Human Speakers Pro 005 8" woofer?

[DaveFred]

I have been thinking of building a sealed 2 way or 3 way with an 8" woofer.

Of all the woofers that I have looked at, this one seems like a steal,

HUMAN Speakers: PRO 005 Woofer

with an F3 of ~40Hz in 30-40 litres.

Has anyone used this woofer?

Or seen a frequency response graph?

Info on it is very hard to find.

Any other suitable 8" woofer candidates for a sealed speaker that goes down into the 40's and doesn't require a huge volume?

Thank you,

David.

More information about the usage would be great. I can get a 8" sealed woofer to 20hz with decent sound pressure in a car cabin, but it would be wholly ineffective in a great room in a home.



Extension, box size and efficiency, pick any two. While there are car audio oriented woofers that extend low, and have decent excursion they will have too much inductance, and will not reach high enough to mate with your tweeter.
