Was considering that with a 40cuft or so sized box and basically just use it as my rear "bar" from now on, but just didn't have the time or wood to build that out before the g2g. I may still do it one day, but that is just a LOT more wood and I am not even positive if placement is good where my bar area currently is, out in the middle of the room.

Yeah that would be a bitch to build and move. Definitely be the ultimate LLT though!

My Dual 18" LLT subs 120dB down to 10hz

I'll volunteer to build you a cab for the next GTG.. 50 cubes Ported at 10hz. I just don't have a driver

The effort of building would be worth experiencing that awesomeness. That thing should have more output capability at 10hz than 20 sealed LMS ultras.

Buy 3 sheets of 4x8 wood, cut them all in half. Boom 4x4x4 cube. and about 60 cubic feet before ports. Use sonotubes as ports

It would only weigh like 300 lbs..

Good placement options there huh? Oh, and you would want to double all walls, 1.5" thick, trust me. I braced the crap out of the sealed box and that thing was still moving around judiciously, with a 125 lb center channel on top.

SO then 4x4x4 with double thick MDF. Yup that should do it. With excessive bracing. If you high passed at port tune, and cut a few db above and below port tune, but then boosted port tune like 6db to make it a one note wonder... I wonder what kind of SPL you could get at port tune ?

I'm pretty sure it would set the record for a 10hz sine wave. call it the "pants flapper"

Probably would fold the horn on a full 8x4 sheet, might even need a custom 4x12 sheet ! Folded horns leak if you span sheets.

It always make me laugh when you look back after a few days and your sub danced it way into the middle of the room
I built a little 1.5cuft cube for a 12" sealed TC-3000 double baffled and braced. My friend uses it with about 100 lb of weight on it. All it takes is Bass I love you and it slides like its on ice bahah.

A giant horn with the SI 24", Submaximus V2.0

It would be way beyond submaximus, the submaximus didn't perform up to expectation. We'd need to call it something like "EBM" Excessive bass module.

Excessive Maximus has a nice ring to it though.... That thing at tune with some boost would be a like a supernova explosion.

Yeah, double MDF that's like 600 lbs + driver + bracing

I liked the name "home wrecker" haha. that's great!

Seriously though... someone needs to fold a horn for one of these suckers. I'll build it. Just because it's excessive. I am not afraid.

dbkicker I think had it. He built the horn out in his garage that backed up to the listening space and had the mouth open into the corner of the room. It was massive, but I don't know if he ever actually got it fully functional or not... Funny thing is, I could do the same sort of thing for my casual tv den area, but would basically have to remove my entire storage rack in the garage where I keep basically all of my woodworking and outdoor landscaping stuff. Can't validate this move at this point in time...

I'm thinking about adding a HS24 to my current 3 LMS 5400s (in purple). I modeled a few enclosures and was looking for thoughts.

With all of the talk about ported enclosures, I modeled one but had to bring the power way down from 4000w to 1000w to keep the sub within excursion limits. With the difficulty of integrating a ported sub with a bunch of sealed subs, I'm leaning towards the sealed enclosures. I'll be building the enclosure into the wall next to a fireplace insert (similar to this picture http://www.doityourself.com/forum/at...s-air-bump.jpg). Thoughts on the different enclosures for the HS24?

I dont know why but that graph doesnt look very impressive. I am sure it is fine but I have a certain image in my head on what the 24" can do is all. Why not port your 5400's like Not?

And is the fireplace in a decent spot or in a known room mode?

I know what you mean by the graph not looking as impressive as expected but I was at Beasts GTG and the HS24 is a very potent sub. The fireplace bump out is on the left side of the room. Two of the LMS 5400s are at the front flanking the center and the third is in an end table at the back right of the room. This is in a living room and I don't have the space to port my LMS 5400s.

cut the box size in half, tune to 15hz, feed more power. It will be a good deal more impressive.

Or just throw the LMS into ported boxes =]

Sorry about your experience. WOW

Dgage when I simulated your Ultras it would appear at 25hz you will destroy your woofers in 5cuft each with 4000watts each. Or maybe I have some old parameters. Not have you had a look?



1900watts for the 70cuft 11hz tune
3000watts for the 35cuft 15hz tune
12000watts for the sealed 5cuft. Sealed has a 15hz Hpass also.

(3) LMS = $3000

(1) 24" = $999

Model three 24" and check it out.

Not quite, more like


LMS-U $925.87ea X3 = $2777.61 free shipping


SI 24 $999ea X3 = $2997.00 plus shipping, and its probably $100 per driver to ship.

Its also a matter of how much space someone has. The wood it costs to build the enclosures and whatnot. Lets just stick with the 1600 price tag and say you can get roughly a pair of 24's for the price of 3 Ultras. I am not going to be able to buy them when they are on sale. And for me the price is about 2200aud including shipping for just one.

While some have room for 24's others only have room for 15's.
