Makes it hard to adjust the speaker position

I believe he must have position & tested location prior to the build. Lol

I wish there was a link to the source material being played - so I could (possibly) hear what it would sound like over my own system.

I don't think there is a big difference, between BH with Fostex 8" driver and TQWT with MarkAudio 5" driver.

Well to my ears there is a big difference.
Its sounds very open, big & effortless.

you guys beat me to the song! 🙂

Great!

Generally, 8" BH has a large box, but under 50Hz is little poor.

Yikes! A 40dB drop between 50Hz and 10kHz?

 

[nandappe]

Dear perceval,

For music sources, -40dB is normal at 10kHz.
Please download WaveSpectra (real time analyzer) and play your favorite music.

FFT setting is recommended with 16384 sample data and the window function Hanning.

Got it!

Somehow, I thought it was a measurement in your room.
This is the mix of the song.
Thanks!

Perceval, I don’t think you were the only one who thought that.

#10, the top image is frequency response of CD.
Under three images are frequency response of playing speaker in each room.

The near microphones are, the greater the proportion of high frequencies.
