To paraphrase Floyd Toole, 'I've never had a speaker that sounded good that didn't measure good, and I've never had a speaker that measured bad that sounded good'.

BTW, I did get around to measuring the specs on the drivers in my F34:

BMW Hi-Fi Woofer

Fs 51 Hz
Qes 1.00
Qms 3.02
Qts 0.75
Vas 18.4L
Re 2.4 Ohms
Le 0.22 mH
Sd 200 sq cm


BMW Hi-Fi Midbass

Fs 117 Hz
Qes 1.17
Qms 3.56
Qts 0.88
Vas 3 L
Re 3.2 Ohms
Le 0.23 mH
Sd 35 sq cm

If you know what these specs mean and how to use them it's obvious that these drivers are quite good. If not then you're a perfect customer for after-market drivers that are long on promises but short on facts.
