There's so many aspects of a subwoofer design (total amplifier power, amplifier's distortion handling, woofer size, woofer's excursion handling, cabinet size, cabinet damping, electronics, etc).Silly question:My current sub is from 2006 but the main specs are:
Frequency response 30–200 Hz
(at maximum crossover frequency)
Crossover frequency 50–200 Hz (variable)
Maximum output power 150 W Dynamic
20 cm woofer
Some of the new subs today seem to be the same or slightly less on some of these specs eg the Klipsch R-8SW which has a FREQUENCY RESPONSE 38Hz-120Hz +/-3dB
150W max dynamic output, same size woofer
Both are down firing
Is the Klispch a better performer simply because of the brand and/or because its newer even though the specs are no better?
Without measuring both subs using the CEA-2010-A standard, we can't say for sure whether the newer Klipsch is a better performer than your old sub.
You can't assume that because one subwoofer is a newer design that it's automatically a better performer.
We need to test both subs, ideally.
Also, reading manufacturer's website for information like 'peak power' or 'frequency response' is meaningless. Since we don't know what these values mean, practically, it's useless information.
The only useful information you can get from a manufacturer's website is the size of the woofer, whether the design is ported/sealed, and cabinet size (volume).
Which gives you an indication of their output capabilities (peak output and how low the extension is).
The only true test of a subwoofer's performance is the CEA-2010-A since there's no way for a subwoofer to cheat this test. If there's not enough output for a given frequency, that's it. You can't make a 8" sub outperform a competently-designed 12" sub.
As they say "There's no replacement for displacement", which means woofer size is an indicator of performance.
But of course, not all brands are created equal. Certain subwoofer companies maximize performance for your dollar, while others overcharge you. And most subwoofers are just awful.
My spreadsheet allows you to find out how good Klipsch subs are (tip: they're not very good), but more importantly find better performing subs, so you're not wasting your money.
