Driver dB vs. low frequency extension

chuck55 · 24th March 2010, 02:38 AM

A while back, someone ran a really great driver design program that showed how loud a driver could play with various low frequency extensions. For example a Tang-Band W3-817s could play up to 90dB if the driver did not go below 200hz, or 60 dB if the driver was used down to 80hz.

Right now I have a Seas W12CY003 that I run full range with no x-over.

THE ART OF SOUND PERFECTION BY SEAS - E0044-08S W12CY003

I am trying to figure how low can the bass go. I listen at 70-75dB max which is 75-80dB 1 meter from the driver. Can some one calculate how deep I can eq. the bass? I am ordering a Behringer Ultracurve pro DEQ2496 tomorrow for this purpose.
Here is one review of it:
