wanna see why TC sounds doesnt use aluminum cones anymore???

ew this makes me not want to get a TC-3k

I know that titanium is stronger, I was just stating something. An to me the ti cone had a different sound than the aluminum cone that i didnt like.

Ah, that is a disadvantage of a metal cone, it can "ring", ie. vibrate at a seperate frequency unintentionally due to the fact that metal is very acoustically alive. Paper is in some ways a better choice as it has better dampening characteristics. They all have their disadvantages and advantages though.

why... the 3hp is an excellent driver, besides they havent used these cones in a very long time

it was a great driver, got real low. Jus wasnt a big fan of either the aluminum or ti cone.

LMS is ear *** //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif

ive never dealt with a split coil design but i do understand how it works
but to me its a Toss up between LMS and Xbl^2, imo LMS will prolly sound best but has the most drawbacks (amount of power it takes to get the sub moving, box requirements, etc...)

Also LMS is a HUGE coil and large gap increasing Le and also decreasing BL, but they handle a lot of power and from what I have heard are slightly more linear than XBL^2 drivers. XBL^2 generally has lower power handling and a smaller gap which can cause problems if there is any coil rock. IMO split coil is the coolest tech, but also the hardest to implement and uses a lot of power, lol.

Anyway, definitely take pics of the LMS coils, I want to see some of them out of the driver.

this is one of the 3" lms coils... its not that big

and BL decrease and Le increase create the huge box requirements i was speaking of

I had an original 15" TC 3K and never had any issues with it...even ran it free air to the point where it was almost slapping the VC former against the back plate.

3hp's are great subs... ive used quite a few of them

this is the first time ive ran across this problem with an aluminum cone

Old video, but lets take a look at it for the fun of this thread.

ps. this is really old news...but fun to watch.

 

[dcole18 5,000+ posts]

i dont even need to watch that vid to know what it is... lol

ive said this tons of times, i have no problems with TC, i stll use their products and prolly always will

this thread wasnt intended to bash TC, i was trying to show ppl why they made the change to Ti cones

For low to moderate power levels, the aluminum cone will hold up just fine. When combined with an LMS coil, its one of the most accurate subs, imo.

Even the 3" coil is generally going to be wound thicker than a regular coil, that is what I meant, not the fact that most use a 4" coil. But yea, the BL and Le is not a horrible trade off if you have the space for the drivers as they perform amazingly.

I prefer the Ti considering most LMS coils wont be used at Low, moderate power levels //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

It's not just your opinion, it's basically an accepted fact //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif
