One of the first of the Dayton line this 12 is an exceptional value in performance and warranty. Though it is an odd beast with a dual 8 ohm coil, it still can mate to an bridged 2 channel or in pairs on a stout mono amp easily. The power rating is a bit misunderstood as most have tried to feed it the max power in larger than Qtc 1.1 enclosures and caused failure. The 600rms rating should only be put to it in the smallest of boxes which may not fair in smoothness. It's efficiency can make good use of 300-500rms watt amps (per sub)in the normally used box of 1.2 cubic feet. The general consensus on the proper sized sealed with it is actually 1-1.2 cubic feet as many have found out and by going larger only lessens it's actual performance in autos. Depending on the actual cabin gain of the particular vehicle and individual musical tastes it may be possible to go a tad under the usual size. The sub has a fairly low F3hz in most sealed boxes so you can see how predicting the proper box size in a car with it could be quite erroneous. With that a steep order x-over, box stuffing,and possible eq-ing could be needed to tame it a bit. Still don't discredit it, for it's capability in moving air in the lower register is outstanding in it's price range compared to most auto subs. It's upper bass is decently smooth enough to blend with a small mid bass/midrange up front to not need a stout separate mid bass pair. I've actually had it mated to a amped pair of Audax 4 crossed over around 150hz(12db) mids in the dash and it was astonishing how they blended. This was in a small SUV (S10 Blazer).It's too bad they have discontinued it. I would rather they have revamped it with a rubber surround and/or more durable gasket. The foam surround is sturdy but as time goes on it may deteriorate in very harsh environments. The front gasket is awfully thick for it's cheapness and often times will come apart even straight out of the box. Doesn't hinder it's performance, just aesthetics. Now anyone reading this may wonder why in the world am I reviewing a discontinued driver. because I still have a brand new one (replaced under warranty) still in the closet. LOL!!! Yes they are worth holding onto for those special projects and deserve the credit they never really had! The sub is simply a budget beast with a quality build.Had to add that this sub has recently become available again. Not sure why, but that's a good thing!

First my single negative: If you mount this driver with screws through the holes, the narrow rim puts the mounting screws too close for comfort to the edge of the mounting cutout, especially if your enclosure is built of soft material like MDF. I used 3/4" plywood over 3/4" MDF for the mounting baffle and put the screws outside the rim with flat washers to hold the driver against the baffle.That done, this driver in a 1.75 ft^3 sealed enclosure, measured with Dayton's WT3 Woofer Tester, yielded system resonance at 35 Hz with Q(ts) of .85, making for an easy stretch down to 20 Hz with a Linkwitz transform boost. Not a bad result for a first-time subwoofer builder like me.
