    That's the way to do it, the designer needs to measure the actual speaker to properly design the Xover.

    Hi Buggers,

    For me, not a whole lot about making a good speaker is easy, especially the xover. Pls excuse my little joke.
    I only mentioned it briefly in the beginning of this thread, but I'll be running these speakers down to the Brklyn Navy Yard, where a skilled member of this forum can measure & make an excellent xover for me. I've spoken with him about this, and he willing (he did the xovers on my below monsters)!

    Crossovers are not "whipped up". You are seriously underestimating the work involved. Your best bet is to find a kit that will fit...

    Hello Audio Experts!

    For a last attempt at fast, cheap, & great, I see no reason why I can't drop an RS225 into my sealed boxes, which will even give me room for bracing.
    And the RST28f tweet has lots of overlap with the RS225 (better might be the SB26CDC-C000-4 or SB26STAC-C000-4?).
    So one would just need to whip up a little xover, right??

    PS: Don't make me buy those half-price SEAS Excel W22EX-001 things....

    I did you a disservice. I forgot the Zingers are 1 cu ft. Sad since they are right behind me.

    Thanks Wolf,

    Making a speaker to your design is tempting, but I don't want to fudge it up.
    Finding an 8-inch kit to match my cab doesn't look likely. I think I'll re-foam the woofs, and see if I like the Infinity Ref2 as is.
    Or I could pick some cool drivers & see if anyone would make an xover with me (I can't)!
    Or I could make the Zinger....

    You could likely get away with it, but there will be differences.

    Thanks DJG,

    The Wolf Zingers are interesting. Woofs $24. ea, tweets $26.50 ea.
    I'm not sure if the boxes I have would work well, being smaller & not vented (now), no driver overlap, flush mounting, rounded baffle.... Would these differences need an xover modification?

    The Mark K. RS28a/RS225 MTdesign almost matches my boxes.

    Wolf's Zingers would fit. Probably want to beef up the cab. 8" 2way with Dayton DVC subwoofer. Simple but innovative. Truly full range.

    They are Infinity Reference 2 8-inch 2-way cabs, sealed box. Outside 10.5w x 9.5d x 18.25"h. Walls 1/2" thick (actual), baffle .75", no internal bracing, tweet flange ~3.75" diameter; maybe ~.75cuft interior volume without drivers, I think. Sort-of rounded baffle edges.
    A pretty heavy cab with a sort of light woof, and opinion on the innernet says the tweets can be a little fatiguing.

    How big ARE your cabs?

    Oops, sorry about that little availability problem! I see Meniscus also has them, but listed as "out of stock"
    So much for my "easy" speaker plan... I doubt if there is another 8" two-way design that could use my cabs!
    But the page DJG linked to is good, and should help me going forward.

    The original tweeter was the RS28A and was 4 ohm. They later came out with the RS28F. Both were 4 ohm.

    PE has an "RS28a", not an RST...

    Comparable items in stock: RST28A-4

    Comparable, not identical, not a drop in replacement.
