It’s simple to understand and it was understood in the 80s buy two prominent speaker builders at the time, Carver, and VMPS.
They both understood that cabinet resonance transferred to a common medium will induces a third passive driver. There is no way to USE the signal without introducing a serious timing issue between the air being pushed from the drivers, vs the arrival time of the floor, walls. and ceiling. The floor is quicker..
Smearing happens by funneling all the different frequencies into ONE common medium, (via spikes)
What I learned from Brian Cheney and Bob Carver is the term BASS cohesion. The second is BASS propagation
The signals that were being transferred to the floor are now stopped.
They decouple, easy fix. BUT we don't raise it to much because of bass LOSS, WHY? Bass uses boundaries to GROW or propagate. YOU will hear the bass from that speaker go DOWN in volume, ACTUAL volume..
Cabinets do not move if they are made for one thing BASS.
The monitors can’t move because they weigh 425 lbs each and the BASS is in a different cabinet..
We help a CABINET dissipate the vibration a few ways. No bass in the monitor cabinet and narrow the baffle face to reduce the collection point for second hand bass.
In the bass cabinets use sound coat to reduce resonance issues THICH walls of MDF and bracing to reduce any panel lengths over 8". The cabinet is MADE for bass, not every frequency on the planet...
Pods, Springs, Air ride or a good sand pit the SUB cabinets. (I'm using OB servos by GR)
Pods, Springs and or air ride the Mid Bass Cabinets. My MB LS Columns
Pods, Springs and or air ride the Monitor cabinets. VMPS Elixirs..
Dear Mr. Richard Vandersteen, Spikes?
With great respect and regard
