from Walmart Year / Model Reviewed: 2001 Jensen XS1212 Strengths: Exceptionally efficient and suitable for hornloading and quarterwave enclosures, Qts-Qms work of audio art.The enclosure determines the results.Suitable for high-compliance Watt-for-Watt SPL competition (130dB+).Highly recomended.Low cost. Weaknesses: The drivers suspension may bottom if power greater than 55W high current(160W low current)is applied below Fo.This driver was never intended for power in this range in a ported enclosure and care must be taken. Summary: I'm an acoustic engineer and in my years of experience I have tested, built, and sold many drivers.I bought two Jensen XS1212 drivers and it took 52 hours to break them in with a modulated sine pulsing form 20 to 75 hz at 40W.These drivers are exceptionally efficient and possess the inherent properties(Qms and Qts) required to be used in quarterwave and foldedhorn enclosures.When properly loaded into a resonating enclosure a single driver can exceed (vehicle cabin)130 dB(50-55Hz) with 30W high current and maintain a F3 of 30Hz and an Fo of 26hz.Using stock deck,no amplifier, literally my voice will flutter with the pulsing sound waves and the vehicle as a whole resonates violently.After 5 minutes my ears were in pain for 6 days.A superior driver.Powerful amplifiers mean nothing-acoustics mean everything.JF Similar Products Used: MTX Thunder7500,Clarion SRW 1243,Rockford Fosgate P115s4,T212D4,P315D4,Pioneer TS-W3002SPL,ETC.
