Network

Could we use a JBL network on a Altec A7 for example.
Network N4638 500 HZ.

With 8 ohm drivers, why not?

I tried to find a schematic with no success. It appears it may have a bit of HF eq/compensation built in.

I was looking at their parts department,apparently you can order them . They are not that expensive. This is the model from their cinema 4000 series .I'll try to find out what impedance it comes with.

Unfortunately it's 4 ohms. Theres got to be a model with 8 ohms

It's stock for the 4675C system(2446H HF and tandem 2035HPL LF). There were other driver and impedance options for the 4675C.

I have to correct myself as this is a 4 ohm LF load, and the spec sheet gives a nominal impedance of 4 ohms. The adjustment is for HF alignment according to the spec sheet.

Honestly not sure what the point would be, unless having the JBL name is important to you. Likely designed for specific drivers, so a textbook unit from Martin sound might even out perform it. And I really don't like electrolytics even in the LF. That's just a cheap unit that says JBL on it.

I don't like the electrolytics either. Any way JBL Network have different impedance out like 16 for highs and 8 for lows. I thought I could buy something new to replace altec N500 and N 800 for either the A-7 or the Valencia.

I was expecting to hear that those particular networks were available in quantity for a very small fee.

You used to be able to get some insane deals at JBL "tent sales", sometimes things like those networks could be purchased for little more than the value of those 'lytics.

Those are such textbook 2nd order networks, why not just scratch build them?

I want crossovers that say Klipsch on them!!! . (ducks to avoid getting hit by the barrage of whatever you guys could grab and throw) :D

The horn eq will be set for the 2446 and a big bi radial. Yukky.
