Speakers are tools and there are as many different ones as people.
First you need to figure out what you want from the tool/speakers, then you can pick a style to fit your needs.
You mention clarity....clarity in detail/dialog ?
What have you done on your current system to improve clarity......how is your system configured, does it have room correction, does it have EQ built in.
If you feel your current sub is overkill, stay with it....
You certainly do not have cheap or junk speakers, so they should be able to perform clearly once configured correctly.
There is nothing wrong with playing with the settings if available to figure it all out and see what you like.........pick a quality song you like and start playing around with the EQ......
Move each slider on the front left and right when listening in stereo and see what each frequency is/does and then once you have played around for a few days and understand what you/your room and your speakers need to deliver the sound signature you like, then get down to business on the rest of the speakers.
You can set the EQ flat and raise whatever slider the same on each speaker 2 or 3 db or down and listen to the song again and again and again taking in what each slider frequency does and what sounds good to you. If your receiver does not have room correction or EQ, I would consider that before replacing any speakers as the next ones might not do any better in your room to your ears.
We all hear differently and we are all different levels of hearing degraded......it goes with age and how much noise you have been subject to, so one knows what you are hearing but you.
Here is a intro video to understand room acoustics better if that's something you are interested in......while not mandatory in every room , it certainly does not hurt to understand it some and see if one of the main issues might be effecting what you are hearing in your room.
Depends on how deep you want to understand sound..........you can play with the EQ until your happy and enjoy or you can take in room measurements with a mic and see exactly what is happening in the room. But even then it will require EQ to correct anything with frequency response.
If you do not want to go crazy with acoustic sound treatments and measurement mic readings, the best thing is to get familiar with the EQ and what it does...........learn it/ play with it and at that point you will be able to identify a speakers strong points and weak points. Then you will have very good idea of what speakers to look at and if they meet your needs or if you even want or need different speakers.
In the most basic ruff explanation, speakers all have what I like to call a native sound, this is when they are first hooked up with no EQ, no room correction, no bass or treble added. Play a song, they will have a native uncorrected sound, set the next pair of different speakers in same spot and play the same song and the native sound will be some what different. This is what I call the native sound. Most decent speakers can produce from 80hz-20khz .........they will all have a different native sound.
You can keep trying speakers until that native sound fits in your application,what many do, or you can use EQ to bend the sound to fit you and your ears and your room. Taking variances on speaker style and advanced audio listening away....nuances and small variations. Most quality speakers can be made to produce a flat frequency response, once you have this and room issues corrected , you can then start to dissect the sound signature of different speakers better.
There is no right or wrong way to end up at the destination of a sound you are pleased with.....just depends on how you want to get there.
Don`t get me wrong, different speakers in a perfect environment will sound very different and more expensive speakers in most cases have better quality parts etc etc etc. But which ones fit you is only something you can know and the way to know that is to experiment and figure out what you like and need a speaker to do. Once have identified these things, then you can choose the right speaker/tool for the job.
You just need to define what clarity means to you and what settings will get you there...or as close as possible with the equipment you have. Once you get close, you will then know what your equipment can or cant do and make a selection based on that need.
Take a known quality recording and start adjusting and listening.........then repeat, change that setting back and adjust another slider up or down on the EQ and listen again and again......keep adjusting and resetting and changing it until you end up in a methodical way to a end point. Write things down as you go if needed.
I like a methodical A-Z method......start with the EQ sliders on the left....raise the first one on both speakers 3db and listen....set them back to the middle and listen, then set them 3db low and listen again. Once you work your way from left to right in this way with each slider, returning them to 0 and moving to the next one......in a few hours you will have a good idea what each one means to you. That is enough information/learning to start adjusting more than one to what you think it needs and listening again and again until you end up some where you like.
At the end of that, which could take a week or 2 getting used to and listening to different settings, you will have a better understanding of what is or is not missing in your speakers.......this will increase your chances of getting a different speaker,..if needed..., that best fits what you need the first time.
What a measurement mic does is eliminate all that trial and error. You get set up, take a measurement, see exactly what is happening and adjust the system for as flat as a response as possible. Which gives you a place to start listening from and also allows you to measure as you adjust for personal tastes and see exactly what those tastes are. It sounds simple, but can take just as much time and adjusting as any other method....it just allows you to see what you are adjusting and gives you base line to start from. It is by no means a short cut......
