Monitor 10 in Rosewood

Picked up a nice set of monitor 10 yesterday that are the rosewood finish. These are earlyish versions with the odd old style grille attachment and peerless tweeters, but still the coated cones and two fuses.

One tweeter is bad (tested and taken apart) so I am in need of one. They have the little hole/dimple.

I will recap as well. There is a light grey mortite type material used to gasket the drivers and crossover/connecting cup so I will replace that as well. What do you guys use to replace that usually. I have some of the mortitie stuff.

    :) Nice loudspeakers.


    Morphologically virtual twins (so to speak) to my Monitor Series Model 7As (purchased in 1978) - right down to the "rosewood" vinyl.

    It's pretty hideous, isn't it? :|

    It may well come to that.

  • Back on point here....

    I am need of one Peerless tweeter if anybody has a spare.

    Also, looking at the crossover, What brand caps have you guys had good results with? I tend to lean towards the 5% Daytons. I see motorhead recommended Sonicaps in another thread. What do you think about just going with an NPE for the 34UF cap? Change the resistors?

    Or two 17uf film caps for the 34uf. Not much sense to put another NPE in there. Polypropylene film caps are much better and will out live the NPE by generations.

    I concur, FWIW. The Daytons (rebranded Bennics) are good cheap capacitors (far superior to generic NP electrolytics, e.g.), but these loudspeakers do deserve better than the Daytons. :)

    Save the Daytons for the Jensen era Advents, EPI "T/E series" -- stuff like that :|


  • What? Install $170 worth of caps into a $200 pair of speakers! Monitor 10's are nice speakers, but they ain't that nice.

    See this is the problem with caps. You've got the Dayton price level, and then typically too big a jump up.

    there's all kind of price points - see www.madisound.com (e.g.) or www.partsconnexion.com

    Dru I agree. I don't think the 10s are worth that kind of investment though many have. You would hear the difference in caps but you'll never get around the 10s design flaw.

    I love the 10s and would love to have some in the garage but they'll never be a main speaker for me.

    Also, while they may sell for $200 or less, you've got a lot more value in them than that. If you look at it as an investment go cheap. If you look at it as personal enjoyment, spend more. The one area almost every speaker builder cuts costs with is the crossover. Nobody sees it and nobody ever thinks about the impact it has on sound. Many don't even believe it does impact the sound.

  • Are the drivers on these supposed to be gasket sealed when mounted?

    I got a replacement tweeter so all is good. They sound very nice, even before new caps.

    Why not? I'm installing $1500 worth of crossover components into speakers that retailed for $900 and it'll be worth every penny.

    Hey Dru,

    Don't mind these guys. They're an easily distracted bunch.

    Armacell is the preferred material for making new gaskets. About $11 for a 30' roll at Home Depot. It worked great on my 10Bs.

    Also, FWIW, I sprang for the Sonicaps in my crossovers and have no regrets. Westmassguy, the go-to expert here, promised me "mo' better bass" with them and he wasn't kidding. I know the M10s sometimes get dismissed as mere party speakers but I like mine just fine.

    Hope all's well with you. Let's catch up some time.

    SO now I am a little confused. I went to start my cap and resistor replacement and I am not sure about what I have here. The two appear to have the same values but different brands of caps. Also, these do not match the schematic for the early version, nor photos of other monitor 10's I can find. Looks more like Monitor 7. ? What do you guys think is going on here? There is a 12uf Mylar and a 33uf NPE. 2 each 2.7ohm resistors only.

    Also a photo of one of the 6.5" drivers.

    $170 would make the $200 speakers sound like today's $800 speakers, so you'd be money ahead.

    To the point of whether the investment is worth it overall given the speaker you're starting with, it may depend on the type of music you listen to.

    I had 7s and 10s in the same room, positioned correctly, etc. Found the 7s were more focused and great / better for most music. To my ears, the 10's really shone on jazz and classical music.

    They just sounded a bit more open and conveyed the wider range of instruments associated with those types of music.
