    Hi Pete,
    Jusr refoamed my NLA's and saw econowave mod in google search. The H6512 is too wide for NLA's. PRV has a 5.25 x 10. will 100 x 40 vs the Dayton 90 x 50 dispersion matter? I planned on using the JBL D220i and the (JB) Large Advent XO with PB1 mod if that will work. I could not find an 8 x 8 waveguide to do the zilch mod. open to other options that work.
    Thanks

    I have the walnut ones. With the vinyl trim around opening edge it's 11 3/8" so I could trim horn but it will get into the screw holes or just remove vinyl trim and then you would trim little over an 1/8" each side. The chinese clone is the 8 x 8 waveguide as I understand. I could not find that in my searches, Thanks for the reply

    Oh, that's a lot. The chinese clone is of the 6x12 or you can use the original replacement from
    JBL but not cheap. See MTG's web site for comparisons and mention of the chinese clone.

    You could ask on the big Econowave thread.

    Hi Pete,
    I'd like to build the PZ-2.1 xover, but I have a problem I was hoping you might help me with. I'm almost blind with cataracts and can't see the schematic. Mostly because it has a white background and black writing. The white background is blinding to me.
    Anyway, if possible can you please message me the schematic with a black background? I hope I'm not being too much of a bother.
    Thank you.

    I posted the inverted image here in the build thread. Let me know if you need anything else:
    Which layout do you plan to use?

    How to Build The Minimus 7 PZ-2.1 Crossover

    Here's my build. I bought this pair of Minimus 7W's back in 1987. they have the metal flange tweeter. Components are held in place with hot glue. Hot glue was also used to seal the cabinet in the back by the new binding posts. And here's my BOM. All from Parts Express: Dayton Audio IC181...

    Hi Pete, I was hoping to get your input on my Rectilinear XIa build posted in the main e-wave thread. It concerns the 8x8 wg, which I gather you have experience with, and I was thinking of using 10" pro (cheapo) woofers as my cat destroyed one hours after I brought the speakers home. Any help much appreciated!

    Hi Pete! Did you econowave a pair retícilinear highboys? If so is there a build thread? I have a pair that is shot and might be a good project for one of my high school welding students. Thank you for your time.

    The speakers I have are reticiliniar highboys. I know I’m not spelling that correctly. Lol. The tweeters and mids are blown. I posted them in barter town to give away but someone thought you had econowaved a pair. They must have been mistaken. I wouldn’t mind doing it, given a parts list to order. My woofers could be reformed, everything else was blown by a freshman student. Grrrr!

    I AM Econowaving a pair, BUT they are Bi-amped, they use a waveguide that is no longer available (NLA). No, they were not mistaken. I used all new drivers, sold the original woofers. Why don't you build one of Zilch's designs in it that uses the 6X12" JBL Waveguide that you can get as a made in China clone?

    Build a rough copy of the PSB Stratus Gold in them, you will be blown away.

    Pete B, I'm hoping you can assist with the 10-inch acoustic coupler driver in the Vandersteen 2ci speakers, basically what is the proper wiring for this driver, I see a black wire and an orange wire,
    when I apply a battery to the speaker terminals the 10 inch moves inward and the 8 inch appears to move out even though it has a capacitor inline.
    I've tried both wiring phases and I'm still confused which is right?

    thanks, I'll give RV a call, since I found the orange to positive I'm guessing that is correct? will let you know what RV says.

    answer from Vandersteen,

    The 10 inch on the rear has the black wire to (-) and the colored wire to (+). This would be correct if someone didn’t change the internal wire. The coupler is out of phase with the front woofer as it acts like an assisted tuned passive. Ports and passives always have their acoustic output out of phase with the main woofer.
    Pete B
    Pete B
    He is wrong, but that is nothing new. A port or passive is in phase above box tuning and out of phase below. Anyway, you got your answer black to negative.

    Yes, I think we may have met before. I brought my wife to a meeting where they played duets on a Marantz/JBL setup. I think we spoke by the stairs. I never built anything like BCS before. I'd like to make one for my NLA. I hope to come to the june meeting. Maybe we could talk there.
    Pete B
    Pete B
    Yes, I remember, hope to see you at the June meeting! Sure we can talk about it then.

    Pete, did you ever get or figure out the Boston Acoustics T1000 crossover schematic? I would like to redo mine ( although looking at the photos, it seems like it may be fairly easy to copy, except for the inductors. Any help you can give me would be appreciated.

    Sorry, no I never did have a chance to trace out or measure a crossover.
