    This XL2 speaker is so good that right after I bought my first one, I purchased another. I also purchased the sub8.2 to go along with the XL2. Best speakers ever!! Don't hesitate! These speakers are not just another
    purchase but an actual investment. I truly believe I could resell my setup
    for more than what I bought it for!
