bonsairich Posted March 11, 2009 Share Posted March 11, 2009 Hello, I want to build a Cornscala with a seperate ported bass bin. I have read that it is bad for a 2'x2'x2' cabinet ( because of the soundwaves)? Can somebody help me out with some information here, as I would be willing to build it 24x28x20 if that would make a difference sonically. I believe the wood Trachorn that I will use will fit with a 20" depth. Either way it will have the cubic feet needed for bass to compare with a Cornwall. My original Cornwall built last summer is the exact dimensions of a Cornwall with a much bigger horn. All Crites drivers and crossovers, but now looking at a ALK Trachorn, a Beyma tweeter, with Crites woofers, and probably ALK crossovers, also looking ahead already to a larger format using Greg Roberts horns. Anyway, what about the dimensions? thanks, Rich Quote Link to comment Share on other sites More sharing options...
CIGARBUM Posted March 11, 2009 Share Posted March 11, 2009 Do a search on the forum, there is a ton of stuff on the Cornscala's. I'm presently building a pair, look under Cornscala - again CB Quote Link to comment Share on other sites More sharing options...
Guest David H Posted March 11, 2009 Share Posted March 11, 2009 DIY Cornscala iss getting very popular. Here is another Cornscala link. http://forums.klipsch.com/forums/t/109953.aspx?PageIndex=1 This is a link to JW's Cornscala build, has all of the specs etc. Quote Link to comment Share on other sites More sharing options...
greg928gts Posted March 11, 2009 Share Posted March 11, 2009 I plan on making the V-Trac horn as a separate horn for DIY'ers to use. I can also build the horns into a cabinet, leaving space for a tweeter to be mounted. I'm thinking that an angled top cabinet, like the ones used on top of Industrial Split La Scalas would look nice and be very flexible for use on top of any of the various Cornscala type bass cabinets. Making another batch of just the horns coming up in a couple of weeks. Greg Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted March 14, 2009 Share Posted March 14, 2009 A cube is the WORST shape for a speaker cabinet. Standing waves galore. Even the most basic speaker design text will offer that. Quote Link to comment Share on other sites More sharing options...
BEEKMAN Posted March 19, 2009 Share Posted March 19, 2009 I Bad. I built a cube bass bin and think it sounds pretty good. Huh, makes me wonder how much better it would sound with different measurements. NOT! Quote Link to comment Share on other sites More sharing options...
CIGARBUM Posted March 20, 2009 Share Posted March 20, 2009 I understand that the cube is the worst, but how far off the say 24x24x24 do you have to get. Is 23x24x25 a lot better or just a little better?? CB Quote Link to comment Share on other sites More sharing options...
jwc Posted March 20, 2009 Share Posted March 20, 2009 With the plans I posted before....the bass cabinet isn't exactly a cube. But close. Didn't matter....sounded great. http://forums.klipsch.com/forums/storage/4/1071530/cs4.pdf http://forums.klipsch.com/forums/storage/4/1117459/woodorderallgrill.pdf jc Quote Link to comment Share on other sites More sharing options...
REN Posted March 20, 2009 Share Posted March 20, 2009 i made mine at 27in H x 25 3/8in W x 20 in and the bass sound outstanding and tight Quote Link to comment Share on other sites More sharing options...
colterphoto1 Posted March 23, 2009 Share Posted March 23, 2009 look up 'golden ratio'. Quote Link to comment Share on other sites More sharing options...
CIGARBUM Posted March 23, 2009 Share Posted March 23, 2009 I do know that Golden Ratio is still in effect from everything from building construction to furniture. It works very well for a two dimension shape, and it is amazing how many thing fall very close to that ratio. When you get into the 3 dimension stuff it get more complicated and really doesn't look that pleasing to the eye. Typically the 1.6 to 1 works well for a speaker and the depth is adjusted to make the correct volumn that is needed. Kind of interesting stuff.

Mighty Favog Posted June 11, 2010 Share Posted June 11, 2010 What about lining the inside of a cube shaped bass cabinet with some sort of sound absorbing material such as Dynamat or others?? Also, does it still count as being a cube if the measurements include the area only above the port shelf or including what is below??

Pete H Posted June 13, 2010 Share Posted June 13, 2010 Mine are 22.5 W x 30 H x 20 D for the bass cabinet. Keep the internal volume correct and you have some flexibility. Use JWC's calculations from his build where he did all the calculations on the volumes when removing the mid horn and tweeter and go from there. I worked mine backwards based on the overall height that I wanted and what the mid horn cabinet had to be and went from there. This is a very straight forward build that produces great results.

hklinker Posted June 14, 2010 Share Posted June 14, 2010 When I was trying to decide on whether to build my Cornscalas or just retrofit the old cabinets I consulted with Bob Crites who has an excellent web page describing his Cornscala project. He told me that the volume of the cabinet should have a minimum volume of 6 cubic feet. Before I had a chance to build it out, I came across a pair of cannibalized cabinets for fifty bucks so that solved that problem! Quote Link to comment Share on other sites More sharing options...
