Sub Equalization With High Pass Filter

**Ryans_Room** · **05-11-09, 01:49 PM**

I want a BFD to equalize my subs but I also want a ssf (15Hz). I would like to get one unit that can do both for me. Any suggestions?

The Symetrix 551 has five filters and a ssf down to 6 Hz. The ssf is only 12 db/octave, though...

I cannot seem to find the 551 on the Symetrix home page, a direct link would surely help.

It's discontinued, so you'll have to eBay it.

I suggest you look for a used SMS-1. It gives you a lot more choices for a subsonic filter than 12db.

Plus it has an easy to use menu. You can find them used for around 300.

Though I wonder if it's necessary to ssf that low.
