    Here's a filter I made a while back for a mtm. The two woofers in parallel should be 4 ohms like your driver.

            Oh, sorry! Just realized I linked to the wrong design! This is the one I meant: http://projectgallery.parts-express....o/texas-flood/ Same woofer but 8 ohms so adjust the part values as I said before.

              Adam -- here is my design for a RS180 MTM with a Vifa (Peerless) DX25 tweeter. Can play very loud and clean if desired, suitable for Mozart as well as Van Halen.
              Ping me if you need anymore information. IIRC, I put this into a 1 ft^3 box.

                    OK this is my most recent attempt...


                    How do I smooth out the spike at around 1200 hz?

                      I don't really know how to read the other charts so I'm not sure if they are good or bad.

                        No, "WAYMAN" built a tower version.
                        My large "Bookshelf" is about 22 inches high IIRC

                              Is it sealed or ported?
