Why so little bass when speakers set as small ( calibration advice needed )

[DuncanSWardle]

I have a fairly old but still quailty sounding Denon A1D amp which runs B&W 603S2 speakers at the front along with a CC6S2 Centre and some 601S2 rears

I have two subwoofers - a rel q100e and a rel qbass

I currently have it configured as follows

ALL speakers set as LARGE

ALL speakers at 75db(ish)

BOTH subs connected by phono connections and set at 75db

The REL Q100E is connected via the Neutrik Speakon connector to the centre speaker channel and set to SLAM

The REL QBass is connected via the Neutrik Speakon connector to the left/right speaker channels and set to DEPTH


With this configuration there is a LOT of bass, maybe a little too much and there is not too much subtle sounds, but for the films I like it tends to work

However so many people are now telling me I should set the speakers to small - I tried this and the bass almost disapeared - there was very little even during the most action packed of scenes

Can anybody suggest why this could be and is it ok just to keep it set like I have ?

You have the speakers connected in such a way that if you set the speakers to small, you cut the base off to the subs as well. You need a dedicated sub connection as all bass will be redirected there. I am not familiar with your amp, but I cannot believe there is no other way to connect a sub except hang them off your existing speakers..

Yeah you need to get the subs set to LARGE and all other speakers to small.

Don't know enough about your setup to advise how to do this.

BOTH subs are connected both ways ( via high and low level )

Take a butchers at this (http://www.sumikoaudio.net/New%20PDFs/rel%20lit/REL%20SUMSimpler.pdf) and see if you can figure out what may be wrong. I think it may be an issue with using the REL's crossover or using the amp to do it... Good luck...:)

Will the Q100E this doed not seem to be an option
