Sorry if this question is elemental  but dont quite get it.  I fully understand why an open baffle speaker needs to be a min of 3 ft from the walls...giving at least 6m delay on the reflected sound so our brains interpret those signals as reflections.  So i have actually have 2 questions...

1-Since the speed of sound is effectively the same regardless of frequency why would the studio monitor not need as much space between it and the back wall?  Is it because it is reflecting upward?  or are we less sensitive at higher frequencies to the reflective timing?

2-Years ago i had a set of Alon open baffle speakers that have both the mids and tweeters open baffle, some of the GR research models are the same....the X-Statics only have the Mids open baffle and the NX Studios have only the highs open....how will these different strategies of open baffle construction effect our perceptions?  IE how do we perceive open baffle sound (reflective) say comparing the X-Statics to the NX Studios?

Thanks.

Good question.

With the NX Studio Monitor most of the energy being directed to the rear is being absorbed and directed upward. So a lot of that spaciousness is placed within the room and not at you in any one direction.

You have to look at it as those two speakers were designed for different applications. Each has its strengths but neither has a weakness, unless you are looking for low bass.

I’ll throw out a couple more questions:

Why did you decide to not front-port the Studio monitor? Yes, there’s a compromise, but it seems like in this design, the extended low-end may be worth the trade-off.

Is the sloped top necessary for the design, or could the tweeter exist free-standing (only attached to the front baffle)?

The woofers weren't designed for a ported application and a ported box would nearly double the size.

The open top is what makes closer wall placement an option. If the whole tweeter baffle had nothing around it at all then it would have to be placed three feet or more out into the room, and that would blow the application that it was designed for.

You rock, Danny! Thank for the insights.
