Looking for a great front ported bookshelp speaker recommendation

Would add Aerial 5t to list

Ha, I used to be an Aerial 10t owner

+1 for ATCs , @soux advice, and avoiding ported speakers in this case. I have ATC SCM7’s that sit on a dresser (decoupled by rubber/wood laminates) that sound great.

Have a close look at the new EPOS ES-7N - great small speaker designed by Karl Heinz Fink of Fink Team. Front ported and offers the ability to work in a bookshelf or close to the wall or free standing. $2195 pair.

Space inside the cabinet will be a big determining factor for what speakers will fit in your allotted space.

I will add Ascend Acoustics Luna

or Ascend Acoustics Duo V2

Both have a RAAL ribbon tweeter and are front ported. The ribbon tweeter limits vertical dispersion somewhat, so standing versus sitting will vary. The Duo will likely fill the space better, but are taller, or wider depending on how you orient them.

Best of luck.
