Zoef Posted July 5, 2015 Share Posted July 5, 2015 (edited) Guys, I have bought some b&c de750tn's for a 2 way cornscala project. Want to pair it with either the crites cast or kappa 15c woofers. (Depending on price. I live in the netherlands, so shipping can be a lot of money. ) For horns i want to buy some eliptrac's. I need some advice on crossovers. What would be the best to use? I see a lot are using the ap12-500 or 600. Would a es600 be a good option? Br zoef Edited July 6, 2015 by Zoef Quote Link to comment Share on other sites More sharing options...

Guest David H Posted July 9, 2015 Share Posted July 9, 2015 AP12-600 works perfect for the combination you are contemplating. Dave Quote Link to comment Share on other sites More sharing options...

Zoef Posted July 30, 2015 Author Share Posted July 30, 2015 (edited) Got a great deal on a pair of horns, the guy who sold me the de750tn drivers had a pair of volti fc260 horns. Got a very good deal so i could not pass on them. "Problem" now is, i need to make it a three way. Got my eye on some beyma cp25 tweeters. Also, my wife agreed on changing to klipschorns. So maybe i have to make a new topic of this. If i understand correctly reading on the internet the beyma's "like" a gentle slope crossover. (Am i wrong?) So a maybe a ap12-350 and ap15-6000 would be the way to go? Need something that i can build myself. Shipping and taxes and some more taxes and than customs and some more taxes are taking the fun out of the project. On most parts the shipping alone is more than $100 to europe. ( ok, as a plus, the beyma's are cheap overhere) Also, the de750tn is way more sensitive than the beyma, do is still need a tweeter attenuator? So, to be clear, the project has changed into a klipschorn P.s. Don't want to offend anybody. I know a lot of members here are shop owners. Everybody needs to make a living and i very much respect that. I simply do not have the money to buy the goods ready made. (for example, very nice crossovers) Most goods are almost double in price because of taxes and shipping. So for me diy is a big thing. And yes it gives me a very good feeling that i was able to make it myself. Everybody is proud of selfmade things. I have build a lot of speakers and crossovers over the years, so yes i know i need to respect the given values. And i know what goes wrong when i change one of them. If a schematic is posted here i assume i can use it for my own. ( not for commercial use ofcourse) So please be gentle with your comments [emoji4] Edited July 30, 2015 by Zoef Quote Link to comment Share on other sites More sharing options...
