    While measuring pink noise with REW I’ve always noticed that my measurement never quite stops moving, nor does it really settle at all. Is this normal? From what i’ve seen in how to videos it usually moves for a bit and then settles into an average. Mine jumps up and down the whole time making...

    Alright so here’s a shot of the near field frequency response of my driver side midbass -electronically crossed at 70 and 300 LR4 with no EQ- next to a flat target curve with matching crossovers. now here’s a look at that same drivers response from listening position -again no EQ just...

    Here is my frequency response in REW (note that the sub is off. These are separate L-R readings. The tweeters are on an active crossover @ 3.5kHz) See how the 100-300Hz range for the midrange speakers is much lower than the 400Hz-3.5kHz range? So that makes me wonder, when EQing, do I boost...

    Here is an example of my front speakers frequency response (Sub off. tweeters and mids are on active crossover @ 3.5 kHz). As you can see, the 100-300Hz range of my midrange speakers is much lower than the 400Hz-3.5kHz range. So do I EQ the 400Hz-3.5kHz range DOWN to this level, with the...
  5. System Design: Help Me Choose Equipment For My Car
    I have noticed many amps have their freq response bandwidth of 20hz to 20k hz or thereabouts, within a certain db. I am looking for lower range for sub bass response. For example, today I found an Orion HCCA 250 "digital reference" with a 6hz low end of the bandwidth for frequency response...

    Alright guys! Quick rundown.. Currently, I am running the oh-so-loved Acoustic Elegance IB12s in an infinite baffle. Feeding them roughly 200w each. Given the music I listen to/ music I make (part of Bass Mekanik records), the low-end rolloff just does not work for me (steep drop at 29hz). If...

    Hello fellow forum members! Long-time lurker, first-time post'r, love the site. :) I haven't exactly DIY'd my way to where I am now, but I've been to two different car audio shops and cycled through more components and speakers than I care to admit. I'm hoping I can get some expert advice on...
