F4 listening impressions

[timbarnes]

No room treatments to speak of: a carpet in the middle of the floor, and lots of books. Also somewhat open at the back through a double-sided bookcase.

I did have some bales of R13 fiberglass in the room for a while (under the piano). Not sure they helped.

You seem to have a lot of uneven surfaces with book cases. That helps.

I bring it up because just the other night, I made some small adjustments to my room and it cleared up some haziness and improved image balance. It even tightened up the bass in a basic open baffle design.

I have a barn shaped room with 6 sides and back and front. There's 5 bare, flat, long surfaces. I used 10mm wood cubes attached with blu-tac to breakup the waves a bit. Just using 2 in the corners behind the speakers worked wonders. Sounds nuts, I know, but it helped.

I guess what I'm trying to say is, sometimes it's not our electronics that are to blame.
The room itself plays a big part, yet it's often ignored.

I once received a letter from the late Senator Strom Thurmond, saying "Such a pleasure being interviewed by you". Regards

I'm sure you're right. I keep thinking about ways to control the room. One idea that's been suggested is to spray gunk on the underside of the floor...probably not going to happen. But I do have lumpy bass, and perhaps something in the corners would help.

A simple bass trap could be made from concrete post forms (cardboard tubes). Cut to size, paint and place in the corners. Just to test. They don't need to be stuffed, but can be wrapped in a cloth to improve look. Just a suggestion. Everyone's room is different and take some experimenting.

Have you done any room treatments?

No room treatments. I do have a carpet in the middle of the room and lots of books. Also the back of the room is permeable: the bookcase is double-sided so sound can "leak" out of the back of the room.

To make things worse I also have a baby grand in the room, which I suspect gets excited by the music when it's loud...

But to re-iterate, the combination of BA-3 and F4 continues to be stunning, and I find myself listening to more and more music. The biggest bonus seems to be that my CD player (Naim) is much, much more listenable.

The bass in the room is quite variable depending on where I sit, but that's OK - I have spatial tone controls .
