    Hi, I came across a great deal on two Faital Pro 10FH500's. I'd like to build one or two cabs with 3/4" ply but don't know the optimum internal volume for a good bass guitar sound. I've used WNISD before but now I have a Mac (for work). Any help with a small cab design for a single or double ten cabinet will be greatly appreciated. Thanx in advance.

    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

    I appreciate your response, thank you !!! I will work with these parameters and I'll run it by you if thats's okay. (These speakers seem to want a very small box for high powered bass/midbass speakers)

    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.

    I play a 4 string bass and I am looking for a punchier type low end. I don't need a big low end (or expect it from these ten's) just want a really solid, clean sound. So, I'm looking for a cabinet that will help in that application. All of your help is appreciated.

    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?

    I use a Stewart 1.6 power amp from an Alembic FX-1 preamp and DBX EQ. I agree about the ports....What would you suggest for a 17-18 liter cab ? Dimension suggestion for the cab ?

    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 :D @fdeck is well respected here. I expect his on-line modeling software is top notch.

    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").

    BTW....I also use an fdeck filter inline from bass guitar to preamp to keep things tight. My compliments to the chef !!!!
