There is no war here, there is simply a discussion.
On paper the RL-P appears to have an advantage, however reality beats theory On another note. I know the RL-P drivers were designed for car audio.every time. Anyone familiar with JL as a brand knows their specs are extremely conservative.
But you have no reality to back your opinion up? When has a 12W7 been compared to an Rl-p 15 in a fair and unbiased setup, and the 12W7 been declared the winner?
Conservative? Manufacturers aren't "conservative" with Sd ratings and one-way linear xmax ratings. As they say in one of their PDF files: Xmax specifications are derived via one-way voice coil overhang method with no correction factors applied.
Until you or someone else can explain to me with facts how the 12W7 could dominate the Rl-p 15, I'll deny it.
Aren't you just a little curious about the performance of the W7 drivers in HT? With the success of the F113 and F112 I certainly am excited to see if we could get a DIY version at a fraction of the retail cost.
I never said I wasn't, but one thing you should understand about the DIY section. We don't "make DIY versions of commercial products" we just do it better from the start without regards to what the commercial folks are doing. We can make superior stuff for less all of the time, and plenty have done so.
Also, have you not done a bit more research? JL themselves have said that the drivers in the F112 and F113 have 5mm more linear excursion than the W7s available to the public. Watch the videos on the JL website if you're curious, they go to great lengthss to point out the differences between the 112 and 113 drivers compared to the standard W7s.
On another note. I know the RL-P drivers were designed for car audio.
Who says? Even the SS website says " We are proud to bring you these stellar drivers and are certain that they will please even the most discriminating of car and home audio enthusiasts. "
Even still, it doesn't matter what a driver is "designed" for. Its either good or it isnt. The Rl-p is just basically a TC Sounds driver, and TC Sounds will tell you they don't build just Car or just Home Audio drivers. Why do you keep bringing up IASCA?
