The “SUB” is often overlooked in many hi-fi systems. To quote Rodney Dangerfield, it just “don’t get no respect”. Poorly treated or just not appreciated for what it is, the sub usually gets relegated to a corner because low frequencies are omnidirectional, and then is just forgotten about.
For many audiophiles, the result is a lack of bass definition and articulation, which translates into an indistinct rumble that eventually becomes tiresome.
There are two main causes for this phenomenon: the signal feeding the sub and the power supply feeding the sub amplifier.
It is an error to think that interconnect cables and power cables are not important because of the limited frequency response of the sub. On the contrary, a lot of musical information is contained in this frequency range. How else could we distinguish a stand-up bass or electric bass from a passing train or the rumble of a thunderstorm?
The interconnect cable that feeds the signal from your preamp to the sub has a vital role: it must not filter any frequencies or their harmonics and it must not reduce the speed of musical attacks.
The role of a good AC power cord is to allow the sub amplifier to deliver its full power instantaneously. The result is an effective and convincing articulation while avoiding speaker cone overhang, which tends to produce buzzing and rumble that has nothing to do with the original signal.
We have testimonies from many customers who have reconciled with their subwoofers simply by using the correct cables. Some were ready to change their current subs, yet they discovered that once fed with the proper diet, they achieved the maximum performance of their component at a lower cost than replacing the sub.
Each device should be allowed to operate at its full potential. You will be surprised at the “new performance” of what you already have … it’s a promise!
