Go to 8" and 10" data.

Dayton RS 7"  Non-linear Distortion Data:  100% amplitude modulation @ 10% of fundamental.

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

1 KHz	2 KHz	3 KHz

Dayton RS 7" Stored Energy Data:

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

Stored energy doesn't get really bad until about 2400 Hz on the 7".   Non-linear distortion is also very low.  A lot of the little spikes you see that look like higher harmonics are probably not real.  There was a lot of wind today blowing on the microphone so I believe that's what caused this.  Note that these spikes do not have side bands like the fundamental frequency and it's usual harmonics. 

For comparison, let's look at the Peerless 6.5" 

Peerless 850467 6.5" HDS  Non-linear Distortion Data:  100% amplitude modulation @ 10% of fundamental.

40 Hz		80 Hz	100 Hz	200 Hz	300 Hz	400 Hz	600 Hz
1 KHz	2 KHz	3 KHz

 Peerless 850467 6.5" HDS  Stored Energy Data:

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

The Peerless seems to be a really good driver.  It has better stored energy performance than the Seas 8" and the non-linear distortion is also still really good with the exception of some high 3rd harmonic content at low frequency.   This would definitely be a great driver for 80 ~ 100 Hz to above 2 KHz.

Dayton RS 6"  Non-linear Distortion Data:  100% amplitude modulation @ 10% of fundamental.

80 Hz	100 Hz	200 Hz	300 Hz	400 Hz	600 Hz	1 KHz	2 KHz
3 KHz

Dayton RS 6" Stored Energy Data:

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

The 6" RS turns out to be another great driver.  Stored energy of course starts to look pretty nasty above 2 KHz but that's ok, there are plenty of tweeters that can cross-over that low.

Dayton RS 5"  Non-linear Distortion Data:  100% amplitude modulation @ 10% of fundamental.

80 Hz	100 Hz	200 Hz	300 Hz	400 Hz	600 Hz	1 KHz	2 KHz
3 KHz

Dayton RS 5" Stored Energy Data:

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

The third harmonic is a little high at 80 Hz but this is a really small driver with a cone smaller than some 4.5" drivers.  These measurements were made with 5 vrms measured at the speaker using a Fluke Scope meter.  The actual peak is much higher due to the modulated tone so the poor little tiny cone was pumping really hard for the 80 Hz measurement.   So, all things considered this is pretty good.

Go to 8" and 10" data.
