Need Help on Dedicated Listening Room


I searched the forum, but no specific info to my problem.
So here is my scenerio.
Room Size: 13' x 11.5' with 10' ceiling.
Speakers: Infinity Composition Model P-FR.
(expect to upgrade to Martin Logan Ascent, Aeon, or Scenario)
Type of Music: Female Vocal like Jacintha, Patricia Kraas, Diana Krall, and I don't listen to loud music.
I have a budget about $2K to tune the room.
My questions:
1) Is the room too small for the present and future speakers?
2) Can I do it with $2K budget?
3) Do you have any suggestion?
Thank You:
Alan

Is your room a "closed-in" 11.5 X 13 X 10?
If it is, you will most certainly be challenged by unavoidable bass modal problems as your first obstacle to deal with. Set up will be critical for best speaker to speaker location, including seating possition(s). There will be trade-offs, also depending on your set-up(long wall vs. Short wall) set up, etc.)
MIGHT I STRONGLY SUGGEST a speaker sellection scenario(in addition to careful speaker and seating possitioning) where you can BIAMP, AND EQ your bass woofer separate from your midrange/hi-freq drivers!!!! IN a room that small, you'll have to overcome some bass anomolies which will keep you in that "small-room-boom" and or "peaky", bumpy, small room sonic signature(which you're trying to overcome ideally).
As it is right now, your Prelude P-FR's(which I used to own by the way) are definitely giving you that "one-note" boomy bass with little pitch definition, speed, and that unavoidable small room sonic signature unfortunately.
I say this and I'm not even in your room!...but I know what's going on there mostly.
In that small room however, if you can get a good Parametric EQ on your bass woofers, and leave your upper frequencies untouched. you can potentially get a tremendously balanced frequency response, while maintaining your sonic purity and integrity in the midrange on up!!!
For a lot of full range speaker situations in small rooms, this is often a tremendously good solution.
Keep in mind, speaker and seating locations as a foundation are still of utmost importance from a starting point. (as you can't overcome bass "nulls", for one.)
After you get your speaker set up for proper response, you can then concentrate on treating reverb, reflections, and other acoustic challenges in the room. Just be careful not to over-dampen your small room. As it's easy to get a DEAD SOUNDIng room easily in small room situations I find.
Yes, indeed, there are lots of books and articles to suggest sound treatments for rooms. But in the end, you'll have to experiment, and try for yourself to know what's doing what! (it will take time and experimentation on your own..otherwise it takes money and professional help!)
Another route you could consider would be smaller satalites and subwoofer combinations. There's more latitude with sub placement vs. satalite placement, since the two usually don't ideally work as good in the same exact location overall! This lets you place the woofer(s) in their best possitions, and the upper frequency units to be possitioned in theirs. Also, you can EASILY EQ a powered subwoofer for ultimate performance!

Books to go through: F. Alton Everest's "Master Handbook of Acoustics(2-3rd addition, as 4th addition has many mathematical errors!!!!); F.A. Everest's "Studio Construction on Budget"; Robert Harley's, "Complete Guide to HIgh End Audio";Back issues of Stereophile Guide To Home Theater's "Home Theater Architect" article(1999-now!)
Or search the net for more acoustics related.

Good luck!
Inherently, especially with lesser experience in dealing with small room acoustic challenges(like you said,BOOMY!), it's often easier to get better overall response and balance from your speakers in a larger room..I agree. There are usually more possible choices in which to place speakers and seats which will yield acceptably good sound for most. The larger acoustic space(depending on how large) will have better spacing of bass modes, making a good placement for full range speakers easier to achieve usually, eVEN with luck!
still, if you do need to use the smaller room, it's workable. It's just a bit more challenging, and requires tigheter tollerances and speaker placment/seating options.
Again, you could EQ out a bass woofer(s) in that small room, after careful speaker set up, and get some dynamite results! Rives sells the PARC, and there's other good Parametric's out there for not to much that will also work.
Infact, most audiophiles can get some spectacular results in small rooms if they employ some good placement strategy and experimentation, and integrate a good EQ into their BASS woofer!(biamp,sub/sat,etc)
Good luck
