Same speakers, same amp, same guitar, same player, same configuration... vastly different tone. Why on Earth?
I don't have an answer to this question, but it mirrors my experience. A couple of weeks ago, me and a friend have done a similar test, we just didn't record it. We had several amp heads and three 4x12 cabs, all with V30s. With each head, we did an A/B/C test with the cabs, quickly switching back and forth between them. The difference in tone was so vast that you would swear that they must be different speakers. That all said, the were different in a way. One cab had the speakers barely broken in, one had well broken in Chinese V30s that were a couple of years old, and one had some 90s UK V30s. Two of those cabs were (supposedly) the exact same model!Same speakers, same amp, same guitar, same player, same configuration... vastly different tone. Why on Earth?
First off the Microphone is in a different place - and the darker cabinet is recorded with less gain. It can also be that one of the cabinets has more insulation inside too.Same speakers, same amp, same guitar, same player, same configuration... vastly different tone. Why on Earth?
I was thinking about the grill cloth as I have two Fryette cabs, same model, swapped speakers to same different brand and they sound a bit different.Everything matters, even the grill cloth. But my vote would be for 1kg of pixie dust in the vintage cab.
It's the same these days - and back in the late 1960s was the time engineers figured out that in all speaker cabinets - one of the speakers would sound better than the others. As to the wood of a cabinet - that can hold true to a small extent - a rigid Burch cabinet that is glued and screwed together properly will sound a bit different than a Plywood Cabinet - but no cabinets construction can cause the treble difference as demonstrated in the OPs video. And the Grill Cloth can only cause that kind treble differentiation if it's not speaker fabric and some kind of non porous covering.I'm kinda surprised that this surprises people. Back in the day when vintage Marshall cabs where ubiquitous and we got to play a bunch of them, everybody knew that no two sounded alike.
For 25 years I assumed my homebuilt cab (see avatar) was disaster, but one day I pulled the back off and whoa! Instant vintage cab. Not for sale.Tuning a speaker cab is a real thing.
Try it yourselves with porting, back coverage, insulating material, cabinet size and shape.
Thing is, most will sound ok and there is no one standard or optimal performance target for MI speakers.
I am listening on an iPhone.How many of y'all hear this as 'vastly different?'
