I have 2 fostex FE208 sigmas sitting in boxes and they will rot to hell eventually since I will never use them. I do however need a 2x8" guitar cabinet...so...is there any chance I can build something to hold these babies and use them for a low powered tube amp with my guitar? (5 watts). forget about me selling them or trading them, I live in central america (some of you know me) and thta is virtually impossible SO...karlson? bass reflex? sealed enclosure? they will used for bed room duty so I dont need to go too loud...any ideas? Dennis (DJK)? anyone? dumb idea I know but instead of them sitting on my shelf for eternity I thought about using them...as I pondered it seemed like there might be some possiblity...thanks, T

I used a pair of brand NEW sealed automobile subwoofer enclosures (hold the carpet please) to house a pair of 6 1/2" Phillips AD7062 full range drivers.
I painted the MDF cabinets black & white, added extra wood bracing inside and semi-filled it with fiberglass insulation, and I was....good-to-go!!

I am worried a little becuase of the wierd parameters of the fe208sigma. QTS of .21, xmax of .75mm. seems like it would be VERY enclosure sensitive. it might be easier because we are just talking covering the guitar frequency range but I wanted a few people to chime in. I thought about a 2x8 bass enclosure like for a car, would be so easy to build! thanks for chiming in! T

a VAS of 36.9L ??? scares me to think I can just drop it in a small sealed or ported enclosure...what am I missing?

They model pretty well in 7 liters each tuned to 80Hz.
7 liter? isnt that like 10x10x4.5" ? the speakers wouldnt even fit in that! they are 5 inches deep and 9 inches around...can I use a bigger cab with a different port? thanks, T

thanks bill, so we are talking bass reflex or sealed enclosure at 7L? if not sealed what port size would I need? Could they share a baffle at 14L like a 2x8" box or do I need each running in 7L? thanks again bill for the feedback! warm regards form sunny el salvador, T

A common 14 L box is fine. For your application, either sealed or vented would work OK. For vented try a 3 in. diameter X 3 3/4 in long port (7.6cm dia. x 9.5cm long)
looks like I can build a 24 x 12 x 10 enclosure with 3/4"plywood, divide in the middle and get the right volume...T

I wouldn't do sealed, with the very low Qts response will be thin below 150Hz, and a 5w amp won't allow you to fatten the lows with EQ.
thanks Bill,
I have some 28 or 30L boxes around, what kind of port should I run on those?
or should I just go ahead and build some smaller cabs? what liter size should I go for with what port?
thanks for all the help!

Thanks, sound right, when I looked at Qts (.21 and an EBP of 195 I though vented made sense. I will proceed as you suggest. thanks! T
