Some add-ons I figured out this weekend or forgot to mention:
1) The problems occur at louder volume/listening levels,
2) Problems also occur with louder music (louder as in
typical rock music vs. mellow or acoustic music)
These two points may be obvious to some…
3: I do have speaker isolation planned with bamboo boards (some
would call them cutting boards from Ikea..) to put on the carpet and then the
floor spikes.. Haven’t added them on yet
as I am still scooting the speakers all over the place testing different
Ok, so here’s where things stand:
1) Let’s get this out of the way 1st… I tried to not so discreetly allude to the
fact that this room is already wayyy over budget… So far over budget that had I known what the
room itself was going to actually cost I would have had to at minimum
drastically alter my component purchases (which in hindsight could have been
done differently but what’s done is done…) or forego the project altogether… If there is a comma in the price (e.g., $1,000+…)
it is not gonna happen. As it stands,
anything that costs a couple of hundred bucks brings out a heavy sigh… Not complaining, just stating the facts as
2) GIk agreed that my speakers close to the front wall is an
appropriate placement. I was so focused
on making sure I was giving accurate information I forgot to dive in to the
logistics of why this works but regardless, he agreed when I said it sounded
the best so far…
3) Need to get those panels
constructed and hung
3a) still investigating best
placement for the panels. It seems the 1st
and 2nd reflection points are the main idea here but honestly, they
both may be covered by a single panel.
Ironically, my wife doesn’t have a small mirror in the house so have to
go find one. Should this be correct, this
opens up the option of placing some panels either behind the speakers on the front
wall or on the back wall (keeping in mind I am talking about panels, not bass
4) Seems to be a pretty common
consensus that bass traps need to happen so I will get on this.
4a) spoke with GIK and got
recommendations (very helpful by the way, just as many have mentioned) basically
it comes down to me being on the right track with the panels and adding bass
traps in all 4 corners of the room. The
total is approximately $700 but I can’t tell exactly as the website and my
computer are not playing nice with each other as I can’t add the traps to my
4b) I need to investigate the DIY
route for building bass traps and am still looking for recommendations for
material so I can compare prices with GIK.
It seems the OC 703 could be a component but either need to use it in
combination with something different (alternating 703 and 703 FRK) or use
something different altogether. If I am
reading correctly, it seems something with FRK needs to be involved so the bass
trap doesn’t suck the life out of all the mid and high frequencies… Thoughts?
4c) triangular pattern that stacks
up on top of each other (pancake style) vs. panels that are simply placed in
the corner. It seems the triangle option
has more mass and therefore should absorb lower frequencies and do a better job
overall when compared to panels placed in the corner. Am I interpreting correctly? Cost/benefit?
4d) as I stated earlier, I don’t want
to be that guy that plugs a business for information and then goes somewhere
else.. I need to do the aforementioned
price comparison and if it is comparable, or at least somewhat in the ballpark
of reasonable, I will use GIK but if there is a big difference then I gotta
consider the alternatives..
5) components on the table – I can
see how the table might be a reflector o’ sound and I do have a small rack
style stand (3 shelves, maybe 2.5’x2.5’x2.5’) that I can easily swap in. Thoughts?
6) Did some research on what was mentioned. My interpretation: Room nodes/modes = 2 “beams” of the same
frequency meet and either create a peak (in phase) which amplifies the
frequency or null (out of phase) which negates the frequency and cancels it out..
there’s a lot of math after this… At
this level, it makes sense. Am I correct in my interpretation?
7) @auxinput, thanks for the graph/chart. I honestly can’t say that it all makes sense
to me but from what I can decipher (as demonstrated in point #5 directly above)
it seems the bass traps and panels will be a big part of the solution, if not
the solution.. is this an accurate interpretation?
Again, my deepest gratitude for the input.. It seems like I am making some headway, at
least in theory at this point.. By all
means, I am still open to input so feel free to chime in (but please make sure
you read point #1, the second one, above)
