Floorstander or bookshelf?

>I did not make any treatments.The speakers are placed 5ft.(1.5m) away from the side walls and 1.3ft.(0.4m) in front of back walls with 6.5 ft.(2m) distance between them. I find the bass to boomy for my tastes.

As expected. You're going to pickup substantial gain below 110Hz plus whatever you get due to the listener's rear-wall proximity which is also shorter than optimal.

A short-wall placement with the same speaker separation would make things better.

If you can't do that, a shelving high-pass filter would be a fine idea.

Some speakers (Revel makes a few) have a boundary switch which does this.

>What do you consider that should be more appropriate for my room , a bookshelf or a floorstander?

In-wall. Your speakers aren't far enough off the front wall (about 5') for their front-wall reflections to be perceived entirely as reverberant field, aren't far enough out to develop sound stage depth that you'd loose by going with in-walls, and moving to in-wall speakers will eliminate baffle diffraction effects.

Note that by 'in-wall' I mean speakers with well-braced high quality enclosures that mount in the walls (Triad?), not decorator approved units which rely on the resonant dry-wall cavity.

BTW, I also agree to make sure what you have is tuned in optimally before changing.

I am using MA RS6 with Nait XS in similar size room. My speaker placement is closer to the sidewalls and front wall than yours. At first I found the bass to be a little excessive, but I put the foam plugs in the rear ports. This cut the boominess. Now bass is more natural and well balanced. One thing that probably helps in my particular room is that I have 11 foot cathedral ceiling.
I have also found that the MA speakers are a nice match for Naim gear, after playing around with speaker placement.
The other speaker line I would recommend is Harbeth.
Are you using the foam plugs?

Kerio..i agree that you need to address the speaker/room interface before entertaining new speakers. Before treating the room, you can get potentially great enhancement in your in-room bass response by merely playing around with speaker placement. I am attaching a link to an exerpt from Robert Harley's (editor of TAS) book "A Complete Guide to High End Audio," which has a detailed section on speaker placement, starting on page 7 of the 21 page booklet exerpt. There may be other helpful hints in there as well on common room treatment suggestions as well. But first I would try tweaking your speaker placement. One suggestion is to pull your speakers out further away from the backwall, as that should definitely reduce boomy bass. Here's a link to the exerpt, which can also be found at the TAS website: http://media.avguide.com/excerpt.pdf

Hope this helps

Either can work but good choices for floorstanders in a room that size will be more limited. For floorstanders I'd look at OHm Micro Walsh talls, 100.3s (there are a few pair up for sale on agon currently for well under $1000), 1000s, Totem Arro, or various smaller Klipsch HEritage series floorstanders to start depending on your sonic preferences.

treat the room first....biggest bang for the buck and most necessary

I second the room treatment suggestion.

The comment about bookshelf and room size suggests that the room is on the small side. The smaller the space the more important the treatments become.

The room is about 50% of the sound. Money spent there will probably have a greater return than that spent on H/W - at least up to the point where the room is under control.

I would rather have an average system in an excellent room than the other way around.

Good luck,
Jim

Thanks for answer,

I find the bass to boomy for my tastes.
The excessive lows tend to "color" the voices and to make the sound somehow artificial.
I suspect that a bookshelf would be more adequate taking in account room size.
As for RS6, everybody seems to agree that are very good speakers for the money but wouldn`t be Sonus Faber Toy a step forward?

Have you treated your room for reflections? Do that first before you do anything else. The RS6's are very good speakers for the cost. Sounds like you just want a better bass response. Overall, this will make a bigger impact than anything else for you right now.
