    Thank you for such a quick answer - I assume these are sealed, as the 830657 needs a very large vented box.

    These drivers are still around in bulk and these speakers would be amazing value; of course, WAF would be a factor in using them: unless the finish was as good as yours, it might be a challenge to move them from the garage to the house!

    Cheers

      They are vented! - a slot port 7.75 inches wide, 3.75 high and about 12 inches long.

      The drivers didn't model very great either sealed or vented (xmax problems either way).
      I gambled on vented and it turned out great.

        Thank you

        A set of these, even in $A, would cost around $350 in parts, plus MDF: amazing value!

        I've used the Peerless 830656, a nice speaker for the money, but few projects use the 830657, which seems a shame; so it's very interesting to read about this one.

        For a good bass test, try "The Real Me" from The Who's 'Quadrophenia'. Great bass line and Moon beats hell out of the bass drums.

        Happy listening!

          Hi All,

          Great Project!, it got me interested and I'll get a box of these delivered tomorrow, I'm new to building speakers and I want to learn to design them in a good way, definitely this post helped me a lot, all those measures taken and importance of them, etc. All great info for a newbie like myself.

          If I want to do a similar exercise with my speakers would DATS V2 help? Anything else you can suggest? , I know investing a hundred bucks in the tool will take the deal factor out of this but, again, I think I will continue doing this for a long time so definitely the tool will pay by itself in the long run .

          Thanks in Advance!

            Hi Alex -

            My personal preference is to use LIMP and a very cheap box to test impedance. There is a "sticky" topic in this forum that details how to do that.
            DATS is very nice, but I haven't felt a compelling need to buy it.

            You will definitely need a microphone and software to measure frequency response. the Parts Express EMM-6 microphone ($50) is darn good, and can be
            used with ARTA (shareware) and Holm Impulse or Room EQ Wizards (both freeware).
            Omnimic ($300) is used by many of us, and is pretty great.

            You should also become proficient with using WinISD and/or Unibox (Excel) to model bass/box responses. (both free)

                I've always liked the look of speakers with multiple woofers. These look great. How do they sound compared to some for the other speakers you've built, Donradick?

                  effortless, reach very deep for my (moderate) listening levels.
                  I think the multiple woofers blend into the room so the bass level is very even, you don't get floor bounce cancellations that cause uneven responses.
                  Although these Peerless drivers are not engineered for low distortion, the perception IS low distortion because each driver doesn't have to work hard.
                  The mids and highs are clear, but obviously not in the same league as Mini-Statements, for instance.
                  Still, my Mini-Statements are in storage, and these are in "production" in my living room.
                  There is a "you are there" quality that is very engaging.

                    I fully agree Don. I found this as well when I built my WWMTMWW project. Even at medium volumes you could barely see the woofers move. The "you are there" quality is difficult, if not impossible, to duplicate with a typical 5" or 6" two way. Hats off to your cool design and build.

                    • Thank you for the review. How do you these speakers would do as a center channel, with the tweeter and the two mid woofer moved to the center of the baffle? I'd like to build them as LCR speakers for my dedicated theater room.

                      • I should work pretty awesome as a CC with the MTM moved to the middle of the baffle.
                        You will have some pretty awesome HT output, but you will want to HP these fellows and use some beefy subs for full FR coverage.

                            Hi Don,

                            I took a look at this approach for creating the box and use LIMP with it but as I understand it, I still need to buy a Sound Card for it right?
                            I don't think the ones that come with my laptops will do the trick, am I overthinking?

                            Thanks Again!

                                Alex and mr DJ -

                                You can definitely just use the sound card in your laptop. That's what I've done for 10+ years.
                                If you use LIMP for impedance, you don't really need DATS, but that application has some nice "bells and whistles".

                                DJ - not sure what your question refers to.
                                There are 3 or 4 main tasks:
                                1 Get driver Thiele/Small parameters.
                                Usually these are listed on the sellers page. If not (like these "A" buyout drivers), then you will need to use DATS or LIMP to measure them.
                                2 Model the box "bottom end" using WinISD or Unibox.
                                This tells you the shape of the bass region frequency response and shows if you have problems with XMAX or PORT chuffing.
                                3. Build the box, mount the drivers. Measure frequency response.
                                4. Measure driver impedance in the box with LIMP or DATS

                                Use the impedance and frequency response files to simulate a crossover in Passive Crossover Designer (PCD) or WinPCD.

                                Does that answer your questions?
