Save 40 more dollars and get the AQ2200D, its a better buy than they two you listed: Audioque: Amps: AQ2200D

From what I can tell the former stayed attached to the spider, and the cone stayed attached to the former as well. Another thing to consider is that the 13W7 has dual 1.5ohm coils. If they had wired the coils in parallel, that's a nominal .75ohm. Using basic ohms law, P = V^2/R, that would be 120^2/.75 or 19,200 watts of power to the 13w7. If someone takes a D2 sub and wires the coils in series, that's only 3600w to the driver. If someone takes a D4 driver with coils wired in series, that's only 1800w to the driver. Just because it's a wall socket doesn't mean two different drivers are seeing the same power....which leads me back the internet allowing ignorance to spread throughout the masses by uninformed users not considering all of the necessary information before drawing conclusions. MTX used to have a marketing campaign when they released the 9500 series based on this exact principle.....they showed a Solo X, W7 and 9500 being driven to failure while displaying the voltage each driver was receiving.....ofcourse the Solo X and W7 failed at lower voltages than the 9500.....but they never told you what they had each driver wired to impedance wise, which made it impossible to know which driver was actually receiving the most power. Regardless, I think I've already stated on numerous times that the W7 wasn't intended to handle insane levels of power. If that is your desired application then yes, chose another subwoofer. Yes, there are subwoofers that handle more power than the W7. It doesn't make them better; just the same it doesn't make subwoofers that can't handle as much power as the W7 worse. The W7 is capable of more than the necessary amount of power it needs in order to perform at it's maximum in it's intended application. That's all any driver needs. Eh, isn't that exactly what I said? It appears I used the word "application" atleast 3 times, and the bolded sentence explicit says the only time T/S parameters can have a "superior/inferior" inference is in regards to a specific application. For any given application, yes there are. That's exactly what the T/S parameters tell you.....how the driver will perform in a given application.

Fair enough. The 12W7 has an Xmax of 29mm. But Xmax by itself is irrelevant, since we are concerned with the total amount of air capable of being displaced linearly.....otherwise known as Vd. Due to the design of the 12W7's cone and surround it has 542cm^2 of cone area compared to 480cm^2 on the Xcon. So the 12W7 has a total Vd of 1.57L, whereas the Xcon as a Vd of 1.49L. Displacement advantage: 12W7 A driver only needs to have enough power handling to achieve it's intended level of performance in it's intended application. Just because a driver wasn't intended for the application you desire is not a problem with the driver.....it's simply the wrong driver for the application. The Xcon wasn't designed to excel in sealed enclosures. Do I hold this against the Xcon, or simply decide instead to chose the proper driver for the application? The point being there are different applications, and no driver is going to excel at all of them. You are choosing to place significance on power handling for your own personal reasons.....not everybody does, nor should they. So while higher power handling may be a "plus" for your desired applications, it is irrelevant to most others. Last, simply looking at rated power isn't really a valid means by which to even compare power handling capabilities. While the 12W7 may not be "rated" to handle the same amount of power and it may void the warranty, it's design may allow it to do so. So really, the entire topic is moot without more information about the actual ability of both drivers to actually sustain certain levels of power.......other than the fact that running a 12W7 @ 1750w will void your warranty. Herein lies the problem.....you CAN NOT have two drivers with identical parameters other than sensitivity. It's not physically possible. So your hypothetical scenario is completely irrelevant as you can not "choose" an identical driver with higher sensitivity. If you really want to know why sensitivity is NOT a "higher is better" type of specification, here is an article in the tech center that will help you understand the trade-offs associated with increasing sensitivity; Subwoofer Sensitivity - SSA Car Audio Forum Exactly. That's not evidence of anything other than your own personal opinion, which is irrelevant to the discussion of the performance of a driver. Even then, we could question the validity of the experiences which you used to form your opinion. The performance of a driver is impacted more by the system, enclosure and environment than the actual driver itself. If your experiences with the W7 were heavily influenced by those factors (i.e. listening to a W7 in someone's vehicle, in a showroom, etc) then you honestly do not have enough experience with the W7 in order to form a valid conclusion and comparison of it's performance to any other driver. So, have you ever compared the W7 to a Xcon in identical environments and identical alignments and identical systems in order to form a valid comparison of the two drivers subjective performance relative to each other? If the answer is no, then "your opinion" is quite simply irrelevant and your experiences are inconclusive. That says nothing negative about you personally, it's simply a matter of fact. All opinions are not equal, and all opinions are not valid. Despite popular belief, an opinion can indeed be wrong.....or atleast, be based on faulty information. T/S parameters are not a "superior/inferior" type of parameter. They simply describe the low frequency performance of a driver, which assists the user in determining which driver best suits their application or what application would be most appropriate for a certain driver. The only relevance T/S parameters have in a "superior/inferior" inference is with respect to a given application. Look at the video closer. They don't have the ring on the surround, which means the surround is not attached to the basket. It appears when they applied power the coil rocked as a result, which hit the gap and began to bounce around thereafter. That video doesn't show anything other than a broken driver doesn't function properly. THIS is a prime example of the problem with the internet. People "see" something without fully analyzing the situation or circumstances and then use this misinformation to draw conclusions.

HAHA. Do some research and go ahead and just email Fi for a recone. Why do people think the gain knob is a volume knob? If it was a volume knob, then it would be named a volume knob.

could this be a marketing hipe or a person that wishes they have a ssd????hmmm...

ya i mean great answers really.....anything from 1 watt to 1 billion.....puts pinky to lip*.... these subs are sick man......lol how can we know where we are going...if we dont know where we have been ????? and i know for a fact you can get more out of these subs in other installs....thats not what im asking either.......wtf is DR phil when you need him.... i want the testimony of bl owners and what they did with their sub or subs....not a bunch of crap about how it depends on the install....that is not irrelevant... due to the fact that all info could aid me or others in furture installs......i want to kow the whole town...not just my street....

the heatsink is very...dainty... overheating, breaking, i see this all in the future
