    Worst Sub Box Ever?

    Man, and I thought my temporary IB setup was bad (double stacked birch plywood screwed under floor under an unused return vent, wood grate over the whole mess) I guess it works fine and is stealth as can be, it's just that it's so crude. Compared to this monstrosity, it's aged wine and fine...

    IB into crawlspace?

    I want to set up a dual Dayton 15" DVC IB sub in my living room with the subs in the floor into my crawl space. It's a huge crawl space, being ranging from 3 to 5 feet in height. I am concerned about dirt or insects getting into the voice coil assembly (I ran into a million spiders when running...

    Need advice for Tempest in large room

    Fortunately I have movie night Mondays, basicly my neighborhood friends come over on Mondays and we watch a movie. He's been to a couple, this should encourage him to experience it versus be annoyed with it. As far as rattling stuff on his walls, it's a bachelor pad and he's in college...

    Need advice for Tempest in large room

    Cam, just thought I'd let you know that your posts have helped me decide on what I am getting. I've decided on a Tempest in a Adire ported enclosure with a Rythmic 250 amp. I was worried about 250 not cutting it appearantly it will :). My room is 16' x 10' that opens up into a slightly...

    finding the perfect ceiling bracket for a front projector

    My digicam sucks and we have no photo editing software here at work, so all I gould get is a very washed out picture. Normally, my living room has subdued lighting, so the block of wood looks decent, you can't see any wood grain or the layers of plywood. Bevelling the edges keeps it from looking...

    finding the perfect ceiling bracket for a front projector

    I tried for a long time to design an adjustable ceiling mount that allowed my projector to be taken down without too much trouble, and that didn't drop the projector off of the ceiling too much. My friend runs a machine shop, so fabrication wasn't too big of a deal, other than I didn't want to...

    Cartridge Laserdiscs?

    Cool! So this was essentially the Betamax of the LD world (well, Betamax with some serious issues. Also note: I'm not trying to start a flame war, I know a few veterans who are still mad about the whole Betamax thing :) ) That would explain why it seemed like it had visible groves as opposed to...

    Cartridge Laserdiscs?

    Today I picked up laserdisc copies of 2001: A Space Odyssey , Scarface, and Poltergeist, but they came in a weird cartridge. I'm a bit young to really know a whole lot about Laserdiscs, but all the ones I remember are like huge CD's, kinda silverish. These are approximately the same size, and...

    Digital Cable audio problems...HELP!!

    I work for a cable company (not TW), I think that it is odd that a) TW is having this sort of problem, especially in a big city, and b) they didn't at least _offer_ to have a repair tech come out and look at the problem (that's what our CSR's do once they've eliminated that it's not a problem...

    TL coffin sub...

    I'd have to agree with the others, stick with the drivers that are mentioned in this forum. TL's are cool though, and I think they are fun to play with (varying the amount of stuffing to tune it) I'd say go for it. The AQA box replica they have on www.t-linespeakers.org is a fairly...

    DIY Amplifier

    Stephen: Nice, I've been looking for a ready to go kit with some decent wattage behind it. When you refer to noise from a PC power supply, are you referring to electrical noise (that affects the amps performance/that you can hear through the speakers), or audible (not through the speakers) noise?

    Getting ready to build first sub - sonosub

    It's all calculated, I can't imagine doing this through trial and error. Basicly is a ratio between box volume, port size and port length. Here's the equation: * Lv = (23562.5*Dv^2*Np/(Fb^2*Vb))-(k*Dv) Where Dv = port diameter (cm) Fb = tuning frequency (Hz) Vb = net volume (litres)...

    Teach me about projector screens.

    Oohh.. I haven't thought of that... my projector is ceiling mounted (or will be once my friend is done making my ceiling mount) It is directly above the couch on at 8" ceiling... will that be bad if I go with a Dalite?

    Teach me about projector screens.

    Ahh... so a higher gain has a smaller viewing area? In a way it "focuses" the projected light (in a reflective sense) Is this why curved screens have insane gain values? Retroflective, like in safety tape, on runner's shoes or traffic signs? Interresting. Thanks, you've sparked my...

    Teach me about projector screens.

    Thank you for discouraging my purchase of a glass beaded screen. I suspected that there would be a texture to glass beaded screens, I figured that there had to be some major downside with a gain of 2.5 with no price difference. Ambient light isn't a problem whatsoever. I think I will mess around...

    DIY Masking System

    This is an excellent idea, why didn't I think of it before? Oh yeah, because this is an excellent idea. I can get an 80" wide Dalite 16:9 screen for $130, or an 80" 1:1 screen for $80, and mask as needed, then I'm not stuck in 16:9 (even though I only change to 4:3 when I play Splinter Cell on...

    SpongeBob BC

    I didn't catch the last Sponge Bob was it a new episode? I love Sponge Bob, we watch it every time it's on at work unless we're short staffed, like tonight and last night. (I work for the cable company, so we have TVs everywhere) I don't have any kids, it's just a good show.

    Teach me about projector screens.

    I am getting ready to buy a projector screen, but have some questions. I am running a Dell 2200MP projecting a 80" wide picture on a wall (so I can get a feel on what size/position feels best for veiwing). That seems to be a good comfortable size. I'm pretty happy with the brightness, but I feel...

    aligning projector to match screen..

    First thing you need to do is make sure that the projector is level and square to the screen. If the picture is trapezoid shaped then you can use the on your projector to fix the problem. Use that in combination to the zoom to try to correct the problem. If your projector does not have a...

    Cat 5 speaker cable..

    From rom what I've read/heard CAT5 (e for that matter) is regular old copper, it does not need to be OF or any standard of purity to be CAT5/CAT5e. But, IIRC, all CAT5 must be teflon insulated.

    $1k projector round-up

    Hmmm... I'm using the component out/stereo out/optic out HD pack with the component to VGA cable provided with the projector. The display mode indicator on my projector says 720x480p (I run widescreen most of the time) when the main dashboard comes up. And some times higher (even though the DLP...

    $1k projector round-up

    Can I put my 2 cents in? Good. I'm new to the HT scene and didn't have a too many chances to compare lowend projectors side by side, so take what I say with a grain of salt. It all started out with our 27" Magnavox that was going bad. (we got it second-hand for $35, I can't complain one bit)...

    "custom D-sub to component video cable"

    I have this same projector. I'm thrilled to death with it, considering how little I paid for it. It does suffer from the signs of a cheap DLP, slow color wheel, so you will see a rainbow effect on credits and really dark scenes. It drove me crazy the first week, now I don't even notice it. Back...

    port length questions. how to measure

    I'm going to be using PVC for a port, and it will need to have a 90 degree angle, how do I measure around the curve?
