Any reason not to go with a Tempest for up to 80Hz?

    Due to my budget receiver, mine is crossed over even higher than 80Hz. Based on what I heard from mine, I think the Tempest will work fine up to 80Hz if you go with this driver.

    Should work great, I've heard them with 4th order xovers @ 80Hz and they were fine.

    The rule-of-thumb I use is to find the primary breakup mode (major peak near the driver's upper BW limit), and drop back 24dB, to put it near our built-in 'noise floor' for intelligibility, or ~32Hz/1st, 63Hz/2nd, 125Hz/3rd, and 250Hz/4th for the Tempest.
    In perusing the Tempest White Paper I notice they feel -20dB from the primary breakup mode is acceptable. Oh well, different strokes for different strokes! [​IMG]
    My only concern with 80Hz/3rd, is that if the sub is stuck in a corner, there may be some shift between the sub and furthermost main, making the sub position audibly obvious.
