How far can room treatments solve boomy bass?

Monitors are perhaps a safer move. Assuming that people seems to go through acoustics half hearted. The risk with fullrange speakers (most often floor standers) is always that bass modes will be unavoidable and it cost some to get the bass modes an the rest under control.
Looking through some threads, also talking to acoustics that work this every day, has made me understand. None of the audio-bugged i have visited has done what is needed to make the environment nearly as good as the rest of the system.
Another bizarre thing here is cable dealers, who claims this can be solved with different cables. I guess a graph can tell each and everyone how much bass modes and dips can affect the whole frequency range. Basically, the room (environment) is as important as the system.

Any cable that corrects room response issues is seriously broken. Why do people fall for this crap?

The cable makers have to make such claims in order to justify the high prices asked for their products. But this is off topic.
Man I tell you boomy bass used to be thought of as a problem solved with few interventions and no fancy sophisticated acoustical analysis computer programs were employed. Has the OP tried any of the suggestions and if so what are the results?

Good question, i have tried them all. What i ment was, hope he does not fall for a sales-hype that can come in many different suggestions. I also ment, that an idiot must realize reading a graph, that not many things can solve bass modes of significant + db's. I can measure a somewhat result of a bass panel absorber. What they do for a low bass peak mode is pretty much nothing. That is raw fact. A XTZ RA pro II cost no more than a rather cheap power chord. Such kit's did cost alot a few years ago. Don't rely on things you can't verify. There are to many vested crooks wishing to earn your cash. When i mention this cable soloution, it is actually a suggestion i was getting from a manufacturer. He was so into this i began to wonder if i could walk on water buying a set of his magic cables. Ah, you get the point. I suggest the OP try to mail Richard Bird at Rives and also Gik acoustics, just to see what responses he'll get. Both companies are very nice. From this point he can figure himself what to do. As mention and to repeat myself, the RA pro II is not to throw money for the pigs. It is a good way to actually see, understand and learn what to do.

Mechans, ofcourse. Back off a few years or more, such programs (complete kits) was very much more expensive and not as good. Not to to mention, as easy to use. The XTZ is advanced and great quality for a more than a resonable cost all new. This is also why many companies could rely on the fact, we could not check facts for ourselves, but rather relied on their sales-hype.
