Exciters used for speakers

Thinking of  my ST70 build in this thread https://dynacotubeaudio.forumotion.com/t3803-started-down-the-road
I know I am going to run into a problem on speakers in the living room where we have the tv.  Wife does not like "big
ugly box's) in her living room.(her description)   So......I ran across this youtube video and I think it might be an answer to my problem plus
solve the money for speakers that do not sound like something that fell off the back of a truck that some guy will make you a great
deal on.

The amp will get the majority of use while watching movies on the TV.  

Skip to the 14 minute mark for the demo of playing music.  

Wondering if anyone has ever tried this. To me, it sounds pretty good considering it came from youtube.


Forgot the youtube link
OOps  sorry ViperZ  here is the link.   https://www.youtube.com/watch?v=zdkyGDqU7xA

Sorry, where is the link to youtube video?

This approach has been around for a long time. I remember BES/Bertagni selling a speaker built this way with an expanded polystyrene (i.e. Styrofoam) panel back in the early 70s. At the NorCal audio show last year someone was demo'ing canvas "artwork" playing music using this principal.

Why not pick up a pair of used Magneplanar MMG for ~$300 and see what happens? They are not the ideal load for your Stereo 70 but will be pleasant with acoustic music and vocals. They are big, but not boxes.

A pair of Quad 11 or 12 or S-1 or S2 two-ways on stands will produce big sound from a small speaker. My bird's eye maple 11L2 are stunning to look at and are voiced like the Quad ESL (a good thing). Again, not a perfect match for the Stereo 70 (is anything?).

J beede, I will check out the Magneplanar MMG in your post.  

This same guy did a little more tinkering and for my 70 year old
ears even with youtube in the middle I think his setup sounded
pretty good.  

If nothing else works for me (ie, wife approved ) depending on
the way I shape, paint them this may get her approval.  If I go in this direction
I think I could make a set that would more or less fade into each panel the speaker(s)
would be mounted to in the living room, If not they will live in my office where I do my hobbies.  


Like I have said any speaker would have to get the approval of the wife.
So, nothing is set in stone at this point.  If things do not work out for the amp

Was just looking at a few of these, I think I may be able to talk my wife into a set. Will have to find someplace that has them in a show room.

Thanks for posting that interesting video.

What about small bookshelf speakers and a sub?

If you’re feeling crafty you could build a pair of these...

They can be painted any color and wall mounted.

I've got a pair of '80ish Gecko flat panels here that sound right nice. Only 14", so not much in the way of bass, but I just use them to augment the rear channels on my quad, so not a problem. Mids and treble are excellent.



One other advantage with the flat radiators is sound field. You can put these thing side by side and still get stereo walking back and forth in front of them. Kinda kewl, that.

I keep a pair of Magnepan (Maggie) IIIas with the outboard crossover. At 6' x 2' x 1.5", they are not exactly subtle in the room. At the same time, they have a very small footprint and fill a very large room (17' x 24' x 10') with clear sound.

Beware that they are power-pigs, and in that room, every bit capacity from my Citation 16 is required for full sound. I am driving the 16 with a Revox A720, quite a combination!
