SPL versus fan noise

Filed under: Uncategorized — bassment @ 9:58 am

One thing we are trying to balance is SPL output vs noise … more SPL is available if there the manifold is shallow, however, this comes at the expense of more fan noise. The deeper the fan sits back in the manifold, the more high frequency fan noise is captured by the baffle insulation, but then SPL starts to be impacted.

So, this is what we are working on today as we build the manifold. Also we are designing the mounts for the TRW fan motor drivers… we will hang them upside down from the garage floor parallam joists. This will isolate the fan motors and vibration from the media room completely. Good solution.

More pics coming later today.
