      Build the cabinets. Install the drivers. Buy an Omnimic and DATS (or something like that) and do some individual measurements. Export those to PCD7 or WinPCD, Figure out the offsets and let the drivers tell you what crossovers they want. They don't always bend to your ideas too well. Two words: Phase tracking.

        Re: 3way design advice/crossover help!

        I am using the Dayton Audio XO3W-375/3K 3-Way Speaker Crossover in my speakers currently. But I was wondering if a crossover with higher crossover points like the Dayton Audio XO3W-700/5.6K 3-Way Speaker Crossover would sound better in my speakers. I quess the question is What is the general difference in sound between a crossover with lower crossover points from one with higher crossover points? My quess is the lower the crossover points, the lower the speaker frequency will sound????
        I resist using resistors

          Here's the deal.

          More than 99% of the time, the "stock" (pre-manufactured w/no specific drivers in mind) crossovers will not work anyway like you'd want them to. In SOME cases a driver will actually sound better than it will with one of those XOs attached.

          What drivers are currently in your speakers? What's the box like? Did you design it?

            Well the first thing you are going to hear, is that neither of those crossovers are correct. An off-the-shelf unit does not take into account a myriad of parameters and makes assumptions of the drivers that are just not correct. For instance, the crossover assumes the drivers are a static load ie 8ohm when in reality the impedance varies with freq. They do not take into account phase, baffle step, or level matching between the drivers.

            So changing the crossover for one stock unit for another WILL give a different sound but not really better. Better would be to save the expense and have a properly done crossover designed. The difference then will be night and day and will definitely be better.

            Chris, I had a feeling that as I typed thus out, you would beat me to the punch. Lol

              I second these suggestions! In about a year, you'll realize that this is REALLY good advice... and your best chance for success.

              As a side note, it looks as though you built the bass enclosure before picking the woofer. Typically it's done the other way around. You first pick the woofer and then build an enclosure that is optimized for that woofer. (volume of air, sealed/ported, etc...)

              OK, don't get all worried... It's still possible to get good bass, but you now have to find a woofer that will perform well in your exact box, and ignore all of the other good woofers out there.

              This is a fun hobby and once you get started, you'll be hooked. Every design of yours will get a bit more sophisticated as you learn more and more. Best of luck to you. Keep asking questions and have a blast!
