Default ff125wk vs w4-1337sdf (ferite)

what ya think ?

Tang Band W4-1337SDF 4" Titanium Full Range Speaker 264-916

I may be able to build a 9 driver focused array, but I'm on fence over which driver.

To me, with a circuit for above 7khz, the titanium should be more electrostatic in sound. Then again, the ff125wk has received some praise lately.

Regarding Tang Band there seems to be quite a bit of resonance between 10kHz and 20kHz, depending on what your hearing is like you might need a notch
Almost 15dB spike at 15kHz

Looks like the list increased rapidly.

John Krutke (Zaph) rates the 1337 generally, including for FR use if notched above 10KHz, despite the so-so HD. YMMV on that score; the pair I heard were decent though I'd agree with John's conclusions.

The 125 is good; beats the old 127 & 125, nicely balanced & easy to work with. Less linear travel than the TB, but Fostex units tend to overload in a reasonably benign fashion, so I probably wouldn't put that as a heart-breaker; shallower profile cone than the TB, so slightly better off-axis. If you're concerned about materials, remember the top end of the Fostex is largely from the (metal) dustcap attached to the VC, so there's the metal you want still in place.

The 315 is a different ballgame given it's a much smaller driver. Usual tradeoffs for a smaller driver; it won't go as low. OTOH, it's about half the price, so you could buy more & Eq the bottom end if you felt so inclined. For the same money as 9 x 1337, you could get 16 x 315s. Personally I'd use a straight column with the 315s though rather than a focused array, assuming nearfield listening.

I've chosen the titanium (with notch) due to the comments on its detailed sound. I'm looking for electrostatic clarity.

Based on my success of 4 x 4" focused array, I've moved and now need more intelligibility at low volumes. The 1052 is poly (yuck to my ears) and I've seen not so pretty graphs, but I like the stiffening ribs ideas.

like this, but with 9 x 4", not the 16 x 3".

I'm hoping for fonken box in the fall for the 125wk's.

You probably need electrostatics if you want 'electrostatic clarity.' However, I suspect you'll like the TB.

FWIW, you might want to have a quick look at the most recent MA CHR-70, which has a similar response curve & is also cheaper. Off hand, I can't think of any other quality metal cone alternatives of ~these dimensions.

I have a pair of the ff105wk the 4 inch version and I have to say that I'm impressed. They are much smoother than the Fe127e while keeping the highs sounding crisp and really natural, without being harsh. There's no annoying accentuation of "ess" sounds; the highs are really nice on these. I've owned compact 2 ways that didn't have highs as good as this and mine have barely 100 hours on them. They're in cabinets that are way too small for them right now, so I can't really comment on bass, but what bass there is has enough substance to make me think they'd sound nice in a properly designed cabinet.

I have another pair of those just arrived... the 1st pair got scooped up before i could audition them.

I'm hoping it is a case of the smaller the better. FF85wk is fantastic, FF125wk is good but not without some issues that need dealing with. If 105wk is more towards the FF85 i'll be happy.
