a Baltic birch single kerfed flared enclosure for a FI Q 12" ..... 2.25cf3 tuned at 30hz

I have a buddy that ad the same problem.... the diodes in the regulator failed causing feed back in the alt the alternator made a sizzling / buzzing sound when the car was shut off we had it repaired and the tech who fixed it says it was getting too hot

$400 for a plastic elbow ...... LOL

my wife calls it brain damage.........

the birch has different acoustics than MDF .... I was picking up a hint of color in the bass that I wasn't use to not as acoustically dead so I rib braced the shit out of all the interior panels ... problem solved nicer to work with than MDF... just needs a little more TLC on the assembly

that's for 2 tweeters , 2 midbass and the 2 subs ... no crossblock a guy in town purchased set #001 and he does not even have a car to put them in yet

I had 2 sets of the JBL 660gti in my ground pounder , they were by far the best components I have ever owned so far and I would not hesitate to use them again but a buddy of mine is the main Focal rep for the BC interior ...... he just had to show of the #7 component kit to me I'm thinking on using the Utopia's , put the midbass in the doors and the tweets and mids up in the pillars ... only decision is going fully active or use the cross block if I use the cross block I can still bi amp and use time alignment ... less chance of popping those tweeters he wanted to sell me the new Focal Utopia Ultima component set serial #002 ( pic below )but I think my wife would divorce me and never let me see my kids again......she would probably have me commited and put away...... LOL

ya... yay me... LOL that's the last enclosure I build for this car , I'm going to put a fiberglass pod and sub in each corner and build a nice amp rack and add a couple more batteries once I get my components installed

up here wasting wood and the lows are as tight as a ........

this one is tuned at 30hz..... JBL's recommended tuning ( not mine ) 30hz is too peaky for my taste .... I had the subs in my old Icon enclosure for the last couple weeks... it works out to 28hz and it sounded really good so I put it back in this morning .... not much room for improvement in SQ so I'm going to leave it as is for now

ya so this is one of those WTF moments..... I must be getting old..... anything tuned higher than FLAT sounds like shit to me now

got the subs in.... I'm not shure if I'll like the tuning or not so I'm going to leave it bare wood and play with it for a few days it is slightly louder in the upper sub range than the 28hz box but , some detail and impact is gone

the shit is harder to work with though the Kerfs are SPRING loaded , if you are bending and let go watch out ... LOL

the test fit was a success........ it could not be any tighter I'm liking the Baltic Birch ... I can barely lift my old Icon enclosure made of MDF .... I can pick up this new one and throw it across the room ... should help level the Magnums ass end

once I'm done with this one I was informed it would make a good 2 man speed sled give it a coat of turtle wax for maximum slippage.......dual purpose..... LOL

I'll have to test fit it tomorrow before I continue and see how the port fits up to the hatchback lid this Baltic birch is hard stuff..... takes forever to sand compared to MDF

for now on all my enclosures will be built out of Baltic Birch better quality , nicer to work with and it weighs a lot less

a Baltic birch double flared kerfed port enclosure for a pair of JBL W12gti subs

$2000 and no cd transport....LOL

I lost ALOT of output compared to the old enclosure but they really tightened up this 31 band EQ on the 99 is like Audiophile porn...CRAZY flexability on the low slows

LOVE this new Pioneer P99RS , I can adjust the x-over point and slope as I'm driving now I have to add something to fill in the upper mid bass......time to go active on the top end..

I think I got it...LOL

can't post pics......
