Hi
I'm looking to replace the following drivers. Greatly appreciate your help in sourcing these. Came out of a diy that I picked up over the holidays. Would be great to find a relatively "close" replacement.
Thank you very much in advance.
vifa "M26WR-07 04
10.7" woofer.
I've searched and all I can find is the M26WR09 series. I'm pretty sure the 04 represents 4 ohm as the driver is marked that way.
Scanspeak PL18W006-08
7.1" midrange/woofer
According to Parts Express, here are the specs

OK, $64 question. What is the enclosure size, and is it vented, and if so what are the vent dims?

Howdy,
You'll also need to say whether those dimensions are outside or inside of the enclosure, and if outside, the thickness of the material they're made from as the internal volume needs to be determined.
Plus, the length and diameter of the port is required to work out the port tuning frequency (assuming it's round).

That's the outside dimension.
Wall widths vary.
Each driver has its own compartment.
Bass woofer compartment is 61 liters.
Will try to measure port.

What is wrong with the drivers? Both the M26WR and the (Vifa?) PL18 were excellent in their days. Replace them and you'll need to correct the crossover. If the original was any good, that is. But here you have some (known) info on the production codes.
