Hello all,

This may sound like a repost, but I have generated some new qustions about my new (to me) BeoVox Conas. After Peter helped me sort the matter of cabling (2 pin din), I realized my BeoMaster 4500 has four speakerlink connections.

Since the BeoVox Cona has a dual voice coil, could I dedicate two of the speakerlink ports via the 2 pin din connections to each of my Conas? Would this be too much power?

Ultimately I would like to run both Conas on my BeoMaster in stereo.

Thank you as always.

I may have missed something here but why would you want to run 2 Conas???

Stereo bass. I was contemplating the same with my one Cona and my Beovox Pentas, but gave up looking for another one in white after a while. Having a right and left Cona next to the right and left speakers would solve the directional probs encountered by Cona users.

It's everyone's choice I suppose, but I'm struggling to understand this one also. Why stereo Conas?

When the reference was made to a 'dual voice coil', my first thought was that you wanted to wire up each of the 2 voice coils in each Cona separately, but I don't think that's what you mean!

As the bass frequencies from 2 subs would provide almost zero stereo imaging (the whole point of stereo) what you would really end up with is 2 subs giving the same output, but separated by distance.

A double sub setup is not that uncommon, but it totally depends on which speakers you will pair them with.

I did have 2 cona's and a similar setup (CX50 paired with a cona each) before I upgraded the speakers from cx50 to cx100. Besides having obviously more bass (from which the CX50's definately benefit), l did barely noticed the extra benefit in stereo image over just having one cona, ..... though my neighbours may not agree with me on that one  .....

However I cannot stress enough that placement of the cona definately plays an important role.

A cona with Pentas????

Just what do you listen to? Can't be any sort of music that I am used to!

Drum and bass :P

Well we obviously have very many different preferences haha. The aforementioned placement issue is a problem in my situation, very limited options. I am not really focusing on stereo imaging per say, I was just trying to describe the setup.

So any input on the original power question?

Well the amp contains only two power output stages, no matter how many speaker connectors there are or how many of them you use simultaneously. I didn't quite understand how you were planning to connect them, but whatever the details are, you will only get the same amount of total power out of the amp.

If you connect two Conas, the available power will be divided between them, and each one only gets half the power of what a single one would when connected normally (as you can only use one half of the dual voice coils). So the only advantage will be that the bass will come from two points in space. Also, remember that the two separate bass sources will create standing waves and dead spots depending on placement, listening position and frequency, so this might just as well end up being a disadvantage.

Or, did you mean that you would connect, say, the left Cona so that 1st input goes to speaker1-L and 2nd input to speaker2-L, and then the regular L speaker to the 1st output of the Cona? This would effectively attenuate the mid&treble of the main speakers, but I doubt (once again) that you'd gain anything you couldn't gain by just cranking up the bass setting of the amp. The knee point of this "dual Cona bass boost" will be lower though, so it is a bit difficult to tell if the effect would be good without actually trying. I personally wouldn't expect that to be very useful, but hey, you have the equipment, I don't...

Thanks Mika,

I fear I don't know enough about my Beomaster... please bear with me. So if I connect both of the left speakerlink connections to one of the conas, I will only get 55w total power?

That's right. The Beomaster has 2 x 55W in total (and it will not bridge over channels, so it will be strictly 55W max per channel), and you can't increase that with more (passive) speakers.

Thank you for your clarity Mika.

But if you do have the cabling or can build it - go ahead and try this and tell us how it worked! Just go easy on the volume; if you connect both Cona voice coils and a normal speaker on the same channel, the total load on the amp will probably be slightly more (or total impedance slightly less) than with two pairs of normal speakers connected.

Does anybody actually know what the Cona crossover is like? Does it consist of anything more than coils in series with the driver, i.e does it cut any of the bass off of the speakers that are run through it?

The basic output goes to cona where the lows are filtered out and fed to the woofer, the rest being sent on the speakers.
The speakers give less bass because of that. Mostly low to midrange and high. Works well together though.

Cona's have simple crossovers, basically a couple of caps and a coil per side. 

I will be doing all kinds of experiments now

Just to be on the safe side, if I run both channels to a single Cona, it could handle the 110w?

I will not be connecting any other speakers to my Conas. I just wanted some more bass. You will all probably think im bass hungry when I tell you I already have a pair of BeoLab 5000 panels connected via powerlink.

Both a single cona and the beomaster will have no problem.  Mine is doing just that for a couple of years now.

As I wrote before, position of the sub is key for best results.

Do not hesitate to try both cona's though for a short while and let us know what you think....  

Oh my thoughts will be prompt! As I said before the matter of cabling was sorted except for the aspect of where to get the little 2 pin din plugs. My dealer is closed (Again!), any suggestions on where to find them outside of ebay?

It may be different in the States but over here, any good (and even most not so good...) electronic components store will have them.

Try radio shack (If that still exists ?)

Good (audio) electronics repair centers should be able to get some I suppose

Radioshack is still around however I went to the website and found nothing. I even stopped into one of their stores near my house and the two people operating the store have never even seen a 2 pin din (had a pic on my phone). They directed me to Best Buy... (they have never even heard of B&O).

I probably have some if you want, will have a look around my stuff on the weekend.

There is plenty of companies selling these, just google it.

Cooldude,

I will try and find some locally first, if I cannot I will let you know.

One of the issues with Conas is that the cross over frequency is quite high and they are, to an extent, directional. Therefore the stereo idea is not daft. Not sure I would use them with Pentas as the frequency range will not be extended but each to his own. The Cona was very much designed to work with C/CX speakers as they cover the range 40 - 195 Hz, which removes a good chunk of bass from the CX allowing them to work better as well as adding quite a bit to the bottom of the range. A musical speaker but not an LFE one.
