justinsweber Posted October 23, 2015 Share Posted October 23, 2015 (edited) Back at it with the cornscalas. We are calling this Project Hulk... I believe its the 1st time the Eliptrac 240 horn is being used. What we have here is the Crites Cornscala bin (additional bracing and some adjustments to the volume), paired with Kappa 15C. Baffles were done for use by Dave… CNC cutting at it finest. The Bass bins ride on a Base-plate with the caster bolted down. The Base-plate will be bolted to the bottom of the base bin. Will allow for easy movement. Top Hats are Eliptrac 240 2” horn with BMS 4592ND-MID crossed at 300hz with an ALK ES300. The HF is handled by the Dave’s Contrac horn and the B&C DE120 crossed at 4500hz with an ES4500. The owner wanted the inside of the mouths to be highlighted… they will have grills so only be present when off.

CECAA850 Posted October 23, 2015 Share Posted October 23, 2015 Very cool Justin. You might correct the typo in the title Quote Link to comment Share on other sites More sharing options...
justinsweber Posted October 23, 2015 Author Share Posted October 23, 2015 Part of my charm... not! I tried to fix... not sure how to. (Can you fix?) The bigger the speaker the more thought all aspects must get. (Kinda crazzy). I will just say that if you can have a parts present at t he same time it saves alot of worry.

You can change the title from there. Quote Link to comment Share on other sites More sharing options...

babadono Posted October 23, 2015 Share Posted October 23, 2015 Saw the picture of the crossover. So that's the ES300? My, my that some large inductors. Quote Link to comment Share on other sites More sharing options...
justinsweber Posted October 23, 2015 Author Share Posted October 23, 2015 No. That's why I took down. It's a ES500. Al just finished the ES300 and will be sending out soon. Quote Link to comment Share on other sites More sharing options...
justinsweber Posted October 23, 2015 Author Share Posted October 23, 2015 (edited) I thought we were first... Oh well. That said, where are you crossing to the HF? Dave said that the 240 begin to collapse up high and thus a 4500hz crossover point made sense. (Least I think was he said).

babadono Posted October 23, 2015 Share Posted October 23, 2015 Right now I have it running off an ALK ES KHorn crossover so that would be 5.8kHz if I'm remembering correctly. You mean I could/should crossover lower and it would sound better? Wow. Cuz it sounds pretty darn sweet already. I love how this big horn sounds (and looks).

justinsweber Posted October 24, 2015 Author Share Posted October 24, 2015 Just going by Dave and Als advice. I'm building a version with Eliptrac 400 es500/es5800 to directly compare. Crossovers are done so we should get to give a detailed listen within 2 weeks. What driver did you pair the 240horn with? Quote Link to comment Share on other sites More sharing options...
The Dude Posted October 24, 2015 Share Posted October 24, 2015 Justin looks good as usual, I like the contrasting colors. One look I all ways like was the black box with white grills. Not to burst both of your bubbles, but IF I remember right the 240 was design for Craig (or he was the one to convince Dave to design it) at NOSvalves, so he may have been the first to use it.

Guest David H Posted October 24, 2015 Share Posted October 24, 2015 Dave said that the 240 begin to collapse up high The polars on Tractrix horns in general collapse at higher frequencies, however the 240 will easily achieve 6k+. My meaning was the 240 simply can not be used 2 way. Quote Link to comment Share on other sites More sharing options...
justinsweber Posted October 27, 2015 Author Share Posted October 27, 2015 Drivers in safely inside the tophat. Waiting for the ES300/ES4500 and then we can play some music. Quote Link to comment Share on other sites More sharing options...
cradeldorf Posted October 27, 2015 Share Posted October 27, 2015 (edited) You'll likely get much better sound out of them if you eliminated the gaps between the floor and the bass cab as well as the one between the bass bin and the top.... but that's none of my business. Nice work by the way. Damn those casters are fugly... Edited October 27, 2015 by cradeldorf Quote Link to comment Share on other sites More sharing options...
CECAA850 Posted October 27, 2015 Share Posted October 27, 2015 Damn those casters are fugly... Agreed, but if that's what the buyer wants, that's what Jason will build. It makes them look like garage speakers. 1 Quote Link to comment Share on other sites More sharing options...
justinsweber Posted October 27, 2015 Author Share Posted October 27, 2015 The speakers are going into a design space, moving them around was a real concern. If they become a permanent install, the casters are mounted to a baseplate via t-nuts and are easy to fill. The footers on the top hats are more of an aesthetic touch... if they end up hurting the sound, they will be removed. The footers have a bit of suspension to them when is nice when moving the top hats. The horns are massive and I worry! The baseplates are being installed today, all t-nuts for the woofers, riser will be mounted, and the Cardis binding posts installed... All that’s left is crossovers and wire loom. 2 Quote Link to comment Share on other sites More sharing options...
