| Sub 20Hz EQ With the 1124SP specification at 20Hz -3db, I presume sub 20Hz EQ is a I've been thinking about an upgrade to a PB12Plus/2 and tuning it for 16Hz because I appear to have significant room gain below 30Hz so a drop in overall SPL for a 16Hz tune would not have a significant effect IMO. However, if my room gain < 20Hz is significant (> 10db) will I run into trouble with EQ on a sub that is producing a response below the BFD's lower operating spec? | Sony KL-50W2 | Denon 3805 + POA-T10 Biamp| Denon 2900 | Pioneer 575-S | B&Ws 604s3/602s3/LCR600s3 in 7.1 | SVS PB12-ISD | BFD | Pinnacle Showcenter |Sky+(250GB) | Cables Scorpion & Mark Grant| Bob - "Malice" was my Quake 2 CTF name | ||||

| Re: Sub 20Hz EQ So what's the lowest frequency filter you can employ on the BFD? -Mike Bentz ~It's all about compromise~ "It's territorial with the soundboard. So you're mixing and some dude comes by spewing opinions and trying to turn knobs. It's akin to going up to an artist and painting over his unfinished masterpiece. You just want to shove your paint brush up his nose and throw the soundboard out the window!" | ||||

| Re: Sub 20Hz EQ So not much good for taming a 16Hz peak which is greater than a 20Hz peak. So, I think my the opening question is still valid! We're stuffed below 20Hz? | Sony KL-50W2 | Denon 3805 + POA-T10 Biamp| Denon 2900 | Pioneer 575-S | B&Ws 604s3/602s3/LCR600s3 in 7.1 | SVS PB12-ISD | BFD | Pinnacle Showcenter |Sky+(250GB) | Cables Scorpion & Mark Grant| Bob - "Malice" was my Quake 2 CTF name | ||||

| Re: Sub 20Hz EQ If you really have a problem, you could always look for a used Rane PE17. It will reach down to 10Hz. | ||||

| Re: Sub 20Hz EQ I don't see how a big rise below 20Hz is a problem, as long as it's room gain and not artificial boosting. The lower you go, the more dB it takes for the signal to be noticeable. So low frequency boosts from room gain should be welcome. I have my sub eq'd flat to 30Hz, where most bass found in music lies, with some small cuts below 30Hz to tame the rise centered around 22Hz. But the peak is still pretty good, which sounds great with movies and video games, and that occasional music track that extends that deep. | ||||
