WHERE TO BUY: Transmission Audio (Sweden)
At $2 million, Transmission Audio’s Ultimate system is truly the pinnacle of bank-breaking speaker systems. I’d wager it sounds pretty good as well.
Ultimate consists of twelve 500W speakers, an Audio Laboratory BP-1 dual-mono power amp and a BC-1 preamp. In addition to the already impressive array of speakers, Ultimate also features forty 15” subwoofers and another twenty-four 8” woofers. On the high-midrange and high frequency levels, ribbon technology is employed for high fidelity and reliability.
