QED Reference Subwoofer 40 benefits from over 40 years of award winning expertise. All QED cables are designed using the top down principle with the Reference range representing the pinnacle of musical performance. QED Subwoofer 40 was designed primarily for low capacitance as this has been identified by QED as one factor which leads to a hi-fidelity experience and makes for a tight sound which retains the rhythm of the original piece.

This is vital when it comes to the 'bottom end' minute timing errors are eliminated by the use of QED's complementary conductor technology and a special floating Zn/Mn ferrite jacket. These technologies absorb very high frequency noise signals outside the audible band. The QED Analoc plug design eliminates eddy currents which affect the micro-timing of the audio signal, maintaining the fidelity of the audio signal from start to finish. Reference Subwoofer 40 is further optimised by having a 25% smaller diameter than Reference Audio 40 making it more convenient for those long runs around the room.

Conductor Technology

Conductor Technology

Complimentary conductor technology improves timing and detail, retaining the rhythm of the original piece. Unlike conventional analogue interconnects, Reference Audio 40 uses two silver plated 99.999% oxygen free copper conductors of different diameters to carry the same audio signal. This has the effect of providing an alternative signal path for more subtle audio components which might otherwise become time smeared in a single audio pathway.

Internal Ferrite Jacket

Internal Ferrite Jacket

The floating internal ferrite jacket absorbs high frequency noise signal components outside the audio band. When measured using high frequency measurement equipment, Audio 40 products convey a comparably cleaner and tighter signal pattern when its special Zn/Mn ferrite jacket is present. This has a beneficial effect on audio signal micro-timing and may account for the clear preference expressed for the ferrite jacket in listening tests.

Analoc RCA Plugs

Analoc RCA Plugs

This all new locking design features small high purity gold plated copper conductors in place of the usual large volume brass body found in ordinary high quality plugs. This cuts down or eliminates the tendency for the changing magnetic field in the conductor to induce eddy currents which are thought to affect the micro-timing of the audio signal. Coupled with its hollow central pin, the new QED Analoc plug maintains the fidelity of the audio signal from start to finish.
