    I have to admit one major improvement, setting the tweeters not only made the install look professional, but the bass came alive. I must have had air leaks which is very likely since I didn't use a seal until I made the final recessed installation.

    I'm close to getting rid of the equalizer. I'm not far from neutral on all frequencies, still adding a little bass and reducing the mids. These tweeters are awesome. I look forward to RDO-198's in the sevens.

    The RD0 tweeters are a huge improvement over the SLxxx series. Not many manufacturers support products 20-30 years old but Polk R & D'd those to improve them while still making them electrically equivalent.

    Awesome. I hear the Blackhole 5 mod helps reduce the shouty midrange at louder volumes.

    Will, you've been exceptional through this process and I commend you. You are a rarity in these parts and it's been a real joy watching this come to fruition.

    As far as the flaws with the monitor 10, don't ever take that as anything but a fact. There is a reason speakers are no longer made that way. Speaker design was still rather rudimentary in those days and we have learned much since then. Make no mistake that they and all the vintage polks are still great speakers due to the voicing and build quality. Some are still even end game type speakers for many in a world of million dollar speakers.

    Will, I have no idea how those sound but the wood working looks fantastic and flawless. Over at AK a similar project was proposed ,this time JBL studio monitors and to be mass produced. This guy had no idea what he was getting into and to a man shot him down w/o mercy. Here you weathered the verbal storm, changed and perfected your design features and took some advice along the way. Most all here say SDAs can not be reproduced w/o any monetary returns and not worth the effort. Here you take the monitor line and looks like did the M 10s some justice. What needs to be done if you even care is to meter and do an a-b blind test w/ stock originals and see which bests out. I never heard 10s but do own '78 M7s w/ x-overs redone by Dave. Did you finally tally up what that set cost you with not even counting your labor or sweat equity ?

    MDF, veneer, crossovers, drivers, tweeters... $615. But probably more like $750 for all new drivers...

    I would love to do a side by side blind test with an original. If anyone would like to donate a pair, I certainly will not object to thoroughly testing.

    Very well said. I'd nominate this thread to become an announcement or sticky. There is lots of good information, answers to common questions, and good feedback from @willwilly. The speakers do look amazing, "a most excellent job." I do hope you veneer the M7's, possibly in something exotic. The 7's hold a special place in many polk and non polk fans. But its not my money, so I know how that goes. If you wrap them, I'd still vote for something stunning, but not too crazy.

    I'd hate to take you down the rabbit hole, but if you can find a decent set of separates, or mostly a good separate amp, I think you will be amazed at the bass difference it makes. Sometimes the bass doesn't seem much louder per se, but it has much more impact and all the music is more detailed. As I mentioned previously, you start hearing things you may never have noticed before. It becomes even easier to isolate different sounds.

    Most of all, I'm glad things are turning out well, and you're seeing the fruits of your labor and the advice. Thank you for the thread. :)

    One small question, while you were building these fabulous cabinets did you also seal them internally? You mentioned air leaks somewhere in a past post. PS they look fantastic, great work. Enjoy the fruits of your labor.

    When playing around with a rescued pair of 5's, I have to admit the lobing issue from side by side drivers is evident to me now. The tens sound much better but the "imaging", using this word lightly since I'm just starting to recognize what it is, is muttled compared to the fives.

    I look forward to my sevens.

    The road to enlightmenment begins...

    EDIT: Like I said before, the M10's are good speakers, just not great. I'd gladly own another pair if the right deal came along. If you just want an awesome tonal signature and don't care about the stereophonic qualities, they are a top contender for anyone.

    Conclusion:

    I have had a wonderful time with this project. It has inspired more ideas and other possibilities.

    My initial idea was to build a nice pair of speakers I fell in love with many years ago. A familiar story.

    I have played all my music through these twice. I have hit my favorites many times more. I have compared them with other Monitors: Played with sub woofers, surrounds, receivers, equalizer...

    After all that, I am very comfortable knowing I recognized a good pair of speakers in the day. I compared everything to them, never owning a pair.

    But,

    What I have learned, Monitor 10's are great speakers, the speakers you roll out for the 4th of July patio party, Barn dances or Church socials. Great for the shop, Jazz, Piano, Classical, Pop, ROCK, They will project! I have mine with a vintage Polk sub, A simple integrated 100w receiver in a high ceiling shop, Perfect for rock'n while you're drin... working.

    But I've been ruined forever. Ruined like the day a friend made concentrate on the laugh track most sitcoms use, letting you know when to laugh.

    Imagining is lost in 10's, it's there but nothing like single driver Monitors. They would be fine in the living room but for real sit down, good listening speakers, I can do better but stay Vintage.

    Live and learn. On to 7's

    Will I am,
    Thanks for bumping this thread. I had not seen it previously, and so I binged on it this morning. Thoroughly enjoyed all of it. Your speakers are fantastic!

    Learning from the experience of others is perhaps the most difficult thing to accept and accomplish. You succeeded 100%.

    Will,
    I saw these Monitor 10B's on Craigslist Atlanta this morning. They have original boxes and the stands. I don't remember your talking about stands for your "masterpieces".

    I have yet to make stands since my speakers are mounted in my shop about head level. A relatively simple build that I plan on doing for my M7 set in the house, now my favorite speakers...

    I hope to rival your build with my rta15tl. It will be a long while before they or completed or revealed but they will most definitely be one of a kind.

    The custom woodwork is 1st class. If and when I get a set of 10's I will try an inductor on one of the MWs just like I did for the TMM project. It got rid of the lobing. Kudos.

    So I'm thinking about selling these clone M10's to fund my next project. Anyone interested. Not sure of a price. I know I have more than $800 in parts, wood... Not including labor which is a contribution for most of my projects.

    This was one of my favorite builds to read about, and I am still amazed at the wood work. I have no idea on a price. 10's get less love. :/ Others would know more.

    I would be really intrigued see what these would be like converted to SDA's. A crossover from a CRS / 2B? would be needed and I think new drivers as well. Someone else may know more about the cabinet size and how the PR would react. I don't recall if the 10 and CRS share that as well. That may bring new life to these for you, and more interest if you decide to sell them.
