LaVoce 2" ferrite driver looks interesting

[freddi]

for $5.99 - perhaps there's a cheap but decent woofer for a cheap and cheerful little "FAST" ?

LaVoce FSF020.50 2" Ferrite Full-Range Woofer 8 Ohm

 

[freddi]

looks like it might handle around 8 watts with a low crossover - maybe it should be run higher up

using 24uF/2mH with 0.2 ohm dcr inductor (like Erse steel core) , displacement would hit ~1mm at 16 watts input
and crossover roughly around 350Hz.

Dayton 2mH steel core inductors (o.29 ohm dcr) are $4.85 each

Looks very good.

Personally would use it "alone" for a very good PC desktop speaker or background music source, or similar duty, given the Bass limitation, *OR* as, say, a 4 unit vertically stacked column on top of an 8" or 10" woofer , *or* a floor to ceiling line array, maybe on its own (some Bass will appear with all that cone surface he he) or aided by some real woofer.

A nice discovery, thanks.

EDIT: and would definitely consider biamping, if anything to be able to add a steep >200Hz highpass much easier and more adjustable than any passive one.

Great sensitivity for an 8ohm driver. It's underhung so you won't want to exceed 1mm xmax otherwise you'll suffer fierce distortion. edit: the xmax is only 0.2mm if you go by the more typical (Hg-Hvc)/2 - it's not going to like excursion at all. It'll probably be happier crossed 500Hz-1K depending how loud you want it to go.

 

[freddi]

0.2mm would probably cut its max output to ~90dB (~2 watts) with a 500Hz 2nd order highpass and still exceed 0.2mm a bit

I was looking at this one as an option instead of a 3fe35 Faital. It looks a little smoother for longer, gets quite hot over 10k. It looks nice too, but it's $25 not $5.

LaVoce FAN030.71 3" Neodymium Full-Range Woofer 8 Ohm

edit: On 2nd glance, that 2" inch looks pretty good as well, smooth until the very top

 

[Lingwendil]

Might be good for a small bedroom cornu pair, augmented by a small subwoofer?

 

[freddi]

Faital's rather generous xmax spec for their 4fe32 would allow a 400 watt nominal input in "FAST" duty , , , ,

4 for a $24 mini per side mini line array without the cool yellow "LaVoce" written on it.
1 for $25 for a fast with "LaVoce" writing
Decisions, decisions...

400 watts!? I have two 15" PRV pro drivers shoved through my wall infinite baffle. Both being run on a 250 watt sub amp with the knob usually around half way.
