If you look at exactly how he decides it "sounds so good", based on the room set up and the approach, I would not trust the way he hears things. What a disaster.
This is probably the very best example I have seen of a novice following all these rules of mysticism. Open baffle, 6 db/oct crossovers, etc. etc.

I have included the phase and impedance measurement of my mid-range section. I don't see the dip down to 5 ohms. I have no idea where you got that (?) CHECK THAT. The file is too big to upload here. I took a picture from the screen instead. Probably can't see much from it. Darn
You are right Scott: your driver's impedance doesn't fall as much as I had seen on the manufacturer's graph http://www.tb-speaker.com/uploads/fi...113e29b0a5.pdf

Interesting driver!

i dont know b&w fsts specs but here is no eq, no xo and same amp gain levels comparison

after eq i have to pad fst 5db down
FST is a great driver. I have them in my B&W and love them. They are rated at 94dB sensitivity, though, and low impedance. Impedance is low, but very flat. I remember someone measured this online. Excellent driver, but not for my application.

On the graph supplied by TB,
the db is scale is on the left, the impedance scale is on the right.

Since the very first time I heard this driver, I knew I wanted it. It just sounded "right". (and "right" is a personal subjective opinion)

yea just thinkin what sensitivity really is on those, there are 4-5 different fsts versions
measured that horn would not add any gain to 2k and tpl is 100db at 10k

i still have to -5 db fst

reason have to be that amp plays louder 3.4ohm speaker that it does 5.9ohm one?

Indeed. I must have looked at the wrong axis. So minimum impedance is about 8ohm.

Have you heard Lowthers? How do they sound different from your midrange?

Sadly enough, I have only heard one pair of Lowther's in my life time. It was back in the year 2004, in Austin Texas, and the sound quality was SUPERB.
If memory serves correct, they were DX-2's and mounted in ORIS 150's.

That, my friend, was a life altering audio experience and forever influenced what I wanted for myself.

It's been a long number of years ago, so I can't really compare. Both his and mine are superb. Tang Band gets a bad rap because they don't cost enough money for the snobs. AER and Voxativ no doubt, rank even higher than
superb.
I did hear some Voxativ at Axpona,Atlanta 2011, and have to say they were sublime (which ranks higher than superb)

Im getting good results with an 18sound 8NM610.
16 ohm rated impedance.
Very efficient. Very expensive unfortunately.
Designed to be horn loaded, but Im using it on the baffle.
Crossed at 2.4 kHz to TPL150 (no horn).

If it were me, I'd choose the 6ND 410, build my OWN back chamber and horn load this beast !!
