mopardave Posted May 11, 2019 Share Posted May 11, 2019 B&C de85tn is listed as being 8ohm. Anyone know if its available in 16ohm?These will be used in my Cornscala build. Quote Link to comment Share on other sites More sharing options...

mopardave Posted May 14, 2019 Author Share Posted May 14, 2019 I received the B&C de85tn drivers today. Quantity was listed as 1, so I ordered 2. I received 2 pair. They are 2 per box. Listed as $227 for quantity of 1. I paid $454 for what I thought was 2 drivers so did I get an extra pair for free or did I just order wrong? 1 Quote Link to comment Share on other sites More sharing options...

You lucky guy Last time I looked they were about $300 EACH. OK; the big question is "are you going to keep the extra pair or send them back?"

JohnA Posted May 17, 2019 Share Posted May 17, 2019 The 8 ohm impedance will require crossover mods, but will give you a nicer system impedance curve. Quote Link to comment Share on other sites More sharing options...

John, what change would need to be made on the DHA2 to switch to an 8 ohm mid? Bruce Quote Link to comment Share on other sites More sharing options...
JohnA Posted May 17, 2019 Share Posted May 17, 2019 If you have the swamping resistor, you should not have to change anything. If the squawker efficiency is waay less (unlikely) we might have to recalculate the squawker band-pass components. The beauty of Al's swamping resistor is that large increases in "apparent" impedance have less effect on the crossover. 1/10 ohms + 1/30 ohms = 1/i, i = 7.5 ohms 1/10 + 1/60 = 1/i, i= 8.5 ohms. But 1/10 + 1/10 = 5 ohms Quote Link to comment Share on other sites More sharing options...
Marvel Posted May 17, 2019 Share Posted May 17, 2019 Thanks John... I've swapped in a K69 on a different horn (until I get the MWM bins here, hopefully next week). My son is going to be getting the LS and I will probably pass on the MWMs after a while. Older son and I would still like to build a set of University Classics. He is making sure he can cut the angles correctly for the throats on them first. Bruce Quote Link to comment Share on other sites More sharing options...
