search 15 inch Pro subwoofer ?
 
Hello GuYs !

I search to built a very efficient and soundQ subwoofer. (exemple : Altec A7 or ONKEN)
Do you know low budget quality 15 inch PRO subwoofer.

I search for :
* 15 inch PRO
* more than 97 dB 1w/m
* low frequency response 16hz or 20hz (without 10 or 20 dB drop !)
* for Bass reflex box
* not vintage woofer (new only)
* low price

Thanks in advance ;) !

Greets!

Probably doesn't exist at any price....... For sure the Altecs can't meet these specs. FWIW, the closest that comes to mind at the moment is the JBL 2245H at 95.22 dB/W/m and down only ~3 dB/20 Hz half space in 18 ft^3/20 Hz based on published specs, but it won't be cheap, at least by my standards.

Geez Nick, you don't ask for much do you? :D

As GM mentioned that set of requirements isn't gonna work. Pro woofers don't go low. They often have Fs in the 30- 40 Hz region. Good ones are often more than $200.00 each.

I can't speak for quality, but this Fane comes close to your requirements (though you'll be truly hard pressed to find one with an Fs that low, as mentioned here by GM and Cal).

Good for sealed or BR. Price is right.

There isn't a heck of a lot of program material between 16 and 40 Hz, really. So, if you relax that requirement, you could consider something like the Eminence Omega Pro 18". They're about 97 dB efficient, and will get to around 40 Hz. With a 4" voice coil, it'll handle quite a bit of power.

Take a look at the Eminence 15" woofers too.

Agree with dangus. Also look at the Eminence 3015LF. Does very well to 40Hz in 4cf/120L tuned to 40Hz. Cheap and light too.

Pro subwoofer
 
the FS is very high at 43 hz for many pro audio brands.


it's not complicated :

I search on ebay and I view many cheap PRO brands with the great specs but 40 hz is not very low for subwoofer use ?


In home audio or car audio the FS it's possible to have LOW FS (30 or 20hz FS)

with 20-2000hz freq range but I don't want this because DB is very low 83dB 88dB :dead:

I need high DB to put low power 150w RMS and have big result ;)


thanks !

nicK,

You have asked for a woofer with a low Fs
You have asked for high dB
You have asked for low price

Ain't gonna happen my friend. You will have to adjust your requirements.

DaveCan 13th April 2008 04:41 PM

Not exact for what your asking but lower fs than most.. I plan on using these in isobaric loading for what I want..
