    Anyone out there know specs on these Avatar 212 Neo cabs - specifically freq response and/or sensitivity? No data on the website...

    This stuff is usually available, but not on the Avatars. As much as people rave over them I don't care too much, 'cept for curiosity.

    I know I've seen some folks here talk about using some software to model cabs and drivers - Thiele-Small parameters, all that jazz. I'm not looking to spend days learning all that, so I'm hoping some speaker techie has done this already for kicks.

    I do not have the Neo 212 but I do have the DeltaLF 212 and WinISD. Assuming the same internal volume (about 3.5 cu. ft.) and cab tuning (50hz) this is what I got.

    Deltalite 2512 (neo):
    F3 - 66hz
    F10- 45hz
    average sensitivity - 100db @ 1w/1m

    Delta 12LF:
    F3 - 55hz
    F10- 38hz
    average sensitivity - 98db @ 1w/1m

    WinISD can only approximate low end response and won't really tell you how the cab will sound in the mid and high end. That will significantly affect the tone of the cab. You can visit the Eminence site to get more info on these particular speakers.

    The alarming thing about the deltalite 2512 is its low excursion capability. Its Xmax is a meager 2.9mm compared to the delta 12LF @ 4.8mm. That means the neo's will distort long before the deltaLF. It is also interesting that the neo 10 has an Xmax of 3.9 which is "BETTER" than their neo 12. I can only draw the conclusion that their neo's are still in its early development stage and I would personally stay away from them.

    Here's some more:

    Deltalite 2512:
    Xmech - 17mm
    Delta 12LF:
    Xmech - 27mm
    This is a representation of the driver's mechanical limits. You can see that the Delta12LF is far superior in this regard.

    Some of the limitations of the Deltalite will be offset by the higher output but I don't think it is enough to stop it from distorting sooner.

    Anyway I would get the B212LF (in fact I did!) :D

    The 2510 is a decent ten but the 2512 is a mediocre twelve; second generation Eminence neo's are in the works.

    Thanks very much - this is the kind of info I was looking for. I was considering the Neo simply for the reduced weight, but I figured there must be some tradeoff.

    I'm only slightly literate in the meaning of all the speaker parameters. I assume your statements about the Neo's low excursion capability is why the cab is rated at 600 w instead of 1000w for the delta? As in much power=cone rips itself loose...

    But I'm thinking of pairing it with an amp of up to 1200 watts, probably less (700-800). Following the rules of thumb I've heard, that should still be acceptable, right, since my average power will be within limits?

    As far as I know the RMS rating of a speaker is a representation of its thermal capability and not mechanical. The mechanical limits of a speaker are greatly affected by the cab it is in. It is not accurate for a cab manufacturer to list its speaker's RMS wattage rating as the cab's mechanical capability.

    Many of Eminence's drivers can mechanically handle more than it can thermally so usually this is not an issue but this doesn't appear to be the case with the Deltalite 2512. You would probably be OK if you played a 4 string but with a five string you can theoretically blow this driver in this cab with a signal peak of 600watts. This would indicate it is a 300w cab for a five string bass.

    If you set a high pass filter @30hz this problem should be greatly reduced. It's a good idea to do this with all ported cabs anyway.
