Imagine a 2121/66



Then bow down before it's majesty or be blown over!

Btw I have no clue if this is thing is crap. The idea of it is too ridiculous to pass up!

In a refridgerator size box with a big poweramp, lowpassed at 160 yeah it'll produce.

I wonder sometimes just how much paper cone you can glue around a coil before it gets floppy/gets ripples/waves in it and doesn't act like a piston anymore.

I understand the mids and highs ripple off the cone but I thought real bass came from a piston effect.

[will33]

Seems like you'd need a decent 10 or 12 or two for midbass/lowmids commiting yourself to a 4 way system. 3 way if you don't use tweeters.


I'm sure someone who gigs a 112 combo with a 4lb. amp in it will come along to tell you how impractical it is.

What's the point?

We have 10's that go down to our lowest audible frequencies. They sound punchy when they do it too. 12's are great too. 15's are less punchy but give you that kick in the chest.

Most bassists don't even use 18's because of their floppy sound and their tendency to fold without serious compression that many of us don't want on our bass signal.

I think that would be a huge waste of money unless it's only ever going to see prerecorded music that has already been cleaned of pretty much all dynamics.

if you are going for looks, it'd be really cool

Can we seriously stop spreading misinformation? Please read the FAQ.

yeah, if your using cheap 18's they will be crappy. high quality 18"s use reinforced cones. i use evx 180b and it has kevlar threads molded in the paper. the cheap ones are sluggish because with normal paper, the cone has to be very thick. the moving mass is heavier. even the 18" cabs made for bassists dont go that low. the drivers are average quality. i think 4- 10's has about the same cone area as an 18. if you took four 4x10 cabs and put them next to the 4x18 in my avatar, it would be embarrassing for the 4x10's. more bassists (like mike gordon) are stepping up to 18's. there is a big sound difference.

[Never_grew_up]

I'd be afraid the magnetic field from 4-410's or your 4-18's would make my watch stop.
It would be kind of fun to watch the lights dim every time I dug in on the low B...

I think the definitive work on these drivers is The Legend of EL PIPE-O (warning: PDF).

Keywords: Sonotube, tuned quarter wave pipe, 20 Hz.

[allexcosta]

21" subs are quite common and some folks dig the flavor it offers... Nothing especial here... Yorkville has had one for years...

Yorkville Sound: élite

Pretty poor choice for bass, if you ask me, but some folks dig low F#'s, low C#'s, etc...

interesting concept--are the things he's saying accurate?

[WhoDidTheElf]

Some one should make a 4-way system with that with an epic cross over.

One 21" plus one 10" plus one 6" and a tweeter.

That would be one heck of a full range cab.

[Yvarg]

Well, if we're going for larger speakers, might as well jump to this one:
Precision Devices International Limited

For me, I'll stick with my 18"

Well, I haven't built one of those myself, so I can't personally confirm that... but look around the rest of Pass Diy (and the related commercial site Pass Laboratories). Looks to me like he knows what he's talking about.

When I was a kid I saw Hendrix with Billy Cox. Billy was using four cabs with an EV 30" speaker in each. No definition at all, but lots of bottom. And very manly.
