A few questions regarding room treatment for bass

[FireEmblem]

How do you treat bass with absorbers in a room where corners are occupied by furniture or other architectural difficulties (like a small wooden threshold for the windows/glasswall)?

Are there other ways or are corners really the only way to effeciently tame modes? Also, can one get along with 10 absorbers for two corners at the price off 55€ per set (2x each, on Thomann, made of foam) or do bass absorbers usually cost several thousands to be really effective?

Edit: These are the ones that Thomann is offering under "bass corner traps":

They also have a version with wooden parts:

These are 79€ per pair, and go from 80-1000Hz as the page states.

But I cannot put them in the corners, except one, the other corners are occupied / blocked.
They also offer these for the walls

Unfortunately there's no info about how low they go. It only says 100% polyester core.

I'm not an expert and I don't have any acoustic treatment in my home theater/living room...

As always, "Diagnosis before treatment". Get a measurement mic (about $100 USD) and REW (free.)

EQ/room correction can help with the standing wave anti-nodes where you get peaks in frequency response but EQ is not as effective at nodes where the waves are canceling. Luckily, the peaks are more annoying than the dips.

do bass absorbers usually cost several thousands to be really effective?

Not necessarily but bass traps need to cover a significant amount of the wall area to be effective, so the costs will add-up. (Regular acoustic panels don't work for bass.)

There are (at least) 3 kinds of bass traps.

- Traditional "thick" traps which are just thick absorbers. In most homes they take-up too much room space to be practical.

- Helmholtz resonator traps, which are also bulky.

- "Thin" resonant traps like those sold by RealTraps. Ethan Winer (one of the RealTraps founders) has a DIY article: Build A Better Bass Trap.

That guy knows a thing or two about traping bass.
