Hi, Just got an Eltax 6 sub for my 36zp18p. I can connect either to preamp line out or via the speaker outs. I have a problem tough... the preamp out connection sounds better, but the volume is obviously fixed (dvd is lower output than sky box so have to play with sub to et baance correct).the speaker out does have volume control, but the bass output sems lacking. My question: does anyone know if the speaker outs on a 36zp18p are limited bandwidth? The standard speakers are just small satelites with a so called 'super woofer' in the main cabinet. Im sure ive read that someone else upgraded the speaers to a set of Missions. Apart from no centre channel output, a limited b/w output would sound awful.... Ideas?
