B Grade items may have been used, have damaged packaging, missing accessories or a combination of these (Motherboards may be missing I/O shields).

The total 136 watts of output power creates deep, ground shaking bass from the 6 1/2 inch bass driver and clear treble and high notes from the 4 inch mid-range and ¾ inch tweeters.
The system utilises a professional audio processor from Texas Instruments, with sophsicated features including electronic crossover, speaker compensation and dynamic range control which are carried on in the audio DSP to make the ampilifier perfectly match the speaker system.
The front mounted bass reflex port with carefully calibrated cross-section helps to extend the low frequency effect and eliminates air turbulence at the same time.
A dedicated bass signal output is available on back panel to make it possible for connection to external subwoofer.
The MDF wooden housing keeps the speaker system thoroughly grounded for boisterous volumes whilst reducing acoustic resonance. With a wireless remote included, the R2730DB can easily switch between audio inputs and volume levels. The side-mounted adjustment panel allows users to tailor fit bass and treble preferences. The R2730DB is an iconic system, producing audio from low bass to high treble notes that is sure to impress even the extreme audiophile.
