I found the DTS:X track on the 4k Fallen Kingdom to be superior to the DTS:X track on 4k Jurassic World. Am running 25dB of low shelf at 20Hz for BEQ (optimum woukd be 18Hz)

This! I might have been the same age or just a tad younger, watched it on HBO while my parents were out to dinner. They got home and I had plans for a sleep over with a few friends up the block. The quickest way there was through our backyard to a large wooded area (Long Island) and catty-corner over to the meetup house's backyard. I grabbed my stuff, walked across the yard and up to the trail leading into the woods.....chickened out and went back out front and RAN up the street and around the corner.

I'm pretty sure we weren't the only ones who had second thoughts about walking through the woods after that flick 🤭

I believe the still in development supersub (powerful Neo driver with two passive radiators to deliver close to v3601 performance in a v1801 size) uses a Fi design - unsure if that will make it from prototype to production.

Edit: always good to have more US built drivers to compete with the Kentucky built Eminence that PSA uses.

Quick question for you guys about calibrating the sub using an SPL meter. The Onkyo doesn't really work well to calibrate the sub as it puts the sub trim at +3 really no matter where the sub gain dial is. It has no issue calibrating the speakers to 75db. I've discovered that "82" for the volume on the absolute scale is 0 db. I read that the sub channel should be 10db higher than the other speakers. So, when the volume is at 82, would the sub level also be at 75db to be considered reference, or should this be at 85db? Hope this question makes sense...thanks!

Hi,

All AVR's will do an internal recalculation to add 10db to the LFE channel, so that is not something that you have to do manually.

Mike

Appreciate it Kirkobangz!

The S1510 is really a good value. 15 inch, 960 watts, Proprietary DSP frontend which shapes the entire operating signature, made in the USA, compact size(for a 15). I can go back and look at every one of the product designs I've ever been involved with and point out things I could have done better in hindsight. Not so much with the S1500/S1510.

I don't believe the tuning point would be any lower. Basically you would have a V3611 performance wise in a much smaller enclosure and it would prolly cost another 8-1000.00 over what a V3611 retails for. Passive radiators cost substantially more then extra MDF to make the enclosure larger and use a slot port.

Scott's one of the good ones. I still remember him shipping me 24 drivers at a time back in 1999(?) when I was hand building every svs product by myself in my garage.

I've become jaded though. I suppose out of necessity. I remember being able to look at a new cool driver and only thinking of it's performance. That was it. Such a simple time..

Now, I look at a handful of T/S, I can pretty much do a sim in my head from that. Ok, looks promising. But NOW...now comes the important considerations.

* Where are they made(assembled)?
* What is the MOQ?
* What do I need to focus on in terms of potential longevity concerns?
* What's going on that could cause any assembly/QC tolerances to become a potential problem?
* What's the lead time for a PO?
* Where is *every single component* going to be sourced? It doesn't matter if 99% of it is USA sourced with a week lead time. If there's ONE component that comes from china with say 16 week lead time.....then we can have major, major logistic problems.

And speaking only in generalities how do we think we get these super duper drivers are cheap(relatively) pricing? The OEM shops everything around. 20 different factories in china can provide the cone+surround assembly? Ok, great. Who's the cheapest? Unfortunately THAT leads to a increased chance of missed shipments along with poor quality between batches.

Again, none of the above is specific to Scott/Fi...just thinking out loud(when I see any new driver).

* What's the OEM production capabilities? Cool, we introduce ONE new product with these super18 and we only need 25 a month. Yawn. But within a couple months we've come up with a new design that uses the same driver...and TWO of them. AND the original product is becoming much more popular too. Now, suddenly, we go from 25/month to 50/month then to 100/month all within a short period(industry speaking---say one year). Can the OEM scale up or will they begin missing lead times?



Anyway, I could keep going on and on but Mondays are always crazy in the office.

What Scott really needs to do is skip a step and go straight into completed system designs. Fi home audio speakers and subwoofers. He might even be able to bring cabinets in house if he wanted to invest 100k into that. The amplifiers could be somewhat of a headache. There's a lot of domino stuff going on behind the scenes right now. Every day I'm more thankful we have all amplifier design and assembly in house now Maybe we could even be the amp OEM for scott? Stranger things have happened.

No, we (I) still would want it. I guess in my head I’m thinking about the “signature “ psa ported sub with a higher price tag, but badass driver and lower tuning with the PR design. Smaller and easier to manage in living rooms that the v3601 and downright mean subterranean bass

The most polarizing movie about the woods has the be Blair Witch. Have you ever BEEN lost in the woods? Walking around for hours with no idea where you are? Hopelessly watching as dusk approaches. Seeing glimpses of dark shapes lurking in the distance? Yeah? Then Blair Witch can put a chill in your spine that's hard to explain.

No, never been lost in the woods? Go back to sipping your fruity drink at the country club...and stay out of the woods...

Lost in the woods in Ohio? Yes I have. My only concern was getting my eyes poked out by branches while walking in the dark. A small fire and tree to lean on were all I needed.



Lost in the mountains of California? Yes. My concerns were numerous and most centered around mountain lions, bears, freezing to death, and dehydration. Each of those concerns flip-flopped their order of priority depending on where my mind was at the time.


I worry about bad people very little in the mountains. "That's not a knife... That's a knife" with a thick Australian accent plays in my head. It's the animals that eat other big animals that worry me.


I was a young teen when I watched "Humongous". Corn fields still terrify me in the dark.


edit: Just to clarify, I've never been "lost". There's been times I had no idea where I was for hours or how to get home, but never lost.

Well, we got one..

49 more to go.

Be fun to try a kick starter for something like this. There was apretty big audio company that did a kick starter or something similar for a new subwoofer a few years ago. Here it is.

https://www.ecoustics.com/news/artis...r-kickstarter/

For us, the amp is easy now. The cabinets...meh...as long as we had a a fair number pre ordered that's not a big deal. The driver and PRs are the big tickets costs. Then once the cabinet is done we can also consider a low power version of course.

One thing I've gone back and forth with on this is the grills. None? one(active woofer)? three?

Sure. But then he got in the ring and gave them a chance.

As you said, you already have one. Make another one, and I will drive the 12 hour round-trip to pick them up to save you from having to find a way to box and ship them. I also do not need grills.

I’ve got the laptop, umik, dual core, dennon XT32 etc.

Surely the mad scientist and you would be at least a little interested to see what they could do in my 20 foot high cathedral ceiling open floor plan house.

Also, I have no idea how to tune a passive radiator sub but is it possible to put only 1 radiator on the bottom while the active driver is firing forward? I’m just thinking that would only require one grill.

Just out of a general question, does two radiators allow this speaker to be tuned lower?

The one in my office? That's nothing I would need feedback on. It's not brand quality. Appreciate the offer of course.

Just out of a general question, does two radiators allow this speaker to be tuned lower?

A pr is tuned by mass(weight). I've seen them DF...I think that goes all the way back to the old velodyne 15-12 and 12-10 series? Or did those have the active DF? The problem with a heavy/mass PR is there's no electrical restoring force. So, over time, you can get into significant offset as the weight causes the cone to pull down. So instead of having say 30mm each way of linear xsus you might end up with 25 wach way, then 20 each way. If the system have been optimized for its very limits in that regard you're going to run into serious longevity problems along with audible distortions as well.

Two other nice to knows about PRs. The basic rule of thumb is to have 2x the air displacement over the active driver. There's ways around that but you still want a minimum of 40-45% more displacement IME. But even this, like just about everything in design is dependent on other considerations. Second, high mass PRs need to have their force cancelled by a second opposing (identical) PR. Well, I guess "need" is open to debate.

I built a few sonotubes with the PR up-firing back in like 97-98. remembering measuring the change in FR and THD as the PRs began to "sag", But I haven't seen those notebooks in a long time and I lost interest in all of that pretty quick anyway.

Well, that would suck to have a speaker that decreases in Awesomeness over time! Perhaps just a big massive 18 or 21 inch driver with a huge surface area port. Regardless of box size, this is a speaker for bass heads that want to shred drywall, organs or simply impress themselves each time they play a movie. For those that want to stay with the Low/mid bass approach, there’s a whole other lineup of PSA subs for that.

I just have a hunch that the speaker would sell more than is predicted, Especially if it’s not quite as tall as a v3601.

If we're playing the wishing game, I wish PSA would make a V1811 except maybe 4-6 inches taller, with a tune somewhere in the 12hz range. Is that even possible? Hell if I know, but I'd trade up to a pair
