I’m looking for a sub that has left and right RCA in and out, and further that acts as an active crossover (thus not sending the bass that the subwoofer is handling to the main speaker amps). The reason for this is that I have a great stereo pre-amp with only one pair left and right RCA...

Im looking for advise on what PEQ filter I need to flatten out the response of my DIY sealed Dayton UM18. I thought ARC was going to take care of it but it did exactly what it is suppose to do and it flattened out the peaks but didn't really change the response of the sub (which I want in this...

Hi all, I would like to share two articles about reading phase response and FIR filter correction. Phase response. Understanding Different Views and Thoughts of Phase Response Curves. http://www.prosoundweb.com/article//a_meaningful_loudspeaker_phase_response/ PDF version...

I know theoretically I can apply a filter to whatever frequency I like but I have read that I should really try to apply filters to the lower frequencies. I cannot recall the exact reason for this. Assuming this is still sound advice, for practical purposes, what is the highest frequency I...

Hi, I have done my first measurement and here is my result..It is with Audyssey ON but with DEQ OFF at 85dB- I would like to generate EQ filter for my mDSP2x4 to try first so i dont want to run a Audyssey calibration again. I have attached my mdat. file here could anyone please create a EQ...

Hi guys, I am in the final stages of producing a 3-way pair of stereo loudspeakers which have a flat baffle. I want to try and use the new acoustic reference feature in REW to allow me to accurately measure the impulse response and phase of each driver at the microphone reference point (1m...

Hi, Read this interesting article on minidsp.com - is this applicable on my SVS-SB2000 which is a sealed sub? Are there any pros / cons related to this (e.g. loss of headroom)? Best regards, Peter

Hi all, im testing out room eq wizard getting used to it in a live venue i work. I dont have a measurement mic yet so im using a condensor with a fairly flat response until i get one so maybe this could be the issue,but i suspect that its something im doing wrong. baiscally the only filter...

Anyone try a Neutral Density filter on their projector to improve black levels?

Web based audio tools: Brutefir online (router), Convolver Hi, I've just coded a simple page to make real time audio convolution and also offline convolution to download the files (working with chrome and firefox not tested in others). I hope it will be usefull: http://jsgsound.com/convolver...

Hello everyone. I've been getting the hang of REW and would like to get some critiques regarding my before and after EQ curves. My concern is the very narrow (0.200 BW OCT) 9db gain at 55hz to treat that null. Is that okay? I also have a very narrow and deep null at 270 hz, could this be an...

I've long wonder about this and was once again trying to figure out what the right way is to tweak a filter set after an initial filter set is sent. I am using the BFD 1124. Here's what I do now: 1. Take measure 2. Go to EQ window 3. Click Set Target Level 4. Click Send Filter Settings to...

Is there any kind of discussion out there on filter types and slopes, advantages / disadvantages? I recall from my passive crossover days that certain filter combinations had certain characteristics, and I assume the same runs true for active dsp crossovers, but I'd be interested in a good...

Sorry if this question has been asked and andwered before, but why is it every time I run "match response to target" I get a different set of filters eventhough NOTHING has been changed on the parameters. It is frustrating especially since I have to manually input all the setting each time into...

I see I only can setup a 20 band EQ filter using equalizer type generic. Currently I load 2 saved profiles, 1 for low freq & the other for high freqs. Isn't a 31 band eq not somewhat common?

Hi all, I am trying to EQ some nearfield studio monitors via Cubase 7 recording software in my home studio. Cubase 7 comes with Reverence reverb that I can use to load IR EQ filters created via the REW export function. I am having difficulty getting the IR's created by REW give full width...

I am just wrapping up the design on a subwoofer build for my brother. I decided to go with a Dayton Audio RSS390-HF in a 9.65ft3 ported box tuned to 15.6hz. I was planning on using a BASH500 amplifier but I need to modify the amp's HP filter. Any suggestions on what to set it to and the proper...

Hello, I am using REW v5.01 Beta 20 in windows 8.1. I use Acourate to generate FIR filters that are then used in the JRiver convolver. Is it possible to measure the room response already corrected by the Acourate filter? I would like to measure it (keeping mic, etc, fixed) so I can compare...

Hello, I have two Subs in my Equipment with own dsp-moduls. One left and one right. Which precedur is better: Measure both subs together an use one filter, or Measure the subs alone, create filters for each individual? Best regards Harry
