Here in lies the problems with big full range speakers like the gold's in that room...First, placing the speakers where they yield the best response in the upper bass, will not be the case for the deepest base. Thus, often, you'll either be dealing with boomy unatural lower bass, or compromise the accuracy further up. Soundstage width must be balanced, and the seats (as the speakers), are going to need be out in the room, probably further than you'd like often. With seats placed properly out at about 1/3 of the rooms's length, you'll have to put the speakers out away from the sidewalls, and closer together, or you'll be boomy bellow 63hz reigion. So, soundstage width will be restricted full range.
If you do place the speakers on the long wall, you can help things often. but you should still consider 1/3 seating locations. Speakers would start at 1/6th from the front wall. If you have a solo-seat setup, speakers should be considered at 1/4 from sidewalls, if you sit in the middle of the room, yet staying 1/3 from front to back. These are good guidlines. But you still need to find where the speakers get best response overall. If you run the speakers as small, it helps your flexibilty, if you go "subwoofer".
Basically, if you run them full range for music, and don't cross over, the above mentioned will be your challenges, among others.
A possibly better option, if you chose to run the strong, dynamic, and deep sounding "Gold's" full range, is to "biamp" them! You can then get a good Parametric EQ on the bass woofers, without affecting the mid/high's! Otherwise, consider a good investment in the Rives Audio "PARC"...the best analog Parametric EQ ever made IMO.
Basiclally, your main challenge in a small room, is yes, the Bass response and setup. You'll have only a couple of options, as is. With EQ'ing you have more.
I could make the Gold's work in that small room, but it wouldn't be easy....
