# SB1000e Greybox File and Amp Specs
**Given the age of the SB1000e, there is no Greybox file available. While the SB1000e** **and SB1000z are nearly identical acoustically, because the components differ between** **the two, we don't recommend using the SB1000z Greybox on an SB1000e. The power** **handling is slightly different between the two which may result in unexpected limiter** **behavior if the SB1000z Greybox is used for the SB1000e.**
**There are recommended parametric, HFP and LPF settings you can use with the** **SB1000e, attached below for reference.**
**Regarding voltage peak limiting, I suggest setting this to 150V to allow the subwoofer** **to reproduce musical peaks ~6dB above its continuous operating level.**
