WTB: FE127 or similar?

[zmix]

I had an amplifier mishap that damaged one of my Fostex FE127 drivers.. Sadly these are out of production now.

I'd like to find a replacement or two, short of that perhaps a recommended replacement?

FX120 is the closest, just the frame is a little different shape, but the hole pattern is the same. Motor is bigger in diameter.

What box did you build?

Thanks for the reply Jeff.. actually looking for a pair of FX120 as we speak..! The cabinet I'm using for the 127s are actually a modified pre-built Yamaha cabinet.. ($0.00) and I am driving the speakers with a current source. They're my 5th set of reference monitors in my studio...

Maybe this one is even a closer match? Looks like it will work in a ported box.

Jeff, FF125wk is going to need a smaller box. Same curve for my boxes gives me 9 litres from 13 for the FE127. It is, i believe, going to prove itself a better driver.

This looks like a pretty amazing driver for the money, too:

Any idea what the int. volume is?

Cheap 1/2" yamaha-wood cabinets... exterior dimensions 8"x7"x13".. 2" port 6" long..

~= 8.26L^3 (0.292ft^3)

FF125WK looks pretty good in those Yam. boxes, much better than FE127's. F3 is 60Hz, vs 75Hz for the 127 with the same tuning.

You'll want a bigger box for the FX120's, if you decide to go there.

I've been veering towards this group of drivers as possible candidates:

Tang Band W4-1337SD 4" Titanium Driver 264-848 $74

Specifications: • Power handling: 25 watts RMS/50 watts max • VCdia: 1" • Znom: 8 ohms • Re: 6.8 ohms • Frequency range: 70-20,000 Hz • Fs: 70 Hz • SPL: 87 dB 1W/1m • Vas: 0.17 cu. ft. • Qms: 1.51 • Qes: 0.49 • Qts: 0.37 • Xmax: 3 mm • Dimensions: Overall diameter: 4-15/16", Cutout diameter: 3-3/4", Depth: 2-7/8".

It's titanium, but the published measurement shows no breakup modes in the mids... the "recommended" enclosure / port is very close to my existing box. ("This functions best in a 0.25 cubic foot enclosure with a 2" diameter port that is 6" long. That would yield an F3 of 70 Hz")

....their bamboo cousins:

Tang Band W4-1320SIF 4" Bamboo Full Range Speaker 264-914 $38

One ferrite, one neodymium...


But the curious one is this, it seems really good on paper:

My goals are: narrow dispersion, reasonable bass, good articulation and presence.

My questions are : Titanium? Phase plugs? Bamboo?
