Engadget: Altec Lansing popped by our offices earlier today to show off the successor to its oversized Mix iMT800 iPhone / iPod dock. There’s not a heck of a lot to talk about in terms of changes with the iM810 — the dock is now iPhone 4 certified, the gold trim has been changed to silver, and the amber LED has been swapped for blue. The company does get some bonus points for reenacting the one scene from Say Anything that anyone remembers with the winner of its in-office John Cusack look-alike contest, however. The new dock packs in a 5.25-inch subwoofer, a seven band graphic equalizer, and a slot for storing its little carabiner-equipped remote — the hulking accessory can also achieve relative portability with the help of eight D size batteries. It’s available now for $300, Peter Gabriel album not included. Press release after the break.
