21-inch sub?

[clejw]

i saw this while browsing on partsexpress, it looks like a great bang for the buck, does anyone have experiance using this or another 21-inch sub in a bass amp? will it be too "muddy?" 1000w rms, goes down to 22hz, has sensitivity of 107db and its only 200 bucks...hmm

Tempting isn't it? I saw those a while back and thought the same thing...

I know EV had 1 x 18 plans (TL505)... I wonder if you could just scale those up for a 1 x 21 box.

Or maybe a nice 2 x 21 cab?

I imagine Mr. Bill Fitzmaurice will have something informative to tell us about the pros / cons of a driver that big.

My take: If you feel like playing around with it, and have the capabilities of building a box for it, contact PE and get the full T/S specs and model it in WinISD. A ported box for that thing would be around 6 cubic feet minimum, I'm sure! It lists the freq response out to 4KHz; I doubt it goes that high with any appreciable output. For reggae/dub it could be very useful, depending on box requirements. I.E. if the box winds up being the size of an 8x10 fridge, but only does "whump-thump" then it's uses are really limited vs. its' "PITA factor." MHO.

It's x-max will not likely let you take advantage of much below 40-45 Hz at reasonable volume - it has potential though...

yeah that's what i thought. i'm running a homemade cab with 115 and 2x8's right now, biamped though a sansamp and 1200w pa amp. it does great, but i'm looking for more spl headroom - was thinking an 810, but i'm not so sure now.

Wasn't this sub just brought up a couple of days ago??

---edit

Has anyone used this 21-inch sub?

"Size Matters" but not that much in speakers, where other things (x-max, cabinet design, etc) are more important. It's like "tone woods" in an instrument - they make a difference, but there are a lot of factors that make much more of a difference, enough that people can say "tone woods" (or "driver size") doesn't matter.

You can build a KILLIN' sub with a 10" driver if the cabinet is right. Conversely, just because a sub has a 21" driver doesn't mean it will sound good or have thunderous lows.

if i were to do this, i'd build a matching 8ohm 410 and use my same bi-amped rig...sorry left that out of my original post

yeah...something screwy is going on with my talkbass account and i never saw any replies and couldn't find it, so i thought the post didn't take. so disregard i guess...sorry

The PITA factor would be way too much for me to accept...

A 21" sub might make a good component for a high-powered PA system - depending on how low you really need to go. Not for a bass rig...

forgive my ignorance...what do you mean by "PITA factor?"

[KramerBassFan]

Pain in the a factor... you get the point.

Aka, its too darned heavy, with not much/not much usable output

[ThrashMaster]

What about these...Xmax is absurd!

HA!

Madison used to have cabs that had 18" and 21" drivers in them. They were built for the bass, and one was called the Hydra I believe.
