X-over software recomendations

[pjpoes]

Hey I'm looking for some decent crossover software, and I'm curious what people use. I have seen many a DIY site where people talk about modeling the response of a x-over, and I can't seem to find any that does more than look at the perameters, and give you a basic layout. No response graphs. Also, software that can model both series and parrallel crossovers would be nice.

I know leap is liked, but I think that is too expensive for me. Something cheap or free would be best.

Basta is a very powerful tool.
Maybe Boxsim is also a good choice

Is there any databases for driver specs. I mean, lots of people here measures speaker drivers all the time, is there any place I can download the SPL and Impedance files they make when they do it. I'm looking for FRD's and ZMA files. I know its best to measure yourself, but it would be nice to model speakers i don't yet own but would like to play around with.

Google is the best shot there. Try to get specs from manufactures or large distributors.

I have always done crossovers "long hand" though will cheat using lookup tables. Getting rusty at it now. Everything here is full range.

SpeakerWorkshop can do it, and it's free. Has an historic reputation of being difficult to learn/set up, but that's been overcome by (1) a user manual writen by an enthusiast and (2) many users worldwide who can help online and (3) RTFM!

Edit: I see you can't say Read the Freakin' Manual here...

is there a software that can help to design line level crossover?

What about opinions/recommendations on software to design filters in general (for passive/active applications)?

I'm thinking of using active filters for attenuation/gain in conjunction with digital filters for time/phase aligning drivers, crossovers and bass digital room correction. I believe this would maximize the s/n ratio of the dsp because I am not using them for serious attenuation. I am more familiar with the digital side than the circuit side.

SpeakerWorkshop also has a facility for generic design of active filters, but does not include the power supply or pin connections of the IC's (you'll have to look this up; there are so many op amps to choose from). Linear Technology offers a full SPICE package for free (LTSpice?), which is very well regarded. It is often referred to in these forums. Search the forums and/or go to LT's web site.

Understandood.

The SPICE software was pretty much what I was looking for. Another question though, I have no experience in circuit design, are there any additional circuits included that would be wise to include but do not necessarily affect the signal directly?

Also anyone have a link to the special speaker workshop documentation written by a third party?
