    Hey folks,

    Just wondering if anyone has any experience with these drivers?

    Here are main specs:

    12" driver
    Rated impedance: 8 ohms
    Min impedance: 6.4 ohms
    700 W AES
    101dB SPL
    25-4000 hz
    Voice coil diameter - 100 mm
    BL Factor: 23.1 N/A
    X Damage: 52 mm
    Xmax: 7.5mm
    45 Hz fs
    Qms: 6.6
    Qes: 0.15
    Qts: 0.15
    Efficiency 5.4%
    Net weight: 12.32 lb

    Could only find them available for sale in one place and they were listed as $361/ea.

    I might end up using it as either an 8ohm 1x12 or a 4ohm 2x12 sometime in the future.

    Also, if anyone has experience with the 15" version, the 15P80Nd, I would like to hear about that as well.

    Well...the xmax figure is impressive, but the price? -- ouch. The Beyma users I've talked to in the past seem impressed with the product, though I will admit I've never used them.

    I've always used Eminence speakers with good results -- maybe there's something in their lineup with similar specs?

    Bump for more experience?

    Know it is an expensive driver, and I was impressed by the stats - just wanted to know what others have to say.

    I have also checked out the Eminence line - I saw lots of very impressive drivers, but this one really stuck out to me, since I could also use this speaker by itself for an awesome 1 cab solution.

    hi BA, i have 2 beyma 15s that i cant identify, did you get the spec for your driver off the driver its self,ie a label because i can only find the ohms printed on the cone on mine. i will have a micro check on mine but with a standard scan i have found no way to identify them. i only know they are old. thanks

    Nope, got the specs off of the Beyma website and their datasheet.

    I really want to put these drivers into a cab - I know they're expensive, but others cabs with this much power handling and speaker quality are expensive as well. I could go the fEARful route, but I want something to be light - something around the 50ish lb mark. If I threw two of these drivers in, they'd account for about half of that weight, and it would be a massive 1400 W.

    Can't complain about that...

    And sorry, can't help identify your Beymas...I don't know enough about them yet. Pics?
  6. All I can offer is I am not believing the spec sheet.

    thanks ba, i will id these drivers one way or another even if it means pushing them a bit.

    4" voice coil, QTS of 0,15 and low VAS of 95,7 ltr all translate to me to a specialized driver meant for horn loading. Too highly damped for getting good bass response in a nEARful type of bass reflex cabinet.

    You should model the speaker, before you take the plunge.

    I trust Beyma's spec sheet. Beyma is a highly respected manufuacturer of premium drivers. No budget line here....

    I did a search for you in German and French but only saw a lot of raving reviews from high end PA builders and even hifi DIY as a mid bass unit. No bass guitar use as far as I could see. Maybe ArjanK has some more info?

    Would probably work very nicely in an EBS (extended bass shelf) type of enclosure. Then use a bit of LF boost to get the "bass shelf" up in level withe the rest of the register.

    Remember that TB has many US members that have less experience in European brands as Eminence is such a big actor in the American market. Compared to speakers from BMS, Beyma, Ciare etc, Eminence products are technically pretty un-impressive. I think most other manufacturers have woofers similar or better than the 3015LF, for instance. In the Pro Audio world, Beyma is considered a serious contender, while Eminence is more regarded as a budget brand.

    This is one of the reasons why I wanted to do a search across the market - I want to get one of the best drivers, not just whatever is available at a budget price. The way I look at it, I'd rather be more than thrilled with my cab, even if I have to pay a little more for the drivers, build etc.

    AFAIK, the Eminence driver that came the closest in my search was the Kappalite 3015LF. It's a bit lighter, less xmax and less power handling though. Freq response is 40-4000hz, so that may be another option.

    Yeah I found out about the brand through looking at it from the mid bass section, thought it could potentially be useful for a driver due to the specs.

    I could also make this a two way cabinet and put a 6 in for extended midrange.

    Appreciate the feedback so far, keep it coming!

    Bump for more exp. Really looking forward to putting one (or two) of this driver into a custom cab if possible

    Sure you're not thinking of the non-LF 3015? The 3015LF is rated to 1.5K usable response, but it sucks badly even there without a big EQ tweak, in my experience. The published Xmax rating is also actually higher than that Beyma, but differing rating methods make that another can o' worms...;)

    May 24, 2006
    You're absolutely right, why I typed that in, I have no idea.

    As for the xmax rating...

    The 3015 - 5.9 mm

    The 12P80nd - 7.5 mm

    And yes, the 3015LF does have a higher xmax rating indeed - 9.1mm

    Talk to me about different rating methods, I'm new to this and want to know as much as I can.

    I want a reason why I shouldn't use this speaker + a mid driver in a 2-way 1 cab solution. I want the ultimate mini-rig of doom. :bassist:
  16. Big +1 for this.

    A huge Xmax and high power rating do not in themselves make a good bass guitar driver.

    However, +1 to the OP for at least looking at other drivers besides the Kappalites (3012 &3015). There are other very good drivers.

    Okay, what would the ideal QTS, VAs and voice coil size look like for a driver with this kind of sensitivity, power handling and xmax size? Or more generally, what is the range I should be looking at?

    I want to make a 2 way, 1 cab solution, with a 5 or 6" mid driver. In addition to this driver, I've also pulled these other of which is a 15" and the other a 12". Are there any other drivers that anyone can suggest that come close to the specs I'm looking for?

    - high power handling
    - low weight (<20 lbs)
    - high xmax (and xdamage)
    - high sensitivity
    - good low end frequency response (atleast 40 hz)
    - can be any size driver, I'm not too picky about size

    Take a look at the BMS 15N630. I have a pair in 1-15 cabs and a variety of top boxes with midrange drivers and/or tweeters, such as:

    Mr. Escher, your DIY work makes me feel very inadequate. :( That is all.

    Funny, it often makes me feel that way too...;)

    But seriously, I've been doing this stuff for around 50 years and every time I take on a new challenge like woodworking or passive crossover design there's a new steep learning curve to tackle. Before we had the Interwebs so much of this stuff just felt like esoteric knowledge rather than science. That was kind of fun in its own way too though.
