There are many of you who have the IP112 or IP310 and wouldn't part with them if your lives depended on it - and with good reason. They represent the cutting edge of bass technology, and they sound AMAZING. In fact, I didn't think there was anything that would blow me away after experiencing them... That was, until I played through this. http://www.bassemporium.com/item.php?sku=IP3103 I spent a while with this beast on Saturday. It's the only one in existence, and it's absolutely DEVASTATING. I've never heard one cabinet produce so much volume. Ever. It has a 1000 watt amp for the woofers, and a 500 watt amp for the mids and highs. With the gain at 9 o'clock on the pre, and volume halfway on the IP.. It was too loud to stand in front of. It literally made my pants flap. On top of that, it sounds absolutely BRILLIANT at any volume! I couldn't make it sound strained, even at the level to where it was making my keys rattle, which were sitting snugly in my pocket. Remember how revolutionary the IP was (compared to everything else) when it came out? It's that, all over again with this one. It's really too bad Jim doesn't plan to make any more of these, because I want..... Three of them.
