There. How's that for some added craziness?

Best,

Whoa, that's just nuts!!

According to Data-Bass the UXL has pretty dang good inductance control, and a powerful motor.
I think the FTW uses the same motor, so one would expect it to perform similar.

I'd love to see a DB test of the FTW 21" directly though.

I'm really debating buying one right now. At $440, you get a driver that can potentially best the LMS-U... albeit with a larger box.

Ugh! Someone give me a reason not to?! biggrin.gif

Le 1khz 5.23 mH is what's on DataBass. I wouldn't say that was good. To quote "a rolled off top end due to inductance"

It's certainly a powerful motor and with great Xmax.

True, but it's really not that bad compared to most of the other drivers, especially ones with this much throw.
it's only maybe +/-4db to 200hz, not too shabby.

I'm curious to see those pics. I'd also love to see pics of your destroyed SI 18s or Dayton or whatever they were. What happened to those drivers before you threw them in the trash?

The SI's VC's burnt up and came completely apart. No pics. Re-cone or shipping them back was not cost effective as I got them for $340. I was building the subs a my work when they blew up. Pulled the cones, saw the VC's, pu them back in their boxes and never bothered to take pics, threw them in the dumpster and moved on.

Mark, seriously. I don't even know where I'd put these 21s. I want a pair. But then of course I'd need to ship another G to China.

Must go tile floors in.....house....instead.....

Its simple bro. Just give your wife a big hug, tell her how much you love her, at the same time mentioning you need a bigger house wink.gif

That's the Mach 5 Phallus right?

I just pulled the plug on a FTW-21 pre-order, wooo, can't wait. I'm thinking of buying a 2nd one even, and doing two 6cuft cabs.
At this price, these subs are a steal!
post #45 of 176
I'm in for 4 of these...now to figure out if I want to do sealed or IB. Yeehaw.

Yup the Phallus. The 6cf boxes are right about perfect for size. You don't gain a ton going higher in box size. It's a good middle ground. Although they will still be good in up to 8-9 and down to 4 CF. Just need the right amp.

Congrats Bricktop! You're gonna have one hellova fun time!!!!

Just wanted to check with some of you guys who know a lot more about this than I about the foam surround on these. Is there any reason to be concerned anymore about foam surrounds? Do they hold up as good as rubber surrounds? I am thinking that just like everything else foam has come a long ways over the years but I always seem to steer clear of the it. Will it degrade more as compared to rubber? Thanks.

your correct. the foam used here is nothing like back in the day and will not rot out. i would think they hold out just as long as rubber

+1. It took 20 years to find out the hard way that the foam used in the 70s through 90s would eventually deteriorate. Once that became known the formulation was changed.

Indeed. And it will take another twenty years to determine whether the new technologies will hold up. By then, folks would have probably moved onto an AM radio listening to talk radio in the kitchen while they are waiting for their buns to finish baking.

I'm almost ready for a deuce.eek.gif When are these expected to ship? Would 800 watts in a 5-6 cuft sealed box do ok?

Just ordered one to give the foam a 20 year test! smile.gif

No, sorry but gonna need more power or bigger box or ported for 800 watts. Some of us are using 2000 watts up to 4000 watts in similar sized enclosure. I use 2100 peak in 6.5cuft and they could use more.

These drivers needs lots of power just to get them moving!!!!

I can hook up my QSC 2450 and clip the amp WELL before they are moving 50% of their travel. Was disappointed that couldn't use it on two of mine that aren't driven by a clone. But was to be expected.

How do you like the Phallus? It looks awesome but I imagine UXL/FTW is better for subwoofer duty, and most folks around here don't need much mid-bass help.
How much power do you think these things could take in a 6-7cuft sealed box? I'm guessing the 1200RMS is conservative.
I was thinking two in seperate boxes, with a bridged Inuke3000 each, for DSP, and about 2000rms into each.

So anything less than a clone won't be enough for 6-7 cu ft?

Why can't you use the amplifier? Because you can't drive the speaker(s) to its (their) absolute limit(s)? You're ALWAYS going to hit a wall with one first (amp or driver).

Won't they produce 100+ dbs with just 20 watts in a typical enclosure?

I don't know where this idea that "big" drivers need more power emanated, but isn't the precise converse true almost 100% of time (all else being equal): that they usually produce MORE output with LESS power in an appropriately sized enclosure? I'd imagine a couple thousand watts into pair of these would produce prodigious output in just about any room.

Of course it would be "fine" for 99.9% of the populace, but this is AVS DIY where "more than enough" means you're almost half way there.

I guess it depends on how loud one wants to go and how deep as well. The deeper you go the more power you need. I run my 12 drivers off of one clone and then I ran 10 drivers(one sub per channel) on a 5 channel amp with 450 watts per channel. I was able to play movies just as loud. I know having the most is very cool but each room requires different setups to reach the same levels. One can save lots of money and put them into better speakers!

the phallus is imo more of a music sub. it still does dig deep and can rumble out the low stuff bit the uxl and ftw are better choises for pure sub duty. they have bigger coils, can handle more power and higher xmax. if i was building a music system, the phallus would be a great option if looking at mach 5 drivers.

Has anyone ever modeled out this driver in a Gjallarhorn type enclosure? + a few inches in width. I would imagine it be capable of outgunning the LMS in a TH if the specs line up.
