Looking to acquire one more LMS Ultra so I can have a matching pair of 18's. I just need the driver. It il also need to be shipped to Maui Hawaii 96790. Thanks!

Hi, I built a sealed box (~100 l] for my LMS Ultra about a year ago. I recently bought 2 TC Sounds VMP 18 passive radiators and now I'm thinking my next build. Should I use both PRs for the LMS Ultra or is one sufficient? I'm planning on buying one more LMS Ultra when one is available (they...

I am building a single TC Sounds LMS ULTRA 5400 18" in a 4 cubic foot sealed box and plan on using it in my enclosed basement theater with dimensions of approximately 12’ x 19’ with 8’ ceilings. This DIY hobby has left me with quite a few subs and no logical place to put them. Is it even worth...

Looking for a used but in good condition new version (bolt on) LMS 5400! Thanks

Hey Everyone, I am going to start a sub build using a TC Sounds LMS 5400 driver and will be driving it with an EP2500 bridged but need a little help as this will be my first attempt at this. I am looking at building it similar to how the Funk 18.0 cabs are with the slightly curved sides (I...

I want to build a custom cabinet and make the most of my LMS-Ultra 5400 18"sub-woofer. Should I use passive radiators? and how big should I make the cabinet? Thanks

Hi Folks, I wondered if you could give me some advice here. I decided to build 2 x sealed enclosures for 2 LMS ultras that I brought. I used 50mm mdf to give me the least hassle building two layers and due to lack of tools/clamps etc. The boxes are around 3.5 cubic ft but (taking the...

Hi everyone. I am Bruno. I need some help to build a project around this subwoofer for my HT. Having a budget of 1500€ (around 1950$) for a new subwoofer after reading this wonderful section of the forum I thought why not DIY ... ? From what I have understood I should obtain a better result...

Just got 2 Ultra's and am planning on building 2, 6 cubic foot sealed subs. Was wondering if I could get by with 3/4" MDF for the sides, top, and bottoms (with lots of bracing) along with a 1.5" baffle thickness. Or do I need thicker panels?? Thanks!

Hi there I'm thinking of building a sealed sub - and I want to get your oppinion - for a sealed sub (I have plenty of roomgain in my 1950 cubic feet room) should I get the LMS 5400 18" or B&C 21SW152-4 21" - (5400 is 925$ and 21SW152 is only 669$)? The 18" would probably be in a 3 cubic feet...

So I'm getting ready to embark on a journey which is familiar to some and completely new to me, so I've got a lot of questions, some kinda dumb, some not so dumb. I want to lose the PSW1000 and add a Crown I-Tech 4000, either a LMS 5400 Ultra or LMS Pro 5100, and two 18" PRs. Do any of you...

Hello, Looking to build a box to be use with the TC sounds ultra 5400 18 driver. I am thinking of going with the matching PR too, but I am not 100% sure. This sub will be mainly use for music so accuracy will be very important. I have a rack amp that will put out 1300 watt @ 8ohm to drive...

Up for sale is one TC Sounds 18" LMS 5400. The original with the red frame like tested by Illka. It is the one that I took to the WI and great southern gtg's. It functions perfectly. There is one moderate sized ding in the cone from my then 4yr old boy :paddle: that's about the size of a nickel...

I just bought a used Audiopulse LMS 15" driver that's in mint condition at Ebay, at a great price. I guess I could not resist the temptation. It will be going in a 7cf birch-ply enclosure (internal) w/18" PR's that I have, tuned to 16hz and powered by ED LT1300 plate amp, (1,300watts). I...

Looking for one of these subs. 12" or 15" size. Let me know, thanks.

So I might have a chance to buy a lms 5400 and a crown k2 for around $1800 CDN. Or 2 mal-x's and 2 ep2500's for around the same price. (or wait for the new 21" mal) I already have 2 huge mach 5 IXL 18's but want to more. :) I know the 2 mal's will offer more bass after modeling but I don't know...

This project began on a Friday afternoon and was ready to use Sunday evening. You might call it a weekend project. The Driver is an LMS 5400 18" and the Amp is a Crown XTi 4000. The LMS is rated @2500 watts and the XTi is rated 1200 watts per channel @ 4 ohms, 3200 watts bridged mono @...
