First I'd like to say thank you to cheapboy for such great information and knowledge he shares via his testing and expertise in this forum.
I have the 9845c's from Zalytron, picked'm up for $45/pop. I removed the backing and threw them IB in my OEM kicks replacing some cheapo Peerless 2 "domes. Its a pretty confined kick area in terms of surface and seal- but has a few inches of airspace behind it, lined the back with polyfill. The kicks were rather flimsy after cutting out a larger opening to seat these, so in turn were carpeted in the exterior and reinforced behind them with some mat deadner-pretty sturdy now.
This driver as stated is very open sounding, and has been nothing but a pleasant upgrade. They mate well with my dynamic, lively Rainbow tweets. Whereas the Peerless they replaced were more muffled, uninviting in sound and thus the tweeters were the focus of attention due to their detail. While wiring around under neath the carpet in the pasenger footwell, i was listening to them and as i i turned them on/off axis away from me there is a very minute in every sense of the word, hardly worth mentioning difference- their off axis and overall dispersion is quite amazing. They stage well with little work.
They definitely added more dynamics to my fronstage as i quickly noticed upon listening to a trumpet quartet in one of the Focal tracks...the whole body of sound of the trumpets filled my cabin and was felt like never before-airy,vocal range also became more centered and pronounced-those backround vocals also increased in clarity, less breathiness.
The Peerless tonally were just not a good match. The clarity and pluck of bass is so much more refined now, and on the piano tracks of the Alpine F1 disk the lower piano parts exhibited more a higher and more realistic attack.
I have them at 500hz on a 24db slope to ~3.15k 6db slope. I've had them at 4k and 5k on first to second order slopes, but i think due to the arrangement of all my drivers-due to staging preferences they sound best at this xover point in my car. Currently my stage appears to be about 4" into the edge of the dash. By moving my tweeters forward into the sails (about 6" or so,AND 2" HIGHER) as soon as I can get a hold of some new door panels, i feel i can push the stage back to a more desirable point.
Like most DIY drivers thery came in a simple box, no literature. So other than cheapboy's review of the (9845M i dont know anything solid on them). They do have a very nice feel for them, strong grill. I didn't get a chance to listen to them with the plastic membrane on, first thing I did when I received them was remove them and surprisingly theres not much depth to these, smaller motor than the Peerless by a almost an inch mounting depth difference.
The positive and negative terminals are marked on the plastic backing itself, so note to keep this in mind to mark it on the magnet with say a sharpie upon removing it.
