After seeing yours I regret my decision (Too late now ... sold my extra set of K-510/691's ) I'm not one of those people who hate to say "I told you so." So, yes, "I told you so." LOL. 1 Quote Link to comment Share on other sites More sharing options...

Either way, you got twin woofers, which was the most salient point. 2 Quote Link to comment Share on other sites More sharing options...
MenloBob Posted June 3, 2019 Author Share Posted June 3, 2019 Before beginning I swung by my local Woodcraft to get Kreg pocket hole screws for the build. Of course they had this great workbench with clamps on sale.. Not having completely simulated the response before building, I decided to do initial construction completely with screws. I wanted to be able to disassemble and make modifications if it didn't measure well. Now that I'm really happy with the response I'll disassemble and glue all the joints and then re-screw to make them extra strong. First I built the two bass bin cabs. The kreg clamps made it easy to get everything perfectly aligned and square. The backs are pocket screwed to the cabinet from the backside for removal. I nailed in a few cleats to hold the back in the proper position when the speaker is resting on it's face. Next up horn cabs.. 5 Quote Link to comment Share on other sites More sharing options...
MenloBob Posted June 3, 2019 Author Share Posted June 3, 2019 The horn cabs interior are 15x9.5" which fits the K510 snugly inside the frame. I had thought of making a single cabinet, but the K691 magnets are huge and a single cab would have been quite heavy. I finish nailed in some maple 1x2 blocks for flush mounting the K510s into the frame. Horn test fit into enclosure.. K691s off the horn to remove the bundled stand mounts. Drivers mounted into the open rear enclosure. Then sand down some supports for the drivers.. 3 Quote Link to comment Share on other sites More sharing options...
MenloBob Posted June 3, 2019 Author Share Posted June 3, 2019 Cutting baffles.. I used a circle cutting jig with a router to cut two holes in four baffle boards. Each motorboard is a sandwich of 2 3/4 boards. The inset depth for the KappaLites was almost exactly 3/4", so I cut the two front baffle boards to the exterior diameter of the woofers, and the back baffle boards to the smaller interior driver clearance diameter. KappaLites mounted to the front of the motor board. Motorboard is inset 3/4" to look like a heritage cabinet. Back view of motorboards which are attached with a ridiculous amount of pocket screws. I will also add some bracing when I glue up the cabs. I built these over Memorial Day weekend and I had the choice of building braces and not finishing the speakers or skipping the braces and seeing how they sound. Guess which one I chose? Just waiting for backs and wiring.. 5 1 Quote Link to comment Share on other sites More sharing options...
Heritage_Head Posted June 5, 2019 Share Posted June 5, 2019 I’m impressed 🤜🤛. So the 691 is that the b&c de-75 (top of the 904)? Quote Link to comment Share on other sites More sharing options...
MookieStl Posted June 5, 2019 Share Posted June 5, 2019 You do great work! Build threads are my favorite! Just a suggestion, but while you have everything opened up, a little cross bracing in the cabinet may be a good idea. Better to have and not need than need and not have. Either way, they look great and I am sure they sound just as good. Keep posting those pics! edit: went back and read the entire thread from the beginning. You have some experts involved in this build. If they say you don't need to brace, they would know better than I do. Mine is sort of a "belt and suspenders" approach. 1 Quote Link to comment Share on other sites More sharing options...

Thanks, I’m really happy how they turned out. I’m planning to add one crossbrace before I do final glue up before painting. Right now they are only screwed together so I could disassemble after measurements in case I needed to make changes. But they measure so good I didn’t see any need to make changes so I’ll be finishing them up in their current configuration. Probably wait until my parents leave as I’ve taken up enough of his vacation out here with the build to date.. 1 Quote Link to comment Share on other sites More sharing options...

Yeah I purchased a new 904-HF bundle, which includes the K510, a stand and the 691 branded b&c. I’m happy with the sound of the 691 and don’t see a need to upgrade any time soon. That being said, if I happened into a source for TADs I’d probably jump on it. 1 Quote Link to comment Share on other sites More sharing options...

Strange on my 904s it had the b&c sticker on the back of the driver. But on yours it’s says Klipsch 691. Not a big deal just has me curious why they brand them on yours. I guess they could have changed them over the last 5-6years (about how long when I bought 904s new) 1 Quote Link to comment Share on other sites More sharing options...
