So what is actually WRONG with bits of pre-used 3-core flex, joined up with bits of choc block?I'm a spotify refusenik.

Nothing but I’ll be a millionaire so will splash out on Screwfix finest as a special treat.

That’s just extravagant. I’m not made of money yet.

When you say “bi-amped”, what do you mean?so, I've just set up the pmcs. bi-amped with my arcams.
first thing is they're huge! not as bassy as I thought transmissionline speakers would be but a very nice smooth and rounded sound. they really project.
got oak finish to match my sideboard.

Hmm. I can see that oak finish really ruining the soundscape.so, I've just set up the pmcs. bi-amped with my arcams.

I have a pre and power amp.
so I have the pre-amp wired to the highs and the power amp wired to the lows.

Um, don't the highs need a power amplifier, too?

If you’re not using some sort of crossover to split the signal into the highs and lows, then sending it to separate amps, you’re basically wasting your time…

none of the pieces I've read and also many set-up manuals from speakers I've had previously mention nothing of using external/additional crossovers to split frequencies when bi-amping.
the top amp I'm using is an intergrated amp with a specific power amp output which i run of course to my power amp.
If I run just the pre/intergrated amp on it's own in this set up, I can only hear the highs coming from the speakers, it isn't until i engage the power amp that i get a full audio signal.
hope that helps.

The idea behind running separate amps for hi/low is that you only amplify the specific frequency range that driver is going to reproduce. This means you maximise the available output of the amp as it’s only having to deal with things the driver can reproduce.
The speakers you’re using will have a crossover inside them, filtering out the amplified signals you’re sending. For any sort of performance gain you’d bypass that crossover, and introduce one prior to each amplifier stage. What you’re doing works, but you could save the cost of an amplifier by just connecting the speaker terminals together…

yes, but I have in effect one amp per driver. rather than one amp powering both drivers in each speaker
it's much better

It’s… a waste of an amp, tbh
but yeh you need a preamp with a crossover to really make it worth running 2 power amps. like this picture:
at the moment you are running 2 lots of "full range" into the speaker. whereas you need to run the "top" preamp output into 1 power amp and then the treble speaker, and the "bass" preamp output into another power amp and then the bass speaker. in mono.

Bass frequencies are usually mixed to mono.
yes bass is the one that def should be mono, I was half joking about the rest, although I run everything mono as I don't really want sound bouncing from ear to ear...I'm sure that setup sounds much better than mine anyway tho! because the speakers are nice and care has gone into it.

Yeah, unless you have a specific sub crossed over around 100Hz, domestic hifi speakers need to be in stereo as the “bass” drivers will be doing a significant amount of work in regions where stereo comes into play.
