The cabs themselves are 35" tall on a 1/2" base, 15" wide, and 13-5/8" deep without the grill. I believe the spacing on the tweeter/squawker/woofer is the same distance from the top of the cab as on the HII. The center of the ports should be 9-1/2" from the bottom of the cab and 3-1/2" from the sides. I've seen the ports listed as 3" diameter with 5" length which should tune the enclosure close to 40Hz with the K-24-K driver. IIRC the stock cabs are only 5/8" thick particle board so if you wanted to keep the same internal volume then you would need to expand each dimension appropriately if using 3/4" ply. The cabs are a single internal volume with no separate chamber for the tweeter/mids.

I had the BGE sitting right around 225°f. The pork loin was on there for a few hours until it hit about 135° internal temp. At that point I pulled it off and wrapped it in parchment and foil and the heat internally rose to about 150°f. Ive definitely overcooked it before and was really worried about it drying out but it turned out perfect.

After dinner, to celebrate the Packers win over the Lions, we went outside and threw the pigskin around until it got dark.

I smoked some pork loin on the Big Green Egg. I also made some mashed potatoes, collard greens, and fresh cranberry sauce.

The only time it matters is when you are buying new storage/shelving for your music and you need to make sure you have enough.

Sounds like something a spammer would post.

After running some measurements and checking what parts I had on hand and seeing how they modeled in LTSpice I just put a 1.3uF cap across the tweeter. green=CDX1-1412 wide open. orange=CDX1-1412 with the 1.3uF capacitor. brown=stock K-79. Honestly if I had another K-79 on hand I would probably just use it to replace the busted one I’ve got. But, since I don’t, it’s nice to be able to replace it with something with better power handling that can hang out past 20kHz. Time to go see if there are any lonely dogs at the local brewery and check out the classic rock cover band playing tonight.

Working on those KP-250. This little guy is a perfect fit although he’s a few dB hotter than the K79. I’ve got the crossover circuit modeled up in LTSpice but I’m going to get some measurement curves first before I decide how much I think I need to pad it down. Unlike another popular tweeter driver, this one gets all the way to 20kHz with no problem. It’s Saturday morning and I’ve got to make a cup of coffee and decide what what else I’m going to get done today.

Left side of the house from the pole. Conduit under the eaves around the corner of the house to where it drops down into the meter. 🧐

Power is coming in on the left side of the house.

Electret condenser mics do lose their charge over time. I’m not aware of any way to recharge the capsule but you might be able to find a suitable replacement capsule online. There is also slight possibility that the capacitor in power supply section of the control box has gone bad. I’ve got a couple of older Shure SM91 and one is pretty much completely dead and the other has very reduced output. Some of Audio Technica’s(and others) recent electret condensor mics have a much much longer projected lifespan due to changes in materials used and charging methods during manufacturing.

That’s about the way it was going.

Out listening to the piano man at the local bar. This dog belongs to my neighbor at the end of my street. He’s busy getting drunk and trying to hit on all the young girls. His dog is pretty nice though.

Well, there’s a reason I kept my interest to the pet dog. My estranged wife and I are still legally married…

Congrats! I hope the rest of the process goes smoothly for you.

I think only the fretboard was ebony on those. The 50’s era black LP customs used a one piece Honduran mahagony body. The headstock overlay is typically dyed black holly wood.

Butter is way healthier for you too.

It looks like my worries concerning the low pass nature of the plenum volume were correct. but, it’s much flatter than the K33 regarding the famous bump at 148Hz. There might be(probably are) better drivers out there for this but these were $10 each.
-
Correct. I think “shoehorned” would be the correct nomenclature. they are supposed to be wired in series/parallel with one woofer in each pair wired as if they were out of phase since they are facing the same direction. This should put everything correctly in phase while reducing 2nd order distortion due to balancing out any driver nonlinearities and vibration. or whatever. I don’t think the original version that Dennis made was ever measured and this might only be the second time anyone has tried this. The specs on the woofer suggest that it will work well but the plenum chamber firing into the throat can also act as a low pass filter and I haven’t really modeled that part of it in Hornresp.

I have several irons in the fire right now but today I’m trying to make some progress on another one of DJK’s ideas for the LS.
