I know this post is a year old, but i'm curious if Louisiana_CRX still has the old sony "big red" forsale. 

ah, I see, I'm not very familiar with Elemental Designs but after looking at their stuff it looks top notch! definitely a nice amp, specs look about right for what i need, No idea what the person is asking for it. But in all honesty, i'm hoping to find an old school sony XM-7557 (or is that...

something your selling? something tells me a DD amp is overkill for a single 8" sub though. 

might be why i've been sick for the last 4 days, I've breathed in a bit of MDF dust i figure. I built a sub box for my wife's car and this one for my truck, my wife's looks like **** because it was supposed to be .4CF sealed for one 8" sub and she said it wasnt loud enough so i made  a 2.25"...

right now i can remove 5 screws that are stablizing the port to the box, and take the sub out and the port can be hammered back out of place, i cut the hole so snug to the port that i had to use a flat piece of wood and a hammer to put it in the box so its a pretty tight fit. I was actually...

the front is 28.25" x 9.25" and its double thick 3/4" MDF the back is 6.5" x 28.14" 3/4" MDF the top is 14.5" x 28.25"  the bottom is 13.75" x 28.25"  (so it has a bit of a wedge shape because of the front/rear height difference)  there is also a notch cut out of the bottom on one side...

I went a bit off script here and made the port 15.5" long with a 3" schedule 40 PVC pipe, so the box is a bit oversized but i just tested the sub in my home theatre room and it sounds pretty bad ass for a single 8" sub, out of curiosity i had my son cover up and hold the port closed while i was...

thanks, i just realized i forgot to take in account that schedule 40 pipe is actually 4.5" in diameter due to the thickness of the pipe which also affects my cubic feet.  I'm going to have to measure to double check that i can fit a 4.5" pipe inside the box through the brace i made inside of it...

finished building the box other than cutting the hole for the round port, I estimated that a 4 inch port at 20 inches long is approx. 0.15 cubic foot of air space, the box itself is 1.05 CF, and the subwoofer takes up 0.10 CF, so if i port the box it will be 0.80 CF of space, *IF* i tune the box...

*IF* i can move my seat forward enough in the back of the truck i'm going to attempt to build an amp rack behind it to fit all 3 old school (mid 90's) orion HCCA amps, i'll use an HCCA 275R for the single 8" sub  according to the manual its 600W RMS at 2 ohm mono.   Although i'll be honest, i...

so is that your way of telling me that i should keep a 4 inch port?  I have a 4" port now but its only 8 inches long, so i'll either have to  extend it, or build a slot port of some sort.  After i put some internal bracing in my box to keep it stiffer it will probably be around the .75CF  after...

if i go with a 3 inch port it wants 12.5 inches long

I'm not gonna pay for bass box, but i put all the parameters that i knew into WINISD and it says ported box, with  0.86 CF and a 4 inch port  approx.24 inches long. or a 4x4 rectangle port at 32 inches long.   Pretty sure i'm gonna go with a round port at 30 inches long. and it says tuned to 39hz

I'm having difficulty using the calculators to attempt to figure out how much space and port length i would need for a ported box for a single VFL 8   I've been a novice when it comes to optimum box size for years.   My audi wagon has a 12" sub on the drivers side wheel well area with 1CF of...

https://www.diyaudioandvideo.com/Calculator/SealedVsPortedSpeakerBox/ this was the site i used, it does put it closer to the ported side, but says it will work on either.  i listen to all types of music but probably rap/hiphop the least, but i do enjoy some EDM which can hit low.   The funny...
