    american bass xd-1800, three VFL-1222 subs

    5 channel recommendation.

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

    American bass VFL-8" woofer depth?

    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 considered "mid" school)

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

    American bass VFL-8" woofer depth?

    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 shit 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" thick mounting ring on her box and put a 10" sub in the same enclosure and she's happy now, i'm sure its way undersized for her diamond audio CM3 10" subwoofer but she's happy with how it sounds now and thats all i care about.

    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 pretty proud at how good of a circle i cut out using a really old craftsman jigsaw.

    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 thats 14" x 8" x 1.375" (had to get the box over the center up in the floor for the driveshaft/transmission) once i have the box carpeted and everything installed i'll probably post a picture up on the forums.

    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 playing some music and it cut the output down so much that it was pretty pathetic. Granted the box is completely too large for a sealed enclosure. I Cant wait till i get my amps setup and everything mounted and carpeted in the truck. I really appreciate the help, i would have never been able to get the sound output right without you guys. from what i'm seeing it should be tuned to "around" 34HZ matthew

    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, i'm pretty sure i can, but i mostly accounted for 4.125" and was planning on screwing some screws through the pipe then cutting off the access of the screws. so the pipe will be rigid inside the box. Either way it's gonna wait till tomorrow, its damn cold outside now.

    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 to 37HZ i can add a few more inches to the port and the box will be approx. 0.76 CF of air space which i think would be optimum from what i'm reading, almost every sub box i've viewed on Youtube that runs the american bass VFL subs is between 0.75 and 0.80 CF per sub. and they are ported.

    *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 dont want to use the orion amps, I'd much rather have a single 5 channel amp to run everything. I've got a memphis "big bell" 5 channel amp in my audi wagon and it does a great job. The HCCA 225's that i have could run my 4 doors and the 275 on the sub, but it seems extreme. I've also got an american bass XD 1800 (early 2000's i think) and an american bass SQ900 (not sure what it's 2 ohm mono rating is) i've got quite a few other amps but i dont think any of them are up to the task. but lets just use the orion as the example for now. The box i'm building is approx. 28 inches in length (26.5 internally) its custom for the pickup truck so rebuilding it isnt really the best option, i could shorten the box some but then i wouldnt have the best length for a round port and i'd have to go with a slot. *IF* i go with a round port it will be ported out the side of the box under the passenger rear seat (i dont see this being an issue as it will have about 20" or so of room between the port and the passenger rear door) from what i'm reading i need about 4" of room between the port and the inside wall of the box so that i'lll have plenty of room for air movement. so given that recommendation from box desing, i can be no longer than 23.25 inches on my port length. although it does seem that the larger the box, the shorter my port length is. I guess i need to finish building the box and get the 100% accurate measurement of the airspace inside of it then remove what space the port will be taking up.

    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 accounting for basket size and what the port itself removes from the box.

    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

    American bass VFL-8" woofer depth?

    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 airspace after the basket size, and my passenger side has a tang-band Neo 8" sub with .4 CF of space. the Tang band is driven by an orion cobalt 500.1, and the VFL 12 is being driven by a memphis "big bell" sub channel. my pickup truck is still yet undetermined on the amps i'm going to use, i have a dozen or so different ones i can choose from, but i'm considering using an HCCA275r for the sub at 2 OHM, and two HCCA 225's for the front/rear door speakers. Those amps put out amazing SQ.

    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 thing is i have a pair of Tang-Band 8x12 woofers (they are no longer made) that sound great but i really dont want to put an oval sub in my truck because they look strange and i have no grill for it.
