Curved speakers

[east electronics]

I have a pair of visatons that are made to my own taste and made in the past for the previous house i owned .... The speaker had a decent spread and Ι was very happy with it but eventually i am in a new listening room much smaller than the previous one

My box is made front bass reflex features Bass reflex /woofer 8"/woofer8" /tweeter/mid 3" /mid 3" starting from bellow ....The enclosure is designed to be placed in the room slightly leaning looking at the roof ( flat front baffle )

In the new listening room is seems that this speaker is out of focus suppose that you listen to a song that starts with a tempo full set of drums bass keybord and then vocals its all a confused thing ..there is no sharpnes between things , bass also seems to overtake everything ....

ok for the bass i understand that this is made from the room and position of speakers there is a few things i can do for the room but that will come in the feature ....

In between though i had a pair of 2way speakers also made for my own taste closed enclosure 8" woofer and one tweeter ...so i tested those obviously the volume of sound was much lower bass was far less imppressive but there was a huge ammount of sharpness between everything ....everything you listened to was very descret much more cleaner than the big ones

so here is the question

lets suppose that i make a curved front baffle ( internal curve ) enclosure Imagine something like Utopia style but the internal curve will be symmetric to the center of the speaker , and then change also the arrangement so starting from bellow it will be bass reflex / woofer8" / mid3"/ tweeter /mid 3"/ and woofer 8" starting from bellow

is this expected to change something

is this a good idea to work in such an enclosure ?

thank you

Don't know much about the concept, not so many out there but looks cool.

Yeap that is the style

I'd put the woofer well away from the boundaries = centered between floor and ceiling. That would solve (part of) the problem of 'too much bass'
I would avoid the use of a 2nd mid, but that would involve in thrashing the mids and study for another one. Nevertheless, a curved (focusing and pointing at an imaginary center 1m ahead) baffle is good thing

the curved loudspeaker à la Focal is made if I remember to make all the drivers to have the same flight distance when they sum up at the listening spot (listener head) noticed on the manual. They often choose the angles for that sumation focus at 3 meters for suiting most living rooms where the distance between the chair or the sofa and the front bafle speaker is 3 m.

The drivers just don't sum up, as the waves generated by them don't sum but superimpose

 

[diyiggy]

Yes. Better english...
Can we say two drivers in phase sum their spl as the illustration in Dickason book?

No clue about the book, but sum at wherever the focal distance/angle is identical, i.e. literally a 'head in vice' scenario, though really depends on the individual's hearing acuity as to whether or not it's acceptable over a range of head positions.
