Bass problem is 60hz approx - but you dont actually know that for sure obviously, cant tell that by ear - saying we do know that is the problem. You seal the speaker and that reduces the bass at 60hz by 10db and reduces the boom somewhhat - thats great
But and its a very big But - what about 50hz and 40hz and 30hz and 70hz and 80hz etc that are all reduced as well as a result of sealing the speaker - we have affected all the other bass trying to reduce just one small range of it??
That is what sealed enclosures do - they cut off earlier in the lower frequencies. A ported enclosure extends the bass - but has a steeper roll off at the lower frequencies. At some stage in the lower frequencies the bass response is going to be similar for both sealed and ported.

In most rooms that I have seen measured the bass problems are horrendous and the bass is horrendously bad. And most of the time overall there is not nearly enough bass - so to try and reduce the bass furher by sealing the speaker to fix just one issue by Pure Guess work - is pointless, bad practice and will result in worse sound not better. Its not a sensible thing to do its an ill informed thing to do and mistake - unless you have measured and checked and confirmed it will fix the problem - I know for a fact bass in a room doesnt work like that - its far from that easy
The original poster has too much bass - so blocking the port and reducing the bass will be a solution. This solution of blocking the port has NEVER been stated to achieve the same results as a DSP solution. It is immediate, cheap and reversible.
If the listener enjoys the reduction - then great - nothing lost. If not, then they can pursue the DSP solution. DSP is not the only solution possible, it is only perhaps the optimal solution.
If sealed enclosures were such a poor solution - no hifi manufacturer would supply them.
