Bi-Amping, best way??

Run one stereo amp per speaker.. In otherwords dedicate one amp to run your left channel using the left or right channel to power the woofers and the other open channel to run the mids and highs.... This is verticle bi-amping, reason this could work out better than Horizontal bi-amping is that you can use a little longer interconnect and set the amp closer to each speaker with shorter speaker cables..

However, this is not the main reason for doing this, it is because especially if each AMP has a single power supply or transformer in it which most do unless specified as a Dual mono, than you are now Splitting the power supply with about 20 % to the mids and highs, and 80% left over to run your bass. Why? Because if you run one amps in the horizontal config for both Bass drivers in both speakers than you are now splitting the signal with less power available to the bass drive at 50% each.

Your mids and highs do not take much power at all, even if not the most efficient speaker, its normally the bass load that will cause the draw from an amps caps and transformer, so now in a verticle config you are not wasting one whole stereo amp seperating that power supply to just run both channels of mids and highs? Sorry if this is hard to understand but its as basic and graphic as I can explain on the internet.

Good luck, just think about it and it makes sense, do you want to dedicate one amp to taking on both Bass units? Or have a bigger reserve for bass current simply just talking a stereo amp per channel, by the way then you just need a basic jumper to connect the left and right channel RCA's right together on the same amp with the same signal, and you get less crosstalk as well cause you are now just running all one channel thru one amp instead of splitting it.

dave@z-cars.fsnet.co.uk, Yes just simply dedicate One amp to each speaker... Run both the channels with the same signal into the speaker, for example use the Left channel of the amp to into the Low section and the right channel of the amp into the top section... ONe amp running one speaker, and the other speaker gets the other whole amps 2 channels dedicated to it. Use your splitter or jumper to give the same signal to both channels on the amp... So you take your preout of the preamp left channel and feed both the stereo channels on that amp,, and same for the right preout dedicated to your other stereo amp.

Cool let us know the difference between the vert and horiz.. Thanks

"Ok, i've tried Vertical bi-amping with 1 amp for each speaker, and the sound was much fuller, and the mid-range was a lot stronger, i think my wife described it as been more 'in your face' (she's a violinist), so though i'd swap things around to horizontal bi-amping with one amp for hi's and the other for lo's, and with her fine-tuned ear she was saying that there's less mid-range but you can make out all the instruments and a lot more detail and colour (not coloured, as in valve amp, but sparkle and life), but not as much force....."

This statement re-enforces the point of that you have better power reserve for the midbass and bass when verticle bi-amping, but the sharing of one power supply in one amp for your Mids and highs in Horizontal config. seems to prove that the more rolled off sound occurs and a little less punch on the bottom.
