Guess How Big My Speakers Are


If you read any of my threads on here or looked at my virtual system you probably already know the answer to this question, but for those who have not, try this as a thought exercise. Given this plot alone how big a speaker do you think this is?

Frequency response plot showint extension to 20 Hz

 

Hints:

  • 2’ from sides, 1.5’ from rear
  • Ported
  • Not horns
  • No EQ applied. This is the natural in room response using short sine sweeps.
  • For a living room this is a well treated room with GIK soffit traps, bass traps and diffusion panels strategically placed.

I’ll reveal my answer if we get 5 guesses or more. :)

Sir, you can't handle my waterfall plot. 😂

@erik_squires what is the volume of your cabinets?   I too run Scanspeaks in  ported but don't have your measurement equipment to compare to my room.  Your stated dimensions are speakers / position.  What is room?

I pretty much stole the cabinet from the Klang/Tong Nada if memory serves. Quite a large cabinet really.  However, I deviated in my crossover design from normal practice by NOT making measurements quasi anechoic but in-room for the bass. As a result the room gain was taken into account then. Even so, I still think I should have considered a smaller cabinet for a bit of low end punch.  Nothing I can't fix with EQ and proper placement though. 😁

 

Are they 1cubic foot bookshelves? Say, Squires hrs-1..... Or something like that?
