sootshe Posted December 8, 2011 Share Posted December 8, 2011 Dave, Can this be used for the Cornscala DBB or be adjusted to suit? Thanks, John The HF section would certainly work, but the woofers in parallel poses a problem. The Impednece and inductance have both changed. What woofers are you using? Dave Crites cast frame woofers Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 8, 2011 Share Posted December 8, 2011 Crites cast frame woofers Because it's first order on the woofer, the crossover point change is going to be insignifigant. The impedence won't be near as flat, but it should work fine. Because the woofers are in parallel, the impedence drops from 6 ohm to 3 ohms, but the inductance drops from 1mH to .5mH so its a near wash.

Guest David H Posted December 9, 2011 Share Posted December 9, 2011 I ran the simulation on the DBB. As you can see from the graph the first order filter will work with either the single or DBB woofers, as long as the woofers are in parallel.

Guest David H Posted December 10, 2011 Share Posted December 10, 2011 Sorry Craig, no DBB's on the books, however I do have a new Cornscala I am starting on. Feaux Split-Box Cornscala. I will be using ALK Cornscala-wall crossover. Quote Link to comment Share on other sites More sharing options...
Autobocs Posted December 11, 2011 Share Posted December 11, 2011 Those look like the Cornscala's I purchased from you years ago, do I need these new crossovers. Paul Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 11, 2011 Share Posted December 11, 2011 Those look like the Cornscala's I purchased from you years ago, do I need these new crossovers. Paul No, the crossovers you have are ALK uiversals with tweeter attenuators, they are fine.BTW, good to see you on the forums, Welcome.

Autobocs Posted December 11, 2011 Share Posted December 11, 2011 Ok I will take your word for it. PB Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 17, 2011 Share Posted December 17, 2011 The first tweeter attenuator LPad is built and ready for testing. These LPads will be standard on the Cornscala-Wall crossover, however will also be available individually from ALK. Dave Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 17, 2011 Share Posted December 17, 2011 Good news, the crossovers are just under budget, and scheduled for release in January. From the ALK Engineering website >>>>> "Pricing will be $299.00 for a set of two. They will be available around the end of January, 2012."

Guest David H Posted December 17, 2011 Share Posted December 17, 2011 Lpads are listed here. http://www.alkeng.com/pad.html Dave Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 22, 2011 Share Posted December 22, 2011 First set is almost ready to go. Looks good AL, I love the L-Pad. Dave Quote Link to comment Share on other sites More sharing options...
Autobocs Posted December 22, 2011 Share Posted December 22, 2011 Looks good, although I wish he would have painted the boards like the UNI. Then again, my universals cost near twice what these do. PB Quote Link to comment Share on other sites More sharing options...

I am sure the cost, and the time it takes to paint the boards was a consideration, the objective was to keep the price under budget.Dave Quote Link to comment Share on other sites More sharing options...
BE36 Posted December 24, 2011 Share Posted December 24, 2011 Sorry Craig, no DBB's on the books, however I do have a new Cornscala I am starting on. Feaux Split-Box Cornscala. I will be using ALK Cornscala-wall crossover. If this is taller? And more narrow than a La Scala? This would give narrow roomed poeple more options.

hklinker Posted December 24, 2011 Share Posted December 24, 2011 Hi Dave Are these similar to the one's you help me build two years ago? I used the Radio Shack attenuators and ribbon foil inductors, and that set ALK off if I remember. Now that you two have smoked the peace pipe, how can I swap the RS attenuators out with a pair from you? Merry Christmas! Herb Quote Link to comment Share on other sites More sharing options...
Guest David H Posted December 24, 2011 Share Posted December 24, 2011 how can I swap the RS attenuators out with a pair from you? ALK is building an selling these crossovers and the resistive LPads. The resistive attenuators are $40 Dave Quote Link to comment Share on other sites More sharing options...
