How do you describe the world’s most powerful iPod speaker? We could tell you all about the handmade high quality craftsmanship, the balanced sound or the tube amplifier, but the best way to measure its greatness is in numbers. Measuring over 3′ x 4′ the Wall of Sound contains 28 individual speakers, has a frequency response of 40 Hz-20,000 kHz and is powered by 125 watts. The WOS might be a real game changer since most companies aim to achieve the smallest iPod speakers. We look forward to bigger and better iPod sound systems (until hopefully one comes out in our price range).
