The Half Plate is half the size of the Universal Side Plate and is designed to fit ‘L’ arm style hardware such as Gibraltar, DW, Ludwig, Tama, etc. It will adapt to any ‘L’ arm mounts that use the standard 2 vertical bolts with the dimensions of the 2 bolts at 2” to 2.5” apart. |

 Acoustical Suspension Drumming is all about sound. Curiously in the evolution of the drums, drum makers until very recently gave very little attention to the detrimental effect that mounting hardware had on a drums resonance, After The RIMS® system was introduced, many major drum manufacturers at first were slow to even consider that "suspension" was anything more than another drum "gadget". RIMS® remained a secret of primarily LA studio drummers. When the sound got out, imitators invariably ignored or violated critical principles of acoustical suspension, offering little if any, improvement in the sound of the drums over their existing through the shell mounting systems. Suspension of a drum merely means that the drum is physically supported. Acoustical Suspension Mounting mounts the drum in a manner which allows the drum to produce the fullest sound possible from that particular drum. Many drum manufacturers offer suspension systems, but only RIMS® & RIMS® Alloy® provide all of the necessary elements for true acoustical suspension

Adjustability: The Tweak Factor
The alignment of the RIMS® band has always been a critical factor in achieving true resonance isolation. "Knock-off" systems may have a similar cosmetic appearance to RIMS®, but only the patented RIMS® & RIMS® Alloy® Systems have all of the functional elements necessary to achieve actual "resonance isolation". You can hear the difference!

Alloy: The Next Step
The original steel band RIMS® system offered a major enhancement of drum resonance projection by isolating the drum from its mounting hardware. Steel has a tendency to vibrate at it's own competing frequency which can dampen the drum's resonance, especially when the drum is tilted. The RIMS® Alloy® Series addresses this anomaly by using a special extruded aluminum alloy. Aluminum unlike steel, does not exhibit resonance conductivity away from the drum or promote sympathetic "cross talk" resonance. The alloy's characteristics provide greater isolation hence improved resonance projection of the drum when compared to the original RIMS®

Resonance Isolation When a drum is struck,it causes the heads and shell to vibrate creating a form of raw energy wave with a specific set of characteristics. Like other forms of energy, i.e. electricity, the resonant energy wave will disburse through anything it touches, reducing volume and altering the tonal quality of the drum. A practical demonstration: Remove a small tom-tom from your kit and hold it in your fingers by the counter hoop. Strike the drum with a stick and listen to the fullness of the tone while the drum is suspended in your hand. Then reattach the drum to your kit or strike a similar drum that is post or static shell mounted to your kit. The difference in tone and volume is caused by the acoustical equivalent of a short circuit in the drum attached to the kit. The first RIMS® (Resonance Isolation Mounting System) was created by GPI in 1979 as a studio solution for resonance "choke-out" and "cross talk" vibration created by drum mounting hardware transferring the resonance of the impacted drum to the shells, heads and hardware of other attached pieces. RIMS® was the first and today remains as the only true "acoustical suspension" system available for the professional drummer .
