  • A Late Comer

    All,

    I was obliged to share this in the gallery (thanks Wolf). These have been done for over a year but this is probably the 4th generation I've attempted. They are called the Apaches. I wanted to build a reference 2-channel system for myself and these initially started about 4-5 years ago. The cabs have been re-built three times and I've changed driver choices just as often. However...I think I finally landed on something that I am happy with. This project started when my crossover design knowledge was pretty limited (still is) but the end result is astounding to my ear. Especially considering the cost of the drivers used.

    Dayton RS150P-4, Usher 9950 and a pair of RSS210HO-8 subs on each side. Everything is sealed, about 40-50 lbs of sand in each tower (two cabs per speaker, the subs and upper cabinets are separate) so they weigh in excess of 100 pounds a piece. The tops are powered with an Emo UPA-2 (thanks joeybutts) and the subs are powered with our Dayton SPA2400DSP. Needless to say I have headroom available. The crossovers are external because I was tired of tweaking my other designs and having to rip the woofers out every time I changed something. With the Emo USP-1 preamp I am able to high pass the top cabs so output capability is pretty substantial although I haven't even gotten close to their limits yet.

    I am bias of course, but these are by far the best sounding speaker I have built. The sound stage and imaging capability is unreal and three dimensional. I've never heard a pair of speakers throw sound from front to back or top to bottom like these do. They sound wider than the wall they sit in front of. They are very revealing as well, and fairly sensitive which leads to surprising dynamics. Because of the DSP in the sub amp I have in room response to about 18 Hz with a slight house curve. Even with this boost I have plenty of output with all of the cone surface area from the subs. I cannot wait to get out of this $$%^#[email protected] apartment and get these in a properly treated room.

      Looks great!
      Isn't it about time we started answering rhetorical questions?

        Thanks guys!

        The finish is the same and even. The lighting in that pic is pretty terrible and the pic itself could be better honestly. Doesn't really do them justice.

              I recall this project going through a lot of iterations. It looks like it wound up in a very good place. Nice job.
              Keep an open mind, but don't let your brain fall out.

                Very nice, Matt! I hadn't seen a redo since the AC midbasses were in, so this is quite a change.

                What's the bottom component in your rack? I see source, pre, and amp, but don't know the lower unit.

                EDIT: I forgot you built a chassis for your 2400DSP. Nevermind...

                Later,

                    Just realized the crossover is in an entirely separate enclosure. If I ever do another serious high end build that is in the open I'm going this route. Love it Matt.

                          I am WAY more impressed by sticking to a design, learning, growing, and getting it right. Way to go! I would wager they sound wonderderful!

                              Crossed over at 80hz?
                              There is the new RS-150 4A - is that something you might substitute in for s+g?
