Which driver for sonosub

[MetalMilitia]

hey guys
nice forum u have going here, i went to hometheaterforum.com and it has kinda died

hope someone can help me choose a driver as i do not have the pleasure of choosing the brands you guys have in the states

here are 2 subs that i can get relatively cheap, just wanna know if i'd be able to use either for a sonosub application tuned to perhaps 18-20Hz

MODEL: DBR-15
Fs = 26Hz
Qts = 0.7356
Vas = 5.71 cubic ft
Sen = 92dB
2" polymide coil (4 ohms)
70 Oz magnet
Santoprene surround

MODEL: TremorXR-15
Fs = 28Hz
Qms = 4.6012
Qes = 0.5582
Qts = 0.4978
VAS = 1.30Ft
Xmax = 0.5"
85dB 1W/1M
Revc = 6.67
Levc = 6.3mH @ (1 kHz)
2" Single Voice coil/8ohms

which would work better, i have not mentioned the brand name yet as i'm sure it doesn't matter but if need be i will
others have recommended JBL subs as an alternative to Adire Audio and the like

thanks in advance
regards

Neither of those are very good....

The high Qts rules out the first one. The second has a very high Le. That will cause the top end to roll-off quickly.

Any other options?

[MetalMilitia]

thanks for the quick reply

which values should i look for so i can try find a few more which are available to me with good specs

btw, what is Le for? (sorry i'm a noob)

How much are you willing to spend on a driver?

Edit: I see you're in South Africa which could complicate things and significantly add to shipping for certain brands and drivers.

Look around the net at the parameters for some of the more popular DIY home drivers.

thanks i had a look

i used the Tempest's T/S perimeters and cant find anything close to them

i found this though, a JBL

General
Frequency Response 20Hz - 400Hz
Sensitivity 91dB
Impedance 4 Ohms
Voice-Coil Diameter 50mm
Cut-Out Diameter 362mm
Mounting Depth 172mm
Overall Diameter 385mm
Vas 133 liter
Qts 0.44
Fs 28.36Hz
Qes 0.47
Qms 7.35
Sealed Enclosure (vol) 43L
Vented Enclosure (vol) 113L

it could work if i use 2, what u guys think?

[ThomasW]

We need to know the Xmax, and the Le

[MetalMilitia]

oops sorry it doesn't mention those values anywhere

is there not perhaps anyone from the forum who frequents South Africa as i will pay them to bring a woofer back from the States

someone TRUSTWORTHY

One can usually get info direct from JBL. Try their website or send them an email

[MetalMilitia]

think i've found one that will suite my application

Pioneer TS-W3002SPL 12"
1000w rms nominal
SPL: 89db
Le: 3,8 (series wiring)
0,95 (parralel wiring)
Fs: 25,5
Qts: 0,29
Vas: 1,315 cu.ft (looks a bit small)
Xmax: 0,43 inch

how do u think this sub will fair?

reason being i can't get any of these subs:
Adire Audio
Dayton
Splinter...

sent them an email, still waiting...

It's better than the other's you've listed

[MetalMilitia]

ok so things are getting better

i can get most of the car audio subs here in South Africa

is there not a car audio sub notorious for working well within the home theater too?

sorry about all the questions but i am not familiar with what distinguishes a car sub from a home sub

i know the home audio sub has to reach lower frequencies than within a car but thats about it

thanks for the help so far

[ThomasW]

It enough of a task to keep up with the DIY home audio products. As a result I don't have a clue what's offered in the car audio world.
