I do have room for this and if kept to 35" wide, can be made to fit thru the door so . . . .

where's my cut sheet?

what's another 30 ish + ft^3 box anyway, just a few weeks worth of joyful screwin' 'n gluin'

amp? , some big Crown or something like that?

I can run another 20 or 30 amp circuit.

This will require an interesting router jig!

I guess the weight of this driver could require an internal magnet support brace?

The cone is pretty heavy, probably gonna take some serious power. Good thing we have lots of options!

Box could always be taller and thinner. Depth of the driver looks to be around 16-17 inches with motor (depending on which one). It's comically big. Should be darn fun.

Like Mark said, his sims are one thing, actually making it happen may be another but there is a solid goal in mind. Fit this bad boy into as small of a box as possible and still have it perform. If it ends up being 15 Cf? Then that's what we got to work with. Nothing set in stone as he's not even sure which way he's going to go yet.

But it's gonna be damn fun no matter what!

My enclosure is ready,

Just a few questions, how do you cross brace a dumpster? I'm going the dumpster route since my wife will divorce me and I can live it in as in the show 2 Broke Girls.

Will DIY SG be drawing up a 3299 for this new driver?

No its 14.7Cf using 1" wood.

You could go 34 x 34 x 22 = 11.8 Cf as well or a triangle in a corner etc. Lots of Options.

Keep us updated on the under 10 ft^3 sealed for a .707 alignment on that 32 and under $2k for the driver.

The woofer shipping crate should be made to be used as a the speaker box.
Just un-band it from its skid, add the electrical connector of your choice, and duratex it !

Personally, Id rather see the monster overbuilt! Something more of a sound quality driver first, its going to displace some air no matter how many sacrifices to overall output you make to clean up the sound and keep it linear!

Even if it drives the price up past 3k...

Show me a SQ driver that big!
That would be pretty sweet. A super woofer for the ages lol

The issues I see potentially are:

Does a single motor on a 32" cone make as much bass as multiple motors on smaller cones (with relative total cost of both) ? Does it make as good bass ?

If so, then what does a 32" cost vs say (4) 18" that do the same or better ?

That's how it needs to be priced.

The market will essentially support any price for it that falls in line with the above.

If it takes (8) $500 18" woofers to equal one 32" in performance and quality them you could price it at $4000 each.

But obviously there is advantages to the multiples approach so....

Given that the price probably should be somewhere that makes sense in comparison to other products on the market. Otherwise people will quickly educate themselves to the realism of the situation and sales will suffer. The p

I agree 100% although there are exceptions that break that rule. LMS for one, one of the most popular drivers on here, costs double a HST or UXL and only offers 5% more performance, still sold well. Once the drivers cost gets around 1K, you're into a Niche market anyways.


The new Rockford T19 Ricci tested, it's price of around 2K for A 19".... throws everything out the window but is over made etc. I'll bet you it sells like crazy because some people just want the best and don't care what it costs.

Either way, there will only be a select few that have room for a 32" to begin with, even SI's 24" would have a limited market but that doesn't mean it doesn't sell well enough to be a success.

At the end of the day, if you offer a unique product that fill a niche that people want, they will buy it regardless of price, as long as it performs well. Thats not to say Mark is gonna price it crazy high becuse it's niche, thats not the way he does business. I'm sure a decent price to performance will be found and hopefully lots of people will get to enjoy a unique driver!

BTW, here is the FSD's 32 in action : and the second vid is the russian 32" (same platform, motor etc. different cone) one in action

Some preliminary numbers:
Sd = 3,515cm2

Vd based on 25mm one way Xmax:
8.79 litres

Xmech of basket is 66mm

Voice coil hole in the basket is 179mm (7.05") so we would be looking at a voice coil of 6.2-6.25" which will accommodate a copper sleeve around the pole.

I've thought that manufacturers should rate this way as well, but have always seen it posted with the travel each way factored...until now.

Hm. To be honest, I never followed those things much, if at all. I can understand why they would post it that way though, given a full AC signal has both a positive and negative aspect. I guess if I was really 'playing the salesman' and trying to separate my stuff from others, I'd probably do the same.

Thanks for posting that though. I will keep it in mind.

Mark, I have to assume you know what you want these drivers to do and what kind of market to attack so I don't know what kind of suggestions you want from us. We can all make up our dream driver but it depends on what you are going to offer.

So I'm going to assume nothing until more specs come out.

But as far as pricing.... well, that depends of course on materials and build. It's quite obvious that your competition in this market is the Stereo Integrity 24"ers. Both the regular HS24 and the new BHS24. That's your price range right there. I mean, if this thing is a 60mm monster with a 6" copperclad VC and neo motor then it seems like an unrealistic goal to shoot under $2k per driver. Don't see how you'd make money at those prices. But anymore than that and you'll lose money because nobody will buy it. It's a tough game but you know how this stuff works.

I'd like to see rather reasonable specs and a price under $2k but if you want to go UBER 32" then I could see this thing going for $3k a pop. Maybe more. You could offer a "value" version that would be more suitable for IB use. That way the tooling for the basket, spider, cone, surround can all be used again and applied to some UBER version with a monstrous motor and voicecoil combo.

Just shootin' the s*** here but these are some observations and suggestions if you wanted them from us.
