have tried Maggie wings for last 2 days are they siimply are amazing at improving the bass.
Made from 1/2" baltic birch plywood they extend the baffle of the 2.6s sideways.
The archives here are a bit confusing in that some have made wings and have them positioned at 90 degrees to the speaker which doesn't make sense to me as the theory is to block some of the backwave from cancelling bass coming from front plane of speaker.
Anyway this is a very cheap tweak with very apparent results and no downsides because you can remove the wings easily after listening and put them away.
The ones I made are 12" wide at the bottom
50" tall and cut into a triangle.
I will experiment with larger ones later but am VERY happy with the bass in my room from this addition.
Follow Ups:
the tweeters on the outside and the bass on the inside ? With what results ?
Are the wings positioned on both sides of the speakers, or only one? If only one side, which side is recommended - inner, extending toward the other speaker, or outwardly. If only on one side, why? As understood, they are in the shape of a right triangle. - Is this correct?I'm a little confused as to what they actually look like and would appreciate clarification.
Hey Jim,
My ribbon tweeters are on the inside of the speakers.
The wings (one per speaker ) are on the outside of the speaker.
Yes they are in shape of triangle:50" high
12" wide at the bottom edge
tapering to a point at the topIf still not clear then ask me more questions
...does wing elevation help? Parts of me think that blocking the soundwaves near the floor is what helps. OTOH, given a 50" wing, would elevation above the XO to the driver region help by manipulating the non-reflected dipolar pattern.IIRC, the 90° (rearward) wing doubles as making stands more rigid like support/damper for a flying-buttress. The 0° (sideways baffle-extension) wing works best with internal tweeters to block reflected waves with the assistance of a nearby sidewall (to help complete the blockade). Otherwise, I hear that 45° wings rock.

Tried them yesterday above the XO's at the bottom of the speaker and the bass is slightly tighter but some of the lower midrange body is lost.
Prefer location sitting on floor.
Bass-side only wings, correct?

Hi Mart,
the wings are sitting on the floor beside the speakers while the speaker is elevated on the MYE stands and spikes.
Haven't tried them up higher where the bottom of the bass driver actually starts.Will try that when I have some time.
Hi Scott,You said the "wings" are 50" high ... is that how high your 2.6s are? If not - and they're higher - why did you only make them 50" high?
And what's the theory behind the triangular approach? Is it a kind of compromise between boosting bass near the floor and not impacting mids higher up?
Regards,
The motivation for the shape i made was to fit inside the Mye stand strut on the bass side of the back of the speaker.
after experimenting I just leaned the wing on the back edge of the speaker so that it extends out sideways.Does snot affect the mids or the highs or the amount of air around instruments but does great things for the quantity and clarity of bass.I have no desire to get a sub with the bass I now get so to those who are thinking of a sdub here is my suggestion
Cardas placement + Mye stands + wings = great bass
Know I'd like to see how they came out.
just 2 pieces of plywood cut into triangle shapes with dimensions as mentioned.
I don't know how to post a pic here.

The key is to make the baffle size as large as possible. Whether this is to the side or 90 degrees does not make much difference at bass frequencies, as the bass waves warp around and cancel the wave on the other side- the lower the frequency the more they warp. Baffle extensions should actually avoid blocking the reflected wave off the back wall, as this will cause the speakers to loose the dipole "airyness" (kind of like placing something bulky between the speakers). Folding the baffle back will make it less visually intrusive (and add stability) while providing the same effective baffle area. Look up dipole subwoofers (linkiwitz, etc.) for more open baffle designs. Another benefit of having the wings go to the back is the reflected high frequency sound from the back wall will be less impeded.
"The key is to make the baffle size as large as possible" ... surely there must be some science here? :-))If my IIIAs are 5 1/2 ft out from the front wall then I suspect running baffles right back to the wall would not, in fact, give a goos sound. Whereas, say, 12" baffles could well be a reasonable extension ... but maybe 18" is better??
And what do you think of Scott's triangular idea? Again, that kinda has a good feel about it but is there any scientific basis to back up the idea?
Regards,
Well, in terms of the "large as possible" comment, that was a bit of an exaggeration- you wouldn't want it to take up the whole room.In terms of the triangle concept- I think there is a lot of merit to having the baffle narrower at the top than the bottom. At the bottom, the floor would be used as a boundary to increase the effective baffle area and improve bass response. In addition, the narrower baffle extensions at the top would interfere less with the high frequency dispersion and reflected sound at ear level (especially with line sources and their very controlled high frequency dispersion). This lack of high frequency boundary interference would preserve the "open" and "airy" sound.
I was thinking had a few thoughts and ideas:
• Curve around to the back from the flat front of the panel (limit any diffraction from sharp edges on the front and early reflections on the back), with the top being narrow and the bottom wider.
• Integrated into the frame/baffle structure rather than just tacked on.
• Asymmetrical profiles to match the asymmetry of the driver placement
Thanks ... good thinking, Charley Brown! :-))Regards,
Andy
Haven't experimented with baffle size but did experiment with positioning and wings to sides as opposed to fins running back from the speaker proved to be much better results for me.
I know you are having Orion desire so try this cheap tweak for your bass!!
Yes, I posted that I had listened to some Orions and was mightily impressed by their bass!! :-))However, if I ever sell my Maggies and go down the cone dipole path, I will build all-active NaOs (same twin Peerless bass drivers & XO point) rather than Orions as I think a 2,500Hz XO between mid/treble is preferable to a 1,500Hz XO point.
I'm not sure my wife is tolerant enough to let me try out your wing tweak, but I'll try and give it a go, sometime!! :-))
