Replacing sound proofing in cabniets

Hi Sean,

I generally agree with your post. The reality for a designer of a commercial speaker is that they are always walking a tightrope and doing a balancing act. No matter what the price point of a speaker (even the relatively new breed of extreme megabuck speakers) the designer is constrained by cost of parts, manufacturing and marketing versus the quality and performance of the parts available versus the size of the speaker system and its practicality for shipping and placement within the customer's home.

In the speakers that I have designed for commercial sale, maintaining a moderate size was a siginificant factor and an aperiodic loading chamber was employed to provide the target response for the system.

In my personal speaker system I do use a low Q sealed system for the dynamic woofer section.

Best,

Barry

Sean and Bright star...have you ever heard of anyone using the black undercoating in a spray can that can be bought at any of the larger auto parts stores for damping? I really think that would work very well..whatcha think?

Hi Tunes4me,

The spray may be useful to damp the interior of a component's chassis. It would mainly damp gross ringing of the chassis but it can't absorb a large amount of vibration or even damp ringing as effectively as some other applied coatings or materials. The damping spray would be considered only PART of an overall scheme to eliminate vibration.

I have used it in a few cabinets. In the grander scheme of things, it is just about useless on a well designed cabinet. Other than to help seal any seams / cracks and help keep the cabinet "air-tight" if sealed, the benefits / results are far out-weighed via other simpler and less messy methods. Sean

Hi Tunes4me,

Bright Star speakers did use multiple layers of compliant ceramic and a special damping compound that I developed that were quite effective when applied correctly to cabinet panels, driver baskets and crossover components.
