Okay heres the deal...I bought these subs odd ebay a couple of months ago and have yet to have them installed. They came with a sealed box, but im not sure of the specs. However here are the specs for the subs...
12" Dual Voice Coil Subwoofer
700W RMS / 1400W Peak Power
Dual 4Ω Voice Coils
120 oz. Magnet Weight
20-500Hz Frequency Response
92.7dB Sensitivity
Mounting Depth 5-5/8"
Cutout Diameter 11-1/8"
Can you guys give me some ideas on what kinda am I could use to power these subs. ANd also if you think that a sealed box is the best way to go. As for the amp, I want something temporary for now. I am really pressed for cash, but I need something to make these things hit. I dont need anythng too serious right now, cuz im only planning on adding these to my stock bose setup.

Well, some bad news for those subs. Each one needs about 4.6 ft3 in a sealed box. Sealed or ported will work for these woofers, but a ported box would be huge (as if the sealed is not
). Each sub will need about 600-700 W. so for 2 woofers you would need an amp capable of about 1400W at either 1 ohm or 4 ohms. (if you would just use one woofer, then a 6-700W amp at 2 ohms will work).
My suggestion...put them back on ebay and then consider yourself lucky if they sell. Then go here... http://www.edesignaudio.com/combo and get combo #1. A 10" woofer only requires a 0.5 ft3 box and it comes with a 3-year warranty

Those are features, not specs. Specs are things like fs, vas, qms, qes, etc that are used to design a proper enclosure. SoundDomain has a good glossary. link Originally Posted by nycspudz03

Well, if you want to get technical....SPL (Sensitivity) and RMS power are both specs. The rest are features.Originally Posted by Robert_J

Neither are required to build a box. RMS power is not very useful either. It's just the amount of power the voice could can take before melting. The amount of power a sub can handle depends on a lot of things: Enclosure size, type (ported or sealed), tuning frequency (ported only), amp power and program material. For example, you can't take a car sub tuned to 35hz and play Lord of the Rings through it at a high volume. The 10hz sounds in the movie are way below tuning and the sub will bottom out the driver with as little as 20 watts (dependent on the driver).Originally Posted by Rider69

There will be a parameter called Re. That is the DC resistance of the speaker which should be close to 4. Most 4 ohm speakers measure around 3.2 ohms DC. Actual impedence of the speaker will vary by frequency. Also, whether the coils were in series, parallel or a single coil should be listed along with the rest of the parameters. Some parameters will change slightly depending on how you wire up the sub (series or parallel).Originally Posted by slickrick
isnt dual 4 a "spec" also?

i forgot about Re.

I bought these subs also but my amp is MA Audio 2 channel amp at 4 ohms and pushes 1130 watts. It is a huge rack mount style amp.
I would say sell them and get sometihing a little smaller

as for how they sound... They arent hooked up yet plus I am leaving for vacation in 4 days so they wont be hooked up until I get back. I will be sure to put up a thread in the general forum.
