Regards, Emile No problem. It was late and I was cranky. It will be a good performer with a small footprint. The Neo driver is more expensive, but it will give you less weght. Perfomance will be almost identical to the "mud magnet" one. 1 Quote Link to comment Share on other sites More sharing options...

In a small room, there won't be more than a 6 db loss to the listening position, depending on room treatments, and how much stuffing in the cabinet.

Emile Posted February 13, 2019 Author Share Posted February 13, 2019 OK; bit lost now @ClaudeJ1's "double" Super Heresy's (haha; obviously) seems to be the best way to go. But, hope I can ask some stupid questions just "to learn," as I am not up to the level of you guys First; still looking at the CF3's, v3 ... is this a terrible solution as these just won't get me the output of "pro" woofers??? Second; have this set of Forte I's ... how about just putting "pro woofers" in those (and of course forgetting about the horns since I've got the 510's)??? Third; since this system is in a "small" room, how about just a set of single Super Heresy's (again bypassing the horns)??? It's probably obvious from the above "simple" solutions that I am trying to avoid building new boxes Many, many thanks!

Cheers, Emile Looks to me like you'll do most anything to get out of making saw dust at the correct dimensions, rather than doing it right, won't you?? I'm not picking on you, just telling it like it is...........$$ and WORK. That's why it's called DIY, you gotta do it all yourself. Cut 12 pieces of wood, cut 2 rectangles and 8 holes (2 for the woofers and 2 for the same ports used in the Super Heresy). Use screws and glue as required. Figure out the stain or no stain or glossy vs. satin finish. Done. Then invite friends over for the demo of world class 1st class speakers after you get the networks built. No short cuts!! 2 Quote Link to comment Share on other sites More sharing options...

Cheers, Emile How about finding something similar to this pair of JBL's? find a model known for their good qualities for your 510's. https://www.ebay.com/itm/Pair-2-JBL-SR4731X-F-SR-X-Dual-12-three-way-Loud-Speaker/163521247053?hash=item2612a0374d:g:UtAAAOSws~dcVSNt:rk:12:pf:0 1 Quote Link to comment Share on other sites More sharing options...

In my opinion CF-3's with its dual 10's won't get you that chest thump I think you are looking for. I have the CF-4 w/dual 12's and even though you might think they would have a lot of bass, they really don't. What you get is some really clean articulate mid-bass. In my 3.1 setup a 15" sealed sub adds that chest thump, which doesn't come through the subs directly, but through the speakers. +++ Did you see my suggestion earlier in this thread for the DIYsoundgroup mid-bass modules? I thought you might have missed it. Trust me on this. Quote Link to comment Share on other sites More sharing options...

Thank you SIR ... OK; scratch the CF3's off my list Don't need "chest-thumping," but my Forte's are just anemic (OK; when I compare them to pro speakers), Still hoping to find a yes/no answer on replacing the woofers with pro's in my Forte's ... but hate to spend $200 just to "try" it Yes; did look at DIYsound. Very interesting, but "stuck" with their woofer ... and the 12" box seems a bit small Jeez ... continuing ... but guess these are good problems to have Cheers, Emile Quote Link to comment Share on other sites More sharing options...

I thought you were looking for a strong mid-bass module because you had some horns to put on top. The flat pack box is close to the dimensions you had listed, and yours were for 2 woofers. You can get the flat pack without the front baffle and woofer. If you have the tools you could cut your own front baffle. Those flat packs are CNC cut and are super well designed, the fit and finish is incredible. All you need is glue and tape to put it together. I've built three of the 3 cuft boxes for the 15" sealed subs. Maybe you have woodworking skills and tools, but for a guy like me those flat packs are worth the price of admission. 1 Quote Link to comment Share on other sites More sharing options...

Was looking at the Eminence Pro series. Any pro speakers I heard (and owned) are just so much more powerful (and to me more defined) than "home" speakers. DIYsound 12" box is 26x14.5x15 ... quite a bit smaller then the Forte's at 36x15.5x12 (about 20% larger). That's why I thought I might be able to use the Forte box just as a bass bin with a better pro woofer. BTW; got a 15" subwoofer kit from PE based on your recommendations. Pretty sure these are the same. Awesome. Easy assembly ... Of course had to veneer it for the WAF Haha; not looking forward to building from scratch ... only as a last resort (Getting older ...no fun hauling 4x8ft panels.)

Once the saw is set up, they just get ripped for you at the same dimension.

The power handling is 10-1000 watts. Custom made Eminence high end 12" woofer. Easy to power 8 ohm load and 93db 1w/1m sensitivity. Will handle up to 1000 watts and play over 120db. 2 hours ago, Emile said: BTW; got a 15" subwoofer kit from PE based on your recommendations. Pretty sure these are the same. No, not the same. DIYsoundgroup has the 3 cuft 15" and 4 cuft 18" subs but these are MBM mid-bass-modules. The custom 12" woofer used in the Maximus-12 is capable of very strong midbass output. Some people asked if a Midbass Module kit could be made using it, so here it is. This is basically lower section of the Maximus-12. There is now a flat pack designed specifically for this kit and that is the recommended size along with a single 4" port. I'm not trying to talk you in or out of anything. I just figured I'd pass on some information you might not have seen. 1 Quote Link to comment Share on other sites More sharing options...
ClaudeJ1 Posted February 14, 2019 Share Posted February 14, 2019 While it's good to do research, at some a point a decision must be made. Otherwise one can say it's the "paralysis of analysis" in action. 2 Quote Link to comment Share on other sites More sharing options...

Emile Posted February 14, 2019 Author Share Posted February 14, 2019 Update Yes; dual 12's or even a single 15" will be THE way to go. But, having a knee replacement in 3-4 weeks so won''t be able to do much lifting/fabricating for a couple of months Had some GREAT PM discussions with @wvu80 and @moray james (THANK YOU guys) and first going to try a pair of Pro woofers (Eminence Delta 12LFA) in my Forte cabinets. Moray thinks it might get me close to Cornwall's. Hey; for $150 it's worth a try OK; will probably build another box in 3 months ... stay tuned. Many thanks for everyone's input!

MenloBob Posted February 20, 2019 Share Posted February 20, 2019 Any thoughts about using one pair of Super Heresys as the mid bass cabs underneath a top cab with 510/K691s? I have a pair of mid eighties H2s in storage I could use the cabinets from. Would probably build fresh motorboards and backs so I could put the heresys back to stock in the future. Which drivers would work best, the Eminence KappaLite neos? I have everything I need for active crossovers and measurement with REW. The rationale is I'm extremely space constrained so horn loaded bass cabs will have to wait ten years until I retire and move out of silicon valley, at which point I'll probably get a pair of Jubes. I have the H2s just sitting in storage so might as well use them. I'll probably start with 2 channel stereo and possibly add a sub depending on how the room coupling measures out. Is this a crazy idea? 1 Quote Link to comment Share on other sites More sharing options...

Hi Bob, Welcome to the forum Certainly not a crazy idea Probably would work ... are you thinking of building a set? However, slowly starting to think trying to add "non-pro" Klipsch speakers is just going to be a mismatch with the 510/691 horns OK; the Eminence Pro woofers just arrived Will hook them up and let you know the results - withing a couple of days.

It's much easier to get the balance right with full active crossovers and DSP filtering. 1 Quote Link to comment Share on other sites More sharing options...
