Cable Length Query

Al, if running 15ft magnet wire on Mirage speakers with Minimum impedance: 4.25Ω at 93Hz
Estimated nominal impedance: 6Ω

Is the performance of the speakers compromised by the length of the wire?

Thanks, Elizabeth. Emerson (Foster_9), can you describe the speaker cables more specifically, including what gauge they are? And are they a specific make and model, or just generic two-conductor hookup wire?

Al, JW Audio Cryo Nova. I think it is 12awg solid core OFC.

Emerson, yes the JW Audio Cryo Nova is described as AWG 12, consisting of two solid core conductors twisted together. A 15 foot length of that cable is reasonable in terms of resistance and inductance, relative to the impedance characteristics of your speakers. And I would feel safe in assuming that the capacitance of the cable would be no problem for any reasonably designed amplifier.

Given that, IMO all that can be said with certainty is that whatever sonic effects the cables may have will be greater than if the length were shorter, essentially in proportion to the length difference. Beyond that it comes down to speculation. My speculation is that compared to say a 6 foot length of the same cable, the differences are not likely to be great enough to warrant concern.

Wow, thanks everyone for the information. I have a SIM Audio Preamp and just purchased a Krell KSA250. Like Elizabeth, I have built into the left wall a custom equipment enclosure. However, the Krell is too deep to fit into this rack. Coupled with the weight, I plan to set it between my Martin Logan Ethos speakers. From the back of the rack to the center of the wall would require a set of 4 or 5 meter XLRs. This is the first time I have had the opportunity to have balanced cables.
