Mmmhh...I was thinking of making them open, by destroying the rear baffle, actually.

Hi, and the short answer to that is no, rgds, sreten.

FWIW such systems usually have a very cheap 2 or 3 way built
into the front driven by one amplifier, and a hidded rear driver
in a 4th order bandpass with a large front port driven by the
other amplifier. As well as an active x/o they may or may not
have EQ built into the amplifiers, its anyones guess. Without
measuring and modifying, a very difficult set up to improve.

Thanks sreten, that's what I needed to know.
I know it's just a micro system, but having a mini disc collection, I was just concerned that if the speakers went, I'd lose the functionality of the whole unit.
Guess I'd better get onto Ebay and see if anyone is selling a set secondhand (a preoccupation of anyone with obsolete equipment).

You guys have lost me completely here.

This isn't very hard, is it?

Those Q Acoustics Concept 20 are biwireable 4-6 ohm speakers, whatever that is worth.

But you can bridge the woofer and tweeter inputs and run them off a single cable. The bridge is shown below. Seemples. Then behaves just like any other speaker.

Hi Steve, you are right, and nice choice, I too have the white ones.
But we're talking about the Pansonic speakers, not bi-wireable but bi-wired, as in they have two wires coming out of the back of the speaker.
One goes to + and - on the high frequency output of the amp and the other to the low frequency output of the amp, in other words there are 8 speaker terminals on the amp, presumably the crossover is inside there too.

Well, you can connect your Q Acoustics speakers to either output. Nothing will break.

Presumably one output will sound bassy, and the other output will be top end only if it's wired and filtered as you guess?

Sounds interesting actually. Poor man's active filter. What is the model number? I expect google can turn something up.

BTW, these sort of old stack units often have provision for an equaliser. It possibly won't work at all unless you bypass the equaliser input and output section with some phono leads.

Interesting, you are one step ahead of me Steve.
The unit's in my daughter's bedroom so I can't look until tomorrow.
I'll post model number, you may find out something.
Regards, Julian

Hi,

Steve is one step well behind any commonsense.
I've already described the commonsense.

In all reality you need to convert your minidisc
collection to VBR MP3 or WMA via a decent PC
card, or buy a standalone minidisc player/
recorder, they are now dirt cheap.

So go for the most expensive and rare,
not much more than the cheapest.

However that wil only delay conversion
for one generation, but at least your
source for conversion will be much
better than a mini system, unless
the mini system is the recorder.

rgds, sreten.
