Hi all,
I am going to build some new enclosures for my Monitor Audio Vectors V10 and V20 speakers
I have 2 of the Vector V20 centre speakers and would like to combine them into one. Can I just wire them in parallel on the crossover or will I need to change some components?
Specifications of the speakers:

I have added the pictures of the Woofer, Tweeter and Crossover.
Thanks,
Mike.

The xover would need to change the values due to the different ohm load and if they were designed properly to start with changing the enclosure will effect it as well... pretty much need to completely redesign the xover.
For the amount of hassle your going to go through to redesign completely I dont think your going to gain much extra by doing this, Id sell what you have and invest in a better/bigger center speaker... may build a kit one or something if your keen on DIYíng it

You can halve the inductance and resistance values and double the capacitance.
The drivers will interact with each other, this can make unexpected changes.

Thanks for your replies guys. It seems it will be more of a ball ache trying to achieve what I want to do without having the correct testing equipment and knowing values etc. I have sent Monitor Audio an email to see what they say. They are pretty good at getting back with information as I have found in the past. I could probably wire both the speakers in parallel or series as my receiver can handle 4-16 ohms.
They probably couldn't have anything more useful to say.
The halving and doubling is exact enough that you can just go ahead and do it. It's the idea of running multiple tweeters and similar effects that are uncertain but I'm sure for the average person it's perfectly acceptable.
The real question might be what do you hope to achieve by this and is there a way to ensure that?

Why not make them work for you by going isobaric? Increased output, lower extension and better definition.
When you put the center speaker (in a 5.1 or more system) behind the projector screen (audio pass trough type) then the sound will come from the center of the screen (basically very close or like from the actor's mouth)
When watching the movie on a TV, obviously you can not put the center speaker in the center of the screen (where the source of the sound should be) so you put it above or below the TV. I guess many people are ok with that, I am not.
So what I am proposing to you s200bym is an alternative solution in which you take advantage of having 2 identical center speakers and place one above and one below the TV (or one left and one right near the TV might also work assuming the left and right speakers are far away from the TV; same height close to the middle of the screen, you aim left center speaker towards the right side of the couch and right center speaker towards the left side of the couch).
Applying the same signal to both speakers and the ear will do an average and the sound will be perceived as coming from the center of the screen.
You can still make new cabinets if you want to. You can either use 2 identical center channel amplifiers (preferable) or one more powerful amplifier connecting the 2 center speakers in parallel (if the amplifier has a minimum output impedance of 4 ohms or less) or in series and adjust the channel level to match other channels level.
Thank you for your replies.
I am looking at now running them in series as opposed to parallel. From my understanding, correct me if I am wrong. 16ohms is better than 4ohms as the amp doesn't have to work as hard. The receiver can run 4-16ohms.

Yes, lower current is usually lower distortion, IF you have sufficient voltage for the desired wattage.
Why do you want to do this in the first place? I can't imagine unless you were trying to fill a 50 seat theater you would need to do so. And if that is the case, just run them as is but use two amps.

To be honest the real reason I want to do this is so I don't have a speaker knocking about not being used (bit OCD). I want to make wooden enclosures instead of having the original plastic enclosures, so they look better and hopefully sound better. The wooden enclosures will have virtually the same internal volume so they will still be in design spec and shouldn't degrade the sound.
There is that I suppose. I built a custom wooden enclosure for the V20 centre a while ago (which sounded great). I spoke to one of the technical guys at Monitor Audio to get the internal volume so built it from that. I think it was 7.5 litres.
