Two-Rock Speaker Cable

Coupling your speaker cabinet to your amplifier always requires a quality speaker cable. We now make our own Two-Rock speaker cables by hand using high quality materials. These 3 foot cables will deliver the reliability and tone your amplifier and speaker cabinet deserve. 

In addition, we now have both in-phase and out-of-phase options, referred to as standard or reverse polarity respectively. If you're not sure what to get, here's a brief explanation from Eli, CEO of Two-Rock Amplifiers: 

"Most reverb amps are wired out-of-phase. We just brought attention to it by wiring our Two-Rock cabs out-of-phase as well to match our reverb heads so you could use a standard speaker cable to match the phase of the amp and cab.
 When the amp and cab are mismatched there is a very subtle difference and it WILL NOT DAMAGE your head or cabinet if you run an amp head wired out-of-phase with a speaker cabinet that is wired in-phase.



Take any Fender amp with reverb in it (Deluxe Reverb, Super Reverb, Twin Reverb, Bandmaster Reverb etc.) for example, if you plug into the NORMAL channel the amp is in phase, if you plug into the VIBRATO (reverb) channel, it is out of phase. So to hear the difference turn the reverb off and switch between the Normal and Vibrato channel and listen to the difference. You would typically never change the speaker wiring on a combo amp. Engaging the FET on our amps also flips the phase of the amp, or for that matter going to the middle pickup on your Strat will do the same thing.
 

I geeked out on this for years and now I rarely even think about it. The main difference that we’ve been able to hear is slightly less low end if you run a mismatched head and cabinet. But like I said this is not a “Two-Rock” issue, this goes for any amp that has analog spring reverb in it. When playing live I use the same couple of speaker cabs regardless of what amps/phase as it is such a subtle difference that sometimes I prefer one over the other.
