I guess I should formally apologize to Zane, I did a little bit of construction and demo this week. I made 6 boxes. Brad nails with silicone.. Had sealing issues broke relatively easy with just my foot. Just glue... Held up well, and did break at the joints with enough blunt force. Just screws and silicone, had very minor sealing issues, and broke at the joints (around the mdf, the screws were intact) Brad nails, wood glue and silicone, worked very well, but the nail heads pulled through in demolition, meaning that it was a nail failure. Woodglue, screws and silicone was as expected the best of the builds. My final box was the only non 10"x10"x10" box. It was a double baffled with 45* joints only using glue.. When destroyed it proved to be as hardy as the single baffled screw/glue box but unlike the screw/glue box the joints failed before the mdf started flaking. I used titebond II, 1 5/8 coarse threaded screws, and 1.5" nails. I tested for sealing by drilling a 1" hole in the box and attaching a shop vac, using the blowing side I wet the joints with soapy water (the same method used for tires and hoses). I would have had pics but my camera is in Italy right now.... I did this because I had some thinking to do. Last season, my spl boxes were all built using pre-drilled and countersunk screws, and titebond II, I never had a joint failure. I did have a baffle break in one of my boxes, and the joints were completely intact.

Not a big fan of beer, Why are you awake denim??? Slow night at work, working on some math for my next car audio build... Need to decide on a couple more product choices still. Mostly dealing with wiring, sound deadening, processing and budget goals (which i'll probably double at least)

Exactly, almost. Lower octane fuel burns easier. Ironically enough we all think that 93 octane is more potent, it's less potent. Just like poorly designed cold air intakes, or just using a k&n intake can also lower your fuel economy if the air passing the maf is warmer. More air= more fuel injected. On anoter separate note, cold air intakes, don't mean your engine is actually pumping more air, as when the cylinder is moving downwards and the intake valve is open, the engine is only taking in as much air as cylinder displaces (plus a little more from atmospheric pressure.) *Not including forced induction engines*

off to work, i'll be back on ~11pm eastern, its when my job slows down.

Use division, If you are running 3 power, use 3 160 amp fuses.

by my previous post, you can pm me details about that table, please

Oh my... Details ? It's a VPI HW-19jr, upgraded armboard, counterweight, record clamp, dustcover and manual included though they're not in that pic. Absolutely no marks on it, just looks dusty with the light. I'd be a little scared of shipping it that distance, though... Shipping would probably be too risky Looks nice... Too bad shipping companies hate me. lol

143.6 on music is a great score

looks good

slow night in the hop

and here are the rest of the pics of my first system. http://www.cardomain.com/ride/2325907/2

D@mn That is clean. Too bad that car met a tree. Ironically enough, today is the day I finally finished the loan payments for that system and i'm posting about that car.

Mike 1? guessing that was meant for someone else, i'll be back after the movies, later hop.

you can see some basic ones here: http://audioobsessions.com/Gallery/

That was my spare tire wheel install... For basic ones, i'll find some pics.

ohh, and finally running optical audio from my xbox 360... can definitely hear the difference

I'm currently working on some details for another sq system. yay.

i love their old stuff from around 2005.

This will definitely be going in my next sq build.

They actually sound pretty good, I used to have an extreme spare tire well install... Hold on, and i'll find some pics.

also powermaster and ohio generators

Uggh...... Now I remember why I stopped going to forums.............. Obviously you missed the material and observational learning part on the job sites. That or relating whats learned to similar projects. Building a house is a thousand times more complex than a simple subwoofer box. Yet both involve nails, screws, and glue. Of those 3 general materials, I've seen litterally thousands of houses, buildings, complexes, stores, where nails and glue have failed. (And created quite a headache for repairs) Screws on the other hand, even rusted from weather, 98% of the time were still fastened in their original loactions, and continuing to serve their intended purpose. Now the real funny thing........ Of your (emphasized) "hundreds" of destroyed MDF Enclosures where the glue joint has held and the wood has broke; I can also point out the (emphasized) "thousands" of times that I've yet to see a screw fail before the wood breaks in MDF, HDF, PLY, CDX, OSB, Particle, etc...... If the wood glue alone works for you, so be it. Your general statement of wood glue being stronger than wood screws is where I have the problem. On that note, I'm done with this one..................... I agree that house construction vs. sub box construction is different. I stand corrected as I worded what I was trying to say incorrectly. The woodscrews would not fail, it would have been the mdf around them. I was trying to point out that generally the weakest part of the joint in 3/4" mdf is around where the screws are. Simply b/c MDF is rather fragile like particle board, it peels apart. I would also clarify that my jobsite experience is in demolition, and pavement/sidewalks as I do it as a hobby for my grandfathers company when he needs an extra laborer. I have never constructed a house, or done extensive carpentry work in any job thus far.

night

Oh, and I'll add that I have done butt joints with just glue and no nails or wood screws without premature failures. Oh and I've been on job sites my entire life... Funny thing is, it taught me nothing about subwoofer box construction.

Pretty general statement there isn't it? I have over 14 years experience in the construction industry, and I'd typically put more faith in the wood screw than the wood glue. I've seen wood glue seams break infinitely more times than wood screws pulling loose. And I've destroyed hundreds, let me emphasize, hundreds of MDF boxes in my career and I have yet to see the wood glue joint break before the mdf itself.
