Altec 612 copies

[didier]

Hi guys,

I can't claim this as a home build as I'm not building them at all, just assembling the bits, but a cabinet maker friend is building me some Altec 612 replica cabinets.  3/4" birch ply with a dressing birch veneer over the top.

They'll be loaded with Altec 604 duplex 15" coaxials when they're done.

There's a fair bit of work to be done in the meantime, crossovers built etc but thought i'd share some progress shots.

Thanks Duc!

Yes he's extremely good.  In the middle photo you can see the one on the right is dressed in its veneer, the left one is still in its raw state.  I've always admired the simplicity of the 612 Utility cabs, of course normally they are painted grey but i love the birch so much i think i'll just lacquer or oil them.

i see .

yes oil them should be ideal . i use a lot of Russian birch on my plinths and i found lot of sanding and  oil the ply is the best looking ply . or go two pac .

 

cheers

nice, they look well made.

 

what crossover are you planning on using? and drivers - 604E ?

[blinky]

Ooooh nice! The cabinets aren't huge then I'm guessing?

[didier]

Drivers will be 604D, basically the same as the 604C, crossovers built by Werner, the fellow who makes Jabo horns.

 

The cabinets are not high, no.  I suppose normally in studios they would have been desk or wall mounted.  I'll have to experiment!

[damohpi]

good choice on crossovers, was going to suggest them if not..

[didier]

The crossovers arrived.

Won't the iron-core (instead of air-core) inductors saturate?

I doubt it, the drivers in question are only rated to 35W, you would exceed that long before those cores saturate

No, they'll be fine.

spot on.

Lovely work...well done.

 

A couple of q's:

 

What's the internal volume of the cab?

 

What's the approx cost of the xovers?

 

What sort of 604...vintage or Great Plains?

 

I've built large cabs for the 604 and other Altec components...so I'm really keen to see how yours turns out.

 

All the best.

Hi, I'll answer in sequence

- Internal volume of each cab is approximately 195 litres

- $600ish

- Vintage, 604D

- Cheers! Yes there may be better and bigger deisgns for all out bass reproduction but I've heard these and love them. Still some time off finishing them and away for the holidays so I'd anticipate they'll be done by late Feb.
