Balanced load

[Ajaysdisco]

I’m sure this question has been raised before but I can’t find the thread.
Quick question, can you run an amp unbalanced so on one channel you have one speaker (8 ohms, mid-top) and on the other you have two speakers (4 ohms, mid-top and bass).
Many thanks

I dont think this can be done but im sure someone will be here to confirm this or not.

Are the two speakers on one side 8 ohms each or 4 ohms each?

Most amps have seperate output channels and are not linked unless run in bridged mode. So in theory it should not be problem however would not recomend it long term as the thermal load would be unbalanced as well this may cause heat damage.

I've read this three times, and I think I understand the question. You have two tops at 8ohms, and one sub at 8ohms. You are asking can you run it with 8ohms one side, and two parallel 8's the other which gives four? :confused:

My hesitant answer is yes, subject to the next questions, but I would advise getting another matching sub, so everything is in balance. Is your sub fitted with an internal crossover? ( ie sockets marked in/hi out ) Is it 4ohms or 8ohms, which will affect the answer?

My ensuing suggestions would be active crossover, and second amp.

Yes, it should be fine.

On my old system, I had a load of 8 ohms on one channel, and 4 ohms on the other.

Thanks for your advice; I’ve got two tops each at 8ohms and one 8-ohm sub, the sub has an internal crossover.
I think I will have to look into getting a second sub, yet another thing to squeeze into the car and trailer!! :D

Can of worms time, if you're using the internal crossover to feed your top from the sub, then it's generally accepted that you are running at the impedance of the sub, and not linking them in parallel. I'd still recommend another sub though. ;)

Cant see a problem with mixing the load, Years ago when i were a lad, we often did exactly that although it was with bass bins.
Crossover to left channel set at 80 - 120 & right channel 110 - 190
six ohm one side 4 another

we run a single sub off just one side of a numark dimension 3. No problems so far!! single sub gives more than enough bass (its a 500W/1000Wpeak cerwin vega sub15). We tried the amp bridged, but had much more tendency to clip. the dimension 3 is 475W into 4ohms/channel so quite well matched. crossover is inside our mixer. The amp we use for bass is also our backup amp if the main fails.
