3 way Bluetooth speaker (component check)

So im designing a 3 way bluetooth speaker but im not completly sure what components to use..

Here is a list of what i currently have in mind:

Subwoofers 40 - 1k Hz: 2x (Tang Band: W3-1876S)
Midrange: 1k - 4k Hz: 1x (Dayton Audio: ND65-8)
Tweeter: 4k - 20k Hz: 1x (ND20FB-4)

Amplifier: KABD 430

My question is are speakers good, do they compliment each other, is it a suitable amp or are there better alternatives to this. Keep in mind im trying to make somethin as small as possible.
