Wow, some kids just never learn...
A W7 of the same size as an L7 will annhiliate the L7, in every way, shape, and form in a musical application, everytime.
Now realize that SPL scores prove NOTHING. They are taken at the ONE frequency that peaks the highest, with no regard to distortion.
Now you may be able to hit 145, but can you hit 145 from 10-80hz? Doubtful.
The distortion on the L7 will skyrocket as you go lower, and if you try and send very much power to an L7 below tuning, it will rip itself apart rather quickly.
You kids really need to learn to study physics, so you don't look so stupid.
It is not even a debateable subject as to which woofer can produce more broad bandwidth SPL, yes, across the ENTIRE bandwidth of the subwoofer, not just at one frequency near box tuning, because that requires far less displacement.
If you want to say that an L7 can actually beat a W7, you need to prove it with music, and you need to prove it across the whole frequency band, not just at one farted frequency for a brief second, because all that says is that in one specific SPL application, the L7 can fart louder. NEAT. That proves nothing.
You have to be severely deficient in intellect or just incredibly brainwashed to believe that SPL scores translate in any way, shape, or form to real world broad bandwidth musical output, because they don't. In the real world, SPL IS dictated by displacement.
So apparently you are saying then that the L7 defies the laws of physics? I would really love to see proof of that. Maybe you'll just put your foot in your mouth now and shut up...
Lastly, ever heard of Nate Munson? He managed about 170dB with a single DD 9510, and he swapped in a W7 and got the same score. Hmm...now if the W7 sucks at SPL, how come it did just as well as the 9500?
You can't even defend your argument that the W7 can't get as loud, because there is no logical explanation for that, because it is FALSE.
You cannot compare SPL across two different installs, because SPL scores are NOT measuring the woofer, rather they are measuring the sum of the woofer, enclosure, box, crossover, amp, head unit, vehicle, competence of installer's work, etc.
That is FAR from a fair comparison. You must compare both drivers with all other variables equalized, otherwise your claims have no strength, because you completely failed to prove your argument. You must test the woofer and ONLY the woofer, to actually compare the two.
SPL competitions fail miserably at this task, and even if you do equalize very variable, all the scores tell you is which driver gets louder in a given SPECIFIC application, with a given amount of power.
That is precisely why you use objective means to compare, rather than highly subjective and completely invalid means such as SPL scores.
Hope that was educational, hopefully you'll actually think about it instead of remaining woefully ignorant... //content.invisioncic.com/y282845/emoticons/wave.gif.002382ce7d7c19757ab945cc69819de1.gif
