My TC Sounds LMS-R Ultra 5400 18" sub is almost as loud as a ported HS-24 mkIII 24"

I used WinISD to measure my TC Sounds 18" vs the HS-24 mkIII 24" subwoofer both in ported boxes. I used to have my 18" in a sealed box but changed to a ported box tuned at 20hz and it gave way more SPL and still sounds as good as the sealed did. My box is 7ft3 after all displacements. And the 24" went in an 18ft3 ported box tuned at 18.5hz almost 3 times the cubic ft. of mine. With 2000watt RMS to each At 20hz the 24" did 122db. The 18" did 118db. At 30hz the 24" did 124db. The 18" did 120db. At 40hz the 24" did 124.5db. The 18" did 121db. And finally at 60hz the 24" did 124.5db and the 18" did 121.5db. I dont think roughly 3 to 4 extra db of SPL is worth a box almost 3 times the size as mine and the subwoofer costs $1,275. I got my sub for $900 and a box made out of 1" MDF that weighs 150 pounds without the sub in it for $500 and the Crown XLS2500 amp for $650. I was considering the 24" SI sub but definitely changed my mind after that comparison.
Here are the 24" T/S parameters:

Here are the 18" T/S parameters:

What do you guys think about this comparison?

My 18" sub is not the only bass driver I have. I have 4 of these 12" Mid Bass Modules:

https://www.diysoundgroup.com/home-t...-12lx-kit.html

They handle 40hz to 80hz and really hit the midbass hard!

This is the flat pack I used for the 12" Mid Bass Modules:

https://www.diysoundgroup.com/home-t...flat-pack.html

The new ones come with 1 port not 2.

I dont have a 24". But 4db is not twice as loud! 4db wouldn't be a ton more noticeable.

Wait, what? You just compared a 24” to an 18” sub.

For every 6db it’s perceived as twice as loud. He’s right and also knows his crap about subs.

The LMS 5400 is a great sub, but no longer available. If you have them, keep them, or sell them to BtH. 4dB is significant, maybe not with 3x the enclosure volume though... but still, LMS is unavailable.

UM18 would “only” be 2-3db below the LMS at 20hz for a third of the cost.

We could probably keep chopping off another 2-3db until we reach the conclusion that the only reasonable purchase would be a buyout 4 incher.

We should also stop comparing the LMS using its old price. That driver would cost more in today’s market. Probably should have cost a little more back then too. Maybe they would have stuck around. The Neo Ultra 18 would have been nice.

Do you guys agree that 4db is not that much considering that its a 24" sub with a grossly enormous box? You're right the TC Sounds would cost probably $1,250 as well today. The TC Sounds is the most efficient and linear sub ever made! I wish I had another one! My 4 12"er MBMs are louder than my 18" for most songs but not songs with bass below 30hz. The MBM's are great for what they can do! The UM18 probably couldn't keep up as well around 30 and 40hz as the TC Sounds 18". The reason I tuned at 20hz is because I think anything below that is only felt not heard and puts too much strain on the subwoofer for the little bit of bass you only feel. If you do a WinISD or BassBox pro make sure you make the ported box for the TC Sounds 7ft3 tuned at 20hz.

Same power, generally same excursion, double cone area. Yeah, 4db sounds about right. Yeah, the box is huge, just the characteristic if that particular sub. Not much competition in the 24” arena.

LMS most efficient? Nah, I’m sure the $90 pa460 will kill it on efficiency for both price and input power.

Not to say the LMS isn’t a great sub, but as the most expensive 18” HT driver produced, it had better be.

IMO, a more fair comparison would be to continue throwing power at them and find the limits of both, databass style. I seem to remember the LMS being susceptible to mechanical damage though, so probably not a good idea.

Most efficient when it comes to an 18" that handles 2000watts RMS. That thing is junk compared to the TC Sounds. You could use it as a frisbee! That sub would sound like crap compared to a sub that was considered the best sub in the world at one point.

BTW I never listen to my 18" louder than my Crown can run without the light turning red which means the amp is clipping so it will never blow!

My 10"er woofers on my 1099's from the DIY Sound Group have bigger magnets than the PA 460s. And the 1099s have 99db sensitivity but also sound great doing it! They can keep up with my 18"er and 4 12"ers at super high volume and sound better than the 700 series Bowers and Wilkins speakers in my opinion and my wifes opinion without being biased at all. The 800 series did sound better than my 1099s though. But they were $22,000 speakers.

I dunno, set up $1000 worth of pa460’s and feed them 2000w and they will probably win on both output and low distortion. Box volume and size will be ridiculous of course.

As for an 18” that will take 2000w, I’d bet one of my mini devastators loaded with b&c 18ds115 would take the LMS from probably 30hz up. The LMS will win down low due to xmax.

There are plenty of good woofer options, so while I’m glad you’re so happy with your LMS, I’m not sure where you’re going with this. I doubt you’ll get many people to agree on any specific sub being the “best”, especially one that is no longer made and was out of most people’s price range.

SPL is objectively measurable; loudness is a subjective experience.

I believe the rule of thumb is that it takes 10dB difference to sound perceptually twice as loud.

Sounds about right to me; I know turning up the volume 4dB sure doesn't.

Actually it's not too far off the constraints imposed by Hoffman's Iron Law; 4db is 2.5X the sound power, vs. 3X box volume difference.

So, I just reread the first post and realized this is all based off of winisd models.
Model a couple more 18’s that can take 2000w in the same box and I bet it will look very similar. SI HST-18 and FI HT-3 come to mind.
You could try a few high displacement pro woofers as well, say BMS 18n862 and B&C 18ds115. Those should at least look a bit different.

Lol, quite a few people around here run pa460’s and love them. They are supposedly wonderful drivers for $90. I will find out soon enough, I’m putting one in a spare cabinet as a music sub for my shop. I don’t expect it to compare to my 18ds’, or my HST’s and NSW’s once i get them built. But for cost effectiveness, it may beat all of them.

Remember this about calling 4db similar:
Adding a second LMS and another 2000w amp colocated with your current one would gain 6db.
Adding a second LMS and amp elsewhere in the room (not colocated) should gain you 3db. (Actual results usually vary between 3db and 6db, room interactions are strange)

If you want to see a LMS beat the HS-24, model one in a submaximus V3. I believe that cab was designed for the LMS and UXL, so it should work well. Of course the cab is larger than the ported HS. You’ll need hornresp to model that one.

Evidently, you've never been to a drag race...or my living room. The part you feel enhances the part you hear. I think most posters in the DIY Speakers and Subs thread would agree that under 20 Hz is quite enjoyable. Different strokes for different folks.

I just think the lower bass puts too much stress on the subwoofer to make it worthwhile and ruins the higher frequencies. Although my 4 MBM's would take care of the higher frequencies. But regardless I do not want to blow this 18" because I will never find one again!

Ya know what a77cj7? I have a 4ft3 sealed box I had my TC Sounds in. I will buy a PA460 and put it in there and give you my honest opinion at some point.

Lol, if you want to waste your money go ahead. Like most pro woofers, they don’t look good in sealed boxes.
I guess BTH runs his sealed, but he also runs 16 of them with copious eq.
Now if you don’t plan to use the box elsewhere, throw a port in and you’ll have a nice mbm. Should easily keep up with a pair of your 12” mbm’s.
Thats the only reason I’m picking one up, to make use of a mbm that used to hold my 18ds.

Running low doesn’t hurt the upper frequencies. It will stress the woofer since you’re using every bit of displacement it can produce though. As happy as you are, I wouldn’t change anything. As you say, it would be very hard to find another one.

If you do feel like adding the super low stuff for cheap, check out BOSS. Its another design around ultra cheap drivers though.

89.7 dB 1W/1m is mediocre for an 18.

Note that efficiency does not refer to the lowest freq, where it's largely determined by box volume.

I don't want to buy a Boss sub those are found at wal mart. I wont buy the PA 460 if you say it will be a waste of money. I dont know if that 18" would be as loud as 2 of my 12" MBMs. These things overpower my 18" and they get loud. Sorry I meant with 2,000 watts being pushed through my 18" will make it the most efficient.

4 PA-460's in ported cabs will be enough to send most normal people out of the room..

and not the Boss sub he was talking about.

A PA460 will also overpower your 18 at higher frequencies. Its a highly efficient woofer just like your MBM’s, just larger.
I think putting one sealed is a waste of money, but some people have been happy running them that way. A ported box is where they shine though. Try some winisd models.
If you need an additional sub, its a great purchase. If you don’t, its a waste of money.

Needing 2000w actually makes it somewhat inefficient. There are some of the pro designs, like the 18ds I mentioned l, that are significantly more efficient AND will take 2000w.

I have my Crown XLS2500 amp for my 18" plugged into an outlet with its own breaker. But I heard that even on its own breaker the amp wont be able to push 2500 watts to my 18" because you can only get like 1,600 watts out of a single breaker. Is this true?

It will burst the full 2500w, but can’t sustain it long term.

The spacing of the equal loudness contours is much closer in the bass region.

Sources/processing: stack of stuff that if it isn't vintage now, it will be soon!
Amps: stacks and stacks of old iron

Depends, what amp/voltage is the breaker set to and what is the power supply capable of drawing on the 2500?

A breaker is capable of drawing significantly more power than its rated for for a very small amount of time, your amp will also store power to give burst power.

Realistically I would expect a 15amp/110 breaker to last long on 1450watts continuously.
