Sound Blaster Roar SR20A White Paper – Evolution, Concept and Tech Overview
Components and Supporting Technologies
The Sound Blaster Roar SR20A comes with the following components and technologies
that allow the loudspeaker to punch well above its weight in the wireless speaker
category:
Far-field Dual Left-Right Channel Satellite Drivers
The Sound Blaster Roar SR20A delivers highly detailed highs. This is due to the
inclusion of dual 1.5" high frequency drivers that are made for 'Far-field' high-frequency
dispersion. These drivers feature a Kapton voice coil former with excellent dielectric
properties for improved thermal handling. 'Far-field' here refers to the driver's ability to
"throw" sound further than competing portable speaker systems (not on the context of a
full blown professional monitor).
Bass/Midbass Driver
The Long-throw 2.5" heavy duty midrange/bass driver – that features rubber surrounds
with ideal flex properties -- is used for midbass bass duties for the SR20A.
Bluetooth 3.0
The SR20A features Bluetooth 3.0 wireless technology. This has all to do with the new
way we live, work and play. Bluetooth wireless technology is aimed at allowing users to
make effortless and fast connections between various devices.
Bluetooth wireless technology's adaptive frequency hopping (AFH) capability was
designed to reduce interference between wireless technologies sharing the 2.4GHz
spectrum. AFH works within the spectrum to take advantage of the available frequency.
This is done by detecting other devices in the spectrum and avoiding the frequencies they
are using.
Range:
Operating range is typically 10 meters or 30 feet.
Data rates:
Up to 3Mbps.
Also Bluetooth's high adoption rate enables very wide compatibility.
