These pair of subs were used in a previous project.
They handle 400 watts rms with 1000 watt peak.
The subwoofers are 8 ohm resistance EACH. Together in parallel = 4 ohm.
Great condition, just silicon residue from enclosure bonding.
Excellent for low powered car audio systems if you are looking to get heavier bass results from a single battery system. No need for high current amplifiers unless you run these speakers in combination with lower impedance subs to make your setup pound.
Excellent for the Home Audio enthusiast as well if you want to shake your home studio, theatre or neighbors.
Although for both applications, knowledge of enclosure fabrication is complimentary for best results.
