Need guidance, first spkr plans.
Hey guys, I'm new here. May I say great site?
I designed this spherical 2.1 speaker set and I'd like some input on my choice of components and how to crossover.
Total component list.
4x Aurasound NS3-193-8A 3" Extended Range
F3 of 85Hz: 2 to 3 liters sealed and stuffed
2x Fostex FT17H Horn Super Tweeter
1x Peerless 835017 XXLS 12" Aluminum Cone 4 ohm
2.5 cubic foot box with a 3" diameter vent by 13" long for an F3 of 30Hz
As far as plans go, they will be hooked to a DC powered amp and dac, via toslink to my pc. I'm trying to find an automotive amp rated for 8ohm for the speakers and 4ohm sub. I want the sub to handle up to 100hz, mids from 100hz-5khz, tweeter 5k-25k.
OK guys, hack away
3rd rev, tweeter more inline with woofers

the supertweeter is way more efficent than the mids, not a good match;
for power handling and baffle step correction, I'd look at crossing your woofer over higher, how wide will your mids cabinet be? - this determines the baffle step freq.
Impedance varies with frequency, use impedance plots of your drivers and make crossover calculations using the actual impedance of the driver at the crossover frequency

its sure a hell lot of work
might make more sense with better drivers
80db sensitivity is very low
maybe skip the MTM design
one good mid and one tweeter might give you a better chance
especially with the spherical mid design
best to have the tweeter slightly "behind" the mid, which would come natural with the spherical design
sometimes we know very little, and sometimes we know too much

Checkout the info on small drivers on Zaphs site, and small tweeters.

Thanks for the replies fellas. Doing some rethinking. How do you think a pair of lines of those woofers would sound? I'm thinking 9 per side arranged in a vertical arc for equidistance from my ears. Comb filtering shouldnt be an issue with a fixed listening position.
I've been flip-flopping between a multi-way / line design for weeks..
