These Parasource products are designed and built in Canada.
We feel they are so well built that we give a 2-year unlimited warranty.
The Amplifier
AttheheartofthepoweredenclosuresaretheallnewParasourceampliers.TheParasourceamps
havebeendesignedforincreasedoutputwhileminimizingsizeandweight.Furtherreductionsin
weighthavebeenachievedbydevelopinganefcientswitchingpowersupplytofeedtheamps.
Housedinacustomdie-castaluminumchassis,theParasourceampliersisdesignedtopassively
dissipateitsheat,eliminatingtheneedforanoisyfan.
The PS10P uses a 400 watt (800 watts peak) amplifier to drive the 10-inch long throw woofer
(2-inch voice coil) and a 400 watt (800 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
The PS12P uses a 950 watt (3500 watts peak) amplifier to drive the 12-inch long throw woofer
(3-inch voice coil) and a 450 watt (900 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
The PS15P uses a 950 watt (3500 watts peak) amplifier to drive the 15-inch long throw woofer
(3-inch voice coil) and a 450 watt (900 watts peak) amp on the 38 mm voicecoil (1-inch exit)
compression driver.
