It sounds like you're overreacting. I have been using a TACT system for close to 2 years and it's a wonderful piece, but it can easily be misused or misinterpreted. The key to using the TACT is obtaining an accurate measurement set. For best results you need to set the measure clicks to at least 50 and take readings from several different positions approximating where your head is during normal listening and use the averaging function. It's very important that the room is absolutely quiet during the measurements. HVAC noise, passing vehicles, cycling refrigerators can all screw up the measurements. Assuming all this was done correctly you still have to understand what the measurements are telling you. NO ROOM EVER MEASURES FLAT IN THE BASS. If all you have is a single spike at 40Hz and otherwise the system measures smoothly, then you've already done a great job. A relatively narrow bass peak can be easily dealt with via EQ or tuned bass traps. Depending on your taste in music, a little bump at 40Hz can be quite helpful in that it adds some growl to bass lines. Flat bass response can sound slightly anemic.
Ask yourself a question - does the system sound muted? Use the measures only as a guide and then let your ears tell you what is right.
