Default Manger MSW and Eton 11-581/50 HEX Plans

Hello

This is the plans for my future speakers.

The driver will be Manger MSW and Eton 11-581/50 HEX.
The crossover point will be around 150Hz using an Active crossover.

I will use 22mm Finnish plywood for the cabinets and the bracing.

Any comments are welcome.

The Manger is a very interesting breed, although I rarely see it mentioned.


Seems like a great "ultimate" project, because they are almost a grand each right? Which company sells them direct again...that company that sells all those expensive brands like Raven and such.

for those unknown, Manger:

Nice design. Seems like you´re going for a closed design for the bass right ? Tried a reflex myself but the result wasnt as good as i hoped it would be.

Manger + Vifa 8"

Also, active crossover is a excellent choise. Had a very complex filter for my speakers ( wich you can see in the pic above ). Even though it was optimized, it removed ( for lack of a better word ) some of the "life" the mangers do have.

Good luck =)

looks kind of blue to me......
you should have used a bigger driver - small driver and big box generates wrong sound balance...two much "hot air".......

You might want to consider shifting the XO point to 315Hz. That gives you a few benefits:
(a) The MSW gets less of the power, leading to less distortion, and less compression. At the same time, it still carries the human voice.
(b) The phase response in the bass region will improve, provided the bass driver is chosen carefully. You will notice that the MSW has flat phase down to about 300Hz.
(c) The bandwidth of the MSW is slightly reduced, for less IMD.
(d) On a small baffle, the baffle step point is likely to be in the 300Hz region, so it might be simpler to adjust (by lowering the response of the MSW by 0-3dB, depending on listening position).
(e) Smaller capacitors in the crossover for the same resistor size, allowing you to either save money off the caps, or to use smaller resistors for lower noise.

I'm sure there are others I've missed, just as I'm sure someone will be kind enough to point out some drawbacks.

How about using the Seas Excel 8" magnesium woofers with the MSW? Those have impressive distortion figures, and rather excellent detail level. Not sure about the phase graphs, but I think they should be a good match.

i agree too.
i had some extended listening sesion over 2 days with the 109 and although the sites mention the cut off for the 109 begining at 140hz i was told that the roll off actually begins at 300Hz (1st order) and apparently there is also a notch fitler at 380hz. Maybe if you email Ms. Manger she will be able to advise yuo better.
