Monitor Audio Gold 50 vs Studio 89

My take is that the 50 was truly designed as a surround speaker for a home theater set up.  Or a desktop setup. The 89 will perform more like a source point because of the MTM design. My dealer really tried to push the 89’s on me until I ponied up for the 100 6g. I was looking at upgrading my Kef ls50 and their next upgrade is the r3. Wanting to hear a ribbon tweeter, looked at Monitor Audio for an offering. 
you were also gonna want a hefty amplifier for them. 

Thats kind of where I’m sitting at the moment as far wanting to hear another ribbon/amt type of tweeter. I wasnt sure if the tweeter used in each was the same unit or what have you. Amplifier won’t be an issue: an Anthem P2 would be powering it or one of its little brothers. Plenty of watts and current on tap. As far as bumping up to the Gold 100, I might be inclined to take it a step further and just do the Gold 300. Small floor standers perform quite well in my modest listening space. Appreciate the response 👍 

I hear what you’re saying about getting the 300. I would like to point out that as nice as the ribbon tweeter is, the 8 inch woofer is kind of the star of the show without realizing it.  So in hindsight if the room could handle it, I would look at a 500.

The same MPD III Tweeter is used in all the speakers. The tweeter housing is implemented differently.  

• Studio 89: The tweeter is integrated into a unique, compact MTM (Mid-Tweeter-Mid) point-source array. It features a specialized gold/copper-colored aesthetic trim and an intricate hexagonally-patterned mesh grille derived directly from the Hyphn.
• Gold 100 / 300 / 500 6G: The tweeter is housed in a clean, isolated metal "mid-pod" enclosure alongside the 3-inch midrange driver (on the 3-way models), matching the visual design and specific waveguide needs of the Gold 6G cabinet faces

Yeah I can kind of get what yoir getting at with the larger woofer, but lemme up the ante once more n just say if I was going to invest in the gold 500 I'd probably spring for the Platinum 200 as it really is the perfect size for my needs... but anyhow! lol

Just out of curiosity, were you able to compare or discern much difference in bass response out of the 89s vs the 50s? In the reality of it, if I decided to move on a stand mount / bookshelf they would eventually move into a rear channel role of just "jump into the rotation" type of role. Obviously if I went w floor standers of a higher cost it would be a much more permanent/long term situation. Im more at the stage right now where im curious where Monitor Audio is going to sound in my environment... its just next to impossible to audition in my neck of thr woods being pretty far from any highly populated city. Basically just like trying out different/newer selections as economically as possible! Appreciate your input so far, thanks!
