Hi all,

My name is kristo, and this is my first time here! I'm currently in the process of building out my sound system for two purposes: (a) for at home daily listening, and (b) for use in a small "party" like setting, where music is the focus and is used to provide an emotional experience over a night (as in, it's not just about dancing or feeling happy the whole time).

At the moment I own a set of Klipsch Cornwall IIs, but I will soon be purchasing a pair of Oris 150s and MiniDSP ICE125 (DSP + amp) for the low end. Initially, the Oris horns will be sitting on top of my Cornwalls and I will use the woofer in that enclosure with the Oris horn. Eventually I hope to expand to a 4 point system with custom bass horns. We'll see.

Anyways, right now I am taking my first stab at making my everyday listening room sound better. It currently feels bright/painful at higher volume levels and with more active music. I got a mic and REW, and here are my first measurements taken at listening position. I'm curious to know what y'all think.

SPL in the bass frequencies

SPL 20-20k Hz, 1/6th smooth

Waterfall 20-400hz, 0-500ms

Full Waterfall 0-300ms

Now, this is my first time interpreting these graphs and I have very little in terms of reference, but this is what I gather from them:

• Significant room mode around 48hz - can be cured with my DSP when I get it?
  
• Significant null at 100hz - also cured with DSP?
  
• The frequency response 100hz+ seems generally ok?
  
• I have significant issue with decay time at all frequencies, which is what I expected. I have concrete walls and floor/ceiling behind a layer of sheetrock. To fix this I should employ absorbers and diffusors on walls and ceiling, as well as a rug. Does that seem right?

  So I think I have a long way to go... which is comforting because it confirms what my ears were telling me . Do you all see anything else I should notice from these?
  
  Also, here is a pic of the room so you can have some context:
  
  
  
  Cheers,
  
  Kristo
