I have a little bit of trim to do around my bar at the back. Some sanding and touchup here and there. I need to build fabric panels to cover my surrounds. I want to add some decorative touches to my columns. I need to get my screen down and rearrange my LCR (they're still upside down). I need to put up my treatments.

The theater won't make any progress any time soon, though. I need to get the rest of my basement finished first.

Like the previous post says, I've got a few things to finish up in my theater, and I have to get the rest of my basement finished up before that will happen. So like any sane person would do, I'm adding another project instead.



I've wanted one of these cars since I was 14, and I finally indulged myself. She's got a lot that I'm planning to do, but the body is straight. All the rust in the quarters/fenders/doors has been repaired. So it's the fun stuff like suspension/motor/trans that's left to do!

In basement news, despite feeling like I'd been hit by a truck.... loaded with pollen..... and pepper....... and maybe fiberglass insulation........... and possibly cotton....... I did make some basement progress last weekend. I'd say I'm about 90% done with my electrical rough-in. I've got all my can lights hung, bathroom vent fan, and cut-in some remodel cans and fished the wire. I've even pulled the wire for the bedroom receptacles. Another day or two to work on it and I should be ready for plumbing rough-in and drywall. I want to get the drywall finished and painted before I have the floors stained

So is that we are now calling midlife crises...."projects"???

Sweet ride. Will definitely have to plan my trip to 'bama when the weather is good...and the car is functioning (i.e. not mid-engine rebuild!)!

Hahaha!!! Guilty as charged!

If you're going to plan a trip to 'Bama, I'd recommend waiting until the weather is cooler. This time of year it's a crap shoot as to whether you'll be running the heater or begging your AC to work better. Sometimes both before noon

Nice Camaro! I've wanted a '70 Chevelle SS (LS6 of course) forever but lately I've been thinking an older pick-up truck would be nice too.

Yep. We all have our poison. It's sad that there are only a handful of cars being built these days with real character - and all cost more than I can afford. But there are lots of cars from the 50s and 60s that still turn heads.

Man I would I love to restore an old column shift pick up like my grandpa used to drive. His smelled like whiskey and cigarettes though.

There's been progress!!!! I'm working on finishing the rest of my basement, and I needed to install a smoke alarm in the new bedroom. I took the opportunity to put an alarm in the theater as well.

Yep... That's the progress

The car is just sitting there. I take it out for a cruise every now and again, but I've been waiting 2 months for suspension parts. These cars had pretty poor suspension geometry to begin with, so I want to get that sorted to make it more fun to drive. Still looking at a few more weeks before I have all the parts in hand. Everything is back ordered at the moment.

I did have my first electrical inspection for the rest of my basement last week. There are a few things to sort out that really boil down to what level of finish the inspector wanted to see for each inspection. Waiting on plumbing now, and then I can do my insulation before drywall. That project is moving slow as well. Construction has gone crazy around here, so it's tough to find subs for these odds and ends jobs.

You should just dig a hole in the back yard, get one of those quick starter fireplace logs on the bottom, with some wood logs on top of it. Light it. Get a chair, and a beer... and just sit there and throw 20$ bills into the fire. Do it a couple times a week after work as you relax. It's cheaper and easier than rebuilding a muscle car, or building a theater.

Yessir. That is correct. I haven't had time or the motivation to do much in the basement lately. Too much life in the way

So we decided to host a Star Wars summer series for my oldest son's school friends (1st grade). That may be enough motivation to finish up those final odds and ends I've been meaning to do. Though if I'm honest I'll be doing good to get all the popcorn out from under the chairs before the first movie (Episode IV of course) on the 10th. I did go ahead and order a replacement lamp and the two additional Buttkickers I need. Maybe I'll at least get that done before the 10th :-)

I think this will be fun for the kids. Though I'm not sure how much they'll actually watch the movie.

I thought I would post this here for completeness as well in my other thread.

I finally took the time to take my screen down so that I could add the first step of my treatments. I did the usual front wall double layer of Linacoustic with a layer of 6 mil plastic between (I actually did two 3 mil because it was easier to deal with folded over). On the room-facing surface of the subs I added a single layer of Linacoustic and also put some scraps on the horizontal surfaces that my speakers sit on. You can see most of that in the picture, but it's hard to make out the front wall is also covered. I also took the opportunity to put a little black paint on my LCR drivers. There was a bit of the machined metal showing around the driver, and it would shine through the screen on some bright scenes.

My room design actually calls for a baffle wall with the large space behind used as a bass trap. But we're taking baby steps here. Here's a before and after of the room for reference.

Before

After


Here are the before and after measurements of the center channel. I had to shift the measurements to roughly align. REW + Mac can be a little finicky, and the volume wanted to move around between runs for some reason.


I didn't make much effort to verify the mic was in the exact same spot for these two measurements. At some point, the front will end up with a baffle wall, but I was curious to see what the "standard" double layer Linacoustic approach does. Aside from the Peak and dip between 80 and just over 100 Hz, it's tough for me to say there's really any improvement. I need to run the rest of my sweeps on the surrounds, though. I suppose I might see some changes due to the rear surrounds pointing at the front wall, but they are a LONG way away.

I'm not sure I can really tell any difference in the sound. When I did my first listening test, I was initially very impressed. Then I realized my DDRC-88A was bypassed (no dirac live calibration), which for my room just makes the sound "brighter" and a 3 dB louder. And we all know the first rule of hifi, louder sounds better. Once I took that into account, A/B with and without my existing correction, I can't say I could tell much difference.

I'm beginning to think I'm tone deaf

Did you get the - whadayacallit - the time data, ETC? out of the sweeps? I think most of what would be improved by the linacoustic (same as what I did) would be in the diffraction.

It's scary how much stuff I've completely forgotten after taking a hiatus from my theater building. You're absolutely right, HF.

Here's the impulse response for my room. I couldn't get the graphs to overlay for some reason. Two plots, one before treatment, one after in that order. No smoothing applied.

No absorption



I don't see much improvement here, either. There's a peak at around 1.09 ms (1.2') that actually appears stronger in the "treated" plot. I'm guessing it's actually in both, just minor differences in positioning causing it to look less pronounced in the pre-treatment plot.

That said, I'm guessing the 1.2' reflection is from the soffit above my screen. Unfortunately, if it is the soffit, there's really not much to be done about it. I guess I could angle my mains down a bit. We'll see if it persists before making any changes to main positioning. It's a PAIN to get my screen down and moved.

The next peak is at just shy of 2.2 ms (~2.5') - again in both plots, which I would assume is the ceiling itself. Ceiling treatments should help with that.


All that said, I still don't see much improvement from the treatments behind the screen.

Thoughts?

Alright, I hung some of my treatments yesterday. Quadfusors then slat diffusors (includes some absorption).

Treatments are the same for both walls.

Bare wall before


Quadfusors


Before slat diffusors. Nyal asked that I know show them, but you can get an idea of where they go based on the framing.



Here's measurements before, with quadfusors, and then with the slat diffusors. Not much to see, I'm planning to cover the measurements in more detail in my other thread (see sig).

Did I not post a pic of the room with my fabric panels in place? How did I forget to do that. They've been up forever.... Well... They're not up now, but that's because I've been adding treatments.

I have no skin in the game with this, but was curious as to the thought process which manifested in these being installed in this fashion, complete with surrounding box which is always the #1 speaker no-no.

Excellent observations!

I originally wanted columns, but had ruled them out at one point and tried to mount the surrounds on the wall. However, I tried a pivoting TV mount, but couldn't get them to hold their position (speakers are pretty heavy). The speakers needed to be angled toward the seating position rather than flat against the wall to put the listeners on-axis rather than relying on the off-axis response of the speakers. So I went back to a column design (a shelf) that lets me point the speakers towards the seating. The plan is to add an AT cover for the front along with some decorative flourishes like corbels and trim to the columns. I agree that putting them like this is generally a no-no, but a compromise had to be made. Fortunately, they're front ported, so that at least helps a bit.

Just to the left of this image is another row of surround speakers for the 2nd row. You can actually see a bit of the column on the left of the image you quoted. So each row has a set of surrounds. They do look low, but are actually 2' above seated ear height. The original design was higher, but was moved down once Nyal had a chance to look at things. This is a balance to get the speakers above the listener to maintain line-of-site, but keep them low enough to provide separation in the event I add ATMOS top speakers. Interestingly enough, surround presentation is a little better from the 2nd row.

Finally, the VOLT speaker has a slanted front to help angle the speaker towards the listener. Again, trying to put the MLP in the on-axis response of the speaker. For an installation with the speakers at 90-95 degrees, they could be hung on the wall and the speaker would naturally point slightly downwards toward the listener. Preventing the need for leaning the speaker down.
