  • A few basic questions

    I'm in the middle of my first attempt at DIY audio. I'm building the Tritrix MTM TL with the cabinet kit from PE. I just have a few beginner questions.

    1. What's the best way to mount the crossover? I'm going to mount it at the bottom of the TL so I can access it if I need to. I can't use screws because there's not enough room. So what's the second best way to secure the crossover? Double-sided tape, velcro, I think I saw someone mention RTV?

    2. Do I need a gasket in between the drivers and the cabinet?

    3. Do you think that I will need speaker spikes if I'm using these speakers on carpet?

    Thanks in advance for any advice.

    1. Get some "industrial strength" velcro.

    2. If the drivers already have gasketing material of some kind on the backs of the flanges, you won't need to add any, otherwise you will.

      A good alternative to gasket tape is to apply a thin small bead of black pvc caulk. I get the bathroom type at lowes in a tube that has a screw on top so you don't even have to load up the caulk gun just squeeze the tube. Let it dry overnight then attach your driver. Makes a great seal can be applied relatively thinly and a tube of that stuff lasts a long time. If you need to remove the driver it stays on your cabinet.

        It would be advisable to put weight in the bottom of the cab or build bases for them along with spikes! The cab by itself, once everything is installed can a be a tad top heavy and easy to tip over! I made solid 1 1/2" MDF bases, gluing and screwing two pieces of 3/4" together. Makes for a very heavy base and keeps things upright nicely! Spikes or some kind of decorator wood pegs will distribute the weight and make them stable

          Thanks for the advice guys. I'll use velcro for the crossover and be sure to use some sort of gasket around the drivers. I am planning on putting sand between the cabinet and the waveguides at the base of the cabinet to hopefully make the speakers a little more stable. I might add some spikes then as well. Great looking speakers BTW jerryanderson.

            I though you were putting the crossover at the bottom of the line? I wouldn't put sand inside the box, even if in bags. Build a base and weight that if you need. Geometry/volume matter on the MLTL.

            I was so much older then, I'm younger than that now.

              I agree with some of the other posts! Putting weight in the bottom of the cab and trying to mount the x-overs there as well is could cause some problems for you! I'd rethink your stategy abit

                But if he put the sand INSIDE the waveguides, it would probably work. Depends on how much you can reasonably fit in there if it would be worth it though.

                  This is what I was planning on doing. Putting the sand inside the waveguides which is just empty space once the cabinet is fully together. I don't know how much it will help because I can probably only fit a couple of pounds worth of sand in each speaker. But I already have the sand and I don't think it will affect the sound so I'm going to try it. I could always build a base later if I think they're still too tippy. Thanks for the feedback guys.

                      Thanks Curt. I'm going to mount the crossover on the bottom of the angle bracket with velcro. I like the accessibility in this position. And I'll definitely keep the outrigger suggestion in mind if I think stability is an issue. I made a lot of progress today, I can't wait to hear these.

                        Is this OK to use as a gasket for the drivers?

                          Sure, lot's of ways to get this done. That will work fine.
