Subsonic Filter turned off question

[eenyuheye8o8 10+ year member]

Apparently while my friend was tuning my amp he was telling me I should leave the subsonic filter turned off? Basically 15Hz I think that's what my amp lowest setting is. I'm running a CT-SOUNDS 7000. On 2 15 Zv3s with NS Soft parts. Was wondering if that was a good thing or not. I had it set around 25 hertz than he turned it all the way down.

I run mine a half octave below box tuning. I wouldn't leave it off unless it's a sealed box.

What is your box tuned to? no it should not be that low, you can see mechanical damage if the woofers unload trying to play below well below tuning frequency

My box is tuned around 38 hertz and yah I tried to speak up but he kept making fun and saying like It should be turned off if your trying to run SPL but if I remember correctly spl is higher tone notes not lows.

Tell your friend to stop being an ass and do research before giving false advice

Ask him if he will reimburse you if you tear up your subs...?? Tell him to man up if thinks he is correct on this issue!!! Lol

Set it to around 28- 30

Thanks guys for the input I knew I was right.

30ish would be about right.

But in the guy's defense -- setting it at 15 would only come into play if you're trying to blast something way below 38.

If you didn't want to run a SSF or ever run an amp that doesn't have one: You can also easily tweak the EQ on a higher end HU that has a good band-width of EQ adjustments to have a similar effect //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
