Was searching for a bass cab speakers, but my amp have only 8Ohm out, so the choice was really small. These speakers sound great for bass and guitar as well, also look very well-made.
Not sure about 450 watt power, coil diameter doesn't match the number kinda. But my amp is 100 watt only so it's seem even a good point if actual power is lower because it would be pretty hard to crank them up. These are great and really loud speakers if you search for some low-resistant ones.
