I'll build a all new center cabinet as well . I'm Jazzed been Really bored as heck .. as of late ... Now I have a plan loooking forward to putting the kit together ....

ZombieWoof Posted July 20, 2012 Author Share Posted July 20, 2012 got off the phone with Dave , I'm on the road to a set of 2-ways I'm gonna build 5 . I'm gonna do a center horizontal as well , I'll do this as build thread & keep it up-dated as I build . Quote Link to comment Share on other sites More sharing options...
jbsl Posted July 21, 2012 Share Posted July 21, 2012 What is the advantage of two way over three way? Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted July 21, 2012 Author Share Posted July 21, 2012 less over lap between drivers. More knowledgeable people than me can chime in here, on the reasoning. but they sound better to me I'm going with the ALK crossover AP12-500 the B & C DE-85TN 2" HF driver Bob's 15" cast AL woofer Quote Link to comment Share on other sites More sharing options...
jbsl Posted July 21, 2012 Share Posted July 21, 2012 I've never had the chance to compare the two. Maybe someday I'll build some CornScalas and try it 2 & 3 way. Quote Link to comment Share on other sites More sharing options...

germerikan Posted July 24, 2012 Share Posted July 24, 2012 This should be interesting, I am in the middle of a CS1.5 build and just need the internals. Will be interested in your oppinion on the differences between the 2. Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted July 24, 2012 Author Share Posted July 24, 2012 I can not comment on the comparision between the CS-1.5 over the ElipTrac-400 in a 2 way Corn Scala , until I get these built . But I can say the CS-1.5 is a solid performer for me as a center , height & wide , They are the reason I am up-grading to the ElipTrac-400 . They showed that there something lacking with the CornScalas with the CT-125 Tweet & the Atlas /Klipsch stock 1" driver & the PH-800 horn lens I really liked the CornScalas that Bob Crites supplied the mod parts for but as this was one of the early versions , I think he has very much improved the newer versions . I find it's hard for me to find the words that would describe the difference between the 3 way CornScala & the CS-1.5 a 2 way , I can say they sound Great both in the same mix when I run them all at the same time . The 2 way just seems to be a more presence at play . Running 9 Hertitage style speakers in a Home Theater is a very Dynamic & Stunning Quote Link to comment Share on other sites More sharing options...
bracurrie Posted July 24, 2012 Share Posted July 24, 2012 I am using the ElipTrac-400 with Faital HF-200 drivers. I am using an active crossover with a miniDSP. The results have been very pleasing. I like the two way approach. Quote Link to comment Share on other sites More sharing options...
ZombieWoof Posted July 24, 2012 Author Share Posted July 24, 2012 I'm now looking at building a top enclosure for the horn & network , I feel that the volume of the ElipTrac-400 is too much displacement inside the stock Cornwall cabinet When I added the PH800 horn ,that horn assy wasn't as huge as the 400 is . Plus this will allow me to have the horn assy higher to the plane of ear level . I will just seal up the present holes by adding a new motor board . I am entertaining moving the woof up to the highest part of the cabinet OR at least move to the center . basicly the Cornwall cab will now be a bass bin only . I like the size as is , that allows for a smaller foot print depth is a issue in my room , it's better to go high & wide rather than deep for the WAF issue. also by have a top hat so to speak that is seperate ,I can add a feature that would make the enclosure move up & down so that the horn could be aimed with a high degree of precision ordered the 2" driver............... going with a B & C DE750-16 Quote Link to comment Share on other sites More sharing options...
oldtimer1954 Posted July 25, 2012 Share Posted July 25, 2012 Wow Fastslappy that is the same approach that I am taking with my Cornscala build. I am building mine from the ground up though and instead of using a single 15 inch woofer, I am using 4 Dayton Pro-10's, just like Johnny5. Definitely keep us updated as I am very interested in knowing how you feel that the 2 way versus 3 way debate turns out! Quote Link to comment Share on other sites More sharing options...

Yeah I'll keep this thread quite active , no worries there I'm chomping @ the bit to get started As far as the reason I'm doing this build thread is because , 1st .... I was Soo helped by other member's great build threads here @ this forum. Those threads really helped on my 1st build when I was doing the conversion of my 4 '73 Cornwalls into the current CornScalas I now enjoy . 2nd .... Tossing my ideas out there for the members to comment on ,really did help me avoid many (& I do mean many) mistakes. That feed back from the many kind & helpful members saved me a lot greif on my build. 3rd .... to advance the knowlege base of the CornScala concept . I'm not the smartest when it comes to the design & concept of speaker building ,I do follow advice of people who clearly know more than I do .

justinsweber Posted July 26, 2012 Share Posted July 26, 2012 I think if you ask Dave The Elip400 is ok in a Cornwall cab. If you want splits thats a positive route. The single cabs simplicity has me charmed right now. Quote Link to comment Share on other sites More sharing options...

The single cabs simplicity has me charmed right now. the addition of a split cab is my leaning for two reasons the horn is higher nearer the plane of ear level , add in that I can aim the horn precisly as well 2nd I can make the bass bin in a designer style front with a single opening + the port then as pointed out on another build thread , i'll have the easy change up of horn/drivers as needed . my current cabs are doubled walled except for the motor boards so now I can very easily dbb that too.

Guest David H Posted July 27, 2012 Share Posted July 27, 2012 Here are predictions of the box with and without the Eliptrac I estimated the Eliptrac uses up approximately .5 cuft more air space than the K-600 and K-77 which changes the LF response by 2Hz, however re-tunig the port for the reduced air will easily get you back to the desired fc.

Dave I could place a .5 cubic sized block of wood inside the cab .That's what told Al I was gonna do. Thanx now I don't have to guess the size I quit guessing these things , I was going to do a displacement test but it's involved & messy ( I use sand in a controlled sized box)/you've saved me hours of time & a mess clean-up Dave that must be Great to have all those toys to figure this stuff out with HEY quick question Dave , is that a half round file being used in the DIY guide for the ElipTrac-400 ?? I checked my rat tail file ,it's seen better days Amazon Prime is send me 2 new files , I await the 5 kits .... check is in the mail ... HF drivers will be here Monday ,went with the B & C DE750-16 Quote Link to comment Share on other sites More sharing options...
Guest David H Posted July 27, 2012 Share Posted July 27, 2012 It is, but lately I just use 36 grit sand paper for the shaping, them move to 60 grit to fine sand before primer. Dave Quote Link to comment Share on other sites More sharing options...

Dave Dave have you changed any of the ways that you do the assembly of the ElipTac-400 ? Now that you've done them for awhile have figured out any tips & tricks that made the process go easier , than the outline that you have posted on your website ?

Guest David H Posted July 29, 2012 Share Posted July 29, 2012 Actually the way I show on the instructions still works well, bu t I have changed the way I do it. I no longer assemble the horn in sections, I now fully assemble the horn then sand. I dont use a rat tail file anymore, now I use a piece of 2 inch pcv pipe with a sheet of adhesive back 36 grit automotive longboard sandpaper attached. This sands much quicker than the rat tail, and lets me get down the throat more easily. The finish sanding is still all done by hand and and is very time consuming.
