Subject: JBL 2226 is not intended to be a subwoofer driver


That's a very efficient pro woofer with an FS of 40Hz.
which is about an octave too high and and XMAX of
only 7.62mm which is about half of what you should look for. The 15" Adire Audio Tempest driver I use with an FS of 19Hz. and DUMAX of 16.4mm would be a much better choice for a subwoofer driver. It would easily outperform the JBL 2226 and only costs $150.
I'd guess the 2226 price is at least triple that amount. I strongly doubt that JBL's product literature recommends the 2226 for use as a home subwoofer driver.


The low distortion specs for the JBL have been misinterpreted -- they only apply to 100Hz. to 500Hz.
which are well above subwoofer frequencies.
Distortion at under 50Hz. is probably much higher
(although output under 30Hz. is likely to be weak unless boosted a lot by cabin gain). Very few people could hear subwoofer harmonic distortion under 5% while listening to music -- often 10% distortion is required before most people would notice. That's one reason subwoofer maximum output tests often use a 10% harmonic distortion limit. Paying a lot more money for a pro woofer to reduce already inaudable harmonic distortion by a few percentage points may please the owner of the driver, but is probably not an audible improvement.
