Default Home Cinema with full range

IMO...
Line array full range speakers are fab for home cinema.

But for real home cinema you are always going to need at least one sub, better with two or even three, corner loaded, sealed 60 litre to 70 litre 20mm to 25mm birch ply or 10mm alloy.
Try a 12 inch Beyma 12SW 1300Nd with 500 watts minimum and a bit of room Eq and you will be in heaven!

I agree with Norman on the point of using identical drivers all round.
I use 16 BMR drivers per side in line arrays for my front left right, 9 BMR's for the centre channel, and 4 BMR's per side at the rear.
Seamless seamless, seamless, really great effects on movies and lovely with music too.

Cheers
Derek.

I contacted a French compagny for the Beyma 5CX200NDNE they are available 181Ђ each (transport included), this is still expensive for my project, even if the price seems very good compared to other sellers.
then remains the Fostex (FF or Sigma) & Mark Audio (CHR 70 or Alpair 12) although quite difficult to find a reseller in France (do guys knows one?).
Well, the Beymas -while not cheap- are inline with your original budget, for the front 3 channels at least, a bit above for the rear channels.
I still find these a very interesting choice for a good quality home cinema, more realistic than a fullrange solution (and I do like FR drivers, for music that is). The main reasons being that they will be near indestructible in a home cinema setting yet (likely, I haven't heard these) still offer very good quality for music use, and they have much better off axis dispersion than FR drivers which is pleasant when multiple people watch a movie.

the worth with the Beyma is that there is no feedbacks nor builds already done with them, or at least i did not find them

I found a russian site with filter and box design for it. And, for what it is worth, it had an award during a professional trade show.
From my experience with the brand, the sound is likely very good.

Great looking speakers (and daughter (?) btw).
Q. With all the driver coils - Don't they act like a inductor and attenuate the treble?

Default Multiple driver inductance

Hi Doug,

Thanks, yes my daughter is a real cute kid, her twin brothers are cool dudes too...Going to be a bit crazy round here when they are all teenagers...Gulp!

Re driver inductance, basically its not a problem, in fact using multiple drivers gives you a much cleaner and more open top end ( and midrange too).
It sounds even more extended than a single driver, but measurements show no real difference, only tiny plus or minus driver tolerance variance.

The reason the mid and top sound way better than a single driver is that the each cone in the multiple driver speaker is only moving a fraction ( a sixteenth in this case) as much as a single driver cone would for the same SPL.
This basically eliminates all the problems that single full range drivers have such as : no percussive impact, no bass, high distortion at any decent volume, confused and muddled sound with complex music...etc. etc.

Traditional line arrays have their own problems, esp. two or three way arrays using separate lines of tweeters, bass mids and or woofers. The crossovers can be a real nightmare, and both horizontal and vertical interference can be problematic as well as off axis lobes and rear wall bounce.
Also fake or " mini arrays" i.e. 3 or 4 feet lines of drivers which are the worst of all worlds, wont bore you here but suffice to say you are better off with a good old 3 way rather than a pint sized array.

Hope this helps and all the best
Derek.

Here: Динамик широкополосный Beyma 5CX200Nd, обзор. Портал "www.marvel-pro.ru".

Many pictures of the speaker itself which looks like a serious piece of kit.

google translate can help.

After a long reflexion and budget re-evaluation, i think i'll go with the Beyma drivers.
and so now, final reflexion:
the three models are 5CX200ND , 6CX200ND & 8CX300ND, where the first number is the diameter, and the price is approximately 210€, 220€ & 240€ before negociation, (note that a company was decreasing the price for 5 5CX200ND to 181€ each, transport included)
so the question is the following: which configuration
- 5 (front + center + rear) 5CX200ND or 6CX200ND or 8CX300ND + a Sub (a previously mentionned)
- or 2 Front 8CX300ND + Center 6CX200ND + 2 rear 5CX200ND + a Sub (in order to have better sound in HC & Stereo Hifi)
- or 3 (Front + Center) 6CX200ND or 8CX300ND + 2 rear 5CX200ND + a Sub (in order to have better sound in HC & Stereo Hifi)
