Now questions and/or comments:

Will my new Sony receiver pull 4 speakers 8 ohms or less? Basically, two speakers per stereo channel. If so, how should they be wired? Series, parallel, other way?

Why are 12 to 16 ohm home living room floor speakers almost non-existent on today's stereo market?

What killed the 12" woofer-equipped home speakers that were so commonplace in the 1970's and 1980's?

* Why 4 speakers? If you want surround sound get a home theater receiver that will provide the amplification for the number of channels in addition to decoding that sends the sound where it's supposed to be. The Sony says it has two sets of terminals so you could use two sets of speakers. I suspect using two sets of speakers will work but cut your output power. It may still be fine if your room isn't large. The Dayton speakers look to not need much power to drive them.

Why are 12 to 16 ohm home living room floor speakers almost non-existent on today's stereo market?

* Receivers today are made to drive 8 ohm, sometimes 4 ohm speakers. So no one would buy 12 or 16 ohm speakers. In short, just an industry change. There are some tube amps that still will use the higher ohm speakers and the speakers are available just few and far between. Look at Zu Audio speakers.

What killed the 12" woofer-equipped home speakers that were so commonplace in the 1970's and 1980's?

* There are still plenty of speakers with 12" woofers. JBL have some, L100. True though not as many as back in the day. The change was mostly trends, people wanted speakers that took up less room and looked more stylish. Some people argue multiple drivers will move as much air but I feel multiple drivers still don't sound like a true 12" woofer.

If you have it in the budget look at a stand alone streamer which is better sound than Bluetooth. The streamers provide an app so you can still use your phone. A popular unit is the Blue Sound Node. Or look at home theater receivers that include streaming function. If not something to consider down the road.

Anyway, how should FOUR 6-ohm speakers be wired to a 2-channel stereo receiver with A and/or B selector so as not to damage anything or make the music sound crappy?

Does either channel need two of these speakers to be wired in series?

i would read the owners manual to see how it recommends dealing with a second pair of speakers. My old receivers had a speaker switch that allowed to connect 2 pair of speakers A, B, A+B.

The 6 ohm is just nominal, impedance swings so the 6 ohm speakers will be fine. Keep it simple and just connect to the appropriate terminals, A to one ppair and B to the other. That way you can control which ones play or both.

I don't have the manual yet as the receiver is still in transit from amazon.

I read the online manual for my unit model and it states:


2: Setting/Connecting Speakers

Set up and connect the speakers according to the number of speakers that you are using.

This manual describes the installation, connections, and setting procedures using the stereo speaker system with A/B speakers as an example.

Note

• Connect speakers with a nominal impedance of 6 ohms to 16 ohms.

• When you connect all the speakers with a nominal impedance of 8 ohms or higher, set "SP IMP." to"8 OHM". In other connections, set it to "6 OHM". For details, see "6: Setting the Speakers" (page 19).

• Before connecting cables, be sure to disconnect the AC power cord (mains lead).

• Before connecting the AC power cord (mains lead), make sure that metallic wires of the speaker cables are not touching each other between the SPEAKERS terminals or on the receiver rear panel. If the wires are touching, it may result in damage to the amplifier circuit



Still, I am not sure if I should use two pairs of speakers with mixed ohm ratings. I am not sure if I should use an A pair with 6 ohms and a B pair with 16 ohms. The receiver has to be set for ohms rating. It's been many years since I have owned a home stereo. In the old days, there was no such thing as "setting" speakers.

In 1999, I bought a Technics receiver with no such SETTING provisions but the only pair of speakers I had were two floor speakers with 12" woofers. They were an 8-ohm pair. I did not use a 4-speaker setup then. Did not have the living room space.


In 1974, my family bought a new Electrophonic solid state stereo system with Garrard record changer, 8-track record deck, AM/FM tuner, guitar jacks and two giant 16-ohm floor speakers with "Air Horn Suspension" system and 12" (or 14"??) woofers. It had a switch in front called "4-channel" sound and the word MULTIPLEX was printed on it too. I never understood the MULTIPLEX or 2-CHANNEL SOUND parts. This system was heavy as lead and laden with wood and chrome. This was an awesome music-playing machine right out of the box for the 1970's consumer market. The Electrophonic also had a SCRATCH selector switch I think for a guitar effect. Yes, you could use this home stereo as a guitar amp!

It was similar to this one pictured but had a RECORD button and two tape deck mic jacks on front panel as well as a 4-channel sound switch.

In 1979, this stereo had to go into repair to replace a burnt-out tube if memory serves me correctly. This stereo's dust cover was missing as it had got busted by accident from a falling object back around 1975. It was awkward having the receiver panel under the dust cover. Rather inconvenient if you ask me. The big, heavy dust cover was not hinged, and you had to set this clunky thing aside to work the radio panel controls.

In the summer of 1979, I received the Electrophonic as a present for my room. I covered it with a pillowcase when not in use. My folks had gotten a new Sanyo complete home stereo with both an 8-track and a cassette record deck. The radio controls were on the front chrome panel and the only thing under the clear plastic dust cover was the Garrard record changer. This unit came with two 8-ohm 12" woofer floor speakers. My mother would occasionally borrow my Electrophonic 16-ohm speakers for a 4-speaker setup on the new Sanyo. It seemed that this Sanyo pulled a pair of 8-ohms plus a second pair of 16-ohms without any trouble. The Sanyo had A and B and A/B selector switch.

I think the 1974-vintage Electrophonic was a quadraphonic system and one would select to 4-channel sound with 4 speakers but the Electrophonic was never used with four speakers.

You could use a Niles Selector box or similar. 4 or 6 speaker models and some have volume controls.

From your manual

"" If you are not sure of the impedances of the
speakers, refer to the operating instructions
supplied with your speakers. (This information is
often on the back of the speaker.)
• When you connect speakers to both the
SPEAKERS A and B terminals, connect the
speakers with a nominal impedance of 12 ohms
or higher

I don't have the space for that. I just want a stereo receiver and one or more pair of speakers and that is all.

Does all that technical gibberish mean I cannot have one pair of 6-ohm speakers and one pair of 16-ohm speakers off that same receiver at once?

I was looking for simple YES, NO or I DON'T KNOW answers. Should I call Sony tech support and ask them?

Yes you should call Sony.

What our member was trying to tell you was: NO YOU CANNOT HOOK UP A 6 OHM and a 16 OHM speaker to the receiver at the same time. I could give you a technical reason, but it’s complicated. What Brian was trying to advise you to do if you want two sets of speakers is to use a speaker switching device.

JD you really don't want two sets of different speakers. The difference in impedance and sensitivity will make them play at difference volumes with same input power. Not to mention all the frequency cancelling and doubling.

On one of your threads I mentioned if you wanted more than two speakers like for movie soundtracks you need a home theater receiver. A home theater receiver will have multiple channels of amplification and you can compensate for speaker differences for the most part in the receivers settings.

Honestly no one uses 16 ohm speakers any more unless you have some type of tube amp that is made for that.

My suggestion is just use your new set of speakers with the receiver and at some point add a sub.

Mr. Peabody:


I plan to use speaker terminals A for the pair of Dayton Audio tower speakers I already have. 6 ohms a piece.

I read this article on incorporating a subwoofer to my model Sony stereo receiver which lacks a dedicated sub jack.

I like Option 1 since it involves no extra special equipment to buy:

Connecting a Subwoofer to the Sony STR-DH190 Stereo Receiver - All For Turntables.

CONNECTING A SUBWOOFER TO THE SONY STR-DH190 STEREO RECEIVER
Leave a Comment / FAQ / By Hanifa S
The Sony STR-DH190 stereo receiver, while a powerhouse for audio amplification, lacks a dedicated subwoofer output. However, it is still possible to integrate a subwoofer into your setup for enhanced low-frequency performance.

Option 1: Subwoofer with Speaker-Level Inputs:

If your subwoofer has speaker-level inputs, you can connect it directly to the speaker terminals on the STR-DH190. Run speaker wires from the receiver’s speaker outputs to the subwoofer’s speaker-level inputs. This method involves sharing the same signals that go to your main speakers, effectively incorporating the subwoofer into your system.

Option 2: Using an External Crossover:

Alternatively, you can use an external crossover between the STR-DH190 and the subwoofer. Connect the receiver’s speaker outputs to the crossover, and then connect the main speakers and the subwoofer to the crossover’s outputs. This allows you to set specific frequency ranges for each component, directing lower frequencies to the subwoofer.




Now my question is, would I hook my "speaker level" sub up to one of the pair of B terminals and play the receiver on A+B mode? Would the speaker setting still be for 6 ohms impedance?

The subwoofer is self-powered and self-amplified. It will only receive an audio signal from the B speaker terminals on the receiver. It should not put an extra load on the receiver, correct?

A subwoofer might make organ music more appreciable for listening and improve movie sounds to boot.

Is this video something to follow for wiring a sub into a Sony?

I think using "B" terminals for the sub is your easiest and probably best way to go. Option 2 in the video. Yes 6 ohm setting is fine. No harm to the receiver.

Once connected you will use the controls on the sub to blend it with your main speakers. You are on the right track. The sub will definitely enhance the organ and movie soundtracks.
