noviygera Posted October 17, 2020 Share Posted October 17, 2020 Thanks for the feedback, guys. I am going to look for a pair of these for now. Seems like a good first option to try, without building anything. I'll post in the classifieds. If anyone knows anyone selling these, please send them my way!

codewritinfool Posted October 17, 2020 Share Posted October 17, 2020 On 10/16/2020 at 11:39 AM, ClaudeJ1 said: Yes, it's called a Quarter Pie, since I designed that and the Super MWM. The quarter pies uses roughtly the same corner space as an FH-1 and is flat to 50 Hz. instead of 90. It's only a 90-135 degree single fold but I never used it past about 300-400 Hz. Very easy build.

Dave A Posted October 18, 2020 Author Share Posted October 18, 2020 Thinking about making a set that is van portable where the S-MWM's are not. Oh and they will go deeper. Quote Link to comment Share on other sites More sharing options...
noviygera Posted October 20, 2020 Share Posted October 20, 2020 ClaudeJ1, that Q.Pie looks pretty intriguing to me so I am starting to seriously consider it or a variation of. Questions: What is the horn flare rate/type? Is such a fast opening profile necessary or just for ease of building? I ask because I don't have my mid horns in the corners so the Q.Pies would be pulled out into the room, right underneath the mids, where the FH1 is now (potentially, just visualizing at this point). What driver/horn/crossover type did you use above the Q.Pie? thanks! Quote Link to comment Share on other sites More sharing options...

The length may vary depending on what Claude has to say. I don't want the top end of the horn to be below where I need to crossover. Quote Link to comment Share on other sites More sharing options...
Dave A Posted June 9, 2021 Author Share Posted June 9, 2021 Has anyone built these yet besides me? I sent plans out but have heard nothing back yet. Quote Link to comment Share on other sites More sharing options...
Pete H Posted June 10, 2021 Share Posted June 10, 2021 As soon as I get a construction/building/office built, I will. Just trying to get by until the market settles out so I'm not $50,000 to deep into the build. Currently, trying to work with what I have, doesn't leave room for the sets I already own.

Room is an issue for me as well. I'm tapped out with the relatively small space I have for toys at home. Quote Link to comment Share on other sites More sharing options...
Dave A Posted June 10, 2021 Author Share Posted June 10, 2021 Local best source for 25mm Baltic Birch tells me 60" x 60" not available. 4' x 8' is but has gone up to $118.59 from $76 a year ago. I think I might drift up there and get a pile. Quote Link to comment Share on other sites More sharing options...
The Green Hornet Posted June 11, 2021 Share Posted June 11, 2021 I bought 2 drivers (eminence kappa 15c) for a super MWM build. Felt I could do a decent job after what I learned from the pair of f20 subs that I built. As typical with life, I’m trying to finish a degree and we’re finishing our basement for extra living space. Hoping to do a build this fall/winter. Already running the K402’s on Peavey FH-1’s.. I’m halfway there! Quote Link to comment Share on other sites More sharing options...
Pete H Posted June 11, 2021 Share Posted June 11, 2021 @Dave A I still have 5x5 available here but 18mm, never been able to get the 25 Quote Link to comment Share on other sites More sharing options...

parlophone1 Posted August 9, 2021 Share Posted August 9, 2021 Hi Dave A, is there any chance you could test the Super MWMs with the B&C DCX464 and ME464 in near future? That would be really helpful for those that can not get their hands on K-402s. Quote Link to comment Share on other sites More sharing options...

That would be really helpful for those that can not get their hands on K-402s. Klipsch will sell you complete 402 setups all day long plus they will be the latest version with different phase plugs than the old ones you might find used. At least this was true with the 1132 drivers I have and yes the new phase plugs made a real improvement. The diaphragm will also be new and yes that matters more often then you might think buying used. There is no way the 20 year old 402's typically found used will sound as good as the current new offering, in my experience. YMMV Today if I was building a new S-MWM and was going to use the K-402 I would buy a new set and be done with it. If I were overseas where 402's are stupid expensive because of governmental imposed import fees I would use the B&C offering. Unless you have a commercial account with B&C I don't think buying the DCX and ME will save you any money over the K-402 horn-driver-base set which you can also order all day long from Klipsch. Yes I have a set here to try on the S-MWM's as people keep telling me three ways are supposed to be mo bettah. The 402 has a long history of approval and works with more than one driver. B&C will sell you just horns which is a consideration and a crossover to go with the DCX and ME combo but will not do a three way passive. Klipsch will sell you a crossover for the 402 + Klipsch of your flavor also which will power the complete setup..The 402 set will come with a stand the B&C will not. The ME is smaller so if space is a problem that might be a consideration. The 402 is for 2" drivers or drivers with a 1'4" to 2" adapter. The ME is for 1.4" only. The B&C setup has huge output you will have to step on pretty hard to not overwhelm your bass section. The 402 has output that is a closer match to most bass bins out there. Check out the LF to HF ratio on the 942's Now if this is true in general for all HF vs LF (+ MF too in this case) power consumption ratios look at the DCX specs. The complete Klipsch setup is basically the same money as the complete B&C setup. There is no cheap way to get that big horn sound and you are going to pay in time to build something or time to buy known correctly engineered and built things or maybe get super lucky and find used which is a problem many never solve.. Perhaps the biggest difference between the B&C offering and Klipsch's is B&C will sell you individual components since they are not in the business of selling complete speaker builds. No I did not post this Klipsch screen capture twice. The edit will not allow me to remove it that I can see either so it is what it is.

BeFuddledinMn Posted February 13, 2022 Share Posted February 13, 2022 Great job Dave and thank you and Claude for sharing and educating the forum on the possibilities available. After following your efforts here on the impressive Super MWM design, and Claude’s impressive Quarter Pie design, I’ve noticed that both designs could be cost efficiently built using 5’x5’ Baltic birch sheets for the same 60”x60” x 21” footprint (Super MWM vs Super Quarter Pie). I have been seriously considering building Claude’s Super Quarter Pie, but given the same dimensions and materials, if someone had the room for that 60”x60”x21” footprint, which one should they build? Obviously, the Super MWM goes lower, but are there advantages to both in the same footprint? Quote Link to comment Share on other sites More sharing options...
Dave A Posted September 25, 2022 Author Share Posted September 25, 2022 I was curious to know if anyone else has built one of these yet? Quote Link to comment Share on other sites More sharing options...
