Okay sorry to hit you guys up for more info again. This just seems to be one of the more helpful and informative sites around (although I read a lot of others just don't post very often). So I come to you once again for help and I do need help this time.
I don't want to come across as negative just concerned....I ordered a TC2000 15" driver. TC informed me that they are out of their cones for that model and emailed me a photo of a different cone (all flat black not aluminum) and asked if I wouldn't mind substituting. They say the parts they need to build the regular one won't be in until January or later and I could wait if I wanted to or get my money back. They say this new cone is an upgrade and won't affect the performance at all but I need someone to look at the info for me and tell me if it will affect my design or not. Here is the info from their website. They told me that it is from their 5200 line and not the 2000. If you open up the LMS driver portion of their website and click on the 5400 model it will open up a page with those drivers on it. Then if you click on the 5200 model and scroll down the page to the "competition package" you will see a picture of the black cone and this description:
Quote "The TC competition package top assembly is ideal for mobile audio users who demand more slam and higher sensitivity. This package is ideal for enclosures with higher tuning frequencies (above 30Hz). The package utilizes our ultra light weight pro audio black aluminum anodized cone with a treated composite surround, and effectively reduces the weight of the moving mass by over 50 grams thus increasing sensitivity and overall output. The lightweight surround does limit excursion to 2.5” P2P, and therefore compromises extremely deep bass; however, xmax still holds at 30mm each way. In ported enclosures tuned above 30Hz, beyond 2.5" peak to peak excurion constitutes little difference and the competition package could be used with improved output. Otherwise for home audio or deeper tuned system, the CP should not be used. The CP is highly recommended for car audio systems tuned at 32Hz or above. Because of the replaceable top assembly, The competition top assembly and standard top assembly can be swapped at any time."
Now my enclosure is a typical LLT (24" by 48" sono, 28-30 inch port (6incher)). The part that concerns me is this line ...."the CP is highly recommended for car audio systems tuned at 32Hz or above." (and this line)...." for home audio or deeper tuned system, the CP should not be used." :raped: :raped: :rubeyes: :rubeyes:
Now TC reps told me a tech said it would have no effect on my use of it. But would this cone when used in conjuction with the regular TC 2000 voice coil and basket make a difference in my ability to tune my sub to the 15 HZ range??!!
Somebody please help! I don't want to end up with a driver that will give less than satisfactory performance.
