The drivers will be fairly high quality ones, probably better than what you find in Hsu and Outlaw subs and certainly better than what you will get with a PSA sub. For a better driver in a commercial sub, you would have to look at higher than $1k subs, and with the Dayton kit you get two such drivers. This means low distortion, high output, good linearity, good compression behavior, and high sound quality.
Drivers & quotes from audioholics reviews:
psa xv-15 driver:
The 15” driver used in this system is constructed on a 12 spoke cast aluminum frame and uses a heavy pressed paper fiber cone with an inverted dust cap. The surround is a large half roll of Rubatek foam which should allow generous excursions. The voice coil is a 2” diameter copper flat wind with an 8” poly cotton spider providing centering and returning force. The motor is comprised of a triple stack of y35 grade magnets of about 5” diameter and a vented pole piece to remove heat from the gap. This driver appears to be sturdy, heavily built for a subwoofer selling in this price class and capable of withstanding large excursions. Power Sound indicates that the driver is capable of 2” peak to peak stroke.
outlaw audio lfm-1 ex driver:
After pulling the driver out of the enclosure to examine it further it could be seen that it was a well built and substantial unit but of moderate cost. The 12” driver is built on a stamped steel frame and a good sized motor of roughly 6” in diameter with dual stacked ferrite magnets. The back plate is bumped and has a small pole vent with a screen to prevent debris from entering the gap. The cone appears to be pressed and coated paper attached to a 2” diameter voice coil and former. The suspension consists of what appears to be a 6” diameter single spider and a rubber half roll surround. Interestingly the motor also has a large bucking magnet attached to the back of it for magnetic shielding purposes. This is increasingly less of a concern since CRT televisions are becoming much less common. The driver is of a very humble pedigree and built of unassuming components but is not out of character for a subwoofer in this price range and appears to do the job well, which is what matters.
hsu vtf-3 mk3 driver:
For my money, the real star of this show is the VTF-3 Mk3’s driver. It’s a nominal 12” unit, with a half-roll surround, and sporting a massive vented motor assembly. Hsu Research has, from its inception, focused on 12” driver as its driver of choice and they have over the years refined their design approach to where their products perform out to the limits of what a12” driver can do. In the world of subwoofers it’s easy to overlook 12” drivers, seemingly overshadowed by their 15” and 18” brethren. Underestimate the VTF-3 Mk3 at your own risk – this is one potent sub! For the specification-inclined I’ve included a table with some of the driver’s T/S parameters.
The words from the VTF-3 review were from a reviewer named Mark. The PSA and Outlaw reviews were from Ricci (and of course have more information). I dunno why you're a hater. They're all good products. I would imagine the Outlaw LFM-1 EX driver and VTF-3 mk3 driver are actually the same driver, but I of course don't know for sure.
