LFE + NuPrime AMG STA or MCX-1 ?
« on: 6 Aug 2022, 05:51 pm »
Hello everyone,

I don't know which power amplifier to use with my subwoofer Focal 1000 IWSUB (700W / 8 Ohm / passive).

The LFE signal comes from the pre-out labeled "subwoofer" of my home cinema amp (Denon AVC-X6700H). See below.



Question 1 : Does the mono input of NuPrime AMG STA support LFE signal ?
Question 2 : I read output power of NuPrime AMG STA is 300 W (mono). I live in appartement so if I listen not very loudely musics/movies, are 300W enought to power the Focal 1000 IWSUB ?

Question 3 : Does the input "RCA" of NuPrime MCX-1 support LFE signal ?

Any advice welcome :)

Regards,
Rafael

Nuprime amplifier regardless of models simply amplify the signal that goes into it.  They don't do any cut off.
It is the job of the AVP that cut off high and mid frequencies for the subwoofer (active or passive). Why? Because you don't want to hear horribly distorted music or vocal coming out of the subwoofer.
It takes a lot of current to drive the subwoofer, therefore AMG STA is a good choice. The MCX-1 will do just as well too.
