Dayton RS 10"  Non-linear Distortion Data:  100% amplitude modulation @ 10% of fundamental.

40 Hz 60 Hz 80Hz 100 Hz 200 Hz 300 Hz 400 Hz 600 Hz

Dayton RS 10"  Stored Energy Data: 

400  Hz 600 Hz 800 Hz 1200 Hz 1400 Hz 1400 Hz Data 1600 Hz
1800 Hz 2000 Hz 2200 Hz 2400 Hz 2600 Hz 2800 Hz 3000 Hz

This is a pretty nice 10" driver.  Both the non-linear distortion and the stored energy are very reasonable as long as you use it in an appropriate frequency range for a 10".    Note that at 1200 Hz the stored energy is pretty bad.  At 1400 Hz I included the data so you can see the tone burst continuing to ring.  I really would not suggest using this driver even close to this frequency.   I would say about 600 Hz is more than high enough to cross-over to what ever midrange you would use with this.  This is definitely not a driver you would use in a two way but then what 10" would you use.   For 600 Hz down this should be a great performer.

The 8" looks like a great driver.  Yeah, there are some stored energy issues starting around 1400 Hz but it's -15 ~ -20 db down when it starts.  It would be nice if this wasn't there but it's really not that bad.  For comparison, let's see how it is compared to the Seas Magnesium cone driver used in the Orion.

Note that the Exce isn't all that great in the 1600 Hz to 2200 Hz range.  It seems to improve above that however.  It also looks cleaner in the non-linear distortion but you have to take a closer look.  These measurements were taken outdoors and it was really windy earlier today.  When the Seas was measured the winds had died down quite a bit so I suspect that a lot of those extra seemingly random spikes in a lot of the RS measurements are more likely caused by wind blowing on the microphone and or on the speaker cone causing random noise.  If you look at the groupings of the fundamental tone and it's side bands it seems the RS does almost as well if not as well on a lot of the non-linear test.

Go to my thoughts on the RS drivers.
