BLSamuel Posted May 17, 2012 Share Posted May 17, 2012 Can't find any specs. Car subwoofer I bought a few years back online auction for $3 (plus $17.06 shipping). Packing list does not give date. Have to check for email receipt....don't go back that far. Box says. 8" subwoofer (for car I think) optimized four use in 0.33 cubic foot sealed box Kevlar composite cone 46oz strontium magnet Made in USA Online I found that it was built from 1999 - 2003. And a link to page in German for the 10" models. Packikng list had 888-515-2900 for Nexus audio.... "...for live talk with exciting people call 1-900...". So I probalby eaither got close to 1999 overstock or 2003 or 2004? No idea. No email receipt just packing list with no date. Looks to be very well made. But no T/S parameters? Any idea where to find T/S parameters? The Auto Tuba requires a long throw 8" driver so if anything like bass out of 0.33 cu ft box it's have to be "long throw"? Seems like that's be a nice fun project. Fit in our 2007 Ford Focus. Alea has trouble hearing bass so likes bass heavy sound. Have a Pioneer DEH-3300UB head unit. Cheap. Specs pretty good. Cheap off shore labor. And at least 3 pair of car speakers in garage. I think 4" Advent ICT (tweeter in voice coil gap), 5x7? Polks. ?" Audiobahn - great specs, can angel the tweeter. Poor build quality. But sound ok for as cheap. The Ab are new the others used but in great shape. A 0.33 cu ft encloser should be easy to fit in the Focus, surprisingly large trunk for a small car. The Auto Tuba. I'm sure I can make it fit. Whether she'll want to give up that muich truck space. Plenty of room in the Dakota extended cab or build to fit between the seats in the Grand Caravan - maybe but it would have to be narrow as Colemam 16 cooler we use on road trips is a tight fit.

BLSamuel Posted May 17, 2012 Author Share Posted May 17, 2012 Doh! Forgot the intentional low res (and fuzzy [:$]) pics I took. Sent an email last night ot the Tuba guy.... and totally unrelated... .but in same photobucket folder, some Macassar Ebony (Kookieburra sent me at least one pic..... kind of like a dark Georgia O'Keefe painting. Sorry for off topic but I just love the veneer on this.) If I recall a few years back he could hardly give the pair away for $2K Quote Link to comment Share on other sites More sharing options...
BLSamuel Posted May 21, 2012 Author Share Posted May 21, 2012 I did find directions to measure T/S paramets but needs signal generator and oscilliscope. Signal generator can be from computer software but I'm not so sure about oscilliscope unless there is freeware for that? Thanks Quote Link to comment Share on other sites More sharing options...
BLSamuel Posted May 22, 2012 Author Share Posted May 22, 2012 Asked FB audio geek friends. Made In USA Eminence comes to mind so sent email to customer tech support.... if they made this driver they may have T/S parameters in archive. I did find web site that said biult 1999 - 2003.

BLSamuel Posted May 22, 2012 Author Share Posted May 22, 2012 I contacted Eminence customer support and they said it looked like an Eminence and said there should be a small gray sticker with part number under the black rubber ring aournd the magnet. No sticker but a couplle of numbers molded in. Maybe 1 is the speaker part number? In which case I should get official manufacturer data.

BLSamuel Posted May 22, 2012 Author Share Posted May 22, 2012 Nope. Part number for the magnet cover. Found the serial part number sticker in the alternate location, inside one of the arms near the terminals. Part number sticker but part of it could be serial number? 8291 4 OHM 67-98080361 Quote Link to comment Share on other sites More sharing options...

I have built an AutoTuba, and will vouch for it as an excellent sub which requires very little power to make a lot of sound. Here are the driver specs for that speaker taken directly from the AT instruction manual: Target specs for the driver are fs 30Hz, Qts .30, Vas 30L, xmax 8mm or more. Drivers with specs within plus/minus 20% will work. The recommended driver is the eight-inch MCM 55-2421 (mcmelectronics.com). Other suitable drivers include the Dayton (Parts-Express.com) DCS 205-4 and the Tang Band W8-740. You may also use a ten-inch driver with similar specs, so long as it is no more than 5.75 inches deep. One suitable ten is the Dayton DCS 255-4. I think this driver would work fine, but the XMAX is a little low at 6.4mm. The instructions call for 8 or more. You would still get a lot of sound!

Here is a little review I did of the AT I built: http://billfitzmaurice.info/forum/viewtopic.php?f=13&t=16134 Thanks for the info. I will email or conact Bill Fitz Maurice with T/S parameters as they do have at least one other design that can use an 8" driver. And it might be close enough to add a lot of bang to outddor speakers or car speakers in Focus though I still need an amplifier for either one a puny 5 clean watts horn loaded probably better than 40+ in the recommended 0.33 cu ft box on the box. Auto Tuba and other small Tuba can add punch to Heresies but as my first subwoofer project do something that can hide in car - if can fit? I think so but take up a lot of trunk space. Our youngest daughter who drives it most of the time says sub is pointless as she has 45% loss in one ear and has hearing instrument though it should compensate pretty well but most hearing loss in the bass. Her good ear is maybe borderline normal but may be repairable. She just had her second tympanoplasty on her bad ear just before Christmas. Have a new Pioneer head unit to put in the Focus and some Polk 5/7 db series that should fit exactly or very well in front or back. Mabye some round speakers that might work in the other location. Might work. She's happy with the sound, it's not bad for basic factory, but likes the hopefully better Pioneer SuperTuner IIID and can hookup iPod up to the new head unit. More power than factory. I think even has sub level control but not sure. Need to read the manual. Some Focus models come with sub. This one I'm sure not but may be place for one? Small enclosure will need hefty amp. But probably not at all expen$ive but I've not really researched. [:$] Budget is pretty much non-existant for the time being so enclosure with what I can scrounge. Probably no baltic birch for a couple of months. I have 4x4' of 1/2" MDF. 4x8" sheet or two of 3/4" OSB. And 4x8 3/4" pressure treated plywood.

mustang guy Posted May 23, 2012 Share Posted May 23, 2012 From the AutoTuba build instructions: The recommended material for construction is one-half inch (12mm) Baltic birch plywood. Make sure wood labeled as birch is in fact Baltic Birch, with a thick outer face and equal thickness plies, not cheap Asian ‘birch’, which has a thin veneer outer face. Big boxes like Lowes and HD do not carry Baltic Birch. Baltic Birch is usually found at smaller lumberyards that cater to kitchen cabinetmakers, and usually comes in 5x5 foot sheets. Worst case, order your birch on-line. Other plywood species are acceptable so long as there are at least 5 full plies. You may also use MDF, but it’s neither user friendly or as durable as plywood. The overall dimensions of the autotuba sub are 32" long X 14" high X 13" (and up to 38") wide. Quote Link to comment Share on other sites More sharing options...
BLSamuel Posted April 18, 2015 Author Share Posted April 18, 2015 Was going to revisit this and ask if somebody wanted to design a sub... but given Mustang guys information I may just try an auto tuba as the plans are very affordable. Will post in subwoofers to see if anybody wants to put together a quick design that I can build next week in 2 to 3 days. Thanks Mustang Guy!
