Default Speaker Workshop: the best and how to use it?

Life is too short to drink bad wine? Probably.
Life is too short to not design and build a "Class A" audio system? You bet!

After much audio & diy audio surfing, Iím just about to start a (hoped for number of) speaker projects, starting with modest components (cheaper Peerless and Seas) in a 2 way as quick training wheels, and say by latest end of year, the real goal of a Linkwitz Phoenix based/ thylantar type updated active 3-way using eg ribbons & PHL.

Iíve searched on
design AND software AND free AND crossover

It seems that Speaker Workshop is the best shareware.

IIRC a conversation 4 months ago with a SW user, to get 3-way, you need to cascade. Apart from that, he was satisfied.

Anyone comments, suggestions, tips?

TIA

Default a black art?

So how do you guys or gals do it?

Pick the Hz ok, but levels, shelves & notches

Not really a black art?

Speakerworkshop is not the best software but the best <i>free</i> software

There is a good tutorial on the web site where you can learn the design process and how to use the software.

I recommend that you build the Jig before starting any project. This will ensure the repeatability of the results and the coherence.

If you have all the parts, it take 2-3 hours. It cost me 20$ (CAD) because I have used good RCA jacks and other stuff.

Yes my 2 threads today: on xo design, and testing do overlap Ė my apologies,
OTBE, itís better if the approach used is integrated (Iím probably too tired/ one too many beers, and while my aspirations are high for an active 3 way by year end, Iím a newbie).
So summary:

Are PLLXOs worthwhile?

Does Speaker Workshop allow you to design shelves & notch filters?

Does SW handle only normal Passive filters?

Can SW accept the results of a speaker testing rig?

If not, possibly for a 2 projects away, whatís the next level of software up, that can use results?

What is the recommended speaker testing rig, either Elliot or http://www.gti.net/wallin/audio/jig2/jig2.html
and approx time and cost to build?

TIA

Default SW accept its output?

Thanks FranÁois.
While writing my last post, you answered one of my earlier Qs.

Can SW accept the results of this rig, is there an intractive/ iterative fast tracking method?

The version 2 of the jig is the result of comments received by Eric Wallin from the designer of speakerworkshop. So, in my view, this is the best jig to use with speakerworkshop because it is designed for speakerworkshop.

I'm just getting into SW myself. If you go this route, I have a couple of suggestions. First, definitely build Jig II. Second, the instructions on the Wallin site on how to connect and test the jig with the software are a little outdated unless you have an older soundcard that will put out enough power to drive PC speakers. I have a SBLive soundcard and I've run into some problems due to this that could have been avoided. If you want more info, let me know. good luck.

Default Questions about using JigII

Tim, I just built the JigII and have run into problems as you suggest. For one, my soundcard's (SoundMax) output wattage is low compared to the card Eric uses. Have you found any more instructions on how to use it with SW?
