TC Sounds LMS Ultra 5400 18" DVC Subwoofer
TC Sounds LMS Ultra 5400 18" DVC Subwoofer is rated 4.75 out of 5 by 8.
Rated 5 out of 5 by from Bad Bad beast!This is one great beast! Did a ported enclosure that can reach down to 15hz... running on Behringer 6000DSP..too bad amp can only reach 20hz but is enough to shake the room! am already considering to build another duplicate of what i have now and connect to channel B of the amp...the only limitation... my wife.no regrets!

Rated 5 out of 5 by from Awesome SubIt's definitely one of the best if not the best Subwoofer I've come across. Just be prepared to buy a substantial amp to drive this bad boy. I bought the behringer ep4000. It's a great amp for the money, but you can tell this sub can handle more then what the amp can put out. That being said as it sits right now I've had figurines vibrate off their pedestals. Lol. Anything not firmly supported will vibrate like crazy ex. light bulbs, figurines, windows, the grill on the fireplace. So keep in mind all these things vibrating will cut down on the quality of what your listing to. This sub works best in a theater where there's less things to vibrate.Note* right now I have it siting in my 1000sq' family room.

Rated 5 out of 5 by from LMS Ultra 5400 18" DVC SubwooferJust bought my third LMS Ultra 5400 18" DVC Subwoofer, I have been building speaker systems for about 35 years. This sub woofer astonishes me on the ultra low frequency bass output and the quality of sound. Best woofer I have ever used in a system. These speakers are power hungry but the results or worth it.....

Rated 5 out of 5 by from Best Subwoofer for SQ/ULF I have ever owned!The title says it all.I've owned, Mal-21's, SDX-15's, Dayton PA-18's and Velodyne's over the years.The LMS-18 wins in both thermal power handling, dynamic expression and ultimate Sound Quality, thanks to it's uber-beefy magnet. Additionally it's bass-response efficiency below 20hz in boxes that are under 8 cubic feet in size is second to none.I'm flat to 6hz in my room thanks to these subs.

Rated 5 out of 5 by from Outstanding subwooferin a market filled with "louder is better", this subwoofer demonstrates that finesse and quality exists, even in the high-power 18" market. I have been designing and instaling high-powered SQ systems for 20+ years, and I can honestly say these are the finest 18" drivers I have ever used. The clarity and extension of this subwoofer is incredible, possessing resolution and detail normally only found in much smaller subwoofers. The amazing part is this sub can provide astounding levels of sound quality while acoustically kicking you in the face! I have 3 of these in a 2006 HHR demo vehicle, pushing 7,500 Wrms, and the vehicle has won several sound quality competitions, beating out everything from 10"s to 15"s in clarity and resolution. components right now consist of Selenium 6W4P midbass (3 per channel) and Tang Band 1" extended range in the A-pillars (7 per channel). The quality of these subwoofers cannot be overstated. I have the subs mounted in 5.7 ft3 (net), with 77 in2 ports, 45" long, for a 25" tuning per sub. If you are looking for stellar performance in all respects, these subs will blow you away.

Rated 5 out of 5 by from Best subwoofer I have ever tested.This is an expensive and heavy woofer. However, those are the only drawbacks regarding this beautifully engineered speaker. Looks,build quality and even the seperate packaging of magnet and cone reflects a rare attention to detail. The objective performance is unequaled in my experience. Total harmonic distortion between 20-100 Hz. is 0.4-0.7% at 110db! As output level increases, the distortion rises less than any other woofer ever tested. By comparison, the Exodus Maelstrom 18 measured no cleaner than 2.4% at only 90db and got MUCH worse as level was increased or frequency decreased. The TC Sounds sub maintains low distortion down to 8hz. Frequency response linearity is excellent even up to 1 Khz. Impulse response is exceptional,especially for an 18" sub. Objective excellence translates directly to superb subjective performance and realism. With box requirements as small as 2.6 cu.ft. sealed (f3=43 hz)and 4.3 ported (f3=24 hz) Thilo has hit a grand slam. Now, how about a sale...

TC Sounds LMS Ultra 5400 18" DVC Subwoofer

i forgot to mention that i live in australia, where the voltage is 240v...  it doesn't mention that 240v is supported by the EP4000 on this website... Do you have anything that will drive this properly at 240v?

Asked by: willba4
Unfortunately the highest powered amplifier we have available that will support a 240v input is the Dayton SPA1000.
Answered by: MattP
Date published: 2014-07-22

would the SPA1000 be a good combination with this subwoofer?   would it be able to drive it properly as a 4ohm load? if not, do you know of any other subwoofer amps which would do it justice? cheers, william

Asked by: willba4
This woofer really needs about 2-3,000 watts in order to get the most from it. I would recommend something like the Behringer EP4000 bridged which will produce about 2400 watts into a 4 ohm load.http://www.parts-express.com/behringer-ep4000-europower-power-amplifier-2-x-1400w--248-748

Good Day, Can these drivers be used in an open baffle arrangement and would a Crown XTI 6000 amp be adequate?

Asked by: Verusano
I would not recommend this driver for use in an IB application, the Resonant Engineering XXX18-V2-2 or Dayton UM18 would be a much better choice. That amplifier will be plenty for either of those options.http://www.parts-express.com/re-audio-xxx18-v2-2-18-cast-frame-dvc-subwoofer-driver-2-2-ohm--268-8154http://www.parts-express.com/dayton-audio-um18-22-18-ultimax-dvc-subwoofer-2-ohms-per-coil--295-518

I don't have much space for my install so I was thinking of inverting my LMS Ultra. Has anyone had good luck with this? Thanks...

Asked by: BrandoYo
Inverting this woofer will not be a problem.

Hi, is this a good sub?. I have a new cerwin-vega plate amp that was ment to drive a stroker 21" speaker. it is rated at 2000 watts / 4 ohms ..looks solid and well made. I have a ported , 9.0 cu foot box. how do you think this would do?

Asked by: tavegas
This is an excellent woofer, one of the longest stroke, low distortion drivers available at any price. I would not recommend using it in a ported box however, it will work best in 4-6 cubic feet sealed.

what is a magnet boot for a LMS-Ultra?

Asked by: grannie
A magnet boot is simply a rubber cover that is wrapped around the magnet of a driver for aesthetics and protection.
