If you use a higher value, REW will try to boost all frequencies below your target level. For the measurement above, 70 dB is the right answer. You want to get this right, or, not only does REW yell at you, it also will produce too many PEQs to try to flatten the response. It tells REW what SPL (loudness) to aim for overall when it optimizes the equalization PEQs. The last item on this menu is extremely important. In the context of home theaters, that's what a "house curve" is doing. I use flat response everywhere since I unmaster my recordings, but you may choose to use a "one size fits all" house curve to compensate for non-flat EQ used on your recordings. You can boost or cut highs or lows using the above controls, and the resultant curve is visible, so you can see what your "goal curve" is. This is the place to put in your "house curve" if you choose to have non-flat loudspeaker response. The same settings are used for the high end.Īll of these settings are settable to new default values within the "Preferences" menu on the top bar of the REW main window. Set that LF roll off point to match your loudspeaker. If you're using HT loudspeakers, it may be as high as 100 Hz. For my Jubilees and K-402-MEH, that frequency is about 30 Hz. If you look at the measurement plot that you are using to equalize, it will show you the lowest crossover frequency that you should use. LF slope indicates intended the slope of the roll-off of the low frequency end (12 or 24 dB/octave) corresponding to the crossover filter slope used between the loudspeaker and the subwoofer. REW can also help you with subwoofers and "bass limited", i.e., HT surround loudspeakers that are intended to cross above a certain subwoofer crossover frequency.
The important settings here are "Full Range" if using you're equalizing a full range loudspeaker. Now click on the next menu bar - Target Settings: Once you select a crossover type, minimize the Equalizer sub-window by clicking on its top bar again. If you sequentially choose each equalizer, and look at the PEQ filters (which we'll generate in a moment), you'll find one that give you the best fit to the features of your crossover. If using Xilica, then select "XP2040", etc. For example, using the EV Dx38 or Yamaha SP2060, I used "miniDSP", and it works.
You can pick one that's close in terms of your options. If you don't see your equalizer model in that list, fear not. If you click on the first bar, it opens a menu downward and shows you a list of equalizers that are supported directly by REW. On the right top side of the window, there are 5 bars with text embedded in them, namely: Equalizer, Target Settings, Filter Tasks, Modal Analysis, and Resonances.
If you punch the arrow pointed down, the bottom plot is replaced by the upper plot whose size now occupies the space that both windows did. There are two arrows next to the left border of this window. The window has two plots: the plot that the started with (frequency response) and a second plot area (blank) which can provide a waterfall, impulse, or Pole-zero plot.
The next-to-last button is "EQ", which you push, and the following window pops up: So you look at the REW window and you see the function bar across the top of the window: So for that particular plot, you'd like to find the digital crossover equalization filters to make it flat-but without a lot of cut-and-try and doing a bunch of measurements (upsweeps) along the way. What you have is a frequency response that's not quite as flat as you'd like. The results are very close to my commercial plugin chain.Assuming that you have taken a measurement using REW ( Room EQ Wizard freeware), you probably have a plot that looks something like this:
I pair it with Isone Pro which is the free 32 bit version of Isone 3. REEQ was what I was using but I think the excellent free linear phase EQ called Qrange might be better for this application.
Each one is in PDF format with detailed EQ curves (all bands, gain and Q are provided) that can be easily recreated in the EQ of your choice.
He has something like 2500 EQ compensation presets for most major studio grade headphones.
Quite honestly I could mix on the Beyers but I just prefer speakers in most cases.Īnyway I am creating a portable install using nothing but free plugins and came across a nice alternative to Sonarworks from reddit user Oratory1990. Its especially good for checking low end compared to my 6.5" Kali monitors in a DIY treated bedroom. I use it in conjunction with The Toneboosters Isone 3 crossfeed plugin and I'm getting really great results. So I have and use Sonarworks with my Beyer DT880's.
