Horn/TL combo - Page 18

buzzforb · 30th October 2012, 08:01 AM

I am most likely going to use a router jig over a hand plane. Been thinking about how to have smooth contour in corners joints. May have some ideas that i will try. This will allow round hole at entry to continue as smooth transition vs changing to 90 degree sides. Got one size partially laid out already.

buzz,

maybe...a profile track swung about the pivot point...?...with a stylus that bears upon the side profile...?...do most of the stock removal with a surfacing bit...?...and switch to cove bit along the edges...?...leave a shoulder at the top of the cove along the edges of the top & bottom pieces...?...inset the curved sides to cover the shoulder?...

Very similar to what i was thinking. I will take pics of different trys to have if successful.

Did you get my response to your 'buying used' PM?

Only got one response. Figured i had worn you out. I got the Altecs at a good enough price (cost of one ,new) that i cam send them to GPA if necessary. Three of four appear to be in very good condition with 4th one having a repair.

Only got the one PM from you, but no response back.

Ah!. Thought I sent a second in email form. May not have worked.

I know you have stated that getting new from GPA is easier than messing with older drivers that made need work. I dont disagree at all. I simply went this route as it allowed me to try something for a great deal less than new. The side by side double will use the 414's, unless you think the MTM setup is better for my room. I buoght a pair of JBL Le15a's in good shape off a local guy that I will put into the single woofer version. Based on what i hear, I will decide where to go from there. This is really a step into nerw territory for me, SO i have to decide if I even like the concept. I will measure all the drivers and post info. I have been playing with WinIsd and Unibox for all the above drivers as well as the ALtec 515 and got what seems to be very usable reponses, especially considering EQ. Working on wooden horn layout today and trying to flesh that out. Any opinions on which dual driver setup to use, considering my room?

I have decide to do first draft of horns in MDF. IT will help me work out my kinks and try some ideas for cheap. THought about normal framing wood, but MDF is ore consistent.
I have more motivation now.

Dman these things are huge.
