Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Well, it seems the SMS has gone down a bit since I first saw it. either way, you need to see what is going on before you apply any boost or cut. What did you use recently to determine the boost and...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Well, look up REW on this forum and try to get it for starters. Then if you can get a Galaxy SPL meter about 129.00 at parts express, it will help immensely to start.

Wish you lived closer, I have...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Without the REW to get some kind of graph, you cannot tell what needs to be boosted or cut, again you are just going by ear. You can;t just arbitrarily select a frequency to boost or cut just...

You need to download REW and get some measurements. Also, reign in the volume control a bit and the boost or whatever is being done down low.

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Do you have any idea what kind of output you are getting at the moment? As far as decibel levels? What size room do you have. Is it sealed? With one driver, I would suspect output at listening...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

you need to post a video of this thing doing what it does when the noise occurs. I do not think it is bottoming, I think you have an issue with the amplifier. I would try each channel individually to...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

If the amp is not reaching full power and clip lights are not coming on, I would run it in stereo to see if both channels do it. Is the amp bought used? I would definitely use one channel and then...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Also, you need to use the modeling software to see what the system should do at what signal level and whether a HPF is needed. Remember, it takes twice as much power to get a 3Db increase in SPL. So,...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Advantage is you never clip the amps. You have a clean source of pure power. You have enough headroom to handle all the transients that some of the newer films sound sources have. Example- download...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

The noise on any pro amp that puts out massive power is probably more than most audiophiles can tolerate. The fan mods help a lot, but all in all, the only true way to eliminate the noise is to put...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

Yes, it appears you do. I needed a High pass filter set at 14 Hz, and I wanted to get there without using a combo of filters, so I went with a MIC 2200. It has high pass filtering from 10-200 HZ. I...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

The EQ is designed for PA setups. It is fabulous for all the tinkering you need for that.....But, no filters down really low below 20 Hz. Also, you need to have it hooked to a computer for all that...

Re: Sealed TC Sounds LMS Ultra 5400 18" NOOB STYLE!!

First off, you need to be able to "see" what is going on. That sub is "designed" to output a certain amount-right? Well, once you get there, you need to know it. Your ears and you body are a good...
