I said this a couple times but I got no supporting replies so I stopped saying it for fear it would piss people off.
My understanding (and I could be wrong) was that a "marty sub" was just a specific design from LTD02 that was a good blend of performance, size, and ease of construction. It was basically just a plan for a ported box. Then the plan got tweaked into mini marty, full size marty etc. But really it's just a bunch of ported boxes, with the plans LTD came up with labeled marty cube.
But I did noticed that people will say they want a "marty cube", then want to change dimensions to fit a space or whatever- You really just want a different ported box, it's easier to design than try to reverse engineer a martysub and twist or contort it. I think the "marty sub" was based on the principle of being 24" by 48" or something similar so it can make efficient use of 4x8 wood sheets, or smaller precut pieces available already 2x4 at your local big box hardware store. But certainly not all ported boxes are marty subs, but certainly all marty subs are ported boxes.
I guess it does't matter really what you call it. The popularity of the name is probably a testament to the excellent design John did. It certainly caught on, but truth be told I had made a similar ported box for a 15" back in my car audio days in the late 1990's (24"x24"x24") just because it was easy and made sense. 24" ported cube subwoofers make sense. They just do. LTD just use the same concept with good bracing. Good bracing is a bonus
It didn't seem like a big deal back in the 1990's car audio when drivers were smaller and limited in xmax, but with today's 18" monsters used to chase single digit bass in home theaters it's very important.
I agree though, we should start calling ported subs "ported subs" again. Unless you are specifically building the marty sub from the cut sheet and copying LTD02's design you really are just building a ported sub.
Ok... now I need to be stupid and ask - why the name "marty" ? Where did that come from? Was it for the user martycool007 originally or something ?
