question on tuning

[bikerjay]

I've been told that I cant go by the factory FRD information and that I'll need to some software to gather the correct info to start designing my crossovers. My question is, how are you running the speakers with no crossovers? Are you running individual drivers? Wiring everything in a series or parallel to an amp terminal? Last, what app or program does everyone rely on to get accurate information?

There are different ways you can go, for example you could simulate your cabinet response combined with the factory data, and be much closer than you are now.

Another way would be to measure using software like ARTA or REW. This would be especially so if you plan to do polar measurements.

Are you running individual drivers?

Yes.
I keep level low (~1 V) for tweeters and start at 500 Hz.

Did you have a look here:

This tutorial is designed to get you started and tweaking a decent crossover… whether you're new to crossovers, or have built speakers before and are looking for a design method that relies on listening and doesn't require measurements.

The acoustic concepts apply to an active or passive crossover, since the needs of the speakers are the same in both cases. The simple but effective example crossover included here with formulas is of the passive type. With it you will achieve a much higher quality of crossover than possible using basic online calculators, and there is enough explanation to...

Thank you again.

@stv. Twice. And copy and pasted it to a Word worksheet. Very good info.
