Guess How Big My Speakers Are

Whatever they are they need some EQ below 500hz. There's been at least 5 guesses. 

We’ve reached the 5 guess threshold.

While I am a fan of Monitor Audio, that guess was wrong, as were all floor standers. "Large monitors" with 8" woofers was also incorrect.

Also incorrect was "long throw."

The in room response you see there is generated by a 2-way ported speaker with 6.5" mid-woofers from Scanspeak. While highly regarded by makers like Fritz, YG and Wilson, I wouldn’t classify them as particularly exotic.

The main point I wanted to make though was that, with room gain, a lot of speakers go lower than we think. Maybe not as loud as we’d like, but the output at 20 Hz is not nearly as far down. Room treatment helps make t his possible by damping down the mid/hi frequencies in the room, otherwise this response would probably go upwards.  Maybe a speaker that measures down to 40 Hz on paper is actually good enough for a lot of locations.

Would I add a sub? A question I debate a lot lately. If I did though, given how much output I have already I’d surely have to introduce a high pass filter. Adding a sub without one would be madness.

I was gonna guess Fritz, but now I’ll throw out Selah as a Hail Mary.  I just hope the performance graph of your investment portfolio looks different from this.

Fritz tunes his speakers for more punch, with smaller cabinet sizes.  These sound a lot more laid back by comparison.  I will say he is using what I consider among the best sounding mid-woofers on earth. :-)

They look real good >1khz I would smooth the peaks a bit <500hz with EQ. I thought they were  3 way Bookshelf with that much bass.
