Fullrange studio monitor

Hello guys,
I won't repeat the whole story, please read my questions in here:

I just browsed briefly. I have been asked to design a small desktop active speakers for desktop mixing, and within a predefined cost. I have sorted to a 3" full range as a solution since the sonic qualities was deemed quite acceptable, until somthing of a larger size with the same quality and price range can be found.

We did some comparison with a pair of roland two way active speakers with a 5" bass, our 3" design actually had better tone balance in the low end. Cleaner sound and more precise.

The key issues are:
1. Tone balance
2. Free of cone resonances

Most full range drivers will tend to ring a bit longer in the higer frequencies because most of the time these drivers rely on cone resonance to extend the frequency. When designed as such, mixing becomes difficult because one does not know how much reverb etc. is the proper amoung, and tone balance may not come out correctly. Small cones have cavity resonances to look out for. So what I'm trying to say is that studio monitors really do have different contraints and priorities than normal audio speakers.

Adam,

does this meet any of the requirements?


Jordan JX92S in a small enclosure

By-the-bye, one of the criticisms of the enclosure is the MDF squeak; in exasperation I threw the fake-fur rug over one - the improvement is very pleasing. Now working out the best way to get the same effect and let the cat have her rug back.

Personally, though there are some very nice single driver boxes out there, I wouldn't use them for a mixing reference, they are so different to just about every speaker out there that they could give misleading results.

What about Manger and ATD Hypergraph 170Ti with 12dB x-over at 300 Hz? In my eyes the only flaw of the Manger is that it is not capable of doing very high SPL, which is not so crucial in a nearfield setup.

I am drawn towards Supravoxes at the moment, but it does sound like it should be something cheaper ... these are quite interesting, and might be good for nearfield monitor

New small ones complete with plans and measurements

Well I suppose that using a single driver monitor is going towards the "****box" concept other then the only monitor to rely on, but regarding this, 1 driver shitboxes like Auratones (and now MixCubes) are used efficiently to check on mixes for real world translation issues, remember that many consumer audio stereos are single driver. The MixCubes doesn't suppose to sound **** but just limited bandwidth which is critical and has no XO in it, and I guess that this is a good goal with this fullrange design. I guess I'll keep my ANF-10 as they are doing an adaquate job, and I'll complement them with either MixCubes or something I'll build. The MixCubes were developed for quite a while for this purpose and cost $200 and I wonder if building something else worth the trouble of not being satisfied for the result as a professional tool. Anyway it makes sense to invest very little money in a DIY speaker for now. I have the woods, tools etc, the cost is just a few more bucks then just the drivers(-:

Jordan is too expensive (-:

Don't know what you are talking about... (-:

Ohhhhh very nice stuff, whether I build it or not, nice to see small TL's.

If Jordan is already too expensive, better forget it.

Cery close nearfield will always present problems with a crossover and ought to be designed especially for this task, though a coax driver deals with some of the related problems
