 Sherv,
Do you have any hard data/evidence to prove either of these claims? 
Here are the Ultra/2 numbers measured by Ed Mullen. They are 10% THD instead of CEA-2010 but almost everyone is amp limited, meaning max output. Compare these to PB13-Ultra numbers.
20 Hz Tune 10% THD Ground Plane 2M:
16 Hz: 89.5 dB
18 Hz: 100.7 dB (8.4% THD amp limited)
20 Hz: 102.8 dB (9.4% THD amp limited)
22 Hz: 104.9 dB (7.7% THD amp limited)
25 Hz: 106 dB (6.2% THD amp limited)
30 Hz: 109.5 dB (7.9% THD amp limited)
40 Hz: 113.1 dB
50 Hz: 112.2 dB |
no unfortunately Ilkka....two years ago I didn't get a chance to measure this sucker, and unfortunately no longer do I have it.
I told you, you need to move to the US and leave that forsaken place you are in!!!
If so, you could have had all kinds of fun with many DIY speakers around here.
