With about a 1000 hours on my X1, the picture was getting dimmer and dimmer and the colors seemed very poor. I figured it was just the bulb getting old and getting dimmer, and I was just trying to throw to big a picture with this little low lumen projector. The picture was getting so bad that I...

So I want to a buy Mary Chapin Carpenters cd - but they are all "partial albums". there are no buttons to buy the entire album like on most other cds' I've seen. So you can buy partial albums or what?? Is this a bug in my windows software or do they do this on albums that have more than ten...

After 300 flawless hours of use, my projector's picture has turned green and posterized. First it started with a few pixels "here and there" only affecting grays, now its the entire screen. It looks like you looking through a green lens and the picture. This is on every input. Svideo, Interlaced...

Which of the current DVD's is the best for calibrating and digital FP, an X1 to be exact? I have Digital Video Essentials and while some of the test they have do help, I get the feeling that a disc geared more towards FP instead of tubes would be more helpful. I also know that some new disc...

I've got my my LAB horn subwoofer almost finished minus flare extensions and paint/finishing. here is a page with some construction pics on it. http://www.globalms.com/horn.htm I will add measurement graph as soon as I get a chance to make them properly. Construction of this box was more...

I remember seeing a couple links post here to sites for fixing room modes with large "tuned" tubes place stategically through out. In searching the archive, I could find only one which is now defunct and a headphone site. Any links to info on standing waves, room modes, and previously...

I bought one of the refurbed Pronto's from JR about 3 months ago. It's worked flawlessly for me until now. I cam home one day last weeka and it wouldn't light up. Dead batteies I figured, so I replaced them. No go. Double checke that I had them in right. No go. The mute and up volume...

I usually make all my speakers at my brothers woodworking/cabinet shop that is stock with all the tools I could ever want. But he lives a 1 1/2 hours away, and I'm getting tired of the drive. I really don't have the money or room in my garage to put a nice uni-saw table saw system for cutting...

While this probably belongs under "Bargain and coupons" forum, I think it fits in this one much better. Anyways while browsing the scratch and dent section at Parts Express I notice this subwoofer. I thought maybe someone here might be interested in it. A little to pricey for me. What...

I was just wondering if it is possible or feasible to make a filter of sorts to control the incoming signal to a Subwoofer plate amp so it will not clip. I know some regular amps have them built in and sometimes call them "clip-eliminators". And just getting a bigger amp won't do the trick...

I've just finished another sub. This one is a sealed tempest in a 130L box, with a 100 watt plate amp. I'm happy with the results but was wondering how variovents would affect the performance. Thanks

A customer of mine came in today with a piece of PVC pipe that was 16" in diameter. Maybe some of you have seen PVC this big, but I never have. The walls were 1/2" thick and he said that it also came in larger sizes. Price was about $10/ft. Any reason why this wouldn't work great as a...

I've just completed my latest sub. It uses a 15" Dayton DVC in a 6th order Bandpass(vented front box and vented rear box. The rear box is about 130L and tuned to 16 hz. The front box is 25L and tuned to 50 hz. I made the box to be used as( or at least look like) a coffee table. The outside...

I had a 8ft^3(220 liter) rectangular sub with a single shiva for about 6 months. Although I was I was happy with it, I wanted more. So i ordered another shiva and built a sonotube for two. My new shiva arrived so it was time to remove my old one. Took all 8 or 12 screws out of it. hmm...

From what I've read here Duvatyne would work great to mask off the grey letterbox bars on my FPTV LCD. Where would I get this? I'm not even sure how to pronounce it correctly. What would a good price be? Thanks

Not sure if this belongs in this section of the forum or not? But it is DIY. I'm moving my home entertainment system from the first floor to my basement. I call it an "entertainment system" because it isn't a true "home theater yet". I just bought a projector though, so I'm getting closer...

I just got finished with my dual Shiva Sonosub. It's 24" diameter and 7 feet tall. Volume is about 600L. My room is about 12' square, and because of the way the doorways on the room are, my listening position is in a corner, TV in opposite corner, and my sub is in the corner to my right(when...

This is kinda of a combo question. 1) When you look at X-max specs are they always one-way? 2) When you look at cone-excursion results in Lspcad are they referring to the one way Xmax or total movement which is always greater than 2x-Xmax( I think) Example I'm modeling a 6.5" driver that...

Is there any reason not to use angle iron as sub bracing?
