I was wondering if anyone has used these speakers?

Aurasound NS8-385-4A 8" Woofer (http://madisound.com/store/product_info.php?products_id=8991)

Looks like they have good specs:
Aurasound NS8-385-4A 8" Poly cone Woofer

* Polypropylene cone and dust cap
* Rubber surround
* Neodymium radial magnet system (NRT)
* Underhung voice coil
* Vented magnet
* 4 ohm, 100W
* 38.55mm voice coil with copper wire on kapton former
* 8 woofers to a case

I picked up 4 of them. I'll let you know how they sound once they show up and I get them installed. :)

For ~$20 each, I figure its worth the gamble. They supposedly high excursion but it doesn't show the xmax specs.

What will you be doing with them exactly?

I know someone who is running the NS6 and he has a MECA SQ trophy from the last time he competed in Chicago.

I'd love to try the NS8 in my Mustang, but I think it is a tad bit too deep for my factory door pods.

Cool, I am very much into SQ myself! I don't compete yet, but want to this summer.

I will be installing 2 in the doors of my '65 VW Bus and 2 in the doors or kick panels of my '65 Beetle, depending on how much of a spacer I have to use (mounting depth).
I don't have any really good pics of the doors right now, but this gives you an idea. I'll be putting it in the largest pocket 4" away from the floor. I plan on crossing it over around 50hz with HPF set to around 3khz to a set of 1" silk dome tweeters (haven't decided yet).

You plan on using those up to 3khz? Good luck. There was a midrange shootout done using 4" woofers and the Aura got the worst rating of all of them...hopefully these are better but I highly doubt you'll get good results if you expect them to play that high. The site even says it's usable frequency range is up to 1.5khz, so expect it to be even lower than that...good luck man, you'll need it.

Now I see that in the PDF about 1.5Khz... If its too muddy or scratchy above those freq's I might have to suppliment them with some 3-4" mid-ranges to go with the tweets and probably a passive crossover from the mids - tweets. The main thing I'm after is very strong mid-bass up to 250hz or so. I find that most cars have a definite lack of mid-bass punch and that's what I'm hoping to get back with these. I have heard some Polk 6.5s that are very close to what I'm after, but I want to go with a 8" woofer for wow factor. ;)

2-ways with 8s starts to get difficult... you generally need tweeters that will play down pretty low and have good power handling.

He could always choose a full range driver like I did. ;)

I've been able to cross my Tang Band W4-1757SB over as low as 315 Hz, but recently moved it into the 500 Hz range so I could catch more of that lower end thump from the snare drum. It just didn't hit with enough authority when I had my MLI-65s playing from 80 to 315 Hz, so I brought them and the full range driver up.

I'm going to be using some Aura Whispers myself. :D But I'm ditching my Morel MW-267's to stay with 6.5's(no cutting metal this way).

Sounds like a good way to solve that problem! You don't use any tweeters at all? Just the 6.5's and these 4"ers? Is that your review on PartsExpress? :)

Tang Band W4-1757SB

Why that over W4-1337SD?

It had a better off-axis frequency response and I wanted to utilize the stock speaker locations versus building dash pods.

Yes, that is my review and no I don't use tweeters. If I had to do it all over again, I would consider something like the Fountek FR89EX, or other comparable full-range driver on-axis.

Those Fountek speakers look really nice also... So many choices in speakers these days.:)

nice! Could make a cool cheapo sub setup of eight of these 8s for $136 + one of the Boston Acoustic Factory refurb GT-24 amps on sale at BA's outlet site for $107 that'll do 900watts rms into 2ohms bridged and youve got some cheap, old fashoned, retarded fun for $243

I assume this is the driver in use, https://www.madisound.com/store/product_info.php?products_id=9007

or 4 and a cheapo bridgeable 2 channel... could be fun. Dang it! I think i just talked myself into buying some of these now...

It's hard to get any mid bass without a proper enclosure, But these do look like nice speakers. I bought the 6" versions but have yet to try them out

That definitely looks like the same driver in that powered Aura sub! (at least from the outside)

I've gotten a chance to mess around with these free air and - WOW!:naughty:

They seem to play well from ~40hz - 1000 or so and get really scratchy or boxy sounding after that.
I didn't bother building an enclosure for them, don't have the time and I'm going to be mounting them in doors. So far, I'm very impressed.

I was pushing one with a home theater amp with only 30-watts or so and the cone was barely moving (considering its free air!).
The suspension is very stiff, the spiders are nice, at least 7/8 roll spider :) I would say at least 1/2" xmax. The surround is kinda stiff for my liking, but feels very durable. I would say they can handle an easy 125-200W RMS (rated for 100). The magnet has no field which is nice for getting near crossovers (interference) and doors.

I found a set of SoundStream XTS6.5 3-ways I forgot I had. I'm going to run these with the Aura speakers to give me full range. :)
I also got a cheapie set of AudioPoop 3-way passive crossovers with a 500hz LPF on the woofer to drive these Aura 8's.
