Sony 37EX503 - External speakers

My wife has a slight hearing defect so we have a pair of unpowered, surround sound speakers wired under the floor to near the sofa, from the surround sound output ports on our old CRT Philips tv.

That tv is on the blink now and I have spent weeks selecting a replacement, I have decided on a Sony 37EX503 but not bought it yet.

Today I discover that there are no analogue audio outputs on the 37EX503, nor on the runner up the Panasonic 37D25, and I’m guessing probably none on any HD LCD tvs.

So, how can I connect to speaker(s) by the sofa for my wife ? I would like to keep it simple so that she just switches on the tv and the external speakers work but I appreciate I may be clutching at straws. I definitely do not want a home theatre system with subwoofer and an array of other smaller speakers.

I have had the following thoughts:

1) Use the optical audio output into my HiFI (Denon DM38) and put the HIFI speakers across the room, or connect my surround speakers to the AV aux outputs.

2) Connect a Scart/AV ouput connector to the new tv, then wire from there to my surround sound speakers – is this possible and will it work ? Does such a connector exist and will the output drive my unpowered surround sound speakers ?

3) Buy a “gizmo” that plugs into the headphone jack on the new tv that drives external speakers (I think some of these might come with wireless speakers).

4) Connect to the headphone jack and try and split the wiring out to connect to the surround sound speakers – will it be strong enough to drive them ?

All ideas welcome, ...I'm keen to get the new tv :)

I'd probably say a combination of 1 and 2, and use the analogue phono output from a scart adapter plugged in the tv to go to an aux analogue input on the denon.

Then hook up the surround speakers to the Denon. It will probably compromise the denon a bit, but it will suit your needs.

As the surrounds need some amplification you either go this route - or buy some active speakers with built in amps.

What do you mean when you say "it will compromise the Denon" ?

presumably you already have some speakers for the denon. As it only has one set of speaker outputs you would have to parallel the surrounds to the same set of outputs.

This would compromise the stereo field also the charactersitics and impedance of the surrounds being different to the mains would effect the way the denon drives them. It may not be happy driving lower impedances (probably 4 ohms )

You haven't stated what they are, but Im guessing they would be different from the mains.

In reality it would work for your needs - it's just not ideal from a hi-fi point of view.
