Klipsch R-12SW Sound Quality

The subwoofer has an awesome sound quality due to the high-quality built-in amp that comes with it. The all-digital design that comes with it gives the subwoofer extra power to work effectively and make remarkably heavy bass sounds. Since the amp is built-in, the subwoofer doesn’t really need an external power source.

Klipsch R-12SW sound makes it unique and stands out among subwoofers in its same price range. Some other subwoofers in this price range produce distortions especially when the volume is a little bit high. R-12SW plays all frequencies with only a little or no distortion whatsoever which helps bring out a clear deep bass sound. 

The copper diaphragm in the subwoofer also partakes in producing a clear sound. The work of the copper spun is to limit coloration and distortion in the subwoofer compared to those that come in other flexible materials. The copper might tend to cause a break in the audio signal while at a higher frequency, thankfully, only clear low-frequency sounds are played on the subwoofer. 

The subwoofer can surprisingly help you detect sounds you’ve never heard before since it contains less warmth but crisp and bright sounds. Moreover, the all-digital amp that comes with R-12SW delivers 200W RMS and 400W dynamic power equally impressive, enough power to get the exact bass for any home studio setup. Whenever a low hum is experienced on this subwoofer, it is mainly due to multiple devices being plugged to separate outlets or perhaps, the use of low-end cables. This can be sorted by using quality cables with short lengths.
