Dissapointed in TC-1000

cancellation.

try the box in another position in the vehicle..

Alright, So the box is all sealed up now.. That didnt really make a difference...

Here is what i did find out though.. My windows..

With my windows up, the output from the Tc-1000 is pretty much the same as the stock factory sub that came with my truck..

However, when i roll the windows down, the output greatly increases.. And it has the output that i would expect from this sub.. (nothing like my last setup of 2 12" TC9's) but respectable for a single 10" sub.

I also tried the sub in different positions.. Turning the down upside down inorder to make it down firing and turning it so the fires backward, did make a every so slight increase in output, but barely audible, so i don't think its worth redesigning a new box.

Anyone know anything about the windows.. Any way i can get that same output with the windows up?

The windows thing is something that you cant really avoid, just a phenomenon that occurs with all systems, varying from vehicle to vehicle..

One thing I would suggest is moving the sub to the back and stuffing it with some acoustic fill...

 

[bushtree 10+ year member]

Yea i know it happens with all systems.. Just like all my previous setups.. But with this sub, its pretty much Zero with windows up and 100% with them down...

i'd be happy with something like 70% windows up, 100% windows down

I got a video of the TC's moving.. Lots of excursion..

Assuming everything is set up correctly and your amplifier is able to give ~500 watts, and coils are in phase, the TC-1000 is still going to need some EQ relative to higher Qts drivers which will naturally ring (AKA: boomy bass) more and provide more SPL around ~30-50Hz without EQ. The TC7 works very well in sealed box for this reason, but the TC-1000 or any of our other drivers will need some EQ because they have very damping from large motors. In some cases, especially when you don't have the capability of tuning a system with measurement or modeling equipment, a lower BL driver can actually outperform drivers with larger motors if they are not EQ'ed with proper voltage. If you are unable to make any improvement, please call or email us or shoot us a message on our tech support forum and we can assist you one on one. Rolling your windows down turns your car into a 4th order band pass system.

I just installed 2 TC-1000s yesterday and have 400 w rms going to each and they sound great. I have them in 1.25 cubes each sealed. They are 12" though.

12" works a lot better without EQ in a sealed box, 10" is harder, 8" forget it, you should port the 8, or have about 10+dB boost at ~25Hz. I have heard a number stories about the 8's making no bass in sealed boxes, the motor is actually "too" large for that driver and we will most likely downsize to the TC2 in the future so its easier to use.

What kind of EQ'ing are we talking here?? Are you saying i should use the bass boost, with this sealed 10" ?

Im using a PG Xenon 400.1, which produced 421watts..

TC Please help //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif I've ran your TC9 motors in the past and absolutely loved them..... Just cant get this TC-1000 to do what i've heard its capable of..

Yes, bass boost for a sealed box. How does the subwoofer sound in the rear? The driver could also be in a node (standing wave at some frequency that is critical), but that is less likely I think.

How must boost? Well honestly, if you want the most SPL at low frequencies in a sealed box, as much as you can before it bottoms out or clips the amp. Shoot for 30Hz, maybe even 35Hz, it will be easier to get more bass there than with lower frequencies.

Sure thing..
Im thinking there has to be something wrong, as the TC-1000 is about on par with the stock factory 8" sub that came in my truck... I dont expect it to have output like my last setup of 2 12" TC9's but hell this is just plain weak.. //content.invisioncic.com/y282845/emoticons/frown.gif.a3531fa0534503350665a1e957861287.gif

How big of an impact would a leaking box cause? That is the next thing im going to check.. There is a possibility of a small air leak.

Thanks for the help so far //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif

It sounds the same when sitting in the rear seats as the front seats.. (Its in a truck, not the trunk of a car..

Tomorrow i'll try tweaking the settings and using some bass boost.... I've just always never used any boost and just feed the subs lots of clean power in the past.

its a 1k for crying out loud. what do you expect?

so bass boost is needed for that woofer? //content.invisioncic.com/y282845/emoticons/laugh.gif.48439b2acf2cfca21620f01e7f77d1e4.gif

Bass boost is a loose term... it's called setting the EQ //content.invisioncic.com/y282845/emoticons/smile.gif.1ebc41e1811405b213edfc4622c41e27.gif "Boost" isn't being used to make a peak, it is being used to flatten response.

The sub has a low Q so has low output on very low bass sealed, therefore you boost the low frequencies to flatten the response since the sub has plenty of excursion to handle that and you are good to go. Alot of high-end home audio sub systems use a similar method to get their low-end output.
