    This is true but only in one dimension. Top and bottom are still flat. What is the height?

    19.5" ID. I figure one dimension is good enough especially since there is continuous expansion now.  Sloping the top is more than I care to try.

    For some truly slamming drum action, the Viking group Heilung is my go to for that. This sounds epic on my system.

    OK now that works. Teufelstanz is another group in that vein.

    Would not having a rectangular back chamber for the driver be so bad a detriment that it makes the angle cut on the front absolutely necessary?

    Square corner stronger than pointed one. Also if I do elect to stand it up on edge I like the square corner look. I doubt the shape of the back chamber amounts to much as long as volume is there.

    Looks interesting, though I liked what you did before, except I'd shorten the primary run as needed to put in a LaScalaesqe snout which continues the expansion otherwise truncated by the final parallel walls, if stated that way makes sense.  In fact I've been mulling it over for myself...

    There is no way to do that without losing throat distance which then reduces bass and bass was the whole reason for building this. I have no final parallel walls in this version just continuous expansion from beginning to end.

  4. Got to thinking the other day about how to squeeze more out of the envelope and Claude's Quarter Pie idea and came up with this.  Basically the same travel as the S-MWM but consistent expansion  whereas the S-MWM does choke that off at the end. Have to get Claude to validate this reasoning and if it will do what I think it will should work very well. Simpler to build and will be at SWAG next year if the concept is valid. It would be cool to go down to 20hz with a single fold horn. This would also lend itself better to standing up on one edge and taking up less floor space. My understanding of deeper bass is that it is kind of omni-directional and that hard floor surfaces right in front of bass bins can cause problems. So my reasoning is that if I lay the plenum side on the floor it will then be aimed away from the floor eliminating some of the floor reflections and saving space. Another thing I am thinking of here is a comment by Roy where he said he kind of thinks about sound travel like water if I remember right. This variation would allow me to use a curved deflector on the back side although to maintain constant expansion it might require shortening the plenum. Personally I am leaning towards maximum plenum length and leaving it like it is right now unless I am told otherwise.    @ClaudeJ1

    You are entitled to go on record, but everyone should realize, there is a very high probability you have likely never attended multiple RMAFs, nor have you, and many others,  likely ever heard these tube amps I am discussing !!  

     

    Likely, its totally out of your realm of experience, listening-wise.   

     

    There is a considerable LISTENING differences, between all the pedestrian made-for-the-consumer amps and world-class builds.

  6. Carmina Burana   I made it through about 20 seconds of the chorus as that is really not my cup of tea. The thing I am looking for would be focused on drums and not having drums as a small part of the overall music.

    percussionist, once by trade.  I have extensive experience with sound from a first person perspective.  I'm not disputing anything you say, just commenting on perspective.  Like I said, it is great when someone has that epiphany of how awesome music can be.

    True and until now I did not know what I was missing. OK where can I find good Timpani music? I want thunderous rolls to feed my S-MWM's with.

  8. Adding to all this. I am finding with the S-MWM my tastes are changing and classical is getting more and more of my time. So many subtleties and powerful sweeping bass and love for what correct playing of stringed instruments like Cellos and Double Bass sounds like. Just so much more than the R&R which it is displacing.

  9. When you consider how much used Klipsch has gone up they are not high. When you consider that used Heresy's are now mostly 5 to 600and up they are not high. people who think things have gotten ( not saying you Tom just people in general) to high were asleep at the wheel and waiting for deals that wont ever be back unless you are super lucky.

    If you want to test those subs with something very accessible, try the E. Power Biggs, The Philadelphia Orchestra, Eugene Ormandy, Camille Saint-Saëns ‎– Saint-Saëns Organ Symphony." In my case, a life changer. PWK played it for me in his listening lab, which is now the museum, about 1972 from a 15ips R2R on an Ampex 350 console deck. By pure chance, I found it among his R2R archive when I was asked to archive the collection to digital. If the descending C major scale at the end doesn't ring your chimes and rearrange your china cabinet I suggest just sticking with classic rock.

    E Power Biggs for best rendition of Toccata in D Minor I have ever heard. The right recording of Vivaldi Cello right behind it. Here is an organ I wish I could find more music for.  This one is going to SWAG and let me tell you it is fabulous. I think I will go out and play it again shortly. Enrico Dindo has a Cello from the early 1700's and the tone is perhaps my favorite of all the Cellos i have heard.

  11. I have a really nice Forte II in Walnut. Excellent pattern and no damage anywhere except for some very small pickouts on the base. You would be hard pressed to find better. I have not done anything to them yet but will shortly begin the upgrade process. As it is $350. + recap  and LMAHL V2 + L-Pad will be $525.00. If you are looking for  a center channel this could be it. Yes of course I can bring it to Hope. If anyone is interested I will get pictures posted.

  12. Kirby and I were talking about MDF the other day. I took him outside to my flatbed trailer and showed him a piece of 3/4" baltic birch under the tongue jack where it has been for months in a very wet period and with freezing and thawing. There it sits stained but otherwise as good as new. No delamination no warping no rotting. You want strength in all ways and good acoustics BB is what I choose to use. Here in Nashville this is what the lumber yards tell me. MDF goes into car boom boxes and BB goes into speaker cabinets. They sell so much BB that even with  the 9.75% tax a 60" x 60" x 25mm sheet costs $48.00 out the door. Music City has spoken and it's preference is BB.

    My musical palette has actually grown quite substantially since the Great Calliope Incident and I may just find myself genuinely enjoying it this time around..

    Mine grew after the S-MWM's and I find myself looking for helicopters, artillery, thunderstorms, double bass, organ music and yes the other day  carillon music. Looking for big deep bells. Trying to find worthwhile tympani and all I get is junk and some what interesting Japanese drums. I did find this amusing video though in one of my searches.

    Really only have some sample sets which I downloaded for a project some years back. Love those things! However, if I remember I'll dig up my old LP "Sublime Harmony," British pressing of vintage music boxes. Mind blowing fidelity! Thad and Carl will love it... Maybe start a whole new tradition. 

    Dave

    I am interested in those types of things. Mind blowing fidelity is what I want.

  15. I am thinking these were just placed in there loose and as brittle as they are that was the end of that. Rigma sold a bunch of 510 horns that were lose in a load to a forum member and when he got home they were all toast. I have some 510's right now and they are dangerously brittle. Popouts around screw holes easy to do and mounting flanges are EASY to crack. You get any of these old horns be forewarned to be very careful.
