I've been checking temperatures with an IR thermometer see how the airflow for the rack is working. The Aragons are running very cool (only 10-15 degrees above ambient) The Sierra Audio amp and the Integra processor are quite a bit hotter than the Aragon amps. I ran the Aragon's stacked in my last theater and they were never more than mildly warm. My basement is pretty cold - the rack thermostat reads 66 or 67 all the time when nothing is on. The fans kick on at 71 degrees and I've never seen the temperature read higher than 75 on the rack thermostat. The Sierra amp was at 95 degrees after running for 3 hours last night at a pretty high volume.

Good luck man, heat is the biggest underestimation I made. Also remember once you get it out the rack and blow into the room you have to deal with it there too....... Unless your venting your rack to another room.

95 is warm but not screaming hot, but I would understand wanting it cooler. We spend all this money on components, it is nice to extend their lifespan as much as possible.

My equipment rack is outside the theater room so I do not need to worry about it heating the room. The Sierra amp runs cooler in the rack than it did in open air. The air circulation helps a lot.

I ended up getting the same rope light as you have and I have to ask... how the heck did you wrestle this thing into a straight line AND get the LEDs pointing down?

It's like fighting a snake.

I used these clips spaced about every 2 feet or so to hold the rope in place. It is a bit tough to twist the entire rope but you just have to work it a few feet at a time.



In my columns I used these for the rope light. These would work great in the soffit also. I would have used these but since I had the curve at the front just went with the clips.



The clips and channels are available from 1000 bulbs. Home depot also sells the channels next to the rope lighting.

Replacement screen still has not arrived yet. This is what I'm currently using.

Here it is. If anyone hasn't had the opportunity to explore What's Best Forum, it's certainly worthwhile.

I checked out the page you referenced. I agree that the white sheet looks pretty good - even not stretched. The big problem is finding a sheet big enough. If the sheet were bigger I would be enjoying it a lot more.

We used a huge king sized white bed sheet for nearly a year with our first projector in the first theater.......I was very impressed with the PQ even with a DARK brown wall behind the fairly transparent sheet it was great. I never stretched it whatsoever just tucked it into the drop ceiling in that room and voila. The only drawback with not stretching it was that near the bottom the sheet was "wavy" and motion scenes or crawlers like the bottom of ESPN would roll up and over the waves lol. You get used to it though.

Hey, you are going to love the Seymour screen when you get it. I just got mine mounted and for the first time watched something with my JVC RS45 and something besides a brown textured wall. You will love it.

Mini update - still waiting for the screen - I don't think the replacement has even been shipped yet. Getting really anxious to get the screen.

I also had an issue last week with the behringer amp running the subs. I noticed after playing for a while at high levels the subs started cutting out periodically for about 10 seconds then would come back on. I checked the temperature of the amp and it was pretty hot above the heatsink. I did the fan mod to the amp so I thought maybe it was not pushing enough air. I tried swapping the original fan back and still had the same issue. I ordered another amp and received it Thursday. When I started up the new amp, the fan did not come on at all. I thought maybe it had been re-designed to only come on when it got hot, but after 2 hours and getting pretty hot, the fan still did not kick on. I left the amp connected this weekend and a few times starting it up, the fan kicked on, so it appears to be an intermittent problem. The new amp stayed cool much longer than the old one - even without any fan running at all, so I think something is wrong with the old one other than the fan.

Luckily I ordered from Amazon and they shipped out a replacement right away. The new amp should be here today.

Which Beheinger amp? I have the embarrassingly-named iNuke 1000DSP and that fan is waaaaay too loud. I was planning on replacing the heat sinks and fan too.

The EP4000. With the fan mod it was pretty quiet. I think I'll leave the fan stock this time since my rack is outside the room. Its pretty loud with the stock fan, but either fan would be loud in my room. I can still hear the motor from the star ceiling a bit when nothing is playing.

Speaking of room noises - With the soundproofing in the room - any noise becomes audible because the noise floor is so low. As a side note, I've watched 4 movies in the theater so far - I've yet to come across any dialog or anything that I've struggled to understand - I also do not have the remote control sensor wired up yet and it has been fine not being able to adjust the volume. In my old theater I was always turning the volume up to hear quiet passages and then down again to keep from being blown out of the room when loud passages happen. I'm really happy with this aspect - no more pausing the movie when my wife asks "what did he say?"

My replacement ep4000 arrived. Fan appears to be working properly and the amp stays cool continuously. It is loud though - I had forgotten how loud the fan is because my other one with the mod was so quiet. It is tempting to do the fan mod again but I want to avoid any issues.

What fan did you end up using for your mod? Was it the Digikey part # P9739-ND? I will be following your setup and building an IB sub setup with one of these Behringer amps for power and will be replacing a similar CFM yet quieter fan to keep the rack noise to a minimum. Thanks!

Yes that is the fan I used - I looked at the invoice from 2009 and here is the description.

P9739-ND 8.68000 8.68 T
FAN 24VDC 1.30W 80MM FBA HYDRO

I also received an email from Digikey in July 2011 saying the part was obsolete.

You have purchased the following part number(s) from Digi-Key within the last two years. The manufacturer has announced this part(s) will become obsolete. Please click on the link below for more information on possible substitutes.


Manufacturer Details
NMB TECHNOLOGIES CORPORATION Description: FAN 24VDC 1.30W 80MM FBA HYDRO
Manufacturer Part Number: FBA08A24L1A
Digi-Key Part Number: P9739-ND

Not sure what people are using for a replacement if these are gone. They do not have the same airflow as the stock fan. My amp ran fine with the fan mod until recently.

Thanks for the info - I really appreciate it. I called Digikey and they recommended a substitute for the discontinued fan, Part # P14751-ND. It is 2 sones quieter, 2.1 CFM more air volume, 0.39 less watts in power consumption and double the rated hour life at 100,000 hours. Price is $8.15 for one, fyi. I'll post on how my swap-out goes. Here's a link to the new fan http://search.digikey.com/us/en/prod...751-ND/2615564

I am sure Behringer's fan was designed to be operational in 95 degree heat at some sort of summer music festival where the demands are large and constant in these extreme conditions. I opened a case up with the tech folks at Behringer regarding cooling options under residential loads in a climate-controlled environment just for kicks...

Plenty of people have done the fan mod with no issues. I'm just a little reluctant to void the warranty right now.

I don't blame you one bit, especially since you have a dedicated equipment room outside the theater. I just thought I would share the feedback I got from Digikey for future reference.

Keep up the great work on the theater...easily one of my favorite construction threads.

Still have not received my screen yet and I don't think its even been shipped. I'm starting to get a bit impatient with the time this is taking. The whole reason I bought the screen was because it was reasonably priced and I thought it would save me time.

Its been nearly 4 months since I ordered the screen. The majority of that time has been waiting for material from Seymour. I wish I would have ordered the fabric much earlier in my build and just put together my own screen.

Making me rethink waiting to order the screen. May have to set up the projector temporarily to make sure the screen size I want works with the projector location. Sorry to hear about your delay. Looking forward to seeing your completed room.

Wow, I was getting impatient waiting just over one month. When I picked up my screen material from Seymour 3 weeks ago, there was a full roll of the centerstage XD (if thats what you were getting).

I actually received my frame from Jamestown yesterday, but I bought the frame only - I plan on installing the screen myself. Best of luck getting the screen soon!

I think that it took almost 2 weeks for me to get a "straight cut" of Seymour XD from him. No frame, no rivets, just cut. That was after being told on a Saturday that it would ship that Monday (2 days later)... Love the product in the end though.

I still can't believe you don't have it. Has he said if he's having sourcing problems for the material or is something going on with his personal life? Chris is a great guy, I see him all the time at CES and it blows my mind that it's been 4 months...

almost 3 months waiting for the Seymour material the first time, then shipped the wrong size screen, now waiting again.
