My latest system upgrade.
Thank you very much Rick.

Lovely speakers, Mark. Wish I had a bigger room like yours.

All you need now is a C4 in matching oak (cough viewtopic.php?f=29&t=6630&p=34265#p34265!)

So ... how's it sounding?

Hi Mark, great system. The new speakers look superb, bet they sound terrific.

:D Enjoy

Thanks.
The speakers sound fantastic. Kids love them. But I can't quite get the sound stage that I had with the SCM40's, so I have a bit of positioning to sort out. I have also connected up a new Cyrus Stream X Signature. Apparantly, according to the Cyrus instruction the Stream needs a lot of time to burn in. ie 3 days of solid running. I don't know if this is snake oil or if that is correct (perhaps someone can let me know?). But the music does sound thinner and a bit less bassier than through the old streamer, though the instruments do sound clearer and sharper. Massive Attack sounds amazing but Guns 'n Roses sounds crap. Perhaps that's not really fair to say as I have only listened to 2 tracks.

Hey Mark can we see the tweeters - would you dare to remove the covers and expose them?

Hi Shardone

Indeed, the new Super SH25-76S tweeter does look awesome :)

Not sure whether you've seen this but -

Technical data for ATC's new Super SH25-76S Soft Dome Tweeter

The SH25-76S is ATC's premium 25mm soft dome tweeter, designed and built with the same no compromise philosophy as all other ATC drive units and to perfectly compliment the renowned SM-75-150S Super Dome mid-range driver.

Unlike almost any other 25mm tweeter on the market the SH-25-76S is a dual suspension design which ensures pistonic motion, suppressing anhramonic rocking mode, even at high drive level, and enables the use of narrower magnetic gaps, this, along with a short coil, long gap configuration ensures unparalled lineraity and incredibly low distortion throughout its intended operating band. The soft dome diaphragm is based on a complex geometry which maximises power transfer from the former, extending the high frequency response and giving a smooth off-axis response.

The massive neodymium motor with heat treated top plate is optimised to give a 20,000 gauss (2.0 Tesla) in the magnetic gap, extending the frequency response well beyond 20kHz and resulting in moderately high sensitivity, even with the very strong, well-damped structures employed. The huge motor assembly also performs the secondary function of dissipating heat away from the coil and ensuring high power handling and low power compression. The motor topology and moving assembly design negate the requirement for ferro fluid. The SH25-76S is therefore, free from the detrimental effects of this drying out over time.

The geometery of the waveguide is designed for optimum dispersion and an extended on-axis frequency response. It is made from a precision machined alloy so that the entire structure is extremely rigid and free from resonances.

Specification-

Sensitivity: 91.5 +/- 0.5dB/W @ 1m

Nominal Impedance: 6 ohms

Frequency Lineraity (+/- 2dB): 1.5kHz to 22kHz

Cut-Off Frequency (-6dB): 26kHz

Dispersion: +/-80 degrees Coherent

Magnetic Gap Height: 3.0mm

Coil Length: 2.0mm

Magnetic Gap Flux Density: 2.0 Tesla/20,000 Gauss

Weight: 0.34kg

All the best

Are these upgrade tweeters ?

Mine have only 3 screws on the outer perimeter

Dogill,

I think only the new SE models will get the new baffle with the smaller tweeter cut out & three screws. New pro models and new standard models get a larger flange that fits on the new tweeter to fit the existing baffle where the old excel milenium tweeter fits.

At least that is what I figured out once Mark exposed his tweeters.... Thank you Mark!

Hi

Congrats for the speakers! I would love to get a pair like these one day. :D
If you want to get better soundstage, you should try moving them around 1,5 meter away from rear wall. Try to set your listening distance in a equilateral triangle from both speakers. That is how I would start.

Regards
Z
