Nice little speakers, with emphasis on the word little.
Also, obviously not matched to the rest of the system, particularly the room.
What do you expect from a 5 inch woofer?
Real bass? GMAB!
I need to look for a warm, musical speaker as the main to better suit my need, and set these Tsis as surround speakers.
Perhaps, but have you ever heard of subwoofers?
What about experimenting with location in the room?
Then, there are always acoustic treatments. Chances that a room is ideal for an arbitrarily-chosen speaker = approximately zero.
I mainly listen to music, any kinds of music, like classic, pop, rock, etc except heavy metals.
Doesn't matter. A good system will be acceptable with a wide variety of genres and recordings. I'.m not saying that any speaker is ideal with everything, but the better the room/speaker balance, the larger percentage of recordings will sound acceptable.
One of the things that gives me a headache is people who literally run an ever-changing parade of minispeakers with 4-6" woofers through their listening rooms on a railroad track. To a certain degree they are going to tend to sound the same.
Plan B: Spend a few hundred dollars on a good 12" subwoofer and position and balance that out. It is truly amazing what extending clean bass from about 100 Hz down to 30 Hz does for the perception of midrange and treble.
I've been reading the posts here, looks like Energy RC10 was a pretty good option, but it's discontinued; I have nowhere to buy.
Is there any recommendation that is similar to RC10 or better?
My budget is about what RC10 was.
First recommended option - get a good subwoofer.
Second recommended option (your first choice if money is a problem) is look at speaker placement and room acoustics treatments.
The world is full of really pretty good speakers in crappy locations in crappy rooms. Fixing a room by swapping speakers is like trying to tune a car engine by replacing the shock absorbers.
