completing subwoofer

now that the garage is back to normal i was able to finish what was left on subwoofer. plate amp arrived 3 weeks earlier so i have had all the parts necessary for a while. first thing i did was i mounted woofer in place and added spikes.

amp wired to the driver

now it is polyfill time. i got bag from wall marts hobby section. enclosure needs to be stuffed with it. the good amount is 1 to 1.5 pound per cubic foot. stuffing too dense would have exactly opposite effect on enclosure and made it smaller. the way this works is that the air inside  moved by cone displacement wiggles poly fill fibers. their movements warm up the air inside the enclosure. warm air is less dense than cold air which makes the volume of the enclosure bigger than it really is.

and the finished product. i still need to finish cover frame and apply speaker cloth.

 finally done, all complete with cloth cover

almost done

garage wall

we decided to install pegboard instead of gyp board. it will be easy and faster. for ceiling we rented drywall lift. 

after whole weekend of work we finally finished ceiling, south and west wall. we still need to install shelves next weekend. we hope garage will be done next weekend.

garage insulation

we decided to start new project. we would like to finish and insulate our unfinished garage. we must do it by individual walls because we don't have space where to store all things.

we started with west wall and we used R13 insulation

and after a couple of hours one wall is insulated

insulation done

enclosure finishing

from now on, i am going to quite improvise. i am going for glossy white finish. i could have it professionally done at any body shop but the price is quite outrageous and this is diy project anyways. i did some research online to see how people are tacking this kind of project. i could rent spray gun and attempt to do it same way as it would be done in body shop. this however would still cost too much for renting equipment and material itself. so, i am going to use what is relatively cheap and readily available.

step 1:
i purchased BIN, shellac based wood primer, at Home Depot. it is supposed to seal porosity and have good cover ability. i did two coats today.

followed with speckling and sanding with 220 grit, than another round of 2 coats of primer and speckling.
after everything sanded smooth i did 2 coats of krylon white gloss.

than i wet sanded with 1500 grit. circular, horizontal, vertical, diagonal.  lots of elbow grease used.

finally i waxed and buffed the surface to the shine i am happy with.
