Default Reccomand 3.5-4.5 inch widerange driver

Hi ,
Please reccomand decent 3.5-5 inch widerange driver to make good sounding small speakers.

Best if midrange sound natural but also if it get high freq trough well and midbass.
Probably not possible to get all freq trough single driver well but other option is use small tweeter for high and seperate midbass + crossover.
Also one idea could be to use car speaker kit if decent avalible.

Idea is to make closed box but inverter may also be added.

These Planet_10 mMar-Ken6peN's will probably never leave my desktop. These particular boxes were prototypes that have the wrong tuning. They are made from Baltic Birch ply, and have treated Mark Audio A6p drivers.

Click the image to open in full size.
Not bad freq response drivers and nice wood work(Those could look even better if darker paint).
If possible to get similar result with cheaper drivers id chose cheaper but if not possible then max build price ~130
Did you add damping also to walls inside? Are the ports below inverters?
Usually how does it affect sound in small closed type boxes if reducing literage alot via added damping material to walls.

I'm also a fan of Mark Audio drivers in Planet 10 enclosures. I have a pair of Mark Audio CHP-70's in slim golden ratio cabinets. I've played a round with several frull range drivers, but these are my favorite.

Interior is lined with 1/2" ultratouch denim.

It's a BR vented alignment.

If adding damping and thus reducing air portion in box, do i need to remove this air volume from the box when looking at driver datasheet reccomended volumes?

Some options are:
http://www.tb-speaker.com/uploads/fi...30744a549f.pdf
No angled responses and freq response look too linear, Could it be true?

http://www.seas.no/images/stories/pr...B-H1600-08.pdf
Drop on higher freq

http://www.madisoundspeakerstore.com...65WBAC25-4.pdf
It only 2 inch but it seem best prive vs freq response so far , but is freq response full truth on quality?

Without opening that same old can of worms on the subject of ultimate relevance of published FR curves, I'd posit they tell only part of the story.

Just to add another candidate to the list, I'd be negligent for not mentioning the Fostex FF85WK - when used within its limitations, this little guy can make a decent sounding desk-top system, or even as mid tweeter in a small 2-way. Cut from a different cloth than the A6P.

And while I'm just not a fanboy, there's the Vifa/Peerless TC9

How is sound of Fostex widerange drivers?
http://www.madisound.com/loudspeaker...ns/fe108ez.pdf
Spec sheet seems more trustable from Tang Bang as it has angled responses missing.

In the proper enclosure, Fostex drivers are very well regarded. If I'm not mistaken, they favor being in a horn configuration, so they might need a little more real estate than what you're looking for.

Enclosure for FE108ez
