The Entropic Speaker Isolator was designed specifically for use with speaker stands in mind. It features the same 3D-2 technology as other Les Davis Audio products but is built to support spiked speaker stands. They can also be used directly under bookshelf speakers.

The results of placing them under Hi-Fi components are instantly noticed an increase in bass, depth, and soundstage. 

I recommend prioritising them in the following order. 

Pre-amplifier / Integrated amplifier

Music streamer 

Cd Player 

Power Amplifier 

The Entropic speaker isolator is sold individually (single unit).

Key Features
- Single speaker isolator
- Based on 3D-2 Technology In development since 2005
- Multi-layered construction

The 3D-2 Technology.

These deceptively simple looking devices are actually the result of years of research and development into a modern technology known as constrained layer damping (CLD) to effectively suppress unwanted vibrations. While this technology is used in a number of applications, including the aerospace and aviation industries, Les Davis Audio has developed his own proprietary CLD material and has tested it over an extended period of time. The results are evident in Les Davis Audio's 3D Constrained Layer Damping devices.


3D products are simple to use. While the Entropic speaker isolators are specifically designed for use with speaker stands, generally Les Davis Audio 3D-2 products can be placed under all types of audio components to reduce unwanted vibrations, specifically the "3D⁽²⁾" isolation feet. They can be placed under turntables, digital sources, amplifiers and pre-amps, power supplies, motors, underneath loudspeakers and power boards - see the "Vibrare Fermata", made specifically for use with power boards, or the "33⅓D" record mat specifically designed to be used as a vibration controlling turntable slip mat.


In each case, 3D makes a significant sonic difference in the overall sound, such as reduced noise floor and fuller sounding music with more impact. This isn't a subtle effect - you will hear a difference when you use 3D in your audio system!
