I'm wondering if there is anybody out there that has experience w/ both of these tweeters. How do they compare? Is the mt-4115 a lil better, about the same or a lil less good than the peerless? If I'm correct, the mt-4115 is supposed to be a clone of the peerless. Thanks

    I have a pair of the MW Peerless clone tweeters. I prefer the original Peerless.

    Looking at Midwests Ebay listing they say the mt-4115 are 8 ohms with a RE of 6.8 ohms. Is RE the same as DC resistance? If it is the new ones don't have the same specs as my original peerless with a DCR of 8.8 ohms.

    They should have a different crossover point . Am I missing something?

    I'm not sure where you're getting 8.8 ohms for the Polk Peerless, it's actually 7.8 ohms.

    That said, there certainly is a difference between the original and the Midwest replacement, so a crossover adjustment would be a good idea.

    I took the tweeter off of my Monitor 10a and that was the measurement I got with my multi-tester. Would that mean I might have a problem with the tweeter? It sounds very good to my ears but I can't hear much over 10,000 Hz.

    Interesting. All 4 of mine measure 7.8 ohms. What does your other one measure?

    Unfortunately I only have one original Peerless right now. The other is a mismatched RD0198 and I am looking for a replacement (I have a recent post about this).

    I guess if I go the Peerless repro route I will have to get two of them so they match.

    Per Joe at Midwest when I enquired about the replacements back in March:

    "the large batch coming this fall (Sept.) should sell for $39.95 each instead of $44.95 each"

    Wouldn't hurt to contact them to verify this if you want to save the $10.
