A servo system on a sub is a bad compromise. Lower 2d order distortion down low (where it's perceptually unobjectionable) coupled with restricted top-end bandwidth.

So better to just use a good driver than cobble up a flawed electronic compromise.

That's pretty interesting, thanks! Wonder why Rythmik subs use them then. Or why did he (funk audio founder) say hes gonna add one to that super sub? Looking forward to your response! Trying to decide what my future sub will be.

Did you say that because of the CEA max burst tests found on audioholics? You seem confused about servo. Low second order distortion is more dependent on the motor and maybe flux modulation, no?

There are different forms of servos too. Nathan Funk stated it is not a servo since it measures the internal and external air pressure somewhere not found on the driver. If you are really curious about servo, I would start a new thread. I will say that servos main advantage is not about reducing low order harmonic distortion .

Hope the prototype with differential pressure control works out. I'll be interested in learning more about it once it progresses.

The differential pressure control is completely different system than accelerometer type servos. And in theory has none of the drawbacks of traditional servos. As far as what traditional servos can accomplish there are other ways to get the same overall results with fewer compromises. Our TSAD based subwoofers are an example of non servo design with very low distortion great accuracy and high dynamic headroom. The differential pressure control should take the TSAD to the next level without sacrificing anything. Other than cost of course.

We may be ready to accept preorders for this new subwoofer design(both the dual opposed and trisub) relatively soon. Feel free to contact us for information on getting in on a review panel prerelease order.

Hi Nathan,

I'm interested in your new design, the 15.3, but couldn't find proper infomation on the net. Can you tell some facts about it, e.g. which drivers will be used, which amp, how much will it cost, and last but not least, when will it be available? And what's especially important for me: Will it also be available in a 220V-Version for international customers (I'm from Germany, so this is an important fact). Thanks for your efforts and sorry if I overlooked any information on this in this thread.
post #246 of 703
The 15.3 is available to order now, we just dont have the product page ready yet.

It will use the same driver and passive radiators as it did, but the standard will now be with an 800 watt Class D DSP amplifier. It will be $1850 shipped in the USA It is 220V compatable, shipping to Germany will cost more, feel free to contact us for a quote.
post #247 of 703
Ok, thanks a lot for these informations, I'll have a look and probably contact you!

Can anyone guess what pair of subwoofers can do this at 14hz, in a 7000+ cubic foot room, 9 feet away. That is 2.8% second order distortion for anyone who does not feel like doing the calculation.

Dual Bose Acoustimass 10 Series IV modules colocated? That's what I assume from the advertising anyhow.
post #251 of 703
Fyi, not colocated.

And no not Bose.

Here is the FR

Something using the W2-1625SA drivers perhaps?
post #253 of 703
i know, but i'm not telling. :-)
post #254 of 703
Two eighteens. I also know, but I gotta have fun to!
post #255 of 703
Perhaps one of you could spill the beans then, because it appears Nathan has gone silent on the matter.
post #256 of 703
He's just busy. There are a few very interesting things coming down the pipe. To make the guesses little easier it is completely a Funk Audio product.

The new 18" sub driver you have been working on?

Nah!

But it is two 18's.

I'm here to goad you guys along, not give away the answers!

A furry monster?

They are veneered.

How about multiple choice?
post #264 of 703
What do I win if I guess correctly?

Awe nuts I'm on the inside, I canna win anything!

Multiple choice eh?


TSAD 18

Faital Pro 18

LMS 18

Choose yer poison.
post #265 of 703
Hi Nathan,

I guess a pair of my 18.3 porbably with the TSAD 18" with upgraded motor structure is able to achieve this.

So close, I will now say; It is a pair of standard 18.3's, with TSAD18v1, A2.4kw M2 amp, and HSAD18v1 passives.

So exactly my subwoofer - but twice of them. I wonder what the TSAD driver with upgraded motor structure can do in the 18.3 design? about your upcoming dual sealed design - is it wise to combine passive radiator subs with sealed ones in the same setup? I guess the different phase shifts (due to rolloff and internal EQ) don't make this combination a good option.

Cool, how much would all that cost? thanks

Thanks, very impressive. I'm guessing the output would be similar to a JTR Sealed Cap 2?
