Do you use a Schumann Resonator?
Do you use an air ionizer in the room?
If you have carpet on the floors, do you vacuum
it before critical listening?
Do you treat cables, components, speaker cabinets,
and walls with anti-static spray, applied with a moistened cloth?
(Also great to spray on carpet, before vacuuming!)
Do you use a Walker Talisman?
What you aren't saying may be more important than
the information you are sharing... a different perspective
is sometimes all it takes.
Check out the GIK bass and soffit traps, they will help room correction work better.
Set your main speakers to small.
Turn off room correction. Put your sub in your listening location, then walk around possible placement locations until you hear the best bass. Put your sub there. Re-apply room correction.
Thanks Erik. I do have a couple of the GIK Bass traps (just two, one in the corner near the sub, the other in the opposite corner). And I don't think I can add any more traps or panels if I want to preserve my marriage....
Interesting idea to set the main speakers to small.
The sub is in pretty much the only place I can put it -- though I've done the 'crawl' and I think it may be in the best location already anyway.
Perhaps I'm using the term "visceral impact" incorrectly. It's not so much the "boom" at the very low end... it's more about the fact that the system feels a bit recessive overall, or not as "forward" as I'd like. Said another way, it doesn't make me want to _move_.
Replace those B&W with super large JBLs - done.
And yep, after a bit more Googling, I see that I definitely used the wrong term. I'm looking to help improve presence, and help the system feel a bit more forward.
I certainly agree with all the recommendations noted thus far. I know you said you were happy with your current gear, but looking at your system, I can't help but think your current Sub is the weak link here. If tweaking the room acoustics doesn't get you where you want I would seriously consider replacing your current sub with something like a REL t9i, or better yet a pair, would certainly get you closer to the visceral impact your looking at. RELs will also give you better imaging, depth of sound stage,a and will help with the "there-ness" you're looking for.
I agree with birdfan.
Multiple subs would contribute to a more even distribution of bass impact, as well as more bass volume.
Thanks all. Reading a bit more about "forwardness" and "presence" it seems more like the 1khz to 3khz range tends to be related to what I’m talking about.
So I really don’t think the issue is <60hz... and therefore probably not a subwoofer issue. (and unfortunately I also don’t have the space for a second sub, nor a larger sub...the Monolith 10" is already quite a beast!)
Your main speakers lack impact/presence for two channel, right? Too far apart is no good. Placement/distance to seating area next big thing. Can you use XLR’s? If so, try some good musical cables like MIT or Audioquest. Actually, the speaker cables will make the biggest difference and MIT technology really shines in that area. Best bang for buck in an unbelievable power cord bargain/performance is the Anticables Reference at $330!! Absolutely stunning.
Vacuum your carpet before critical listening? really we are going there now. Next we will have threads on what vacuum sounds the best.
I thought you couldn't hear anything in a vacuum. 😄
As for the OP's dilemma, if only you could just sit closer and move those speakers closer together.
All the best,
glennewdick, if you can't hear a difference,
then there is no difference. simple as that.
suggestion: don't do it.
All speakers should be set to Small if your sub is competent.
it seems more like the 1khz to 3khz range tends to be related to what I’m talking about.
Audyssey’s default adds a 3dB dip at 2kHz, so that’s likely the issue (it also lowers bass). Buy their $20 app and correct the response by turning off Midrange Compensation (MRC) and adding back in the bass. So, it should go from these presets
to something more like this
(tweak with it).
Yours has the older version, which has Audyssey Pro; which was basically a more advanced version of the $20 app, but costs $200 for the Pro kit
:( and I don’t even know if you can still buy it.
My Denon also is too old for Audyssey’s app, but I have a measurement mic so I manually adjusted the built-in 8 or 10 band EQ for each speaker instead, as I disliked that dip.
Maybe I'll just tinker with the EQ manually, too... Looks like I might be able to "curve copy" to use the Audyssey EQ results as a starting point?
I also emailed Marantz to see if they had any suggestions on further apps/adjustments. Thanks!
Heard back from Marantz. Nice that they replied quickly, but otherwise no luck.
"Unfortunately, no. The 8802A didn't have the proper hardware to support that App. As far as any other Audyssey Apps for older models, I don't know of any.
"There may be some 3rd party Apps to calibrate for room correction, but it wouldn't work in conjunction with the Audyssey software built into the AV."
Yeah, curve copy, boost 2kHz by 3dB (or to taste), boost 500Hz by like 2dB, boost 250Hz by like 3dB, boost 125Hz by like 4dB, boost 63Hz by like 7dB.
Treble is also a little off, drop 4kHz down by like -3dB, 8kHz is sorta where it should be, 16kHz should be boosted by like 3dB.
Harman’s target curve is for like a young-ish male, older people or people with more music exposure may want slightly different results:https://youtu.be/ySQV5OR71e4?t=1m43s
Here are their latest findings (to my knowledge) on average preferred levels across different people categories.
I think you are referring to dynamics? There are many ways to improve on this, but it would mean upgrading some components.
Check phase to start. Is impact with a good recording better with or worse with one set of speaker connections reversed? If not then everything is in phase.
could you incorporate some of the Mini Dsp units?
