Speaker design master Curt Campbell has created several dream kits for the audiophile, including the TriTrix. Featuring two 5.25″ Dayton Audio woofers and a single tweeter in MTM format, the final product has an easy, 8Ω load that can be used for audio or home theater systems. The transmission line kit includes precision-cut MDF for making the cabinets, which came together for me with a little wood glue and some clamps (I used five to make it easy on myself). With instructive online manufacturer videos and priced at only $259/pair, these speakers blow the roof off any competitor.

  1. JDS says:

    I’ve made the vented version (as opposed to the TL version shown)…they sound very, very good for a $200 set of speakers. however, there are other designs available that will easily surpass them ….if you’re willing to spend >5X the money.

    1. I love the TriTrix speakers that I built. I also have the Seas Idunn speakers that we reviewed and think they sound fantastic.

  2. Alex says:

    Is it possible to use these with a 6Ω receiver? Or will that overpower them?

    1. Jerrod says:

      This is an 8Ω cabinet. Plugging it into your receiver will run your receiver at 8Ω, not 6Ω. Your receiver’s rating of 6Ω is the maximum Ω load it can take, not its constant output. The speaker determines the amount of Ω involved.

      1. D. Stark says:

        No, 6ohm is the MINIMUM impedance his receiver will allow. It is perfectly fine to go higher.

  3. Dave says:

    The 6 ohm reveiver will work fine.

  4. This isn’t a product review or even an overview. It’s just somebody saying “I bought this”.

    That informs or helps…. No one.
