  • Any other 8 ohm MTM designs?

    Hi,
    I'm on the lookout for an 8 ohm MTM design for music duties. They will be positioned on top of a pair of 15" subs. I've come across these so far:

    Tritrix - http://speakerdesignworks.com/Tritrix_pg_1.html
    Project NEXUS - http://www.hificircuit.com/community...-speakers.319/
    Cinema-8 - http://www.diysoundgroup.com/home-th.../cinema-8.html

    The Tritrix and NEXUS designs are a bit on the small side, don't think they would have enough "oomph" for my liking . The Cinema-8 is a good size and would get loud but not sure pro-audio drivers and compression tweeters will give me the best sound.

    Any others out there I've missed? I'd also consider a good MT in the same price range as the above.

    Thanks,
    Wayne

    I don't know if you can still get the drivers for these, but:
    4i
    Glucinium Amor

    And these:
    Blues MTM

      Thanks Wolf. The tweeters for both of your designs are discontinued unfortunately (unless the PT2C is a drop in replacement). The Blues MTM looks good.

        Nope- the A and C had different response profiles.

        Oh well,

          Hello

          I assume you want 8 ohms as you have an 8 ohm receiver/amp? You might find that it will cope OK with 6 ohm speakers; my old Yamaha RX596 stereo receiver runs a pair of 6 ohm MTM speakers without any trouble.

          In the fine print of the owner's manual, it says that 6 or 8 ohms will be OK. I run a sub woofer from the "B" speaker terminals.

            I have a RS180 RS28 Jeff Bagby x-over MTM that I have used for about 4 years. Very good. The design is buried here somewhere in TT, but it uses the 4 ohm RS180's in series.

              yea wolf drivers for the Blues MTM you can get here, though this is the kit(s) link.


              i personally havent seen many 8ohm MTM projects, other then whats alreay been mentioned.

                Geoff, Your assumption is correct. I have a 6 ohm stable Yamaha receiver, but a 6 ohm design would be even harder to find.

                ontariomaximus, are you sure about that? I found Jeff's MTM design but it uses two 8 ohm in parallel - http://techtalk.parts-express.com/fo...180-mtm-design. I'd very much like for there to be an 8 ohm version somewhere that I've missed though.

                      The LithMTM is 8 ohm, using 2 Dayton ND105-4's in series. F3 is about 50 Hz, give or take. With 2 ND105's, they act like they have a pair of 6"-7" woofers...
                      Keep an open mind, but don't let your brain fall out.

                        Hello again

                        You won't see many speakers advertised as "6 ohms" but they may well be in real life: my MTMs are listed as '4 ohms' on the website but in use are really 6 ohms. I know very little/not much about speaker design and measurement, but if you look at the impedance graphs for any speaker you will see that the impedance graph goes all over the place.

                        My suggestion is to look at the impedance graphs for some of the well known MTM designs and see how they look. As said, I have not had any problems at all.

                        NB the MTMs are Curt Campbell's "Slapshots" for which you will find the details by Googling. I love them, great speakers: they use RS180Ps and Morel CAT378 tweeters.

                        Geoff

                          Just so you know, Mike, it's not okay to link to products of other vendors anymore here at PETT.
                          Just a heads up, as you've been gone awhile.

                          Later,
                          Wolf

                              Does your receiver have pre outs? If it does, you can buy a cheap external amp that can do 4ohm. That would open up a lot of speaker options for you.

                              I recently built a pair of Tritrix MLTL speakers for a relative. It's powered by a Yamaha RV-X765 receiver out to a Hafler P3000 amplifier. Great sounding budget setup.
