My wife needed some stuff at Hobby Lobby today and she told me they had a section of theater themed decorative items so I checked them out. They had some neat stuff, marquees, film reels, vintage look metal signs, etc. I bought this one, the regular price was listed as $24.99 but Hobby Lobby merchandise is either always on sale or they always have the 40% off coupon on the website that you can pull up on your phone and use at check out. This sign was on sale for $7.50.



We have another store that may be local only, I know it started in Omaha back in the 70's and I don't think it spread nationally but could be wrong. It is called Gordman's, used to be Richman Gordmans. We were in there as well and they didn't have theater themed stuff but they had a lot of bar themed stuff including some fairly cheap metal signs that had LED bulbs attached:

Cool stuff. Some of my fondest childhood memories were playing in that giant blue elephant in Richman Gordman's.

Last spring I came up with an idea to expand my garage with a two story addition:

The company I hired started the work this week. Hopefully the pictures show up OK.

Is the expansion garage space or something else?

Exciting either way. I have a walkout house with a garage. Hmmmmmm . . . .

Garage above and I'm not sure yet what to do with the bottom portion, maybe make that a beer brewing room.


Floor pour went in yesterday:

Two guys basically finished this thing in 2 days, the siding goes on today. It has been pretty cold here, they are probably motivated to finish it quickly.

It's been a wet couple months but now that things are warming up and drying off I've been making some more progress on the addition. I finished the electrical, insulation and flooring. Hiring out the drywall and the exterior painting. I'll do some finish trim work, paint the inside and then it is done!

Desertdome came back from a KC trip a few weeks ago and brought me a present - two passive JTR Caps and another Behrenger amp to power them.


They've been sitting in a corner while I've been waiting for a break to have time to play around with them. There is also the matter of having to take down the screen, move the Danley out of the way and then put these in place and re-hang the screen. All of this can't be done with one person.


Last night I had some help and we set aside time for listening tests. The test scene we used was the weapons team bunker assault from Hacksaw Ridge. The first thing we did was set volume to -18 and watch it once through with the Danley in place.


We then swapped out the Danley for one of the Caps and watched it through again. I should note that when DD dropped these off a few weeks ago, he told me that one of them had the polarity reversed and I would need to unscrew the back plate, switch it around and re-mount it. At the time he pointed to the one with the issue, but since then these have been moved around and I had no idea which it was.


After watching the scene about halfway through on the first Cap, we paused and did a quick swap of the polarity on the speaker wires to see if this was the one that was wired wrong. After the swap the bass dropped off so we knew to swap that one back.


Next we stacked the second Cap on top of the first and hooked it up as well.

When you look at the back of both of the subs, the right binding post is positive and the left is negative. The right binding post should also be red and the left black. On one sub, the binding post is reversed and black is on the right and is positive and red is on the left and is negative. You can't just reverse the binding post. You also need to reverse the wiring. Alternatively, you can just connect your positive speaker cable to black and the negative cable to red.

That is what I thought you meant, but then I wasn't sure which was correct and which was wrong. I wound up taking off both sets of plates and checking the wires running to them. In both cases, the black internal wire was going to the black post and the red internal wire was going to the red post. Now that doesn't necessarily mean they are right, it is possible that Jeff wired the black and red incorrectly at the back of the driver, but that seems doubtful and I have no way to check that short of taking out the drivers.


What we did last night was wire up the first one normally, play it and listen to the level. Then swap polarity and listen again. The level audibly dropped off so we swapped it back to "normal".


Then we added in the second speaker, we assumed this was the wrongly wired one, so right at the start we set the red wire going to black and the black to the red post. We then watched some of the movie and again paid attention to the level of bass, we then paused the movie, swapped the wires around, and listened again. This time there was a noticeable INCREASE in bass, so we left it alone. That seems to mean that both of them are wired up correctly internally, but one of them simply has the entire plate flipped in a 180. If that explanation makes no sense, I'll show you next time you are over.


Now that you have me thinking about it, and it has been years since we wired up that Danley, it could be that one of the Danley sets of wires is reversed at the back of the amp. Those internal drivers are in a push/pull configuration right? I can't remember if I swapped polarity at the amp side or at the Speakon side.
