Those are ugly amateur speaker cabinets and have a negative value, plus the fact you can't put different bass speakers in the same box. So this was a hack amateur job from the outset.
Your next problem is that you do not have the Altec Crossovers for the Altec 604Es, so this detracts from their value.
If the crossover was designed by the same person who designed the box, there will be not much to be said for it.
The Utah driver is a mid price driver, of much lower quality and value than the Altec. From what little I can find out about them it seems they were very crude crossovers.
So I would value each Altec speaker at $450 to $650 a piece. That seems the going rate. The correct crossovers seem to fetch from $200 to $500 each depending on condition.
I would think your crossovers are pretty much worthless.
The Utah speakers I will value at $75 each.
No one in their right mind will pay to ship those cabinets. The only thing of any real value you have are those Altec 604 E coaxial drivers.
