new to your site
very nice site

i am an inventor (real job is a plumber)
i built a nice digital jobsite boombox already (can email pics if requested))

Boombox is a larger style of the old 80's Breakdance Boomboxes
All Plexiglass construction w/ a handle
Has an Ipod for Signal, a 2 channel DJ amp (rack style - on top) w/ a bass blocking crossover (recessed into rear of box) powering 2 Bose Cubes (from a sorround sound set), & a 1 channel Bose Sub plate amp powering a 12" Pioneer Sub

very heavy/bulky, but nice as hell


I need info/suggestions about a 12" - 4 Ohm - Handling 350 W RMS woofer (rating of plate amp i will use on next build):
a good/loud/clear free air woofer or 1 that requires a small volume enclosure
to be used playing rock/pop type music at meduim to high volume

im trying to keep the size & weight down on my next boombox; after all it will contain 2 amps, 2 Bose Cubes, crossover, etc.

trying to make the jobsite boombox smaller/lighter/better etc.

any info is much, much appreciated

Woofer or sub-woofer? I am going to assume sub.

Lots of choices here. http://www.partsexpress.com/webpage.cfm?webpage_id=3&CAT_ID=49&ObjectGroup_ID=487

I would go with this one for it's great sound quality. http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-464

This one for more output http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-466

Or this one for just sheer power. http://www.partsexpress.com/pe/showdetl.cfm?&Partnumber=295-404

There are better drivers out there, but these represent a good bang for the buck.

I don't know how a 12" woofer would sound with Bose cubes. The Bose woofers are smaller, partially because the cubes have a very limited frequency range. A 12" woofer probably would leave a large "hole" in frequency response between what the woofer and Bose cubes could produce. The result would probably be a thin sounding system that's missing the all-important midrange.

You might want to look at smaller woofers and build ported boxes to the recommended specs for the woofers... or look at some kind of 2-way speakers with 6 1/2" or 8" woofers to replace the Bose cubes. Possibly 6" x 9" or other coaxial car speakers...
