Pioneer Premier box build

[3stagevtec]

i bought me some new toys for Christmas.. time to break them in..

20mm MDF.. for $230 a sheet in Sando



all cut up and ready for assembly. the box i designed is 2.5cu.ft tuned 35 - 36Hz.. off axis port..



what madness is this! my 1st attempt at kerfing..



the right of the kerf is the port length, the left is the side of my enclosure



box 1/2 way assembled.. time to bend the kerf..



SUCCESS!! it didn't break...



every wall is braced and i'll be using a double layer baffle..



resin is about 2 months old! it get kinda lumpy but still works.. fiberglass reinforced of course..



now it's just to wait for the resin to dry to test em out...

[3stagevtec]

oh, and the Pioneer...





vids and a small review will come when the resin fully cures..

i went traders club and saw the level for ~$170, it have a laser light too .. say i had to get one yes..

i bought the table saw and some 36" clamps as well.. was really waiting until i had the correct tools to build it..

the box was supposed to be 2.6cu.ft tuned 35Hz, but that was calculated using 18mm MDF.. right now, by guess, i'd say it's around 2.5cu.ft tuned 36Hz.. (i forgot to factor in the resin volume into my calculations)

da table go mash up horse

[markzz]

nice work bro looks great

[fuzz_174]

nice

[raynice]

DIY likeyourself...

[Chiney]

thats wah we talkin bout right there!!!!

[3stagevtec]

i think i messed up the tuning.. the thing playing too low! (i.e. not loud enough). when i checked back, the tuning could be as low as 32Hz..

i messed up the port length measurement, because of the kerf i guess..

the sad part is i aleady glued up the entire box.. will have to work a magic to adjust that port... those who coming today should get to hear it..

[jeff]

ways i missin out yes, i would have liked to hear this play music...

btw poor table

[riadb]

heard it today....it really playing alot of lows and the port could have a tad bit more surface area but it sounds great for a daily play box IMHO.

you can cut the box keeping the same port length and this should increase the tuning frequency or you could stuff the box with bracing....it's gonna get madd heavy but it should help the situation.

well i find it sounds good\low for daily use ...

[Loudsound Customs]

nice build dey man......well done.....

[3stagevtec]

nice build dey man......well done.....

thanks man, now i know what it's like when you have to bend those big kerf's... pressure!


for daily, it sounds great! but i still would like to get a lil more impact from it.. (i got accustomed to my Audiopipes sound i guess)

funny story, would you believe the Hollywood Excursion sub sounded completely different in it, hitting hard / low! imagine that..

[3stagevtec]

with the sub installed..

[threeplumes]

i wish i had one under my christmas tree

[fuzz_174]

[DJ Q]

[pyromaniax]

[yos19]

[3stagevtec]

you'll get to hear it when you finish the march...

[snouter]

hmm interesting, ah wonder how a re will sound in this box? low like crazy

[3stagevtec]

3 layers of fiberglass / resin on the inside







resin 45 degrees on the braces for additional rigidity..



the entire surface of the box was covered with reisin.. extra resin was poured over all screws..



one orbital sander and a few hours later..





smooth as glass!



i didn't finish sanding when i took the pics.. you can see the unsanded resin on the right of the pic..






the reason for the resin / sanding is that i'm planning to paint and clear coat the box.. the final product should look at sound awesome..
