Well I’ve been learning a lot playing with my new system. After more time spent with it, I think I’ve come to the conclusion that my room needs some EQ help that my Onkyo’s AccuEQ can’t seem to provide. I’ve spent a lot of time tinkering with my subwoofer (placement, volume levels, crossovers, and AccuEQ’s presets) and was still dealing with harsh bass that had me reaching for the volume dial.
I finally downloaded a SPL app and played with YouTube test tones using C-weighted measurements. With EQ off, I quickly realized my low frequencies were all over the place. With EQ on, any improvements were minimal at best. From what I’ve gathered, AccuEQ in my Onkyo simply develops three random presets for you to choose from (with no visible data of what you’re selecting). For manual adjustments, it’s incredibly primitive. For subwoofer levels, all I can adjust are 25hz, 40hz, 63hz, 100hz, and 160hz frequencies. Regardless, I used YouTube test tones again and tried to balance these out (excluding 160hz since I’m crossing at 100hz). This resulted in a noticeable improvement. A lot of the harshness in my bass went away and my system sounded much better overall. I haven’t touched any higher frequencies yet, but I’m sure they’re off as well.
The fact that I can get better results with my iPhone and basic adjustments has me obviously disappointed in AccuEQ. I believe my TX-NR747 is right when Onkyo ditched Audyssey so it’s likely 1st gen tech. This has me looking at Denon receivers so that I can get Audyssey. Realistically, all I need right now is the X1500 for $399. However, I can’t get MultEQ XT32 until the X3500 for $699. I’m trying to determine if the X1500’s MultEQ XT is sufficient or if I should spring for the XT32... I’m really interested to know if Audyssey can help my system. As I mentioned before, I’m limited in what I can do for actual acoustical room improvements. I am planning to add an area rug to reduce my hard surfaces, but that’s about the extent of things.
