    JBL L212/B212 Ultrabass - replacement amplifer - bass boost or not?

    I'm shopping a replacement amp for my B212 subwoofer, and according to some product literature (see first image below), the original amplifier ("Bass Energizer") has a 25Hz, 10 dB boost. Yet according to the service manual (linked here and "screenshotted" below), there appears to be no such boost.

    Can anyone confirm or refute the presence of such boost? (Of the plate amps I'm shopping, the most boost I have found is 6 dB at 25 Hz; see here.)

    Thanks!

    Eric
