Double Advent Wiring Question

Having just ordered my first new pair of speakers in 30 years, I am passing my "The New Advent Loudspeakers" to my daughter. Recently I found a used pair at a repair shop, so she will actually be getting a Double Advent system.

So, my question is, what's the optimal wiring situation? Not being an electrical engineer, I don't know serial from parallel, so I need my answer in as basic a form as can be stated. Her receiver has A and B speaker outputs, or we can run them both from just the A output, I guess. I'd like to know a bit about how it would affect her receiver as well, as in will it change the resistance, etc.

Thanks.

Re: Double Advent Wiring Question

All depends on what's drving it, parallel makes the most sense. If it's a minscule amp, it ain't gonna sound or work so good, 4 Ohms in praallel, needs some current. Those large Advents needed some WATTS...the more the better. After all these years the foam ain't all split and falling apart? WOW.

Re: Double Advent Wiring Question

What will she be driving them with? The original Absolute Sound article had a Phase Linear 700 with the speakers wired in parallel for a 4 Ohm load (about 900 Watts). I'm running mine with a Phase Linear 400 driving each pair (800 Watts). Make sure the woofer foam surrounds are sound. Try the pinch test and if they crumble at all you will have to replace the foam surrounds. GeoAli does a great job if you don't want to do them yourself. Just search them on Google. The stacked double Advents create a big sound, hope she has enough of a room to handle it.

She should be able to run a pair each on A and B. This will be in parallel and the receiver will see a 4 Ohm load. Or if the speakers are wired in parallel to the A speaker output the receiver will also see a 4 Ohm load, but you cannot put any other speakers on the B output. What kind of receiver is it?

Re: Double Advent Wiring Question

Connecting the speakers in parallel halves the resistance of the load the amplifier sees. Wiring the speakers in series doubles the resistance. Thus, connecting the speakers in series is

Re: Double Advent Wiring Question

Thanks for the help! She has a Sony HT receiver rated at 100 p/c, but who knows what it really is, anyway, it's got some power. I appreciate the explanation of the diff btwn parallel and series. Gonna take a look at those links as well. I really didn't want to run both A nad B together either, just didn't seem right.

Oh yeah, the surrounds are all new, I think on my original pair I'm on the third set. I've also got a pair of backup tweeters in case anything happens to the ones in the speakers. I bought the second pair of speakers from a very reputable speaker repair shop, and I actually saw them putting the new surrounds on.
