Jbl target curve "A flat in-room target response is clearly not the optimal target curve for room equalization. . The light dark green is prior to application of the response curve/EQ and the bright green is post equalization measurement. Figure 6: JBL Synthesis "ARCOS" room equalization target curve shown in gray dashed line. Home Theater: JBL M2 & SUB18 powered by Crown and BSS. Basically the target curve is just a starting point. I haven't found a clean picture to plot out the curve like I did with the Harman Curve yet. Here is a link to a house curve article by Wayne Pflughaupt. This thread may spur some discussion, or it may not. The important thing is to be consistent in your measuring as you develop and refine your own curve to your own liking. Here is the target curve (in dashed lines) for JBL Synthesis Arcos system for the main speakers. I often see people ask about what final "curve" they should tune their system to. The preferred room corrections have a target response that has a smooth downward slope with increasing frequency. Update and summary so far in the xls. Matches very well ECM indeed. I also researched the topic and found the JBL curve, house curve, etc. I also researched the topic and found the JBL curve, house curve, etc. Tested with Blue Note 24 192 Maiden Voyage, cymbals were a bit to prominent so I keep the JBL Synthesis recommendation. Benefits MFSL with better snares, more punchy bass notes and of course presence and brillance. So if I set my gains for a 3 way active system with all EQ settings and levels flat/0db for each network, and using a -5db test tone @ 4khz for tweets, 400hz or 1khz for mids & 40hz for the sub, then start to dial in (for example) the JBL target curve with a +9db between 20-60hz, isn't that much of a boost going to cause a clipped signal? ARCOS compensates for these irregularities faster, with greater accuracy and comprehensiveness than has been available before, to achieve a target curve based on listening tests and hundreds of calibrated systems to provide extraordinary sonic realism. You see responses range from things like: flat, "smiley face", ELC (equal-loudness contour), gentle slope downward, the "JBL Curve" (provided by Andy W. Looks like a 5 dB drop from 80 Hz to 20 kHz: View attachment 10873 The faint gray is pre-correct, the blue, post correction. This tells us that listeners prefer I'm currently researching the JBL Synthesis curve which appears to have 2dB less of a rise from 160hz to 40Hz compared the Harman Target Curve. ), etc It's an HF extended JBL Synthesis flat from 3 to 20 K. I When my gear is set up up, I am going to try the Synthesis Curve, a flat curve, and a Synthesis-like curve without the bass boost. ucsjj hvupe frwsfr lfox cebh vzkzm kszltx mpowtl watmauh iwcz
