A crest factor of how much exactly? Crest factor is a measure of something, not a fixed static "thing" that "just is". |

Morin Amplifiers are measured using a Continuous Average Sinusoidal waveform and calculated (marketed/advertised to the public) to equate a Crest Factor value of 1.414 Best Regards,

1.414 is 3dB and is a simple sine wave. I don't believe Morin amps deliver sine waves at the rated power when almost identical looking and slightly more expensive amps from other manufacturers have similar power ratings but with a 12dB crest factor. |

Do people still believe in 2025, cheap China lightweights, will deliver published specs, into 4/8 ohm loads, at 40-100hz !?
Have said it before, if considering a bass amp purchase, borrow one, to see how it powers your cabs, playing your music, or go hear crew using your intended amp, on your music type. Buying lightweight amps, is about finding amp in your budget, that fits your needs, not looking at specs, then making a choice.

it's not about being Chinese or lightweight. Hardly any amps are specified to deliver sine waves at full power because that is totally unnecessary to play music. Elliott has tested amps and compared the Morin to other amps so must surely realise this... |

I do so love these bass amp discussions... Pure sine waves might not be strictly applicable to music, but reggae bass guitar, old skool dnb and dubstep often have some pretty sustained lf that's a close approximation of one. 20/40ms bursts are OK for kick, but I wouldn't appreciate using an amp that fiddles about with its output just because it doesn't have the balls to do what's asked of it! |

Agree completely.. Did mean to say, even the illustrious Powersoft X series, and K20 will ramp down quickly if fed 40hz input sine wave. But as mentioned by many, you don't need an arc welder to reproduce music. "Most" bass peaks are only ms. My experience of hearing Powersofts, QSC PL9, PL6, PL380, Lab Gruppens, MC2s, Admarks, CVRs. Sanways, etc, is, test amp you are thinking about before buying, go hear one playing in a gig. Not all lightweights are built equal, and the knowledgeable will know, there are almost no bass cabs out there, that are exactly 4 or 8 ohms, when playing music, so if your horn loaded bass cab, with "8 ohm nominal driver", is actually 12 ohms, the "weaker" sub amps (lightweight or torroidial) with fewer output devices, or anorexic psu section per channel, will disappoint.

I would say all over the West Indies, and many Reggae Crews in UK/Mainland Europe, have tried and love the Admarks, for 2-3x cabs per channel, on 2x channel amps. And Eliiot has been measuring and provided charts for these, for years. AFAIK, Powersoft do not rate the X8 for sub on all channels, just the X4L. So I "personally" wouldn't buy lower priced lightweight 4x channel for sub use, with 40hz HPF.
