Dec. 19, 2011 - PRLog -- Role Audio Has Introduced a Compact, Portable, All-in-One, Stereo Loudspeaker System for Streaming Devices, Computers, Smartphones, and Other Sources.

Dimensions: 42 X 4.5 X 5.25 (W X H X D) inches (107 by 13 by 12 cm)

Now you can get true full-range audiophile music with the Sampan Music Box without the complexity of multiple pieces, a subwoofer, and a tangle of wires. With a built in 50 watt per channel audiophile amplifier and frequency response of 35 Hz to 20,000 Hz, the Sampan Music Box is the ultimate compact two-channel stereo music system. The Sampan Music Box is a stereo music system that is small, simple, powerful, and amazing.

Role Audio, the US leader in manufacturing small audiophile loudspeakers, announces the release of The Sampan Music Box, a compact 50 watt per channel stereo music system, for home audio, desktop audio, and portable audio.

The Sampan Music Box is a compact all-in-one audiophile solution for consumers looking to access high-quality audio from their computers, smartphones, internet streaming devices, CD players, and other sources. Users can connect these sources to the Sampan Sound Box's 3.5 mm or RCA stereo inputs. The Sampan Music Box uses a built-in high-performance 50W per channel stereo power amplifier and folded transmission line design to deliver crystal-clear full-range audiophile sound without the need for a subwoofer and other components. The interface is simplicity itself: one wire in to connect the Sampan Music Box to a music source and one wire out to connect it to a power source.

We developed the Sampan Music Box because our research and experience identified four major issues with compact music systems: (1) Most compact music systems have inadequate bass response, (2) they use separate tweeter and woofer designs that are not time and phase coherent and therefore not optimal for near-field listening, (3) in the all-in-one systems, the transducers for the left and right channels are usually spaced too closely for accurate and natural stereophonic sound reproduction, and (4) getting good performance from compact music systems usually requires multiple components, including a subwoofer, and a tangle of interconnecting cables and wires -- too much complexity for consumers desiring a simple way to enjoy music.

Our experience developing our Sampan Sound Bar taught us we could build a small single piece,  full-range system, with imaging, sound-staging, and bass response comparable to some of the best small subwoofer satellite systems. We took the design of our best performing mini tower loudspeaker, the Sampan, known for its imaging, its huge soundstage, and its bass performance, and a modified 50 watt per channel T-Amplifier, known for its exceptional audiophile performance, and combined them in a single ultra compact music system.

The Sampan Music Box uses two full-range transducers, that are spaced 37 inches apart, in folded transmission lines to deliver sound that is time and phase coherent and bass response that can meet the THX requirement for subwoofers. The enclosure measures a compact  42 X 4.5 X 5.25 (W X H X D) inches (107 by 13 by 12 cm) and it is certified green and formaldehyde-free.

Using a single full range driver for each channel means the sound from each channel is integrated no matter where you sit, with all the frequencies of each channel arriving at your ear at the same time. The transmission line design allow effortless low bass reproduction. The Sampan Music Box is a point source, minimum phase, transient perfect, crossover-less design that represents the holy grail of loudspeaker designs. The imaging, soundstage, tonal quality and bass response are stunning.

The Sampan Music Box can be used in a wide range of situations including:
As an on-wall music system
As a desktop music system for computers
As a portable music system
As a rear channel speaker system for high-end home theater
As an on-the-go music system for picnics and other occasions
