I ordered 2 of these subs on a whim. I needed a pair quick for an upcoming gig where space would be limited for using my passive subs and amp rack. I have been wanting a powered pair of subs and had my eyes on the QSC KS118's, however, the price for a pair of those were doubled. With fingers crossed, I put these subs in my cart and checked out.They arrived 2 days later and I was impressed when unboxing them. They look sleek and stylish, yet well built. I set the subs crossover to handle frequencies below 100 Hz to allow my tops to work light duty. I played a bass-heavy song as a test and dialed the subs back to -20db. They kicked out the bass and were nowhere close to the limit mark. I went as far a -5db and had plenty of bass for most events. I think -10db on these subs will be my sweet spot.They are marketed to be 2400 watts with RMS at 600w, which is why I was skeptical. However, they punch hard. I haven't tried them in cardioid mode, nor have I taken them to a gig yet. If they hold up and keep playing without any issues, I think these subs will exceed my expectations I had for them. Only time will tell.If I had to be nit-picky and find a Con about these subs, it would be the wheel option. These subs come with the bolts installed where you can add optional caster wheels. I went to several hardware stores and Harbor Freight looking for wheels. The issue is with the wheel plates. None of the bolt holes (spacing), match the wheels that are available. So I have 2 choices at this point. Either buy 18" dollies to sat them on, or machine a metal plate aligned with the speaker holes and mount the wheels to the plate, then plate to the subs. That said, I am pleased with the purchase thus far.

"Decent subs"

They pump some deep bass especially for the $1000 price. Would be great for first time subwoofer buyers. Would recommend other options They are somewhat cheap built. One of mine has a slight rattle to it inside.
