  • Jim Griffin's Aura T-line 2-way

    About two years ago Steve Henry was kind enough to send me plans for Jim Griffin's T-lines useing Aura 3" drivers and a Hivi Tweeter. I made a mistake and they sat in the corner till two weeks ago.

    Big thanks to Steve and Jim. Here are some pictures.
    Nice sounding speakes too.

      DUDE, your avatar.... It rocks! I think it deserves a fist bump or something.

      I'll bet it's a very nice-sounding speaker. I like Jim's stuff.
      Isn't it about time we started answering rhetorical questions?

        Glad you like them - people are still amazed at the amount of bass this little ML-TL makes. Very nice work.

          Those look great, to bad I have yet to get out and listen to any of you guys speakers yet. I'm going to do my best to make to the IWOA event. I hope I can have my speakers done by then.
          I have always liked it when little speakers actually have some bottom end without sounding boomy or distorted. That's what led me to build my lil sub for my computer speakers.
          Again great looking speakers and I would like to see the build on these if possible.
          Thanks ,

            Steve actually emailed me the design a while ago. Oops

            Not sure what the square "opening"? is on the back and if the port hole has any depth other than that from the 3/4" MDF.

              The square opening is for the terminal cup that Jim specifies. It will give you just enough room to get the crossover into the enclosure. Jim also gives the PE part # for the right port tube. These items were in email portion of Jim's instructions. If I failed to send you this info, I apologize & will forward as soon as I get back from a business trip.

                No problem - I'm glad to get this info in one place.

                  The new Aura sound 3" drivers spec out different then the old ones I used, so they may not sound the same. Maybe the new Dayton 3.5" will work. You may have to ask someone that knows.

                    That would be Devin Townsend. He has much verried and cool music some that is not for the faint of heart and some ambiant and pop metal. The recording quality lacks but he has got better at that over the years. I realy like his Ocean Machine cd. You can check him out at HevyDevy Records online. The song writing is top notch in my book.

                      I heard the originals, and directed Steve in that direction. I must say, the TN25 sounds very 'sweet' in that design. Getting bass into the 30's from 2 3" drivers is also a very cool thing!!!

                      I really like how Jim 'flushed-in' the tweeters. He used a sticky-back Foamie to both seal the midbasses, and flush the tweeter. Makes it really easy for those stressing the odd-shaped cutout on the TN25....

                        Wolf, some of the old emails that Steve sent me had you in them. Yep, that HiVi TN25 sounded good. I had second thoughts about it after seeing some distortion plots but they sound fine.

                        Later Wolf. Hope I can make it to Iowa.

                            I'm planning on buying these to build Jim's MTM MLTL. Anyone who knows [Jim G.?/Steve H.?] - are the specs for these the same as the originals?

                              I believe they are the same. The PE version is a slightly different. And at the current price at Mad, I'm going to buy some more myself.:D
