    Re: OS MTM Build (And So It Begins...)

    Yea, that was another thing. The vinyl is so thin every imperfection shows through. I also thought I had the edges of the wood pretty smooth, but it still shows a little.

      Re: OS MTM Build (And So It Begins...)

      Just for those who would like a size comparison I took some pictures of my Classix II's side by side with the OS MTM cabinet. I just assembled the cabinet and it is being held together by tape.

      The OS MTM is a tall, skinny dude compared to his fatter cousin. It will be interesting to see and hear how they turn out. My son and myself will work on the cabinets tomorrow and hopefully have them glued up. I still need to order the parts, but I should get them in the next week or so.

      Stay tuned...

        Anything that seals the wood and creates a smooth surface will help the vinyl stick. The shellac based products are great because they dry fast and are thin. Water based Poly would work. The cure time is a bit longer and the build is thicker so runs can be an issue

          Well now speaker number two is built (except baffle). And I am not liking the laminate. I may pull the laminate off, sand, use some of my polyurethane, and use some body filler and try again on one of them. The larger flat pieces aren't so bad. Its the small strips I have on the edges like edge banding that are the problem. To be honest, I think it was easier making the cabinet from a good furniture grade plywood and finishing it then it has been using the laminate. The laminate goes on easy, but if it peels up on the edges then it isn't worth it.

          So I will try your guys suggestions above on one of them and see how it goes.

          Wish me luck...

          Thanks for all your suggestions!

            How much could one possibly save by using laminate. sheesh. I think furniture grade plywood, what my baffles are made of, showing no edges, is the way to go. Otherwise Id duraflex the MDF. Just my $.02

              Actually my Son and myself are new to cabinet making. I used to be a framer and roofer 25 years ago, but cabinets are a new thing for us. So when PE had a sale on the vinyl black ash stuff I thought we would give it a try. I am thinking of giving the Band-IT veneer a try next to try our hand at it, as I am building the OS CC next.

                Re: OS MTM Build (And So It Begins...)

                Well its official. I just bought some Bubinga veneer off of ebay for 22.00 and free shipping. I guess we will strip the vinyl off and make the speakers ready for the veneer.

                Does anyone have any words of wisdom in regards to working with raw veneer? I have never used it before.

                Thanks,

                  Re: OS MTM Build (And So It Begins...)

                  Today I got the crossovers finished and I mounted the drivers in the baffle. I used clamps to hold the baffle on since the cabinets are not finished and played some music through one of them. I did a side by side comparison between the OS MTM and my Classix II's.

                  Listening Impressions:
                  The OS MTM had a lot of detail and was just as loud as the Classix II. I did notice that the Classix II went lower then the OS MTM could. I beleive setting the MTM up as a "small" speaker would be advantageous and let everything south of 80Hz come through the sub. I really felt where the OS MTM shined was in detail. You could hear things that my Classix II would kind of "wash out". I still prefer the Classix II for rock/metal type recordings. But if you want to hear more details the OS MTM is your guy. I do say they are worth every penny that I spent for them and more. I would not be afraid to use these as mains and/or surrounds in a HT system at all. You just want to make sure you have a good sub for the low end.

                  Another great aspect was that they do blend well with the Classic II's. My idea was that I would use the OS MTM as surround speakers, and I think they will do nicely!

                  Now all I have to do is veneer the cabinets, time to get back to work... ;)

                    Don't use contact cement. Coldpress w/ titebond will work, but a specific coldpress glues will be better. www.veneersupplies.com can help.

                      First I would like to thank Leroy R for all his help. Lee lives in my area ad offered to help me out a while back. Lee was able to show me how he veneers and how to finish the speakers. The results that we got I think are amazing. Below you can see some pics of the cabinets that were veneered a week ago. the last photo is a side with the first coat of wipe on poly.

                          I just applied the 6th coat of wipe on poly. The cabinets just keep looking better and better with each coat. My wife came home last night and was very impressed. She wants me to build some more now for our bedroom because of how beautiful these are.

                          I will post some more pics as soon as they are complete.

                                Well we are down to the home stretch now. We have certainly learned some leasons doing this pair of speakers. I will outline some of them below and then include some pics of them.

                                1. I hate MDF! The cabinets were ok but the baffle sucked. I was going to paint the baffle, back of speaker, and the bottom black. I sanded smooth with 220 and put a coat of primer. Sanded again, repeat. I got to 7 coats and they looked hideous. The round overs kept looking and feeling fuzzy. I would sand smooth, prime, and when dry it looked and felt fuzzy. I asked those I knew who were in the know and got some advise but it didnt work. So I sanded them down smooth, sprayed some 3M glue on and laminated the baffles with that Dayton black ash vinyl. Now they look nice and the laminate is sticking.
                                2.I love plywood. The first pair of DIY speakers I ever built were Paul Carmody's Classix II's. They were easy by comparison. I sanded, stained, repeat. They look awesome. No sweat, no problems.

                                I think they came out looking fantastic. Leroy R had a lot to do with that. He helped me out in the veneering and the Bubinga I got from ebay looks beautiful. When my wife saw them she was flabbergasted. Many hard long hours went into making these puppies. Hopefully they will last us a long time.
