a problem here at all. Bruce Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 7, 2013 Share Posted November 7, 2013 That horn reminds me of my dream speakers...I'd like to at least cobble up some form of a copy before I expire... I have the L-475 woofers. Fostex%20LS3%20Poster.jpg Looks like a straight forward build. WAF = 0 Ill bet is sounds great. Dave Yeah, the bass cabinets are a rather simple design...except the fact that they are huge, like 9 foot internal volume or some such. Build the bass cabinets, and go from there. Wife Acceptance Factor is one of the least concerns in my life... 9 cubic feet sounds like a lot, but if you call it 1 cubic metre, it sounds much smaller. Gotta cube it not square it. A cubic yard is 27 square feet, a square meter is bigger, like a refirgerator. Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 10, 2013 Share Posted November 10, 2013 I have not made much progress wth these yet, I still need to make the driver adapter. I've been thinking about this. I was thinking about using poplar, but, wouldn't using a soft wood like fur be better? If will never have a load and can be sanded easily, then stained to make it look fancy. What do you think?

Guest David H Posted November 10, 2013 Share Posted November 10, 2013 I have been using an inexpensive Birch/Maple plywood for my prototypes, however I think Baltic Birch ply would be ideal. Because of this horns design, they are relatively easy to sand with a palm sander to get the basic shape, then hand sand the finish. I am going to spend some time on this horn today. I would like to get this to a point where I can kit this for DIY builds. Dave 2 Quote Link to comment Share on other sites More sharing options...

NBPK402 Posted November 11, 2013 Share Posted November 11, 2013 Those really look nice. How does it change the sound of a normal horn like in the LaScalas... Are they warmer sounding, smoother etc.? Quote Link to comment Share on other sites More sharing options...

Are they warmer sounding, smoother etc.? Not a clue, I have not yet heard them. I suspect they will sound good, because JBL, Fostex, and Altec have all had good success with similar designs.

NBPK402 Posted November 11, 2013 Share Posted November 11, 2013 Does wood normally have a different characteristic sound compared to aluminum? Quote Link to comment Share on other sites More sharing options...
whatever55 Posted November 11, 2013 Share Posted November 11, 2013 How would these compare to 402's ? They would look better Quote Link to comment Share on other sites More sharing options...
Rudy81 Posted November 11, 2013 Share Posted November 11, 2013 Excellent work Dave. Keep up the good work. I'll be heading into the workshop in the next few days myself to finally build my center channel HF horn. I have been working on my dust collection system for the past few months and can finally get to work. BTW, how are you getting the curved portion of the horn? Hand sanding? My top and bottom won't be as think as what you have built, but will likely have some 2 pieces of BB to curve. I can't wait to hear some listening reviews from you guys.

Guest David H Posted November 11, 2013 Share Posted November 11, 2013 The sound of the horn is more determined by the shape than materials. I like the sound of a wood horn, but I am relatively certain it is psycological. I dont think these would be a fair comparison for a K-402. The curved portion of this horn is cnc cut, then hand sanded. Dave Sorry I was not able to use the quotes. I reallt dont like the new site changes. 1 Quote Link to comment Share on other sites More sharing options...

That is some sticky stuff between the layers. Put a brad into it and it never comes out. Quote Link to comment Share on other sites More sharing options...
Guest David H Posted November 12, 2013 Share Posted November 12, 2013 I designed the horn to be built from .7" baltic birch, the steps are cut to 1/16", so the sanding goes fairly quick. If you were to build this horn as the original builder did, the steps would be 1/8 inch except for the bottom layer would be 1/2" Dave Quote Link to comment Share on other sites More sharing options...
tigerwoodKhorns Posted November 12, 2013 Share Posted November 12, 2013 So do you cut the pieces and then router the edges at 45 degrees and then sand? Quote Link to comment Share on other sites More sharing options...
