"Curious....Why do bigger drivers excel at low frequencies as opposed to using the same amount of Vd in multiple smaller drivers?(LTD)

It would appear that in simulations there might be a very small advantage but when listing we tend to like the big drivers better. I know many that have said they love the FTW21's over other 18s for ULF. Then the SI 24 comes out and people are all saying the same thing."


if i had to take guess, it is probably because most folks just hook them up and play some tunes, make a comparison, and draw a conclusion.


the larger drivers have more sensitivity because they couple to air better and lower fs because they tend to have high mms (coil, cone, air load), together that gives them a different frequency response and subjectively 'more bass'. this then leads to comments like 'wow, driver really digs deep'. then by reverse logic, some folks might then look at the specs and conclude that the specs aren't telling the whole story because they aren't correlating to what was heard.


this is the problem that james (mk) was referring to, as he may have at a point long ago found himself in a similar situation.

Listen. It's All Good.

looks like ronal murphy builds the same sub by hand right here in america too using parts of his very own creation!

Did some reading on this. Seems like there are at least 3 mfgs who have used this basket/cone assembly, which is Chinese-built.

It's all catalog parts. Nothing of their own design except maybe the motor. No need for custom parts if they are readily available from a OEM.
I'd bet there are for more than 3 using the exact same parts. If it's one of the only baskets, cones and spiders available for HT 24's, you'd bet their are custom guys/companys making them all over.

Literally took 15 seconds to pull up a 24" basket on alibaba....

Beware, now everyone will be building them in their garage...

They have been there on that site for well over a year now. Someone asked before about building them and never did. SO I doubt anyone will be taking the challenge anytime soon. BUT there are a few car audio guys taking the plunge. Dont know why but what ever works.

If the concern is for a third party to test this driver why not just send the driver to Vance Dickason at Voice Coil Magazine and have him run the tests. He does this type of testing for more than 30 years. He also has a great deal of experience in system design and could offer some insight on this driver.

Looked into it already, there will be someone else coming out with a 24" fall/winter thats not Mark, Not 100% sure if it's coming to NA but I'd bet it will, shooting for 7CF enclosures as optimal. Big company, so expect the price to be under 800$. Other than that, I don't know any parameters but I have seen pics of the prototype and it hammering

Mark said he could help anyone interested get a batch of parts for under $600 to build them themselves but has no plans to offer them as of now. he's got other things in the cooker at the monent

Saying "nothing of their own design except maybe the motor" is pretty vague and ostentatious. A quick look at the parameters on Tantic's site will reveal a toally different driver than our HS 24. We utilize a totally different motor, coil, and spider than the Tantric unit. Is their unit possibly louder at 65 Hz? Mabye. Is our driver louder and peform better over the entire bandwidth of a subwoofer? Yes. And all of our parts are custom tooled (motor, coil, spider, adapter - both hard and soft - etc)- no "nothing of their own design" like you stated. If you want to come out with your own 24" woofer I welcome you to the stage. After all, nothing is custom tooled according to you.

Your quoted comment is like saying that every vehicle that shares a similar wheel base is the same thing without looking at every other performance detail. Not every 12" woofer is the same. Not every 15" woofer is the same. Etc. Just because the size of the diaphragm is the same does not mean the performance is the same.

Was he referring to SI having nothing custom of Tantric? I could be wrong, but read it as the latter. Also, where on their site do you see T/S parameters?

Nick, would you recommend the 24 be used in a professional setting with compressed EDM for 4-8 hours with 1500W of power? Should it fail will it be covered by the warranty?

Where did I say everything was the same? I said they are off the shelf parts, which means, parts I can buy myself, I didn't say anything about the tantric driver either.
Other than rolling your own adapter and coils, I'd bet I could get everything....

You mean, you know people in the industry that could get you almost everything? I know people too.

I bet I could get EVERYTHING... Including the adapter and coils!

I might even have a hook up to help me assemble everything.

Scott, what do I win?

Nick, So with the new motor was the design for lower Le and higher Bl or what were the new design goals with the XBL2 motor?

xbl^2 is a split gap technology that allows for a larger region across which the bl is flat.


it usually results in a little less bl at the rest position vs. a simple overhung design, but holds its bl better further out.


wow. the paper is still available online:

He had shown in past videos or photos that he had some custom motors made for the 24 to possibly use in the future. So I guess he finally built one to show us.

Don't forget how low that bad boy goes...dang...all the way down to 30Hz. I wonder if it has enough excursion to handle that.

Not sure what your saying?

And you dont need to go below 30hz because nobody needs it. Anything below that is a waste.

And LTD I was only thinking why just add a different motor if you were only trying to one feature was all. BUT in saying that an OEM might have wanted it done also. I am always reading about Jacobs new 18's and how some of the designs have crazy low Le figures. So when hearing about a new motor I though maybe there were a few things they were trying to improve on.

I always think its funny when I see a 30min order of these types of speakers. That is crazy but then I think of this forum and remember that would only take one forum member or possibly 2.
