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. 😉

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.

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? 😉

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.

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. Dave

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
