newls1 Posted December 21, 2008 Report Share Posted December 21, 2008 I have a MD3D amp, and I've always left the Hz setting to around 80Hz (setting goes from 40Hz-240Hz) as I thought 80Hz was about right. Lately either im getting used to what I have, but it just didnt "FEEL RIGHT" as far as bass is concerned. I moved the Hz setting to around 100Hz, and that really made a nice difference. Is it OK to have this @ 100Hz, and or what do you recommend? Thanks Quote I love my staffie So anti FACEBOOK it isn't even funny Link to comment Share on other sites More sharing options...
AI James Posted December 21, 2008 Report Share Posted December 21, 2008 its ok but imo thats midbass ``freq. my subs never play 100hz EVER. its time for you to upgraade front stage if its lacking Quote Link to comment Share on other sites More sharing options...

Using an 18dB slope at 80hz LPF (what the majority of people use) considering cone area and power difference it's likely the subs are still the dominant source of sound at 100hz.

I dont understand what your asking? There are very few options on the MD3D amp's....

raytard Posted December 22, 2008 Report Share Posted December 22, 2008 mine is at like 90ish 100 is high for 18's, 80 or 85 seems safer, and while it may sound better, youre going to be putting hundreds of watts through them with fairly little movement, and those subs are designed to cool themselves off pounding away at 40hz, not fluttering at 100.

AI James Posted December 22, 2008 Report Share Posted December 22, 2008 mines at 70-75 using a dqx-s when i have it installed midbass blends in at about the same numbers Quote Link to comment Share on other sites More sharing options...
Fish Chris Posted December 22, 2008 Report Share Posted December 22, 2008 I agree with James. That's why I have to have mid-bass drivers in my upcoming system. 100hz or higher is too high for subs to sound great.... and 70hz is too low without mid-bass to fill in the gap. In fact, if my mid-bass drivers perform as well as I'm hoping, I might even cross my subs over at 60 hz down. Then grab 60 to 300 hz or so with the mid-bass drivers, and 300hz and up with my mid/ high components. Peace, Fish Quote Link to comment Share on other sites More sharing options...

Peace, Fish thats sounds like a good plan man. i have never ran a mid bass driver myself. but, after hacing this 15 for a few month i see the importance and over all sq i am lacking. so i will deff. be adding som very soon.
