$US1 million gets you: a complete original Transformers boxed collection, a speedy car or...one. single. speaker. At a mil per channel, these speakers are almost as big as Transformers, but I'd still rather have Soundwave in my living room.
Made by Transmission Audio, this handmade speaker system has 12 separate, open-baffle dipole panels, each nearly seven feet high. Those panels are arranged to create a 37 foot wide speaker wall, and combined they weigh just a little over four tons. So, all you really need to enjoy the best sound possible is deep pockets, high ceilings, and one very reinforced floor. [Ultimate AV Mag via CNET]
