...underscoring the value, I guess, of doing these types of comparisons? BTW, should be noted that the only thing changed from iteration to iteration was the target level. Frequency range (16–140Hz), maximum boosts (+10dB individual/total), and flatness (±1dB) remained the same.

I turned to REW's EQ tool for a more objective reference to an MSO target level. Based on an average response of the seats I will be feeding to MSO, REQ calculated a target level of 82.5dB (range 16–140Hz). I then ran a couple more equalizations at 85.0dB and 87.5dB to see how they compare...

As this is where I first learned about configuring my Mac to accommodate the Marantz CINEMA 50 I’ll give the following a whirl… Went to do some REW work and started with level check...only to have front left signal coming out of rear surround left. Before you ask, the cabling is fine, playback...

Thank you John, I suspected as much.

I don’t know if this is a MacOS or REW setting that I need to resolve. When connecting both a miniDSP 2x4 HD and UMIK-1 to separate USB-C inputs on my Mac, only the miniDSP appears among the REW inputs. I can’t access the UMIK-1. Same on the Mac MIDI Settings utility. Given both devices are...

Crazy how room changes most would give a passing thought impact acoustic measurements.

Thanks, mate. With that in mind is there an advantage one way or another (phase vs IR) for calculating sub alignment delays?

Having developed some familiarity with the Alignment Tool phase section through crossover testing I’m trying to understand the IR function. To align IR at cursor, what cursor position would you select and why?

I use this one (USB C-C, 10’) with my MacBook and works well, built well. I didn't want an extender, just a nice clean single cable.

Wild info, thanks!

That is a good guide. Using that approach—assessing falloff points—I ended up with some wildly different values than the defaults. Haven’t had time to test them, or use REW to document actual response. I still wonder if it’s worth the effort to chose an escalating series of XO’s in DLBC (70...

Loaded the new settings, answered part of my question—indeed DLBC replaces the AVR’s crossover points with their own (or whatever you selected). Now I need to understand what informed DLBC’s “recommended” crossovers, and would inspire me to set them otherwise.

Hey J Failing to find an answer perhaps you can offer some insight. Just loaded DLBC for my Marantz Cinema 50 today and going through the additional features in the software. I'm confused about crossovers; on the one hand the DLBC documentation says it "guides" the user in their crossover...

Hey Folks Took delivery today of two SVS PB-2000 Pro's for my dedicated room. They occupy the front left/right front corners between the mains and the adjacent side walls. I ran through a preliminary setup this evening with REW (fed by a calibrated UMIK-1 and into a Marantz Cinema 50 via HDMI)...

Hey Folks Looking for some advice on room dimension reference where using the REW Room Simulation tool (or acoustic tools otherwise). My (16x23') theater has an 8 foot central ceiling height...but there are 40" bulkheads around the perimeter with 7 foot height. The overall surface area is...
