Introduced in 1994, Alpha-Core's GOERTZ™ loudspeaker cables have won international acclaim for virtually eliminating distortion even in the longest runs. GOERTZ cables are flat and may be placed under carpets or behind baseboards if desired. Since the flat architecture is not always required we are now introducing a selection of sturdy cables based on the patented GOERTZ technology but with important added features. The new flat conductor cables are round in cross section and named the Serpents due to their shape and shimmering, speckled pattern. Please note that the Serpents are here to supplement, not replace the GOERTZ cables
.
Python MI2, the first Serpent, is electrically and sonically equivalent with our most popular GOERTZ MI2. It contains four film insulated flat, solid OFC copper conductors sandwiched intimately on top of one another and then twisted and embedded in a cylindrical, solid jacket of high grade polymer. The resin is cast in place to totally support and protect the flat conductor bundle, meaning that Python can take any amount of punishment and still sound and look like new.
The newcomers are true low inductance cables just like our original GOERTZ brand, but the twist enhances noise rejection even further to effectively prevent RF and EM interference from entering the feed-back loop. Python MI2 may be terminated either for 10 gauge single wiring or 13 gauge bi-wiring. When ordered for bi-wiring we recommend Rhodium Banana plugs rather than spades at the speaker end because the flat conductors with spades may prove awkward in case of a tight binding post pattern.
The second Serpent to hit the market, the Boa MI3 will co-exist with our big boy GOERTZ MI3. Boa MI3 may be configured for either 7 gauge single wiring or 10 gauge bi-wiring.
Just like the GOERTZ cables, besides the OFC copper the Serpents are available in solid fine silver designated Python AG and Boa AG. To this selection we have added Python and Boa hybrids featuring two outside solid fine silver conductors and two inside, similarly dimensioned, copper conductors. The jury is still out on the Hybrids but initial auditioning indicates that paralleled for single wiring they provide the silver sonics without glare and excessive brightness, while configured for bi-wiring with silver for the highs and mid-range and copper for the lows, they offer an excellent, cost effective alternative to all silver cables.
The Serpents are available factory terminated with solid silver spades or Rhodium plated spades, banana plugs, or pin connectors. They can also be supplied in bulk for self termination.

Figure 4 illustrates comparative measurements using a 12 kHz square wave transmitted via (I) a 25 foot Goertz cable, and (II) a 25 foot speaker cable of conventional bi-wire construction, both driving a 4 ohms loudspeaker. The characteristic impedance of the two cables are (I) 4 ohms and (II) 100 ohms. (A) is the signal at the amplifier, and (S) is the signal at the speaker.
Time Base = 10µS
Channel 1 V/DIV = 0.5 V
Channel 2 V/DIV = 0.5 V
It is evident that (I) is entirely distortion free, showing only the unavoidable power loss due to cable resistance. (II) in contrast indicates a clear leading edge spike at the amplifier, and significant distortion or roll off at the speaker terminals.
