Second box ready for primer. I was not planning on building the second sub quite so quick, but when Parts Express dropped the price on the UM18-22 $50, I jumped on it.

This will give me nearly wall to wall subs in the back of the room.

You can never have too much bass

Will now have nine 18's in my room.

Obviously you have never been to Burning Man. I've felt my teeth rattle almost out of my head at 3am in bed from vibrations coming through the ground ( and thru an air mattress ) from bass coming from " mutant vehicles " driving by. :-[:-[

2nd UM18-22 just arrived and box is almost ready. Primed and sanded. Just need finish coats applied. Will do that tonight.

Looking good. Mike, quick question. How much did you invest in all of the tools to build your own subwoofers? I assume the ROI is there in the long run, especially if you build more than one. Just curious.

you really dont need much as far as tools....have HD cut the wood...get some cheap clamps from Harbor freight...and a router....

my 4 subs blow away anything you can buy for a HUGE fraction of the price...I think for my 4 18"'s WITH amps....i was all in for 1400$  cant even get 1 commercial 18" sub for that
go for it!

You do want a DSP amp or a miniDSP, so that you can apply PEQ to the signal chain and if ported, protect the driver with a high pass filter.

Finished my second sub last week and pulled an additional run of speaker wire from mechanical room to HT. All six subs in place now. I still have not calibrated the subs, but I definitely have more low end bass, replacing the two 12's with 18's.

Spent Saturday adding additional connections to my MiniDSP 10x10HD and recalibrating my subs. Have everything dialed in pretty good right now.

Now that I am not using a horizontal expansion lens, switched to DCR, I need to switch out my screen. My current screen is a 116" diagonal 2.40 Prismasonic curved screen with powered side masking. Screen has DreamScreen V6 fabric. 

Since I want/need:

Flat scope screen
Woven AT fabric
Powered horizontal masking

I am going with Screen Excellence L-110 with upgraded motor and IR control. This will get me programed intermediate stops. http://www.seymourscreenexcellence.com/trim.php

The TRIM screen is great !

In all the videos I've seen the masking fabric appear to be a little too transparent for my liking. Since most of these videos are shot in a very bright environment (eg trade show), will be interested to hear how satisfied you are with it?  I know there will be "black" bars from the image but even a small amount of visible overscan would drive me nuts!

It can't be worse than the black masking on my Stewart electric screens !

I have been using a powered masking screen for many years. Problem is my current screen is curved and now I need a flat screen. I use a scope screen and an A-lens. The only thing I am masking is unused screen. So it looks black to me.

Looking at new atmos speakers, because mine are too big to be able to aim them correctly, due to my 8' ceiling. I currently have JBL 8340's on my ceiling. I looked at the JBL Control 328C, but decided if I was going to redo my atmos speakers, I was going to go with something that I could aim. 

So I am going to use ceiling mount brackets on four Volt 8's. I found a bracket that is heavy duty enough to work. Looks like the only weak link on the speaker bracket is the small surface where it connects to the ceiling. I will need to add a large washer to spread the load out on the drywall, otherwise it will crush the drywall over time. Have a truss I can hit for the front two speakers and will have to add wood blocking for the back two.

Volt 8: https://www.diysoundgroup.com/home-theater-speaker-kits/home-theater-series/volt/volt-8-ported-combo.html

Will mount the Volt 8's sideways. That way they only stick down about 12". That leaves me with about 7' of head clearance under the front two speakers.
