10" PA driver for FAST - possible?

[barackuda]

Hello all,
about to finish my B&W clones with Fostex FE168EZ Sigma.
Looking for PA driver to act as a helper woofer down to about 40-50Hz (enough for music I guess).
I have been searching the forum but no luck....
Any ideas?
I prefer highish sensitivity (to match Fostex), light paper cone, fast dynamic driver, budget about 150 euros/pc.

Thanks guys

Danny

Eminence are fairly sensitive and have a good build quality.

thanks for suggestion Jon,
I was thinking more of a higher class driver, for example no stamped basket, but cast would be nice

10" PA midbasses are easy to come by: a compact 10" plus tweeter 2-way cabinet is a fairly standard piece of kit.

A 10" woofer, however, will be more difficult to find. Woofers are designed to produce bass and only bass. In the PA world, 15", 18" and 21" drivers are used for that, as a 10" cone won't move much air in comparison.

What I'm saying is that you could easily use a 10" PA midbass. It'd have fairly high sensitivity, but not much in the way of bass extension, and will run into harmonic distortion quite quickly. They're not meant for low frequencies, and asking that of them doesn't seem wise.

On the other hand, check this out.

It'll do more bass than most PA 10"s, but loses some sensitivity.

thanks Chris...
I am not expecting the woofer to do sub frequencies I know better than that... What I want is that the woofer should be ok for freq from around 40hz f3.. or little higher... I know that would be plenty for music... at least according to spec sheets...
What I am asking is real world performance, dynamic, detail (I would run it up to about 500-700Hz? )

The Eminence driver looks very good, the sensitivity is not that bad actually...
I have to sketch it up to see if the flange shape wont be a problem....
thank you again....

Any more suggestion please feel free to chime in. Also any tips and hints why yes PA and why not for home use..

The KappaLite has a dip at 500Hz...perhaps not so good?

 

[barackuda]

oh, very IMPORTANT note:
I can't go above 256mm in diameter !!!

So the KappaLite is OUT

OK I just checked the drawing, the total maximum would be 273mm diameter, but that's extreme case.

And I still have to come up with the total volume damn I forgot about that one, that will be together with the diameter the major restriction.

Active or passive?

 

[barackuda]

Spiro:
Active for sure

 

[SpirosZ]

Not a PA driver but I remember when I was searching something similar for me that I liked the 10" SB acoustics SB29NRX75-6 - SB acoustics 10 inch woofer - Europe Audio
Since you are going active you can match the sensitivity difference.
I wouldn't cross it higher than 300Hz though.

 

[barackuda]

thanks for the suggestion but its a tad big on the diameter now i am calculating the inner volume, the shape is very difficult, so it will take me a lot of time... suffice to say, one box contains of 30 laminated pieces

 

[tuxedocivic]

You built the box before you had the driver?

Faital Pro has some nice woofers.

 

[barackuda]

I didn't build it yet, I have build the top section with the Fostex Sigma, now I am designing the bottom section to pass WAF.....
I have some sketch but need to calculate the volume and get a suitable driver

Danny

P.S.: here is the sketch

 

[tuxedocivic]

Oh, a B&W 800D clone kinda thing going on there.

 

[gafhenderson]

Beyma have some pretty decent bass woofers in every imaginable size.

 

[talaerts]

Since you go active, the sensitivity is less important if you use solid state amplification for the bass. Meaning, you don't need to aim for PA speakers.

Anyway, in the PA world, this one seems really quite cool:

Beyma 10G40 might also be suitable.

I know that for active and powerful amp I don't have to care too much about sensitivity.... Its just the quality PA drivers sound to me.... how should i put it... fast, really dynamic. Probably due to very light paper cone and million other things.... Simply put PA or very very expensive drivers sound to me much better than any other Hi-Fi woofers...

The Beyma range sure is interesting, price wise too.

What about the seas L26ROY woofer. It's a bit pricy and its not pa, but IIRC it can use a pretty small enclosure, is very high quality, and could go as loud as you would ever need.

Pro drivers might sound fast and dynamic because they are missing the low bottom end. I happen to like the sound of pro drivers too. They play louder and have a more effortless sound to them than some of the more delicate drivers many discuss on this forum.

they also have dirty great big magnets on them compared to most fullrangers. their BL to cone weights is usually much better which is why i think they do produce quite good detail. the full rangers are a bit wild for me however. i think the drivers need some mods to tame their rawness and the fact they're built to survive being played very loud, Enabl and frame mods etc.
