Hi,
this is my first post. I'm writting from Spain and now I´m planning my second fullrange project . It´s an stereo speaker for my phone with two separated cabinets of 5.6lt each one.The ext. dimensions are 600x210x180mm The amp used is a TOPPING TP-20 MARKII.
I would used a pair of 4" or 4" 1/2 fullrange drivers , and if it´s possible vented cabinets .
The top budget for the drivers is about $100/$120 per pair
Some options I´m thinking are:
- Fostex Fe126En
- Tang Band W1611 SDF
- Every suggestions .....
Thank you in advance for your useful help and congratulations for this fastastic forum

I work with the Faitals in 3 inch and they are great drivers, good advice! They do need some low shelving filter though, and the same may be true for the 4 inch. This is the same as baffle step compensation, just higher up in frequence, and consists of a coil in parallel with a resistor. To get it right, you might need a measuring mike, which would including the drivers fit more or less in your budget.

I use the 3FE25 and 3FE22 - both excellent sounding and loud. They are not the prettiest drivers though so would benefit from rear mounting. For the BSC filter try a 0.8mH coil and 10ohm resistor.
One vote for FE126En. I love the sound of those drivers and IMO they are still unbeat from the lower mids and up in that pricerange. And with the right cab the bass, though not overpowering, can be very crisp and well defined.
While it prefers a horn a small BR can work too.
Fostex FE126E +
I really think it is a pity to use a tweeter with the 126 in the HF band as Troels did though, as it is really where it shines.
As you can see Troels cab is not far from yours in size.

PS. You could probably benefit from angeling the drivers out a few degrees to get better stereo separation, less overlap of the primary lopes and wider sweet spot.
Another thing: If you consider ever running the rig off a battery source, the 126's high efficiency will be a further benefit to using them.

I'm not so keen on the FE126s. Even with fairly serious cone treatments, they're still very bright and forward in the upper midrange. They need quite a lot of EQ to get them sounding level.
For battery use, I'd try to get 4ohm drivers - you'll get another 3dB at the expense of some battery life. A worthwhile trade, IMO - portable systems are always limited on SPL, but I've never made one that runs short on battery.

Well, thank You Chris. the speaker has no battery. it isn't a portable speaker.the idea is a speaker which the better sound as possible but portable inside home. I think,if the cabinet is sealed, no vented, a 5" fulldrive could work, but is only an idea after reading the enclosure recomended for some brands, like fostex.
Technical correction
Hi Guys,
Squeak comment, while interesting, is technically misleading, an over-simplification. I've adjusted several components (motor-sub assembly, cone, cap and coil) to produce the CHN's specific oscillation/resonance patten.
Observers will note that all my current 70mm diameter cone series drivers (CHN,CHP,R,S and Alpair 7) have the near same diameter cap (+/- 0.9mm) yet produce significantly different performances.
For those who wish to comment further on the issue of CHN cap sizing, please use the CHN introduction thread, so as not to throw this thread off-topic.

Hi Ben,
Thanks for your interest in the CHN. Its useful for many diy applications.
I try not to comment on this non-commercial open side of Diyaudio unless asked to do so. The Markaudio section is the best place where I and others could assist you in driver selection. I generally restrict myself on the open side of Diyaudio to dealing with driver function and operation issues.
Feel free to seek in-depth CHN advice on the Markaudio section. You could start a new thread there, or join an existing CHN or related thread.

Many thanks
Mark.
