Dayton Audio RS52AN-8 2" Dome Midrange
Does the RS52AN-8 require it's own sealed enclosure or does the plastic cup on its rear side mean that I can install it direct into the bass enclosure? I want to use it in a 3 way system
The rear of this driver is sealed so it does not require its own chamber.

If I wanted to run these all the way up in frequency is there anything I can due to attenuate the nasty spike in amplitude that's present around 12 to 13K hertz using passive crossover parts? (coils, caps and or resistors)
What you are looking for is called a notch filter [or a narrow band pass filter] if the spike is wide. A 0.15 mh coil and a 1.5 uf capacitor will attenuate the spike but this is a 12db per octave slant--not a true notch. Check with PE's crossover component values or building loudspeakers charts/graphs section. There you will find exact filter specs. At 10Khz there is a lot of wiggle room for the values of these parts.

What type crossover?
I am planning on using these in a DIY speaker build in between a pair of Dayton 7" drivers 40-2200Hz, and a Vifa Tweeter 1500-40000Hz. I was thinking of crossing at 750Hz and 6000Hz. What order crossover would work? Do I need a second order, or can I get away with a first order crossover for this? Is this even a good plan?
Normally in a 3 way you want to cross your woofers lower, and your tweeter higher. The way you have it planned all of your speakers would be covering the range of human voices, and that is not a good thing. You want to allow each section to cover the frequencies that they handle best. Crossing your mid over at 700 and 6k is not a bad plan, but you want to keep your woofers and tweeter out of that range a little more.Since each driver produces sound beyond the crossover point, there is constructive interference between the speakers over a broad range. The order of your crossover and the natural roll off of the drivers determine how broad that range is. Knowing this, you may want to leave some space between the crossover points to prevent that constructive interference from making the complete speaker louder around those points. So, maybe something like crossing your woofer over at 500 Hz, your mid in at 700 Hz, your mid out at 6 kHz, and your tweeter in at 7 kHz, would allow your finished speaker to perform at a uniform volume across it's full range. Mind you, this is just an example, not a suggestion.If you want to really nail down how to make this speaker sound good, I suggest looking into some modeling software. Check out the Tech Talk forum for some good threads on how to do this.If you plan on just doing this by ear, I would suggest that you use 1st order crossovers to save on material costs, as you will probably need to make serious revisions to your design them to sound good.

What is the units Xmax, Xmag or ....
what is the Xmax or Xmag (82% BL)? If that is not availalbe, what is the VC length and the height of the gap?
Unfortunately we do not have any of this information available.

I've read the various threads in the TechTalk Forum and the other questions and reviews here. I intend to use these in a car door, actively crossed where it is happy, around 800Hz and 5KHz give or take. My question is does this driver need any additional passive attenuation or notch filtering in this frequency range or is it smooth enough as is? I could also lower the low pass point to avoid any nastiness around the 5KHz point.
The natural response of the driver is very smooth however this is on a flat infinite baffle so this will change once installed in a car so it will still need to be tweaked by ear after final installation. The crossover points you have listed are fine and using active crossovers you should have a steep enough slope to get rid of the breakup issues above 10k.

Your thoughs on using RS52AN in a line array
I just thought about using 4 of these to create a line array. I would connect them in parallel, then series so that the impedance would be 8 ohms. Has anyone tried creating line arrays with this driver? Would 4 drivers be too much? Other components to be decided but each enclosure will have 2 10" drivers, and 2 or 4 tweeters.
Great choice. Very wide response range. However, the faceplate can be removed/replaced to minimize the driver spacing but it is still much wider than the more expensive CAM 558 MD55's which can be modified to 3" spacing. Their response is not quite as wide as the RS52 but it is a silk dome instead of alum. I ground down the plastic faceplates to minimize the spacing. I wish Dayton would release a dome like the Morel's just for this purpose.
