Actually ordered 2 AMp6 basic sneaky's, ended up an ok price ~ $115aud total for 2 sneaky's delivered with insurance.

Thats sounding better!

I still can't get over how LOUD 15 watts is. I run 140w a DRIVER in my car, which can get loud, howeven taking into effect the efficiency of the drivers I chose (~95db) I guess it makes sense. As I said before, at 1/4 volume on the TA it is a VERY comfortable listening volume. Half volume is annoying.

Have you ever had a problem with the high's being a little recessed? Do the piezos maybe need to be broken in? I am thinking maybe they (piezo's) are a little less efficient than I thought, or the woofers are more sensitive than I calculated. I did use a 47ohm resistor for each piezo as you mentioned.

I have a calibrated mic that is 0.5db 20hz-20khz maybe I should use Room EQ and sine sweep for response.

You can try with a small resistor if you like but frankly I prefer it with a little lower highs. A smaller resistor won't give much extra output though. Just a little bit but it'll also make it more annoying when listening to acoustic or vocal music. A smaller resistor works best if you play mainly electronic music.

I am playing Norah Jones now and it sounds perfect. Good call, sibiliance isn't bad.

If it's measured indoors a frequency plot isn't pretty. Much better linearity when outdoors as intended. That's not to say that it flat by any hi-fi definition but it sounds remarkably well regardless. Then again, my Fostex FE206e which were used as reference in the design aren't flat either.

It's intended to to have really good bass performance (except for the really low bass which is missing completely although you most of the time forget that), and sound very natural on voices in particular and in the midrange in general. I am especially proud of the way it handles brass instruments and female voices which are notoriously difficult for a speaker to get right.

Yeah I was just surprised since I used different drivers. Here is the PDF plot of the FR from the manufacturer.

As I said, I am considering not even using the inductors I bought, it seems to roll off rather smoothly and sounds fine.

Bit stormy today, but had to test it outdoors. Loving a bit of 'Momentary lapse of reason'.
