Default Full range minimonitor

Looking for a 4" fullrange driver. Which ones are worth considering, performance is more important than price. Low motor ditortion as well as decent conebehaviour of course.

These will be used for PC game, small hometheater and possibly even hifi if the result turns out good enough. Main criteria is big good sound in a small package as far as physics allow. 3-6 liter reflex box would be nice.

Jordan or Tangband?

Thanks in advance

/Peter

Hi,
You might wanna build something like Jim Griffins mini-monitor with the Jordan JX-92S which is about 7l.
Exterior dimensions are 12.5H x 7.5W x 8D and walls are 0,75" thick.

Thanks Ill have a look. 7 lit is a little more than I had in mind though and would probably go with a potent European 5" two way in such a volume.

I build the solo 103s and am very pleased with the result.
Do not expect very high SPL though. It is sparkling and really nice for acoustical music reproduction.

I'll second the Solo 103's. And the bass reflex design is going to get you the best bass response possible in this small of a cabinet design.

I am really pleased with mine.

Default Fostex FE103E vs. Jordan JX92S

Any use of the FE103E in a vented box is a criminal act at best. Using the Fostex 103 in a vented box is a speaker that I would not recommend. It has Xmax= 0.35 mm, 5 watts rated power handling, and Fs of 80 Hz. In a 7 liter vented box you exceed its Xmax around 350 Hz with that 5 watts input. You have to like mid-range with this driver because it does not do bass, midbass, or far bass for that matter. Output SPL will be so low you'll have to use it nearfield or real close in my opinion.

In contrast the JX92S is rated at Xmax of 4.5 mm, 50 watts power handling, and Fs of 45 Hz. It works nicely down to an F3 of less than 60 Hz in a 7 liters box. It will do safely do bass without exceeding its Xmax at 50 watts and produce decent SPL while doing so.

The little Fostex needs a back horn or such enclosure and even then you need to be happy without any real bass impact. Bottom line: The JX92S kicks the FE103E back to Japan with more bass output in a small vented box.

Jim

You can go as small as 4.5 L (actually smaller) with Jordan 92
which equates fairly closely with the size of the Eikos Speaker
I prefer around 6.0 L
If you want really small like 1.0 / 1.5 L but really high quality & bearing in mind you will envitably progress to a sub at some stage may as well bite the bullet & try the Jordan 53's with a small sub (or two)

Make things easy for yourself & use sealed

If your reasons / concerns are for a small discrete unobtrusive speaker you can try mounting just above the desk with rest of enclosure below desk. In which case you can have any size you want. Have Fun.

I'm building a couple of TangBand 1052sa's into 7 liter bass reflex boxes (right now they're in bass reflex cardboard boxes for prototyping - I'll start the wooden ones this weekend). Good full-range response and bass extension to around 65Hz anechoic. They have neo magnet motors, too, so they're essentially self-sheilded for use near a CRT. I did MarkMck's cone and pre-filtering mods, and so far the performance is quite impressive.

Put on the cuffs, officer. It's a fair pinch.

0.35mm is tweeter territory so that one is out of the option.

The Jordan seems like a lot of fun (both of them) and will be considered. I will check those Tangbands out as well.

BTW whats the cost of the Tangband 1052?

Thanks for all the replies.
