Tangband 5x7 Woofer?...what sorts of applications is this suitable for?

[form109]

i've seen that 5x7 Tangband Woofer at Parts-Express for a while now and im wondering what sorts of applications it would be suitable for....obviouslly the 5x7 formats would make these seem fit for Car audio apps (given the oblong shape of the TB oval woofers wont fit stock openings without mods)

the listed FR is 40-500 so it obviouslly can't be used for a Typical 2 Way Design...it seems to be leaning towards bass applications

but with a 3 mm xmax it doesnt seem like a canidate for a subwoofer (unless its for a small room at very moderate volumes)

any thoughts on this one guys?

Hey form109, it would seem that they are intended for low bass support with a wide range driver. This would allow for use of a fairly narrow cabinet. This tends to improve the SAF of a speaker.

Peace,

Hmmm...

If it overloads gracefully, 3mm Xmax can be reasonable, especially if there's more than one used. I know my subwoofer drivers have 3mm Xmax (they go overload nicely though, 8-10mm p/p before harmonics become apparent), but I'm never left wanting (then again, it's a small room).

As Dave said, having them narrow would help SAF. 2 per side backed with a subwoofer for the really low stuff would probably do quite well.

Cone material ,PP or PET Naftalate ,should point it to car environment ---or cat habitat

Checked Tangband's Website.....and apparently It Is a Subwoofer....looks intreasting

It's not a subwoofer. There isn't the surface area there to move sufficient air.

Still, using them for rear speakers in a car may be something they had in mind.

Why are there odd shaped speakers like this in te first place?

[form109]

Tangband has it Listed as a Subwoofer.........and keep in mind Tangband does make small subwoofers....an example would be their 5" Neodymium subwoofer...which has 3 Times as much X-Max...but you get the point.

if a 5 1/4" Woofer is considered a Subwoofer why shouldn't a 5x7" Woofer be considered a sub.

A 5x7" driver is commonly used in cars. Also, as someone mentioned earlier, a narrower driver gives a narrower baffle, so WAF would be higher.

Hi,

I think these drivers are very good for sub intended for music if placed within ~0.7m from a room(< ~50 m^3) corner.
