Model 19's in Russia

Hmm, 110 lbs might be enough for a M19. No clue what 'obertonal' might be unless it refers to 'overtones'. Regardless, mass loading speakers basically 'squashes' [damps] cab vibrations, making them acoustically more efficient and considering how 'lossy' the M19's construction is it will probably audibly 'tighten' them up. It's most audible with the now popular tall, skinny [ML]TLs for small, medium size drivers or stand mounted 'monkey coffins' and I found no benefit to already really heavy, rigid cabs.

I've done, recommended this tweak ever since I built my first tower/column/[ML]TL back in the '60s when I heard a major difference after placing some heavy potted plants on top to do some damping experiments with drooping foliage, which is very WAF compliant IME, but AFAIK nobody on-line gave any credence to it until a pro designer out of Texas did a quick test by pinning a ~ 2 ft tall stack of vinyl LPs with a dumbbell weight to the top of one of his creations.

"oberton' does seem to equal the word "overtone" in parts of Europe.

Yes, German: dict.cc dictionary :: Oberton :: German-English translation

Also a line of drivers: Strassacker: Speaker Building, Components

Oberton speakers aren't bad. I strongly suspect some connection with BMS, just not sure what it is.

I found the quote below at the Audiogon forum and then read Cradeldorf's and Greg's posts here. I'd never heard of this concept--makes sense that putting a heavy weight on top of a speaker will help minimize cabinet vibrations.....

"05-03-08: Psacanli
Not too argue.
The speaker pistons create vibration.
Vibration is not helpful for good sound.
Mass will absorb vibration.
A leather bag of lead shot and sand will work well.
As heavy as structures allow;in this case there's
no such thing as "too much of a good thing"."

One more reason that stacking speakers has helped the sound of my system. Who knew that putting the Santana II's on top of my Model 19's would be an upgrade even if I disconnect the speaker wires from the Santana II's!

Imagine how good the Santana II's would sound with the Nineteens on top of them. :D

I just noticed the 2nd pic is a series 1 Santana II(old style steel frame woofer?) and the 1st pic that pair is series 2. How many do you have?

Too funny! I've got two pair of Model 19's and two pair of Santana II's. After I bought my first pair of Model 19's for my basement rec-room/mancave, I liked them so much I bought a second pair of 19's for my basement recording studio (the big room). I found my first pair of Santana II's locally and practically stole them--when I stacked them on top of the Model 19's and played them simultaneously there was a noticeable improvement in overall sound--especially bass and mids. So, for over a year I searched for a second pair of Santana II's and when I found this mint pair (with the newer style woofer frame) I bought them and put them on top of my other pair of 19's. I still have my Model 14's in the living room--perfect size for that room and with the wide dispersion of the Mantarays they really sound great in every seat in that room--those 14's rival the 19's in many ways.......
