It's the hockey pucks. 😉

Ha avguytx,

   How right you are about rooms being a downfall or advantage.  I have not yet even tried to place my Heresy 2 plus speakers yet.  I need to finish them first  and have them fully run in.  I will get that veneer on when it warms up a bit.  I need to order glue and don't want to pay extra for guaranteed non freezing shipping which I don't trust anyway.  A little too cold here right now.  Good info on the Tangent speakers.  I am still sorting mine out and have to figure out what if anything I want to do with the K 53's in them.  Do I put new Crites phenolic  diaphragms in them? In the mean time I will build my slanted risers and put the hockey pucks back on the ice.  😉

It is hockey season after all!  Nice work, stay dangerous and have fun with those.

Keep your stick on the ice and a smooth seam is the sign of a true craftsman are two of my favorite sayings from my hero, Red Green.  🙂   Back to a speaker related question.  I spoke to Bob Crites about the upgrade to the K 53 diaphragm.  He didn't think the titanium version would be much of an improvement but he does have a phenolic version that he says does have some advantages.  I trust Bob's advice and I am wondering if any of you here have used one of his upgraded diaphragms  for the K 53 squawker and what impression you have?

This weekend I put my Heresy 2 plus project speakers as I am calling them  together just enough to give a listen.  A bit of background on this build.  I used stock K76 Tweeters with Crites Titanium diaphragms, stock K 53 mids and Eminence Delta Pro 12-450 A woofers in a cabinet designed and tuned for the woofer. So roughly 1.25 cu ft larger than stock Heresy cabs.  Rear 4 inch ports and Crites crossovers.  I couldn't wait for the damping foam to arrive so the sound check was a bit bass boomy.  I could have thrown a pillow in each one I guess.   After running them for a couple of hours to help the woofers settle in I gave a listed with some variety of music.  Granted, foam will help the bass a lot I should think but it doesn't sound too bad.  I think the squawker is a bit on the weak side and maybe I will have to attenuate the woofer a bit to give it more of a chance.  Unless you have suggestions on improving the K 53.  I have to confess I know just enough to be dangerous in building speakers so please forgive me here.   Any suggestions are appreciated.   One thing for sure I will not be needing my sub woofer in this set up.  Bass is very strong with the larger cab.  I still have to build slanted risers and install my walnut veneer but I just had to listed for a bit first.  My Canadian friends may appreciate my temporary hockey puck risers.  🙂

Very nice.  I am running some Tung Sol KT 120s and some vintage Mullard 12AT7 and 12 AX7s pre amp and power drivers.  Fun stuff rolling tubes.  

[Crites crossovers and diaphragms are awesome in Heresy’s!]

I also have to say that Bob was extremely helpful and very prompt at answering all of my emails as well.  He must spend about 25 hours a day answering emails from all of us.  Even on weekends when he should be off doing something else, he answers emails .  The guy is amazing.

I use a Jolida integrated tube amp that puts out about 60 watts per channel.  I am getting itchy to get the cabs done enough to mount the speakers and have a listen.  Staining and finish work can wait, right?  😉

Nice. What are you using for drivers?

I am using Eminence Delta 12 A 450 woofers, stock K 53 mids and K 76 tweeters with  Crites titanium diaphragms.  Crossovers are Crites H 2 s. 

[Super Heresys at 105db]

Those look great.  I will be working on my cabinets this weekend.  I just finished cutting the motor boards today and hopefully will get the rest of the cleats and supports glued in on Sunday.   I am anxious to get them into listenable status.  The new cabs I am building will add about a cubic foot to the interior volume.

[K 76 K compared to K 85 K tweeter]

I am restoring some H 2s  and have purchased the titanium diaphragms for the stock K 76 k tweeters.  I also have a set of K 85 k tweeters which have the same size diaphragms and horn mount size.  The magnet structure on the K 85s is larger than the K 76.  Would there be any advantage to using the K 85 drivers on the K 76 horns or would that screw up the balance with the K 53 squawkers?  By the way, I am using new crossovers built by Bob Crites. Thanks
