8x 18" LMS Ultra 5400s in 4 sealed enclosures - Page 9

Would he not need one per amp?? Each amp requires 20 AMP circuit alone, no??

Nice price though, Im buying one for my main speaker amps, AVR, MiniDSPs.

Thanks Scott! I think we've talked about 'em in the past. I got a smokin deal on them straight from Polk years ago. I'm hesitant to replace them, but all these JBL builds look damn tempting!

This is probably the most impressive subwoofer build I've ever seen!

Agreed, I love this build and your lucky NotNyt to have such a great room for all that you have. I'm very jealous.

Ever since TC-Sounds regrouped so many possibilities opened up, at least for me they did.

I never thought I would have woofer envy with 2 LMS 18's, you guys are brutal

don't forget about chuck and his lms passive radiator monster with the crown itech's.

He brought in like three 220 lines to power the itechs from what I remember, may have been four.

I use stainless wire (it's actually safety wire for racing) strung through two holes on one side of the basket, and two on the other, makes a "handle" on each side. Then I use heavy leather gloves so the wire doesn't cut into my hand. Once the driver is set in place the wire is slippery enough you can just pull it out and you are set to go.

I super glue the rubber gasket to the bottom side of the frame, you can then use the rubber as a handle... works awesome...

Whoa - Thanks....
My room is always open in the daylight and I prefer it to have nice looking wood fixtures out in the open like furniture, if I was doing a basement build it would be a whole lot different - much like your setup... Only when its dark out does all the stuff in my room just fade away... Jealousy comes in the part from that full on sexy wall of goodness is seriously intimidating looking !!!! Scares the $hit out of people before they even hear it.... HAHA

"Would he not need one per amp?? Each amp requires 20 AMP circuit alone, no??"

i was thinking that it could be used to generate the signal that would then be detected by a current sensing switched outlet on each circuit.

healthnut purchased 18 lms drivers iirc. the build used eight. what happened to the other ten?

really amazing build. I am new to this DIY. I am starting with a single LMS in a 22x22x18 box. Curious what gauge speaker wire for internal/external wiring. Also, for good contact with both the 2 ohm coils and the speakon connector chassis did you solder the contacts. Did you use the standard 2 pole or 4pole neutrik speakon chassis. I bought the 4 pole as it is designed in a circular fashion to better attached to back of cabinet.

what are you running with the marathons 20A or 30A each amp or what?
I am considering the marathons 5050,4050, QSC RMX5050,4050, crest pro8200, cc4000, crown xti6000, xls5000. I am going to rewire a couple outlets for a better supply of juice. That way I will have room to expand in future. Room is @2250cuft. 21.5'x11.5'x9'

could not find warranty info on marathons website, is it stated in there product manual, could get the 4050 or 5050 for @ 1/2 the price of the QSC's - 6yr. warr. thanks

He sold the other 10.

WOW....WOW!!!!

i would be scared to be in that room.

btw, how do you guys run 4-6 subs? i mean most AVR has only 1 sub output?

this raises an interesting question, what does a simple splitter change if anything?

is that worse than using the output from the amp to "daisy chain" them together?

is this any different than if i run 1:2 rca splitter, or 1:4 splitter if i want to run 4 subs?

If you are running 4 subs then buy a DCX or the MiniDSP. Connect the AVR to the DCX or Minidsp then allow either of the DSPs to handle your 4 subs. Independant EQing, phase, delay controls are important to have when setting up a sub system.

does everyone using the LMS 5400 use some type of HP filter or not (is it needed since this driver can go low) either thru there amp or thru their DSP if possible

Good lord, man. Epic SPL and extension.
