After you try stuffing the port (experiment with full and partial stuffing) Experiment with toe in.
I have some old Boston Acoustics T-830 3-way mini towers that sound great very close to the wall. They are sealed (Acoustic suspension).
I upgraded to Canton Ergo 3-way towers that are ported in the front. They sound awesome to my 65 year old ears. Canton says their speakers can be placed 12" from the surface behind them, even though the Vento 826 bookshelfs are rear ported.
I believe NHT is back in business and they make highly regarded acoustic/sealed speakers. You could also focus on front ported speakers that are less influenced by the surface behind them. Some examples are Monitor Audio and SalkSound.
