Bi-amping????

I appreciate all you guys help, many questions have been answered.

Thanks Again

I passive biamp myself and use one amp in stereo for the LF and one for the HF. Even though there is no active crossover before the amp and the amp is sending all frequencies to the speaker the amp is only "loaded" at the frequencies the crossover limits. Although I didn't need the extra power of the second amp there was a sound improvement in my setup. I have biwirable speakers. As a former owner of an NAD 2200 I can't stress enough to remove the crappy stock hard wired power cable and replace it with something good. When I did it I went right to the fuse/transformer and bypassed the switch (when you open it you will see why) and used a power conditioners switched outlets as the power switch. HUGE improvement! I wouldn't try bridging, also aren't your speakers 4-6 ohms and not 8? You don't want to bridge that amp with a load under 8 ohms. I think you will like the sound best when one amp is loaded by the woofers and one by the top end. Let us know. And really change those cords!

Whoaru99 and Gregm have filled in some of the gaps. I have learned a little more myself.

Here is a popular link to an explanation of biamping and passive vs. active crossover configurations.

Having too much power is not necessarily a problem, just use it judiciously. It gives the amp "headroom", allowing for a lot of sound without stress on the amp. It will keep the amp from clipping at higher volumes which destroys tweeters.

My little Arcams don't create enough juice to hurt the Magnepan tweeters. The 1.6's also have a fuse in line with the tweeter section. I am not sure the Paradigm does.

Hope this makes sense?

BTW - The next thing I want to do is add an active crossover. This will allow me to bypass the passive crossovers, which seem to be generally regarded as a weak link in the 1.6's. It should also lessen the load on the Arcams, allowing them to do the best they are capable of.

One of the biggest benefits of active biamping is being able to tailor the amp to the specific needs of the speaker section it is driving.

For example, in an active biamp situation, if the mid/hf section requires 50 watts and the low section requires 200 watts, then a 50 watt amp and a 200 watt amp are all you need. This works because each amp only has to be sized to match the voltage swing necessary for the filtered range of frequencies being amplified.

In contrast, in the typical passive biamp arrangement, if you are using a 200 watt amp for the lows, you also need (should have) a 200 watt amp for the mids/hf. This is because even though the mid/hf amp is actually using only a small percentage of power from that 200 watt amp, that mid/hi amp still has to be capable of reproducing the entire voltage swing of the full range/unfiltered signal. If it cannot because a smaller amp is used, the waveform to the mid/hi will clip before the amp driving the low will clip.

Only information I have on the Paradigm monitor 11's is that they are"compatable with 8 ohm". The crossover built into the speaker is 3rd-order electro - acoustic at 2.0kHz; 2nd order electro - acoustic at 600Hz (lower bass drivers).
On the web site jim mentioned( sound.westhost.com/bi-amp.htm) they say most common question I get is ...

"Do I need to disconnect the passive crossover in my speakers?"
The answer is ... Yes, otherwise you are not really biamping at all.

If this is true then you literally straight wire your speakers to the terminals? taking out passive crossover in speaker? If so then do you use electronic crossover with same frequency as passive(out of speaker?) and where do you run the electronic crossover? before power amp?
