No PCB on the KP2.0A crossover. Maybe later versions used a PCB?

Do not get steel wool anywhere near your horns/compression drivers. Small pieces can get pulled in via the magnet and lodge against the diaphragm. Various scotch brite finishing pads work great for application and buffing.

Corner placement and room size can help with the low end response but if you are used to listening to a speaker that actually goes lower then you will notice a difference. My living room speakers are reasonably flat to around 35Hz and they sound much more full on the low end compared to the stock original style LS. that being said, what others have stated with regards to giving the new LS some time to break in is also a good idea.

I would have gotten some passive speakers to use with that amp.

There are way more than two options out there. Ports would work for the additional volume in the larger box size as well. A piece of 3” schedule 40 PCV is cheap and one could chop ports at different lengths until they found the sound/measurements they wanted.

Last night was good. Country music isn’t normally my preferred genre but Andy Buckner put on a great show. However, my buddy and I both forgot that last night was the town Christmas parade. I looped back around and parked in the park and took the foot bridge across the river and then hiked through town to where the show was happening. It was just over .5 miles and the weather was nice and brisk. It would have taken over an hour to wait for the parade and traffic to clear out. For lunch I just took some more of the smoked pork loin and sliced it thick and then fried it with some breading. It makes a fantastic sandwich that way. Oh yeah, there is a new music(guitar) store in the next town over. My youngest and I went to check it out yesterday afternoon. Nice stuff, but nothing that compels money to leave my pocket.

It's possible that the port tubes were removed on Ben's T-400. I think that a port the depth of the baffle on those would cause a really large peak in the response around 75Hz.

Leftover pork loin sandwiches. Some country singer guy from The Voice is playing in town tonight. I think my buddy and I are going to go check out his show.

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.

I swear I’m not really a stalker.

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.

Sunday night in Josh’s noise lab.

He was the best kitty. But little Mr. sawdust for brains was also the best kitty.

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.
