Cabinet volume help for Faital Pro 10fh500 ?

Lets see, the Fs = 60hz, Qts = 0.26 and Vas is 23liters.
Hmm, since the Qts is really low the optimal cab volume wil be approx 16-18 liters and tuned between 60-65hz.
I don't have my simulation software at hand so this is a rough guesstimate on the cab volume and tuning

The good news is that the combination of high Fs, low Qes and small Vas does mean it gets maximally flat response in a 7 liter cab tuned at 60 Hz. The bad news is the f3 is 135 Hz. That's OK in the intended application, a PA midbass, not so much for bass. I'd put them in an EBS -6 dB alignment, 22 liters net per driver, with 50 Hz tuning. It's not as good a result as with a real bass driver, sensitivity is only 90 dB, but at least it's usable, not too big, and the driver has enough xmax to take the full rated 500 watts to still give decent output. The bad news again, though, is that it needs 500 watts per driver to give decent output. If you got a really good deal they may be worth it, but it's best to model drivers before you buy them to see if they do what you want them to, not after.

 

Below two simulations, 1st is 17 liters tuned to 62hz, the 2nd is 22 liters tuned to 50hz.
The latter goes lower but has a slight hump around 50hz, it will produce more low end but it will also sound a bit more sloppy then the 1st option which is IMHO the best option. Do you play 4 or 5 string? If you don't go lower then E then the 1st option would be optimal.

If you want to purchase the 10FH500's then for your application it would be best to put them in a cabinet as I suggested, it will have a tight clean sound sound.
Since these drivers have a solid xmax it's critical to have the sufficient port area, especially if you have an amp that can put out lots of power. What amp do you use?

 

No problem Brotha lima! I was on my cell phone (out for a smoke in sub freezing weather IIRC) when I posted that, so it was terse by necessity @fdeck is well respected here. I expect his on-line modeling software is top notch.

 

That's a pretty cool page. I've always been aware that the mainstream way of modeling a speaker is by analogy to an electrical filter, but never saw it laid out so clearly.

 

That amp is powerful enough to push these drivers to their xmax so I would use a flared 4" port, the length should be 23cm (9").
