I need the following specs on an Eclipse SW8102 DVC subwoofer.

5000w Peak PowerSPL (Efficiency, 1W/1M) - 89.1dBNominal Impedance - 2/4/8 OhmsQts (total speaker "Q") - 0.42Vas (Equivalent compliance) - 75.9LMounting Depth: 156mmMounting Hole Diameter: 280mm

Here are the specs for your speaker.

Dual 4 Ohms Nom. Impedance

Fs: 40Hz, Qms:5.0, Qes: 0.90, Qts: 0.75, SPL: 84(dB), Vas: 5.204(Cuft)

That should help you design a good box.

The eight terminals are actually 4 with double slide ons for each. Each side has a + (positive)
and a - (negative) with 2 connectors at each connection point.
It is a dual voice coil thus 2 sets of inputs.
If you have a 4 ohm amplifier then you are ready to go with a left to one side's terminal and a right amp output going to the other. If you have 2 speakers this can get wild because you can run them in parallel
or series and reduce the impedance to 2 ohms if your amp is 2 ohm stable. If not-dont do it!
You will burn the amp up. See #58 on the right sidebar of this site. It will teach you how to get the most
from your setup. Bookmark the site. It has every kind of knowledge you need for audio or electricity.
Look for the DVC (dual voice coil) info.
"The image below shows the DVC speaker wired to both channels of a stereo amplifier. Each channel of the amplifier drives a 4 ohm load. " This looks like what you have to do.

The 500W RMS total wattage is for both coils combined. If you want to get REALLY specific, all of the industry-specific specifications are as follows.

Make sure to use MDF for the enclosure and use 1 inch thickness and use braces as well. This is a beast of a sub woofer. So give it the proper power it needs and make sure that your box is very solid in construction. If installed correctly and given the right power, this sub woofer is bound to put a smile on your face and rattle your bones. I hit 142dB with only one of these subs and im sure if i gave it more power i could hit the 150dB range. DON'T FORGET TO GIVE IT THE POWER IT DESERVES. Have fun dreamsystems.

Hello brandin_1,

I'm assuming that you have the new 12" eclipse. Look at the sub cone. If it is blue in color, you have the Model SW4210 12" DVC SUBWOOFER, 4ohm, 250W RMS,750W MAX. If the cone is silver, it is the Model SW6210 12" DVC SUBWOOFER, 4ohm, 500W RMS, 1500W MAX.

If it is an older dvc Fujitsu Ten 12" eclipse, most likely it is the Model SW9122. If it is a REALLY old 12" eclipse, it is probably a model 88120.

Hope this helps.

I suggest to use separate amps to your sub, get a 2 channel amp for your sub and 4 channel amps for your speakers.

Here are my Top 5

• Lanzar -OPTI4000D

• MA Audio- HK-4000D

• JL Audio 1000/1V2

• OPti 22.2 Power Amp

• AudioBahn-A5100T

build a box with at 8"hole in it out of particle board, dont need to worry bout displacement
or check out this page for the formula, i aint doin the math
