Cornscala Build

Recommended Posts

Well I'm finished with my Super Hersey Build and now on to a Cornscala Build.

Right now here is what I have decided to do,

 

CABINETS

Will order from Bob Crites Russian Birch unfinished

Looks like I can't get just cabinets unless I order all internals also..I will need to look around Lafayette, La area and see who I can contract to do them.My shop is not equipped to do the level of work I'm looking for.Any suggestions would be appreciated

 

WOOFFER
Eminence KappaFER Pro-15LFC 15" Professional Low Frequency Woofer 4 Ohm

Eminence Kappalite 3015lf4. Low Frequency Woofer 4 Ohm ( Possible Change ) 15 Nov 2019


MID RANGE 
B&C DE85TN-8 2" Titanium Horn Driver 8 Ohm 4-Bolt

B&C DE750TN-8 2" Titanium Horn Driver 8 Ohm 4-Bolt ( Possible Change ) 15 Nov 2019

B&C ME60 2" Constant Directivity Horn 60x40 4-Bolt

 

 


TWEETER 
B&C DE120 1" Neodymium Mylar Compression Driver 8 Ohm 2/3-Bolt

Daves MAHL Version 2.

 

CROSSOVER NETWORK

ALK AP12-500

ALK ES5800

 

Please chime in with any thoughts.Have purchased only the crossover network as it will be the longest wait time for it.

I will start sharing photos as I get parts together and cabinets in hand which I will order this week.

I made some additions to the list as I get suggestions from Forum members.

 


Here a picture of the super Hersey I finished last year.. Ready for a new project..

Nice build list. At some point, I will do the same (some time down the road).   Will keep an eye on this thread. Thanks for sharing.

No problem will try to keep it current. Love to do the cabinets but have limited space in my shop.

Nice.  The super Heresy is a awesome speaker. I built mine last year.  I would give your woofer selection a second thought. Claude just advised me to use the kappalite 3015lf4.  Says it's a much better woofer than the 15c.

If I can make 2 suggestions. 

ALK ES and AP12 networks expect to see a predicted inductance of the voice coil. Meaning that it’s set for a K33/K43 woofer.  The Kappa 15C has been measured by Al and is also compatible.  If you use something different the crossover could not be expected to perform as predicted.  Maybe it wouldn’t matter. Al and only a handful of other people can do the level of calculations needed.  In short, use a k33 or kappa 15C or ask Al. 
 

Secondly, the DE85 is lovely, is perfect especially for this application. That said. The DE750 was a monster. Bass was much improved.  It’s the same diaphragm but 2x the magnet.

I didn't know this. What would the alk universal be compatible with?

The universals are 6db filters and don’t have same issue.  I’d want a specific woofer then the cornscalawal but I’d want higher older filters... need to be kliapxh compatible with k33 or 15C

Thank You will check on it.

Are you discussing a cornscala or super heresy. The 15c is a suggestion for a cornscala.  I believe the original post is about building a cornscala.  He was showing his previous efforts with the super Heresy.

The kappalite 3015lf4 is a 12” woofer. If doing a cornscala you need 15”. So, Buy a 15” from bob crites. He has 2 very good choices or get a eminence Kappa 15C from parts express.

Sorry Justin, but the 3015lf-4 is a 15" woofer.  I think that is what the 15 is in 3015.   Claude just used it in a super cornwall, says its 4 times the woofer of a 15c.
