What makes speaker's sound big?


Does a speaker need to have many drivers or a large driver area to sound big and fill the room?
I am asking this question because I have a pair of tekton design double impact and would like to replace them with smaller speakers and a pair of subwoofer's to better integrate the bass into my room.
I just borrowed a set of B&W 702S. The are good but the just don't make that floor to ceiling sound that I like.
Maybe I have already answered my own question (: But again I have not heard all the speakers out there.
My room measure 15x19' and the ceiling goes from 7.5 to 12.8'

1. The ROOM is more important than the "stuff" you use. This was made clear when various "high-end" manufacturers entertained me in their showrooms and showed me how good and bad the same stuff could sound when the room was changed around or things moved.
2. ALL BOXES DISTORT.
3. Horns belong on the top of poles at high school football stadiums.
4. Pure electrostatics will burn your ears out (listening fatigue) fairly quickly at any volume.
All your post will be very useful to others.....

thanks for that....

Only a small observation about your righfull remark that boxes distort the sound....

It is precisely the reason why especially with boxes speakers damping, isolation from vibrations and controlling internal resonance could give so much correction and compensation... It is precisely for that reason that ACTIVATING the room with the pressuring engines which are my 18 Helmholtz tubes and pipes compensate in some degree for this distortion.... Dont rectify it completely, but compensate for a specific pair of ears: mine....Musical timbre perception here is the key to feed back listenings experiments correction.....


Boxes are not perfect but could be very good for the price in a small room.... I succeeded...Cost of speakers: 50 dollars used....And i prefer my sound to some 250,000 dollars system i listen to on youtube where the room is catastrophic and nobody ever even has been conscious of this fact ....

I dont say that my speakers are better, not at all, they are trash compared to costly one, but in a controlled room they can be on par with anything very costly which is working in a non controlled room .... People cannot imagine what are acoustic laws and why they are so powerful....At best they imagine sound waves bouncing from the passive walls....It is way more complex than that... The audio superstition in the market speak the language of electronic design and his measuring concepts, the upgrading motto...This is half-truth....Worst than a lie ....

Being audiophile is more linked to acoustic consciousness than being obsessed by electronic design....All thread reflect the opposite... It is the main reason why so many people are frustrated and deceived by their system.... It was mine to begin with.... It is no more the case for me without any upgrade....



I concur with all your post....

It is very important that all those who reviewed gear in a room realize how futile it is to describe sound that make sense only for their specific ears...

It is very important that people realize that upgrading BEFORE controlling and activating a room is throwing money to sellers that dont care about  audiophile experience and the installation of a system in his 3 working dimensions but about their products first and it is normal....Anything anormal here....It is the duty of people to educate themselves in the way to install any gear in a room....


My best to you.....

Mahgister, I appreciate all the comments and think you are very correct that most of us don't fully appreciate correct room treatments, etc.

The most stunning demonstration I ever heard was at RMAF when one of the Brit reviewers did a session on equipment isolation and good stands. They also had four (2'x4' ?) Helmholtz resonator panels set for all four walls. The Wilson Audio Duettes? were stunningly set and sounded superb with the system sorted.

When the reviewer and the other guy pulled all four stands out of the room the 30+ people inside were stunned at the total collapse of what we had all just heard. Sure, there was music; but the difference was off the charts (worse).  Then they put the resonator panels back and the music came back. It was aurally incredible! No tricks, no stunts.

Sadly I've not had the patience or knowledge to recreate this in my room although I feel it is very room dependent in terms of the individual design, much like it seems your brick and pipe devices are designed.

Thanks for you kind appreciation...

I thank you for your post that will remind all readers that NO upggrade can replace the powerful controls in the three working embeddings dimensions of any audio system... Especially the acoustical one...

By the way it is possible to replicate what you listen to at no cost.... It takes only time for listenings experiments.... It is way better than to boast about a 100,000 bucks amplifier like some reviews did.... 😊
Accurate frequency response AND coherent phase from 17hz to 30khz and listen at reference volume. 

Result: BIG SOUND. 

One does not need large speakers to achieve big sound and throw an immense, deep soundstage that goes on forever. But the room size matters, distance to the speakers, room treatments as well as the specific drivers for spl potential. That's why to get the above, larger speakers are often needed for large rooms. 

Can you ditch the DDs and get that in your room? If your room is fairly lively, undamped and you can sit close, yep. Obviously, not without subs and expensive speakers. 
Not having read every response I would say that the amplifier has a hell of a lot to do with the sound..
