How does one perform the loop back on all the gear? This is a must for me. I want to know what is making my graphs drop at 5.5 hz! BTW, I just put the clone back in and bridged it with a one Channel 6 ohm load and you can really feel the difference in power! The one clone drives all my 13's which are 83 or 86 dBs sensitive each. I know you guys think that because they have a big surround they are not good but this system floors the 18's I had and the dual DTS10's. The 18's had more Midbass though but it was extra headroom anyways. I just watched HTTYD at reference and the subs 10 dBs hot with no problems. I also watched TDKR and man is that movie recorded loud! I thought the bass was much better the second time around. It hits very hard even though not deep. The beginning was demo material.

Thought I'd give an update - still LOVE this setup. Been experimenting with placement of the back subs a bit still trying to decide on the best locations for them. I'm in the process of building an AT screen and may reconstruct some boxes for the front of the room after I'm done.

I've had the minidsp out of the chain for a while now and even with just Audyssey for processing, they rock. When I put it back, I'd like to build an enclosure for the minidsp to tidy things up a bit. Not a big fan of wires hanging out of the Pheonix block, you know?

Andrew,

How big of an AT screen are you going with?

130" in 16:9, using Seymour XD fabric. Frame is done and wrapped in triple black Fidello fabric. The grommets are installed in the screen material. I'll finalize the details on the frame for the wall next week after this weekend's GTG. I'll be sitting 14-15' back once the wall is built out. I can't wait!

Awesome. I'm finishing up a 125" 2.35 this week as well. I didn't go grommet; just decided to staple directly to my frame. Interested in seeing some pics of yours when done for sure.

I went back and forth for too damn long about the attachment/tensioning method. I figured I'd give the grommets a shot as it seemed like a neat setup. My hands were numb after hammering out 64 1/2" grommets though. smile.gif

A few shots so far:

Oh yeah, I had the minidsp around from my Captivator days. Using a 2s4 balanced in a "box." I wish I had bought the unboxed version and simply bought a chassis for it. You wound up building something similar, right? Did you use a 1RU case?

Yeah, it should be pretty nuts. I have a 100" version of this screen now and have for ....yeesh, about 4 years now. smile.gif I should have just gone 130" from the start but I wasn't sure. Putting in an AT screen was one of the best things I've ever done to my HT system. Right up there with just having real digital surround sound and maybe a nice subwoofer.

Funny enough my original order for my screen last summer was 130", but in non AT. I downsized it to 120" to free up some room for speakers/subs on either side. Wish I had known what I do now when I placed the order since I would have saved $$$ and either built my own right away or just added the Seymour fabric to my Jamestown order.

Also experimenting with a set of Yorkville U215s I picked up last weekend. Man, these things can get DOWN! biggrin.gif

This is hilarous. I just ordered 130" of XD material 2 weeks ago,however I am going to attempt using the stewart frame I already have and install snaps on the XD material so it just snaps right in!!! haha. I am really stoked about getting it up, as the XD appears to be much brigher than the firehawk and I am truly interested in the woven vs. perf debate and making my own observations there. A 5 month old puppy still keeps getting in the way of laying the screen down and getting to this however...haha

Great minds.....biggrin.gif

Did you order the sample of XD? I went with the tilted cut even though I didn't have any negative effects with the straight sample. For me, the texture of the screen is not visible unless you're standing right on top of it.

yep went tilted, and from what I gathered, the only reason to use the flat cut is if they don't have enough material to cut it diagonal for you, but who knows. Using the sample I can definitely see a benefit from my LP where sometimes I can still see the perfs on the firehawk, but only when it is like scrolling text or something.

There really is no reason to go tilted with these newer projectors. I was using the original XD material a few years back with a 720p projector and the moire was noticeable. When I upgraded to 1080p there was no issue. Chris says he cuts them all with the 20d tilt though just to be safe, unless it's too big to not be able to.

If anyone wants a great deal on some BNIB XD screen I have some laying around. Jake's been rubbing off on me and a week after I ordered my 115" piece, I realized it wasn't overkill enough and had to move up to a 125" size. cool.gif

Very cool with the screen! I haven't looked at screens in forever but recently was thinking about it for the basement. Do you have a build thread for your screen or where'd you get the info?

Skeeter, I will have one up whenever I do mine, but the more important info will be in my measurement thread regarding the response between micro-perf vs. the woven stuff. Also, a DIY screen such as I am doing only really works if you already have some sort of Stewart frame which most people don't use any other fabric other than Stewart's in the first place. I got a heck of a deal on the firehawk so I just want to give some woven material a shot and see what happens for the sound aspect of it biggrin.gif

Scott - I will have a build thread up soon with details. I've kind of collected info from a bunch of threads on here as well as Seymour's site. The hardest part is deciding what you want to do and how to do it - so many options!

Beast - tuxedocivic has a great thread in the DIY screen section with measurements of many types of materials. Definitely worth checking out.

Rilla, I just re-read the entire thread and you did a great job on both the build and the documentation. One question I have is the volume of the HO driver; is the .45 for one or two (since you have dual opposed build I wanted to ask). I am thinking of building 4 3.5 cu ft enclosures for my basement, not dual opposed for placement flexibility.

Hope to drop by and hear your system next Fall when I'm back to living in Maryland.

Thanks! .45 is a good estimate for a pair of these drivers. 3.5 cubes works out really well with these drivers. You're welcome to come by anytime!

Yo. Did you put any poly in these boxes? I'm to that point and gonna line mine with 1" batting but can't decide if I want to mess with any extra. I'm at 7.5 ft^3 before drivers but I'm not reading 32 pages to see where you ended up, and can't remember. I think my q was .76 when I modeled it.

^ Thanks Adam.

Another note - I've been experimenting alot with crossover points and phase with these guys. IMO the 150hz cross sounds (and measures) great, especially for music. I'm having a heck of a time integrating with lower than a 80hz crossover to my current mains when attempting to keep the L/R full range as much as possible.

are you running pure LFE or the LFE+Main setting on the AVR? the latter may get you better integration as i believe it lets you keep your speakers set to large while sending the LFE to the sub and the sub only picks up below the xover

Yup - tried that as well as experimenting with phase, distance/delay on front and rear subs, 40-150 crossover points for main/sub, etc. I've got it dialed in pretty good now and played more with speaker placement. I'm continuing to run without a center and it sounds awesome!

I had the same experience with my Cornscalas. It just sounded better crossed over to the subs. I tried it with lfe+mains and it was the same outcome. That's one reason I sold the Cornscalas.

are you running pure LFE or the LFE+Main setting on the AVR? the latter may get you better integration as i believe it lets you keep your speakers set to large while sending the LFE to the sub and the sub only picks up below the xover

LFE+Main means redirected bass from center channel and surrounds is copied to the mains as well as the subwoofer depending upon where you set the xo point. LFE is sent only to the sub. IOW mains are considered as large that perform sub duties minus the LFE part.......Not a good thing IMO for movies unless of course you have very very capable mains that can dig down to sub 20hz region with authority.

Ummm, wha??

The DIY sub company offers many products, but in the end you are never really sure which one they are going to ship to you. I wouldn't buy from the DIY Sub Company. Way too risky?

Expanding on the original topic of this thread, I'm in the process of constructing two 22" cube boxes for the living room to replace my recently sold Epik Empires. Each will house a single 18" SI D2 driver, powered by an EP4000 for now. I'm currently in the process of 'selling' the idea of adding two additional boxes/drivers (for a total of four) to the rear of the room to the wife. biggrin.gif In which case I'd be using one channel of my spare clone amp or the XLS5000 to power the quad 18s. Room size is 19x20 with high ceilings - and of course sitting on a suspended floor which makes for some real fun. biggrin.gif I get some decent room gain in there but will still need some EQ.

Build Notes: This was my first time cutting oversized panels (1/16th to 1/8th) for the top and front baffle which kind of seems like a waste considering I took a good deal of care to make sure all the cuts were spot on. The bracing was kind of a PITA to line up everything but appears to be very rigid. The one annoying thing about the centerline vertical brace is that I cannot place my connectors in the middle of the box. I may add in one more horizontal brace on each as well. I cut both outer baffles at once which made things very easy in terms of alignment. I'm excited about having speakon connectors on these vs. the bananas on my original dayton boxes. I may be updating the original boxes to use these as well.

Some box specs:
  • 22" Cube for just about 4.25 cubes net including driver displacement and bracing
  • 7 Ply 3/4" Birch plywood construction
  • Triple front baffle to allow for grill use with the large surround
  • Cross style horizontal and vertical bracing
  • Recessed speakon connector
  • Duratex finish
  • Magnetic based grills based on original design but in 1/2" thickness. Will also experiment with splining method of attaching grill cloth




Before outer baffles are added.


The pics are slightly out of date but more to come. I currently have the front baffles glued on and will be flush trimming the boxes tomorrow night. Should be prepping and paint this weekend. Going to do a duratex finish on these guys as well. cool.gif
