altec 807-8z - Page 2

AudioGeek · 15th June 2007, 04:14 AM

ok i connected them up.

they both work.. but run w/o any x-over a little shouty.... yeah i know they at least need a series cap.. but i had them at low volumes.

so will that model 19 x-over relieve some of that shout?

also what would be the spl for 1 watt with the x-over? any BSC comp?

thanks!!

why does the R3 L-pad on the model 19 x-over say 35 ohms? is it 8?

AudioGeek · 15th June 2007, 04:23 AM

if i were looking for a pair of those 416's..

are there any special ones to look for?? 8 ohm i assume.

finally what is the cu ft and port characteristics of the box?

thanks!

Geek--This site has the Altec drawings for the Nineteen cabinet, from them you can see volume and venting. The Nineteen cabinet was larger than previous similar models and made deeper bass. The site also has a great deal of Altec crossover information including Model Nineteen crossover info.

Any Alnico magnet 8 ohm 416 would work, the 416-8B is widely available. Most earlier 416s were 16 ohms and wouldn't work properly with a Nineteen crossover. Later ferrite magnet 416s have different TS specs but were used by Altec in the last Nineteens and are said to sound very good, I never heard one myself.

The Nineteen crossover will most certainly tame the driver and horn. Note that when listened too alone without a woofer all compression drivers will sound lousy.

I'm not sure about that 35ohm pot.

If you decide on model 19 you can get brand new XO form ICONIC.

Here is the site.

I have another sugestion if you will permit.
The Valencia.

My 02 cents worth.

Geek, if you are about to upgrade crossover, have you thought about using active one? Sure, you’d need another amp but if you want sonic improvement, why not.

416-8B is 8 Ohm which is what I would recommend.

AudioGeek · 18th June 2007, 07:43 PM
