Steve's home made jasper jig will work fine - it just like what I did, but there are two "gotchas" in using any circle jig that haven't come up.

1. Try out a scrap first. No matter how carefully you measure and think it through, there's a high probability that the size is not what you expect.

2. When the router completes the circle, it WILL pull and gouge your baffle. You have two options: stop short and finish with a jigsaw, or secure both pieces (the baffle and the scrap) to something stable - either a sacrificial layer or a series of scraps like I used.

Don't let me take credit for this idea, I'm sure it's well known to experienced woodworkers - I got it from cowger's build.

Mulling over........what to cut into and tear out.......

TJI at 16 inch on center joist to cut........1-1/8 plywood subfloor......3/8 inch Serenity Mat.....3/4 plywood + Green Glue + 3/4 inch plywood.........then 2 X 12 joist plus three more layers of 3/4 inch plywood and then pad and carpet..........well it would take a Herculean feat to accomplish......certainly doable!!!!! eek.gifeek.gifeek.gif

.

With a plunge router, leave a few small sections where you almost, but not quite go through. This way, all breakout is tiny and on the inside (if it breaks) and otherwise you can saw it and the saw marks are still on the inside..

That's weird. I always cut mine on a sacrificial scrap and I've never had a problem chewing up my piece after a complete cut. A lot of this has to do with router speed and bit quality. I let the router do the work and don't put any more "english" on it than needed.

Thanks Fred.......

The baffle cuts don't have to be pretty since cabs will be placed behind screen. Only real issue is, "Will they seal completely?"

I have lots of neoprene rolls left from column rattle elimination procedures. Will use what's left on four baffles.

Extended 2nd row seating and moved sub directly underneath........rotated driver 180 degrees so they fire directly into rear wall. Rotated cabs so height was 20 inches so now cabs are completely out of view!

Walking on 2nd row aisle......subs can't be seen and blend into seating......black cabs work as columns are now in full view including column base which was obscured from view with other sub arrangement.

Thanks for firing my synapsises!





Isnt the door in that back corner? As in, wont everyone be walking in past that behind the seat section the boxes sit in?

You got a nice room. Go the extra mile and place those boxes so you can build out the woodwork to cover the boxes. Ill show you my sonotube when youre here. You will see how short and compact it is, and how nice you could center it up and cover it with that nice millwork.

Number 1 kicked my ass for a while, then I found a series of videos on youtube that explain how to measure down to a 32nd and get precise results every time. It works...... The links are in my sono build.

I never had a problem with number 2. I used some scrap mdf as a table, and put a piece of rubber shelf liner on it. Never hd an issue.

No, door is in front of room...........on left hand side. Walk in and first row is right there.

No one has access to back area.......when you walk up stairs to second level, can't see subs now.







Most people design their home with a theater room.........on the other hand,

I had a theater room designed with a house. The room was designed professionally first..........once that was done, then home was designed around theater room. I can assure you, room has been designed perfectly for intent.

Some people may think that's backwards, but it works for my wife and I. wink.gif

Yeah............I absolutely ran full circle!  ;)

 

Was going to go 2 SI-24's up front and two LMS-U's or UXL's in back but got cold, cold feet on SI-24's and wont go into details why.

 

Last Sunday, someone posted in group buy for UXL's wanting someone to takeover financial responsibility for two of his UXL's and I jumped on it.  About an hour later, two more became available via pm, so I jumped on it with no questions asked. Before I knew it..............I had my four drivers.

 

What I find interesting is the next day I was planning on ordering four LMS-U's  from Parts-Express but then those bloody first two UXL's became available! I frantically pm-ed everyone I knew at AVS about their experiences with both the UXL and Ultras.  With only supplying each driver with 2000 watts in 4 ohm's, I decided UXL's would be better for my application and theater room.  

 

I'm actually relieved................and feel I made the best decision for me under the circumstances.  BTW, I have to pay for upgrading my projector this month, and in a few months I have to pay for my Trinnov TEQ-12.............so the UXL's help in that regard!!!!  ;)

It's nice to see you finally made up your mind. tongue.gif

All of your choices were excellent; I think you'll be really happy with those UXL's. Congrats.

Thanks..................

 

You'd be surprised how much your suggestions influenced my decision...;)..................of course, I also pestered the living daylights out of those who have experienced both Ultra's and UXL's.

 

If those UXL's would have come to me 24 hours later, I'd be on the hook for four Ultra's which isn't a bad thing.  Saved some cash as the theater room is a money pit!!  This month projector............................June will be my Trinnov unit!  Believe me, I heard a dedicated theater room using the same speakers I have but with Trinnov for eq and the word STUNNING can't describe in words what I heard!   The Trinnov unit has me PUMPED!!!

ADA unit? Why not look at the stand alone Trinnov units and expand it to the number of discrete channels you need??

post #388 of 408
If you have the funds, I can firmly say it is better to get what you truly want the FIRST time. Sometimes trying to save money will cost you more in the long run. If the LMS is what you wanted originally I would go for it and be done with it.

I can tell you from experience buying and selling drivers can be a HUGE pain and you will lose boatloads of money and time doing so.

Not sure what issues you are concerned with, but I had one of those 24's for a long weekend on loan from SI and the build quality on that woofer was top-notch. I wouldn't hesitate to pop a few in my space if I still had room to do so biggrin.gif

I'm going out on a limb, but I'm thinking the concern wasn't in regards to the driver.

I want to implement one just to be able to say I have a 24" woofer. biggrin.gif
