Tannoy Crossover Capacitor 1000V ?

I'm new to this, so please bear with me. I recently got my hands on a couple of 15" dual concentric drivers. The crossover schematic shows (for High Frequency) - 3 separate caps at 1.3 mf @ 1000V, and one at .9 mf @ 1000V. For the life of me, I can't find these values anywhere!

Q1: Does anyone know where I can find these?
Q2: Can I use a lesser Voltage than the 1000V as specified on the schematic instead of 1000V?

Please help!!

Which drivers are these?

Unless you're using them as PA speakers, you should be fine with only 250-630V.

I would assume they are either the 3833 or 3836, the last person that owned them removed all the stickers/markings. There is no gold ring around the speaker, I think they are bit older, before the cpa15's I would assume...

This is a Tannoy supplied schematic, correct? I still find it odd that they'd recommend such high voltages. I believe my HPD's maybe came with 150v.

Are all of those caps in parallel?

Do you have a specific budget? Some brands such as Sonic Cap or Duelund can make custom sizes.
