Silver Flute 8" woofer

This would be my first post with diyAudio forums. and im turning here in a last attempt to find out the answer. A customer called me today and asked me what the cheapest 8" sub would be to put in his truck. So i said 2 of the Silver Flute 8" 4 ohm subs would be perfect and i todl him the price of 39.99 each.
Now i have no doubt that theese are nice woofers, but my question to you guys is how good would the two of them hold up against one 10" pioneer.


which can be found here:

A fast response would be appreciated. thanks alot.
 
my line arrays

Oh yeah for sure. I built the most economic speakers ever. and i challenge anyone to second best me.
The line arrays have in each side:

16 4" full range pioneer drivers - 49 cents at parts express.
2 1 1/8 dayton silk dome tweeters.

the overall theoretical effeciency is 97 db. and the only speakers i've heard that have bettered theese were a 5000$ a pair B&W speaker.. but im sure a good filter and some better tweeters would fix that.

They peak real bad at around 8 khz. so a filter is almost nesesary. but theese things scream and after wood and crossovers it only cost me 100$ a pair.

thanks for your interest.!

I was thinking of building a box like this;
Scroll all the way down to Three Chamber Single Reflex Bandpass Enclosure with 2 - 8" Dayton Classic Woofers;

http://www.partsexpress.com/pe/showdetl.cfm?DID=7&PartNumber=295-310

Instead of Bandpass they were going to be 2 closed boxes with the front wide open instead of just a port.
2 - 8" Silver Flutes would also be good. I don't have the info on hand but I think the Silver Flutes even model well with a small ported box.

Hi-

The reason I was interested in the Pioneer 4" drivers is because I have a case of them in the garage also.

I was going to do an 8-12 driver line with a 4-tweeter line on the side.

I see your tweeters are in the center of a single line.

I hope to start with a 4 woofer 2 tweeter pair and continually add drivers until I either run out of drivers or room. :D
 
the best way i found to do it was to put 16 of them. to keep the impeedence at 8 ohms. and maximize series connections instead of parralell.. because my 80X2 harmon kardon pushed them to hard wired the way they are. and then by parralelling the two daytons i gain sensitivity and drop them to 4 ohms to compensate. try my design... it cant be beat
 
Well I put a 8" Silver Flute through UniBox modelling program.
At a 100 watts it'll put out 111 db.
Also reading this article on cabin gain I shrunk the box to 3.1 Litres Closed with a Q of 0.9.
http://www.diysubwoofers.org/caraudio.htm
With two woofers it goes up to 117 db.
Xmax is never exceeded. Even up to 130 watts with one woofer.
Lowering the Q increases the box size.
Don't know if I would want it that small and that high of a Q.
Never built a sub for a car or truck.
 
I had a friend build my a 3000 high pass 12 db crossover

the tweeter is the only 1 1/8 silk dome that dayton makes.. SILK DOME, it is by far the best tweeter for the money... even up to 30 dollars more.. this design is awesome, hard to beat for 100 bucks. but i would use 16 full ranges if i were you.
