Double Advent Questions

So I currently have a Sansui G6000 and a pair of refurbished OLAs. I love it, but I've heard the siren song of the famed double advent setup. I really want to get a second pair to experience this aural nirvana but there are inconsistency in the info I have found on these forums. I have a few questions about the setup:

1) the g6000 is rated at 65wpc. Is this powerful enough to drive the 2 pairs? I read one item suggesting that this receiver doesn't like 4 ohm loads. This leads to my second question:

2) is the preferred wiring setup in parallel or series? Ive read that both are right. Clearly, if it is parallel, then the 4 ohm load could be a problem, but if series doesnt give the right setup then I would have to do parallel.

3) if parallel is the preferred method, is it possible to achieve good results using a speaker selector with a protection circuit? If I understand this correctly, two pairs of speakers can be run at the same time, but protection only causes the reciever "see" an impedance of 8 ohm and not 4 ohm, right. Would this setup work?

I appreciate and welcome all comments and help. I am fairly new to vintage audio, so I am looking forward to hearing from you.
Thanks!

I ran two pairs off of two Marantz 1060 for a while. Thats 30 watts per speaker. Sounded pretty good.
Im sure you could run them off your amp (in parallel) as long as it can handle the load
 
If your receiver has a speaker selector switch that allows you to run two sets of speakers at a time (A+B) then you should be fine. That said, I would still look up the minimum ohm load in the owners manual. 65 watts is plenty enough to drive them unless you are really cranking the volume. I've run stacked Advents in parallel with much less powerful amps with zero problems. I've heard some say that the more powerful the amps the better they sound. This is quite possibly true with any speaker.
 
If your amp is uncomfortable with 4 ohm loads, wire them in series for a 16 ohm load. This would be the safest for your receiver. If wired in parallel, for a 4 ohm load , they could dip down to close to 2 ohms at certain frequencies.

No. Not only does the Sansui not have the power but more importantly, it doesn't have the stability to run into a 4 ohm load.

To get the most from a double system you should have an amplifier with a very robust power supply and the ability to drive a 4 ohm load without any consideration.

Regarding your statement in # 3.....I've never heard of a 'speaker selector with a protection circuit'. That doesn't mean something like that doesn't exist, but I surely wouldn't want anything like that in any system of mine. Using something like that would be a huge compromise and would defeat the purpose of the double system.

If you're going to do this and you want to hear what can be a truly great sounding system then you need different amplification. Your current Sansui will drive them and they will make noise but they surely will not sound the way they could or should.
 
You don't want to put anything in circuit between the amp and speakers. If there is any question about the Sansui being able to handle 4 ohm loads (and, as oozure said, the impedance will actually dip down to 2 ohms at some frequencies) wire them in series. They will sound fine. I have done it before.

I have a quadraphonic system with four stacks of Advents and each pair has its own stereo amplifier now but I used to have them with the back pairs in series off a single amplifier and they were fine.

I continue to read recommendations on series wiring to protect amps, understood. Is there a benefit to wire speakers in parallel if amp is stable at 2-4 ohms, as far as SQ?

There absolutely is. Depending on the amplifier design most power amps sound great when running into 4 ohms. I have used SAE and Crown in the past and am currently using Bryston 3BSSTs running into 4 ohms. They are much more authoritative, faster, more in command. Bass is tighter and deeper (depending on your speakers) and the dynamics are almost frightening as the amplifier has much more current capabilities.

Wiring in series to 'protect the amplifier'.....that's a ridiculous notion. Any well designed power amplifier should be able to run hard into a 4 ohm load without reservation. If it cannot, then you need a new power amp.

Someone above mentioned wiring double Advents in series to a 65 watt per channel Sansui. Please......You need not bother setting up a system like this. As I said above, they'll make noise but that's about it. The double Advent set up can sound very good but it has to be supplied with a great deal of power.
 
Thanks for the reply. For too many years to mention, I have run various stacked speakers(8 ohm) in parallel with several receivers/amps and never experienced a problem.
 
I ran my Sansui G5700 with the Small Advent (4 ohm) with no problem. I blasted that setup too.
