The SR series

hellohello

Ive been reading alot about the SR 6500's, including the data sheet, i have it taped to the ceiling above my bed... mmm injected polyproplene...... anyway.. I was wondering if they were going to extend the line to include subwoofers, and if they did, would the subs have those phase plugs?

nadams

Polk has a new line of Momo subs coming out, supposedly to match the SR6500's, but they're not going to look the same. They'll look like your standard Momo subs. Their biggest sub (which is still in early prototyping), has dual Neodymium magnet structures and a maximum excursion of three inches! They're looking for a spider system that can move equally as far, because they're tearing up all the ones they've tried.

That sub looks to be a beast, can't wait to see it in action...

Theyre actually planning on coming out with a new Momo line AND a SR line. The Momo looks to be a lot beefier than the current line but the SR line looks to be a freaking monster! I mean a MONSTER! 3" Xmax anyone?

:drrrrooooooool:

3" is great and all if you have the motor to handle it. Im curious to see how these things work and am very excited about em

exalted- they have the motor to handle it... as I said. dual neodymium drive units, one underneath and one on top, to give a fairly linear power curve. one hits its limit, the other takes over

hellohello

...wooow... I may print this thread out and replace the SR manual with it
on a side note, if those new subs did have a phase plug, and the motor structure ur describing, im sure they would make a nice theft deterrent system, someone opens the trunk or door, a switch is triggered, a nice big burp of amplifier power, phase plug shoots off like bullet, either hits thief or scares him shitless

Toxis

subs don't need phase plugs... only midrange drivers and high end tweeters. It's to enhance imaging and staging, two things that don't matter one bit on subs.

MacLeod

Well actually they are to help off axis response and give a better frequency response by keeping freqencies coming from opposite sides of the cone from interfering with each other.

Have you heard it at full excursion? didnt think so. Ill believe it when i hear it

Give Polk a little credit. 30+ years experience designing and building speakers, I feel pretty confident they know what theyre doing.

with the amount of effort we saw go into the development of the SR6500s, i think we can trust them to care just as much about the matching subs... i don't think the pile of competitors' subs was there for looks...

Thom

I doubt the subs would have phase plugs. Actually, I'd bet against it.

neomagus00

but it'd look so pimp! no, not really, never mind... it would be interesting to see a subwoofer that is, visually, a replica of the SRs, tho, just for continuity...

exalted512

you should make them like the w7s where you have to take the ring out to release the surround and then screw them down under the surround...
-Cody

Toxis

the overroll technology is patented cody.

neomagus00

of course it is, it's jl... duh, cody...

exalted512

you cant do it different enough to where they cant claim it against you?
-Cody

Toxis

even halfway close and JL can still call it close enough for a lawsuit... and probably win.

hellohello

Thats why u need to do things completely different... like those square subs, who would ever copy that :rolleyes:
There arent any other square subs, but octagons, hexagons, triangles.... oh my :eek:

MacLeod

Dont be so quick to poo poo those square subs. Thos things will punch a hole in your chest too, especially the L7's. Now the triangle and other rip off subs (except Xtant of course) feel free to ridicule all you like.

hellohello

i didnt mean to poo poo the kickers, i didnt know xtant had odd shape subs.. but i just gotta wonder what they were thinkin when they decided to make 'em square...
"we have to make a bold statement,..."
"Lets make square subs."
"BRILLIANT!"
(read like that beer commercial)

My understanding on the Kickers is that the larger the surface area, the more air it can move. The square gives more surface area and utilizes more baffle space as a comparable round sub(lots of unused space between speakers if they are placed side-by-side). That, and it is a bold statement, both in sound and looks

What about reality?
I have heard good things about Kicker but not enough to make me want to buy a Square Sub...

audiobliss

What about reality? Sounds like he just told ya about it.

From what I've heard, they actually pound pretty hard and have really good SQ. But I haven't personally heard one.

I said that not because I didn't understand his post but because not many people is looking for Kicker gear around here... so even if they have a superior sub design in their hands they're not very popular...

audiobliss

I'll give ya that. Take me, for example. I personally don't care for Kicker.

MacLeod

Theyre very poplular. Go to any car audio competition and youll see plenty of them. OP is dead on, the square shape gives more surface area so a 10 will move more air than a comparable round 10.

Ive heard several of these and they do sound very good. I would have no problem at all owning one nor would I hesitate to take one into a SQ competition.

These are the Xtant subs:

exalted512

the 8s sound pretty good, they get worse in sq as you go up. But if youre looking for loud, youre hard pressed to find something as loud in the same power range in similiar installs. Especially the Solo X subs...jesus christ, it takes two mojos to push one of the 18s correctly.
-Cody

hellohello

those extants look mean, the x2, if thats what is called, looks better with the smooth cone
im guessing the folds in the cone act as reinforcement, like corrugated steel, or fiberglass

neomagus00

that might be a motivation... increased surface area is probably another, looks is probably another...
