Can you open up the box ? Take the 4 screws out and flip it over and snap a picture of the internals. Do you know what components it was used with ? I'm thinking maybe an N500-D something or other.I think I have seen these before.I'm not 100% on this.I'll try to dig up the picture I have seen before.

It has a strap for 2 HF units and for dual woofers.As far as I know Altec only produced these old style XO's for a 500 Hz cutoff Frequency.These are old VOTT Crossovers.

This old style crossover faceplate is quite old..

I swear I just saw a pair of those on Ebay the other day.

IPC version of N500, not sure what the IPC model number is. Also i think it's a parallel network whereas the Altec version is a series network.

cradeldorf, I "borrowed" that picture from ebay. I was to lazy to get my camera out.

bowtie427ss, who is/was IPC?

Thanks, Tre'

Thank you. So these were not made by Altec at all?

[Altec Best]

Yes they were.They were rebranded (IPC) but they are essentially Altec Crossovers.Same for their 515's and 288's that are quite common.
