I agree with crwilli's answers.

Thank you crwilli for the timely response, I appreciate the help and will attempt this process soon.

Thank you for the welcome Masterlu, looking forward to the knowledge gained from this board.

You’re welcome!

Question:

The Sumiko master set-up process has the initial placement focused on the best bass.

My issue is I find that the better bass is closer to the wall placement wise, but the better / deeper soundstage happens when the speakers are much further into the room.

Seems there has to be a compromise between bass and depth-

Am I missing something?

Do you mean better bass or louder/stronger bass? For what it's worth, I find stronger bass closer to the wall, but this is created by reinforcement and reflection from the floor/wall intersection. However, I get clearer, more well-defined bass further out from the wall. I think the Sumiko process is designed to find the spot with the least impact from cancellation nodes, which should provide strong but not over-emphasized bass from wall interactions.

Great response Tony. I do believe they feel the ‘best’ bass is not necessarily the most bass. It’s about smooth with minimal dips and peaks. I forget the exact language in one of the sets of directions I have seen but it’s something like …When the speaker couples with the room…

I am sure Bill (Metaphacts) can better define the goal.

The challenge with full range floorstanders is that best bass performance* and best spatial performance are often mutually exclusive. I’ve used the Sumiko process, the Wilson process, and in-room measurements and sometimes you just have to experiment and compromise one or the other. There is no panacea setup process.

* best meaning flattest possible in-room response.

The goal is not the most bass.

Output - Does it have sufficient output
Extension - Does it go low
Linearity - Can you hear all the notes as they were played?

Picking the anchor involves choosing the best balance of these. John Hunter, one of the authors of Masters, would contend after about 500 set ups this process would begin to become intuitive.

Most set up systems try to answer the same questions. Set up processes do it in separate ways and are often more amenable to some speakers and not others.

For instance, a Wilson does not work using Masters. Why? You do not rake Wilsons - the proper alignment at the listening position is calculated and set in the nomographs. Raking a Wilson screws it up.

Masters works perfectly with a Sonus faber Amati. But you could easily use WASP as well. You would just have to add rake to the end.
