Near is within a few feet or so. Either on desk or stands. Not expecting reference levels. Just intimate elegance.

Markaudio has some really nice FR drivers at very reasonable prices. TangBand has some nice drivers, but 3x$ of MA. Fostex has lower XMAX higher prices. Probably good for low level nearfield.

Perhaps planet10 or others can chime in as they certainly have more experience than I with Fostex drivers, but the ones I've heard behave gracefully enough when pushed beyond Xmax. Sure, they won't do club-level bass-heavy techno in any kind of sustained manner, but they handle dynamically rich music quite well IMO. I listen daily to a pair of FF125K (see my avatar) with an almost non-existant Xmax of 0.15mm and they have no issue playing at satisfyingly loud levels near-field.

I am talking about these two drivers for example:
Tang Band W5-2143 5" Paper Cone Full Range Driver 8 Ohm - $51.90
Tang Band W6-2144 6-1/2" Paper Cone Full Range Driver 8 Ohm - $81.40

Are the MK drivers cheaper? I always thought they were more expensive.

I looked at lots of FR drivers on Parts Express and Madisound. Some use whizzer cones and phase plugs or cone profiles to give better HF dispersion. It's hard to choose. I want a compact sized enclosure so I need a driver that works in smaller Vb or Vc.

I had 4 of the MK CHBW-70s which had a plastic frame and did not seem sturdy to me. I ended up using them in my friend's synergy for his mancave.

I had 4 of the VWR126X drivers in an OB and I found them pretty impressive for the mid-range. Build quality was quite good.

I have had a fair amount of drivers (yes, I do have a problem) and I am very impressed with the TangBand build quality and capabilities for the money.

I like the plastic baskets… less ringing compared to aluminum or steel. One does need to be careful with the screws (but that is the case with all drivers — too tight is not good). The new Pluvia baskets improve the tech.

The CHBW is really a midbass… the top end is purposely shelved down about 15 dB at 5kHz.

My two cents:


I never heard and know nothing about the CSS FR125S, so please read my comments in light of that fact. I own and have directly compared these drivers to each other: Tang Band W8-1808, W5-1611, W5-2143, Markaudio Alpair 10P, Alpair 10 Gen. 2. I have tested them both on a 48" X 48" baffle and in a variety of cabinets, all within one meter listening distance. Since the W8-1808 is an 8" driver and requires a fairly large cabinet, I think we can discount that one for your stated usage.


All of these drivers produce what I would call acceptable sound quality, but my favorite, the one I think has the best tonal balance both on and off axis, is the Tang Band W5-2143. It models well in a small bass reflex cabinet, but the limited Xmax restricts the bass output. If you can live with that limitation you will be rewarded with a driver that produces a smooth and detailed sound that is equally superb at both lower and higher volume levels.

Steve - for that close a listening distance, I'd suggest either the Alpair6P, or Fostex FF85WK. The latter is a bit more forward and dynamic in the mids, but in a nearfield application punches way above its weight class. I run a pair very compact pair of boxes with little Topping TP30 amp .

I've heard the FR125, and as Dave noted earlier, it was a helluva driver 10yrs ago, but there's more from which to choose these days. Of course there'll be lots of other suggestions - careful what you ask for, analysis paralysis is almost guaranteed at least once in a while .
