    In post one he talks about building a tower. Build these into a tower with the tweeter about 33" off the ground, and you will probably be very, very satisfied with them.

    I may try a pair of these.

      Interesting...

      All the talk about tower this and that, made me look into modeling a 30L vented, and came up with some surprising results.

      First, the graph. F3/6/10 of 40/37/35.



      Excursion at 30 watts



      If a guy can live with the hump centered around 90 Hz (and it isn't toooo objectionable) and the inability of the system to play super-loud, I think venting could end up working really well.

      Below tuning, there is plenty of cone control - most vented systems will pop out at just a watt or two below tuning.

      Interesting. Port it up, Ken.

        Cool build and design philosophy you have there.

          Line the enclosure with a bit of mattress topper and that hump should even out as well. These grs drivers are looking like fun to play with!

            Lowell Simpson will be picking them up on Monday to give his impressions, and Nick will hopefully be stopping by this weekend for a listen as well.

            Lowell is willing to get these into the wild along his route, within reason of course. Hit me up if you want them for awhile, and I can check with Lowell or whomever has them at the moment to see if it is feasible.

            I believe Chuck has second dibs at the moment.

              Nick had them most of the weekend, and Lowell just picked them up this afternoon. Hopefully they both have good things to say about them!

                I wont get a chance to listen to them until Thursday. Maybe next week will get me near Laporte. I will let Chuck know if so.

                  We will get it figured out Lowell.

                    I have nothing bad to say about this build . Listened to music and a movie on these with a sub in stereo mode and thought these sounded great! I noticed when listening to some 70's rock that , in some tracks the low end was a little more pronounced ( sub disconnected ) Im guessing this is due to the production/mixing of the content? Everything sounded neutral to my ears and nothing stood out or killed my ears for the couple days I had these in my grubby mitts. I think I read a post where someone might build a tower version , this could be another neat build too and think they would be worthy of a try. All in all , hell yeah we enjoyed these very much . Curious what others think. As always , nice clean build Johnny ! Kudos and thank you for the offer to listen to these in house.

                    I was listening to these off axis at home, but listened to them at JR's place, mostly on axis and both locations were pleasing to our ears

                      Thank you for the kind words, Nick - the slight bloat on the bottom end was probably due to the 1.0 Q design emphasizing the 70-90Hz region.

                        I have all the parts and hope to be able to build a tower soon. JR gave me a few pointers on the tower design and looks to be a very nice build.

                          Seriously. If you want to play Lorde, Royals, you'll need a sub. If you want to listen to music, these are pretty nice. They are afterall sealed speakers. They do vocals really well. Johns integration between drivers is really well done. I Recently bought 'Linda Ronstadt Duets' and the first few songs have strings, ya know, cello, violin, and they sound really nice with her deep voice as well as her partner.
                          I don't remember what tweeter that is, but I think I like it.
                          I will get these to Chuck this week.
                          Thanks John.

                            Just thought I would give an update for anyone wishing to build these using all PE parts. The buyout coil (269-303) will work with a quick un-wind procedure. These are not glued coils, so when removing the tape - keep your fingers wrapped around everything or it will go BOING all over your desk and cause a few cursewords to happen. Have some tape handy to wrap it right away, as well. You can't say you haven't been warned ;)

                            I measured two of them at 2.37mH, and removed 43" from both to get to 2.2mH, at 0.86ohm DCR. These will work very well for this speaker.
