I have a Like New DLS Iridium 15. may 30 or so hours play time on it. I is a SQL sub. I gets loud and sounds great doing it. This is a true highend subwoofer. That has a retail near 600 bux and I should them in my shop for 480 each. You get the sub and grille and I have the original box. I will let it go for 210 shipped.
Also don't let the specs fool you. Just look at the sub. I run 1200 watts RMS to them and they ask for more. Its just the way the Swedish rate things.
