Best wireless stereo setup in 2 lacs budget

[sbg]

I am also wondering what is the difference between a pre out and sub out in an amp. Marantz pm8006 only has a pre out and no sub out whereas 7000n has a sub out. Is there an advantage in connecting the sub to sub out over pre out?

So if I use the pre out there will be some overlap between the main channels and the sub. Is that really a concern?

yes possible. could go either way - boost certain freq or it can null out and end up in frustrating your required flat lines across whole band.

sub and main linkage is not very simple. there are also harmonics which need to integrate and there will always be integrations across the entire spectrum.

Eg the fundamental of 100 Hz of a guitar also has a subharmonic of 50 hz and of 25 hz. while 100 will be reproduced by the speaker the 50/25 may be by the sub. Since the sound texture/tone is defined by the summation of the fundamental and the harmonics how well the 2 integrate is very important for sound quality.

Simply put, no.

Connect the pre out to the pre in/line in of the sub and adjust the crossover. Depending on how high you set the crossover and how low your speakers can dig, there can either be an overlap or not.

Is that really a concern?

Not at all.

Also if I use the sub out in 7000n would it apply both high pass and low pass filter? Meaning if I set the low pass at say 80hz would it roll off the high frequency at 80hz for the speakers too?
