What can I do with 2 2ohms woofers?

Wiring in series doesn't require double the wattage

Compared to wiring in parallel, to achieve the same SPL, you do.

Also a sealed enclosure will bottom out the drivers long

As opposed to what other type of enclosure?

35 watts can be 35 x 1 or 10 x 3.5, both are 35 watts. A 1 ohm load will draw more current and require less voltage. A 4 ohm load would require higher voltage and draw less current.


The 1500 watt rating is is the max the voice coil can handle but the cone would bottom out long before you could use that much power in a sealed enclosure. A vented enclosure would increase the power handling and also increase output. Only downside is output drops off pretty fast below port frequency and you need to have a subsonic filter.

Paralleling drivers can increase the sensitivity by up to 6dB.

IIRC sealed enclosures have better power handling everywhere except for the region where the port response is at the maximum.

Having two sub-woofers close enough together can increase output by 6db.

Then you'd need two amps. If you parallel them, the power going through them doubles due to the halved impedance.

I don't think you're right about the levels at which they bottom out, but I'm too lazy to load up WinISD.

good god. my 10W3 does about 300 watts and i think it's too overpowering at times

I guess my old setup would be a bit much then. Four 15" Cerwin Vega DVC Strokers with four Clarion class D monoblock amps (under)rated at ~1000w each.
