4 speakers in a large room


Would appreciate some opinions about connecting four bookshelf speakers in a large room at home (the room is an open space where I have kitchen and dining/living room).

I have 4 bookshelf speakers (Dali Spektor 1) at the corners pointing towards the center. This is for ambient sound, easy listening while I’m cooking.

I don’t have them connected to an amplifier yet and my question is: should I hook them as two stereo pairs (A and B to an amplifier with two sets of outputs); Or should I search for an amplifier providing mono outputs, so all speakers play the same? Which option is the best for this kind of arrangement? I know in Pro Audio, the speakers at a venue work in mono. Should I do the same? Will two stereo pairs sound “strange”?

Does the A+B on the 701 use series wiring?

I've never tried A+B, but think my old Carver MXR130 may have that option.

If you already have a stereo amp to use stack them tweeter to tweeter (wired in series) and position them to cross towards the middle of the space (for starters).

Series wiring would be amplifier + to speaker 1 +, speaker 1- to speaker 2 +, speaker 2- to amplifier -.

You could try this with cheap speaker cable to see if they will properly fill the space when stacked.

Another trick to get more ambient/room filling sound would be to place them on very low stands or even the floor, but with the front tilted up a bit (you could try this with a single pair or a stacked pair).

Series wiring (your speakers are rated 6 ohms) would theoretically let the amp see 12 ohms, but realistically the load would probably be closer to 8 ohms.

Stacked 6 ohm speakers wired parallel would most likely drop well below 2 ohms - not a good thing.

Just found this simple test on Quora (though I've read similar takes elsewhere).

 

"Almost always the speakers were just paralleled.

It's easy to tell. With just one set of speakers on A,

if A+B parallels them then the speakers will continue to work going from A to A+B

If A+B places them in series then switching from A to A+B will silence the speakers."

Something else to consider...

I used a vintage KLH Model Twenty-One table radio in various apartment/house kitchens from the late 70’s up to the early 90’s.

Now there are nice vintage/retro look BT ready radios (and powered speakers "only" that look like radios) available which could be placed in the kitchen area and mated to an iPod or something similar.

With this method you could better implement whatever system you place in the main area.

Even though in some of the homes the main stereo was easy enough to hear in the kitchen area I didn’t wan’t to fuss with the good gear (tape/LP sources) while cooking, thus the radio.

When entertaining guests seemed to like listening to the KLH, though after dinner we would usually listen to the main setup (up until I purchased a TV with a screen larger that 6" in the mid 80’s;-).

This said, I’ve never owned a smart phone, never streamed aside from listening to music on the iMac - if that’s even considered to be streaming, and my wife’s iPod has only been used to take photos - so maybe it’s a dumb idea.
