Testing Speaker Frequency And Efficiency(SPL)

[John L]

I currently have a bunch of vintage speakers, of which I have no Idea how to match up with each other. I am referring not only to woofers, but misrange and tweater as well.

Unfortunatly, I have no idea as to how to generate a signal that will show a graph, and how efficient that signal happens to be. What will do this for me?

That way I will be able to match up the speakers in order to ge the best system.

Can anyone help me here?

Not sure what you mean, exactly, but right off I would say to keep all models together, that is, use them in pairs.

You might be able to get the specs on most of them from the mfg. or the 'net.

Measuring a speakers specs is, if done properly, a very technical and somewhat time consuming undertaking. The proper tools are necessary as well, and, they ain't cheap.

Some preliminary measurements can be made, but will not tell the whole story.

What you seek requires a software program as well as a calibrated interface, microphone, and amplifier, not exactly an inexpensive setup.

You might be further ahead to try to identify the speakers in question and seek their T/S parameters thru manufacturers or databases on the web.

WT3 from parts express will show impedance curves and most T/S parameters, but it will NOT measure frequency response beyond resonant frequency. WT3 only measures drivers electrically, not acoustically. For accurate acoustic measurements you need "calibrated" equipment.

are these speakers raw unmounted units or enclosed boxes with speakers mounted in them?

[John L]

Some of these speakers are old, from Magnavox, or other brands, the actual maker I'm not certain.

The database does not have anything on magnavox.

And yes, these are raw drivers, not within boxed enclosures. Furthermore, I also need to measure tweaters and mids too, so the Woofer tester is out.

IMO, unless you think these are somewhat rare and uniquely well-performing drivers, not sure it's worth the cost and effort to attain the goal you seek.

But, that's your call.
