I didn't want to cause any confusion because of RF7 Original and RF7 Classic. I didnt knew that. This is definitely the RF7 Classic Crossover.

 

RF7 X-Over are shown in the link above mentioned

OK, can you fellow members confirm if these are correct:

 

RF-7 I Crossover:

RF-7 CLASSIC Crossover:

Excluding the DCR values because Deang mentions somewhere that they may be wrong.

 

The most important thing is to distinguish between the I and the classic.

@MechEngVic I have never dealt with these two X-overs in detail before, so I don't want to take a position on them. But after comparing the image of the RF7 Classic X-over this could be possible, but the RF7 Origin , No Idea , why don´t you have a look there ?

OK, I think I figured it out. The RF-7 I has a round binding post cup, and the RF-7 Classic binding post cup is square.

The round one has the double layered crossover (more components), and the square one is the single layered one (fewer components, all visible, matches simpler schematic). So that means that the schematic designations are correct. Now if I could just get confirmation on the values.... @InVeNtOr ???

The have the same number of components and values. 
 

The schematic shown as Rf-7 I, is actually the RC-7.

OOOOOHHHHHH, OK. Thank you Deang. I will correct accordingly.

So here's the final word on RF-7 I vs. RF-7 Classic and their crossover setups:

 

RF-7 I and RF-7 Classic have the same schematic:

But the two speaker's binding post cups and crossovers have different physical formats:

If this is a professional, why in the world did he install the horn the wrong way round ?  60 x 90 degrees angle. I just thought I had hallucinations, so I'm going to put in a picture that shows the correct 90 x 60 degree angle of the horn.  The reason "why" is not clear to me from the video and is also not mentioned

The most interesting aspect in this video is the approach of the two and a half way design at the crossover.However, this would only make sense if the second woofer was separated from the cabinet by an additional intermediate plate, as in the MK III.

@Deang  I don't know if you have already watched the video, I would be very interested in your personal opinion about the two and a half way version of the MK II. Does that make sense?

As long as we are on subject here has anyone built bases for the RF7 to tilt them back several degrees? Kinda like the bases for the 280f?

@Robert Olson  You are not supposed to do that because the radiation angle of the 90 x 60 degree horn is different from that of the RP280F . Alternatively you can also get these absorber feet . Installation is easy . The radiation angle from the RF7 won´t be changed

No my friend ...LOL

 

Unscrew the angled plastic floor absorbers from the base plate and screw the ones from Dynavox into the screw hole of the base plate, that's all, you leave everything else out.

Understand that what I was asking was use the rubber bumpers over spikes ? I would think the spikes give better isolation

What kind of underground do you have, carpet? Parquet ? or stone floor ?

@Robert Olson  I just saw your setup in the Thread Hometheatre, you have a thin carpet. You should place the speakers with the Dynavox absorbers either on a Granite plate or on a bamboo wood plate. This is the best way to decouple the sound, and you can do the same with RP280F. The whole sound image will gain in precision, the bass will also be more precise
