Conjoined CX50s.. would this work, or does this sound a bit bonkers?

Hi, I'm new here, and I'd like some advice please.. I have just purchased and restored re-foamed and re-fretted 2x CX50s and 2xCX100s, and I really love em.. I'm thinking about another 2x CX50s laying sidewards tweeter-to-tweeter (bottom-to-bottom) to create a large centre speaker; that way I can also put the TV on top.. does anyone have any advice for a novice on how to use 2x CX50s as one centre channel? I was thinking I could do two lots of cables from one channel in a similar way to bi-wiring? would this work, or does this sound a bit bonkers?

Any advice help would be appreciated..

Well you get sound that way but the impedance of the speakers will double or halve depending on how you connect the wires to eachother.

So sound wise i don't know how it will end but you will get sound out of it.
you can also place 2 speakers and just connect one :)

Hi, thank you :) 

yes I guess I could connect just one:)) 

but if I tried to connect two, what would be result of doubling or halving the impedance?

I don't know exactly what happends inside, but if your amp is 8ohm and you use 16ohm speakers you only have half the power. 

But i think someone else can explain what will happen at the amp side. i only know it works :) and you can put speakers in serie or parallel to eachother resulting in 4 or 16 ohm (if you use 8 ohm speakers)

Thank you for your reply,

I'm wondering how to find out about this in layman's terminology?..

don't know if this helps: the owners manual for my Amp, says it has 'High-current capability, ultrawide-bandwidth amplifier design with low negative feedback' and centre channel is '85 watts from 20hz - 20khz @<0.05 THD driven into 8 Ohms'..

The BeoVox CX50s say 'Peak Power Handling 60 watt, Frequency Response 60 Hz - 20 kHz, Impedance 6 ohm' ??

any ideas?

 

Connect the 2 speakers to the centre channel in parallel, this will give you one 12 Ohm speaker. Your amp should be able to handle this without problem. It may sound a little too quiet though! Don't connect them in series unless your amp can handle a 3 Ohm speaker which it most certainly won't.

Other way around surely?  Connection in series will give 12 ohm.

Sorry yes of course Guy... in Series will give you 12 Ohm, parallel 3. Shouldn't post until I'm fully awake haha.

I would suggest only using one speaker for the center channel to reduce the chance of creating some odd lobing effects to the sound. The two speakers place so close together may produce some unwanted interference patterns.

Instead, I would suggest a single CX100 placed on it's side as a good solution. I have the surround system in my family room set up with 3 CX100s in the front and 2 CX50s as the rear surround speakers.

Thank you.. 

I've just tried the 2 x CX50s  that I bought as surrounds for the 1st time; I tried them in series as a double centre speaker 1st of all wiring them in series giving 12 ohms as Lee and Guy kindly little suggested, but they're not sounding too clever, even with the centre channel volume compensated for in relation to the others? I then tried just one CX50 in the centre which did sound a little bit better, but very thin.. I don't know whether this would be caused by the new foam surrounds that haven't been broken in yet, or could it be something else that I've noticed, that is to say the 2 pin males Din's on the CX 50s are the wrong way up when comparing them to the CX 100s?

Do you think that polarities will still be correct, or do you think the dash – is now positive, and the dot . is now negative?

Is this normal on the CX 50s?

Does anyone have any ideas please??
