What's a good enclosure for Panasonic Metal FA-3459 8"?

[freddi]

got Panasonic Metal FA-3459 8"

qts seems much higher than posted tech-spec from Panasonic and could be guessed as possibility as seller saying it works well in TQWT

assuming didn't botch T-S what's cool for good compromises with this type driver?

when watching it play without a box, I advanced volume slowly on a track with bass and cone didn't move much further - it mainly went into compression and more modulation rather than increase of peak movement

by "metal" - is its wizzer aluminum?

in a 3.2M BIB sim below, 1mm is reached at 0.65 watts ~52Hz

60 inches height is pretty far from my 7'10" ceiling - how are these type inverted?

Is this a new 8" FR?

[freddi]

appears to be new production - -I posted its real (for my samples) parameters over at fullrangedriver - Qts ~0.51 or so - maybe use OB with woofer- ?

Hello Friends

I purchased a pair of these speakers, and I intend to construct a enclosure to them.
Did you get further information about these speakers?
And about its sound, have you tested it?

Thanks for your help

Hi Eduardo - - - I meausured the parameters as above but have not thought of a good enclosure - - - by qes it would be suitable for MLTL/reflex but may play in certain blh to remove the baffle step - - the only blh I have is BK20/201 and I might test and listen.

it could go on open baffle with a woofer.

wonder what enclosures various buyers have liked (?)

this Panasonic isn't as extended on top as Nirvana 10 but its sweet- - here's an inroom plot on-axis vs a Sammi 8"

Hi Freddy,

Thank you for your reply.
I received these speakers a few days ago, and I liked it.
They are very well made.
I intend to use it as middle, and include a soft dome tweeter.

Thanks,
