Unless you're using a measurement microphone, you're not really going to get useful results...

i dont know im using the one that came with my denon :laugh:

if that one isnt the one im suppose to use any recomendations i do notice that im supposevely doing 98 dbs at 2 hertz which i highly doubt but the rest of the bass curve seems about right (above 30 hertz using my radio shack meter)

Behringer makes a nice mic...ECM-8000 is the model number I think. You'd also need a preamp to get it to sound card level.

ok after talking to someone that know about the software im using we figured out i had some settings wrong and that i can use the mic i have for some ruff estimates but its best to get a mic like jim suggested



my laptops speakers at 2 inches away lol

What software are you using for measurement? And yes, I do think you need a better mic.

I think that Brokeinger mic is the only thing that they still build that isn't crap....


Sorry, all you Brokeinger lovers, but it is the hard hard truth... ;) :fyi:

The DCX2496 ain't to bad, I haven't had any problems with it yet.

You find me something else that I can run 3-way active with that is mildly reasonably priced... But I do know that the behringer starts playing funny stuff with the levels and curves when the line levels get to low...

I like Ashly but, you are right that would be a bit more expensive....

An Electrical Engineer's perspective on the DCX (well, part of it, no, I'm not going to say who this person is or who they work for either)

"The DCX is an ok piece IMO. Lots of capbilities and decent hardware. The the filter algorithms aren't that great; at low levels the curve stop following the rolloff characteristics you choose. I think it starts deforming the curve about -50dBFS."

thanks jim for the advice picked up a mic and a preamp today in the morning been playing with the it all morning and im getting close to a flat curve but i need an amp and an eq with more bands to be able to adjust everything just right

it does sound way better so far almost like i have new speakers lol

what ***** is i found out my response below 25 hertz dips bad so its true even with the built in subs in the def techs you still need a sub :(

anyone want to loan me 5-6 grand for a new sub,amp,eq? lol

actually i want the def tech with the 3-14" subs ive read reviews that it plays all the way down to 11 hertz dunno what the drop off is though

and then 2 grand for the rotel 1095 which i want bad and i dunno im guessing a good eq is another 1500

This is what impressed me most about the Axiom sub. I was originaly going with the EP 350 but after reading more about it and evaluating online reviews I dished out the extra 600 smacks for the EP500. Granted that my space is no where near what most of the reviews and especialy the below graph replicates I am trully eager to try it out. Few more days...:yumyum:

The sub:

The sub is able to dip in the teens and still be smooth.

Took my first measurements this morning. I'm pretty happy with what I am getting. This is using a RadioShack condenser boundry mic, has fairly flat response from 20hz-18khz.

*I do not have an SPL meter handy so the vertical scale is not calibrated..... but it still shows the response properly*

Sorry it didn't look more like Jims prediction :crap:

is your might c weighted? i think you have to unclick that on the menu of the software the settings cause i doubt your just as loud at 2 hertz then you are at 50 hertz lol

and zoom in your way zoomed out so the response looks flater lol

right now from 200hertz to 10k i am at +3-3, it drops off pretty sharp around 14k and spikes around 125 (subs are over lapping mids) but i can fix that just need to pick up some rca cables and hook them up to the sub amps like that rather then letting the full range drive the subs

No, everything under 10hz or so is created my my laptop. I was just doing a test run, if I am going to really look at it I'd break it up into 3 or 4 seperate graphs.
