![]() ![]() ![]() The wrong tool at the right price is still the wrong tool. I would expect it to sound worse, especially as I'm sure you'll end up doing injudicious things with the graphic, too. Unfortunately, you're adding a bargain bucket graphic to a bargain bucket speaker system. Cheers.Why would you *assume* it's a 12dB "curve", when a minute of googling would find the manual which would inform you that it *is* (or claims to be) a 12dB/Oct Butterworth filter? ![]() I'd love to try the DBX as mentioned but it's out of the boss's budget for now anyhow. ![]() I'm assuming the curve is only 12db but it's gotta help for sure. The Behringer eq has a variable high pass filter knob. Yes i realise it's a Behringer but it is cheap and will help and again the boss dosen't want to spend too much money and i'm trying to do the best I can. After reading the comments i think i'll buy and install a Behringer FBQ3102HD Dual 31 Band Graphic Equalizer and high pass at around 40hz. my channel default eq uses a 18dB/octave hpf at 60hz Personally, i like having subs which go very low and certainly do NOT compromise their lf reproduction capability (within their useable range) via a processor - on occasions which do not require to go very low, i simply deploy another system. so the short answer is that using hpf's (on channels and/or subgroups) can help to get a more 'tight' sound however, you risk loosing the fundamentals and the mix can become rather 'thin' in sound. Your pa system's frequency response and how it 'feels' depends on a multitude of factors such as what speakers are getting used, what you're feeding the pa in terms of frequency content, the positioning of subs within the room/venue, arraying and alignment of subs etc. Has anyone else heard this theory? Is it wrong or is there something in it?it's not really a 'theory'. Rolling off those lower frequencies could potentially clear up and tighten the low end a bit. As a result the sub is trying to play the lower frequencies it can't and the end result is a bit more mud/distortion coming from the sub. The idea is say your sub goes down to 35hz so if you play a song that has information below 35hz the mixer still sends that information to the sub telling to produce that sound but the sub can't. I've heard that rolling off frequencies below 30 to 40 hz (depending on your sub) before the signal goes into the P.A speakers is a good thing as it helps the speaker perform better. ![]()
