Which combination is best

[Kamranbites]

I have 4-8 ohms compatable amplifier, two pair of speakers  both different brand. now should I just connect one pair or should I connect both pairs in parallel. Both pairs ohms are 6 the only difference is in wattage one pair speakers are 35+35 and other is 43+43. What do you say?

[mariushm]

You can parallel the speakers, the amplifier will be fine.  In series, the impedance will be 12 ohms, which may be a bit too much for the amplifier. 

 

You should consider if it's really a point to use all four speakers, as 35w or 43w is already plenty of sound for a room or even an apartment.  Also, can the audio amplifier actually output that many watts?  

Note that the maximum power will be less at 8 ohm impedance and more at 4 ohm, but 6 ohm will be somewhere in the middle.

Also note that the maximum power of an amplifier will depend on the power supply used (there's some cheap amplifiers sold on Amazon or other places advertising 50w per channel but that may only be possible with a 24-30v while they're shipped with a 12v power supply) and the wattage may be inflated or listed at unreasonable levels of distortion (ex 100w per channel at 10% THD while the proper would be 60w at 0.1% THD or something to that effect)

 

If you can say the amplifier you have and (if it applies) what power supply you have for it, I may be able to tell you the actual capabilities of the amplifier.

I'll repeat what I said before. 

It'll probably work OK in parallel OR serial. 

You'd probably get better sound with just the better of the two speakers unless you're trying to use them in different rooms or on opposite ends of the same, large room. 

messing up your sound by having the speakers partially cancel out each other's sound (and partially double up other bits of the sound) doesn't make things better. Some people spend thousands of dollars on sound pannels to reduce comb filtering  from sound waves reflecting off a wall and you're setting things up in a way that makes it worse.

Here's a chat GPT response to "why is it bad to use multiple speakers from a single amplifier. Touch on electrical issues, phase issues, time alignment issues, comb filtering, etc.":

Quote

Using multiple speakers from a single amplifier can lead to various issues, including electrical problems, phase issues, time alignment issues, and comb filtering. Let's explore each of these problems in more detail:

1. Electrical issues: When multiple speakers are connected to a single amplifier, the total impedance (resistance) seen by the amplifier changes. This can result in an impedance mismatch, which affects the power delivery and efficiency of the amplifier. If the combined impedance of the speakers is too low for the amplifier to handle, it can overload the amplifier and cause it to overheat or even fail.

2. Phase issues: Each speaker has its own acoustic characteristics and can introduce phase shifts to the audio signal. When multiple speakers are driven by a single amplifier, these phase shifts can cause interference and affect the overall sound quality. The phase relationship between speakers can result in cancellation or reinforcement of certain frequencies, leading to irregular frequency response and poor audio reproduction.

3. Time alignment issues: Sound travels at a finite speed, and when multiple speakers are not properly time-aligned, the sound waves from different speakers can reach the listener at slightly different times. This can result in a phenomenon known as time smearing or time distortion, where the audio signals from different speakers interfere with each other and degrade the overall sound quality, particularly in terms of stereo imaging and localization.

4. Comb filtering: Comb filtering occurs when the same audio signal reaches the listener's ears through different paths with a slight time delay. The delayed signal combines with the original signal, resulting in frequency cancellations and peaks at certain frequencies. This leads to an uneven frequency response, causing a comb-like pattern in the frequency spectrum. Comb filtering can cause significant audio distortion and affect the clarity and tonal balance of the sound.

To mitigate these issues, it is recommended to use separate amplifiers for each speaker or employ audio processing techniques like crossover networks, time alignment algorithms, and equalization. These measures help optimize the performance of each speaker, reduce phase and time-related problems, and ensure a more accurate and balanced audio reproduction.

 

You should generally NOT be using multiple speakers in the same room unless you have an audio receiver that's designed for it and which is configured to take into account where in the room a speaker is positioned.

But what i feel is when connecting just 2 speakers audio is ok ok but when all 4 are together. it gives theatre effect,i don't feel any effect of combo or cancelling in my speakers, may be not noticable. orconstructive interference sound from both speakers  getting combined (sound waves) and providing more sound.

[Kamranbites]

I have two set of speakers one set is aiwa and other is Kenwood, i am connecting them in parallel i want to know what should be combination Kenwood+Aiwa or aiwa aiwa. Both have same ohms which is 6 and Kenwood speakers has higher wattage compared to Aiwa the difference is 8 wattage. So what combination do you choose to connect to a 2.0 amplifier?

[johnno23]

I would mix them Kenwood+Aiwa as you want stereo and will require them to be balanced.

the 8 watts is nothing dramatic but the volume is dictated by the volume control from the signal source amplifier 

doing kenwood kenwood aiwa aiwa as left and right wil create a terrible soundstage as any volume and also sound characteristics of each set will be very obvious and mess up your listening experience.

Like aiwa is 3 way speaker and Kenwood is 2 way speaker if I just mix both speakers will it cause any problem? Normally what it feels is connecting same brands together helps in more good sound and match frequency and characteristics of those speakers. Moreover I tired both the combination nothing different in both scenario the voice is same so what is your opinion should I mix them or combine same brands 

[johnno23]

if you are making a stereo setup with one set for left one set for right it is so out of balance if you do not mix them.

 

[johnno23]

3 way versus 2 way. 3 way is more like to push more air creating larger waves that will impact you ability to hear positioning of the band members or placement of orchestral sections.

3 way might have more bass resonance 2 way might have higher pitch if you ever hear a violin whatever.

the sound stage needs to be balanced so that when you sit in the optimal position the music sounds like it is around you and even in stereo despite all the dolby this and that you will hear the position of each band player. a well produced piece of music you will hear more than simply the sound but have an impression of where the drummer is in relation to the vocalist and the lead guitar is left or right of the singer or if the guitarist is singing etc. 

otherwise there is no point and you might as well just dump all the speakers in a box and listen to mono.

Yes it is a stereo setup but my main concern is i want a suitable combination were there is no harm to amplifier or speakers in long term

Like i said both are different brands also one is 2 way and other is 3 way if there is no problem then I will mix Aiwa and Kenwood one channel and other one same combination

Chat gpt view on matching speakers.

[johnno23]

you are using two pairs not 2 speakers

the above is only correct if you use one kenwood left and one aiwa right

you do you and listen to ChatGPT but it is wrong in this situation as you are not mixing a 2 way against a 3 way

you will be using a 2 way plus a 3 way together as one channel and the same for the second channel.

you stated all speaker had the same impedance..........I am out of here as it seems you are trolling me. just wire up the speakers and use your own EARS

You'll have some comb filtering even if you don't realize it.

If you want the "theater effect" see if you can get a used AVR. 
These have algorithms that take sounds which seem like they're coming from the left and put it in the far left speaker. Similar story with the right speaker. 
At least in the US you can sometimes find people selling older, used units for about the same cost as a 2 channel amplifier. I've heard of them going on sale for as low as $20 USD (though $100 on craigslist for a very old unit is much more common). In an ideal world you can even find one with HDMI, though the cheapest units tend to be analog only.

Ok thanks for suggestions 

[Heats with Nvidia]

By the way, technically seen the impedance of two 6 ohm loudspeakers in parallel is 3 Ohm and since you have a 4 Ohm capable amplifier. Its a little on the low side and it might distort a little earlier at very high volumes and even damage the amplifier if you use it on maximum volume for a long time like a party. But usually it will work just fine.

 

The 4-8 Ohm rating is only one for the customers that aren`t sure if it will work. Only tube amplifiers with output transformers need an more or less exact speaker impedance that should not be too high or you might damage the transformer. The much more common solid state amplifiers basically only have a minimum rating for the impedance, in your case 4 Ohm. Everything at or above 4 Ohm will work, even 2000 Ohm headphones, it will only result in a lower maximum output power.

 

When combining two diffetrent sets of speakers, the small difference in power rating won`t do much, but a difference in their efficiency might be more noticeable, because diferent loudspakers can have very diferent volumes when supplied with the same amount of power, but you would already have noticed this.

 

If you want to do this, i think cmndr has the best solution, get a used AVR. Then you can set those speakers to different volume levels and even just use one pair if you want to, without rewiring everything. Just get one that is rated for 4 Ohm or 6 Ohm speakers.

Pretty much everyone has told you to use one set, unless you get a receiver. You seem to not want to accept this despite it being the satisfactory answer.

Yes but if my amp support 3 ohms why not use all the speakers?

For the various reasons that have been listed in your many topics.
