Altec 614 cabs w/ 604e Duplex

[Mr. Bissness]

Almost finished these today, still need to set up the amps for a proper demo. But I am pretty pleased on how they turned out.

The 604e have new cones thanks to Gordon Waters with Northwest Speaker Repair

Those are beautiful!

Love the choice of grill cloth - looks great with that paint shade

 

[MrEd]

Excellent stuff here.

 

[Audionut]

Nice! And bonus points for preserving some original 614 cabinets. I don’t think I’ll part with my 604E’s anytime soon, enjoy in good health!

 

[Thermionics]

Are you using an external active crossover for these?

 

[Redboy]

Hah, I was looking for the asking price...

Man, those turned out beautifully! Nicely done.

 

[Mr. Bissness]

Are you using an external active crossover for these?

Yep, I finally get to use these cool boxes I picked up from another HFH member. I just need to take the time to set up the software and adjust the values.

 

[rogerfederer]

i'll be curious to see how much bass you get out of those. best of luck!

 

[Leben]

Nice work on those!

 

[marantzfan]

Those turned out beautifully! I’m interested to hear what you think about the 604’s run actively… I’ve personally never had that experience but I am sitting on one of these boards that I’ve been curious about employing…certainly have enough amplifiers. lol

Dulpex... it's not bothering me.

 

[Jcris]

The plate amps are nice. How much power can the driver’s handle?

Dulpex... it's not bothering me.

I wonder if that's why Mr. Hardy hasn't replied yet?

If only I was good at spelling…if it’s not underlined with a red squiggly, I’ll miss it every time.

Here are the original data sheets, but these now have new 8ohm cones and diaphragms. The sticker is calling them “Super” Duplex, but I think that was only a marketing gimmick.

 

[Jcris]

Can the power output of the amps be adjusted in the dsp filters?

 

[Jcris]

Just checked and gain is adjustable

The term 'Super' Duplex was to differentiate the 604E from the 605A/B which had been released prior (and was not received as well as the prior 604C / 604D).
