I know that comparison between two subs (improperly calibrated) is useless.
what's wrong with me.
If we are to scientifically measure subwoofer speed. what is the measurement to be used? Does REW have that feature?
I hope that maybe gain control on SVS was too low. and that made SVS less impactful than it is supposed to.
I think what you're asking about is a waterfall chart that shows how responsive a subwoofer's reproduced sound, interacts with a room's acoustics; decay and echo. Anybody is welcome to correct my above comment as they find necessary. Below is an open plane waterfall graph for a PB13-Ultra.
The above does not take into consideration the room acoustics of a listener's Home Theater venue.
The thing that I think is missing when one asks, "what's wrong...", the two subs are totally different subs regarding performance and output.
How much is the JL113 vs the PB13-Ultra? From what I see online, the JL113 has 2,500w RMS vs 1,000w RMS for the PB13-Ultra.
I'm seeing $4,000.00 CDN for the JL113.
Reading further, I see that the JL113, refers to the amplifier output at "short term" which in my opinion is code for peak output. The point, when one uses semantics to jack up their numbers, that's what they're doing, inflating their numbers to make themselves look good.
Think of it like a long distance runner. Cross country runners like to say, our warm-up is a football player's punishment where the heart rate doesn't start to level off until after the first mile and a half and ones doesn't lace up unless going out for three to six miles.
Personally, due to a desire to smooth room response, I'd buy three PC-12 NSD's before buying a single, uber powerful subwoofer.
Personally, if paying with Canadian dollars, I'd buy Funk Audio.
