Knott,
Thank you for taking the time to look through the other thread to see my Tannoy speakers.
Yes, you are correct. The back of the Tannoys are only 18" from the wall behind them. In this placement, having the bass reflex ports on their front is probably a blessing as compared to having a rear port design.
I would imagine having the backs of the Tonians only 18" from the rear wall would not be ideal. By having them that close, would the affects be that the bass becomes boomy and/or the depth of soundfield be shortened? How much room do you think they would require?
I have never owned speakers with a ribbon tweeter before. I would imagine that it may contribute the biggest difference in the presentation of sound, vs the dual concentric style tweeter that is in the Monitor Golds. I of course have not heard the Tonians, but from what I am reading, the midrange on down seem like they may be more alike sounding than different.
I appreciate your comments.
