That mid-bass punch has little to do with deep bass, but probably lies somewhere between 50 to 150hz. That's the typical kick-drum range. There are various problems that can lead to less-than-satisfying bass punch.
One possible problem is an excess of deep bass room gain. This causes the deeper bass to overwhelm the punch bass. That may shake the couch, but doesn't give much punch.
Another possible problem is a poor frequency response in the crossover area. For most folks this takes place around 80hz which just happens to sit in the middle of the punch range. Check phase and distance settings as possible causes.
Weak bass performance of the main speakers is another possible problem. Since the main speakers are usually called upon to deliver the upper part of the bass punch, if they are not up to the task, performance here will suffer. Small bookshelf speakers, for example, are most likley not up to delivering their portion of the bass punch spectrum with sufficient power to be realistic.
As others here have suggested, try to measure the frequency response to visualize where the problem lies. As any physician will tell you, you should diagnose the problem before you treat the problem.
In some cases, something like an MBM-12 or perhaps some other small supplimentary sub to enhance the range between 50 and 150hz might be a solution, but again try to understand where the problem comes from before trying to fix it.
