Big speakers, are they really the best way to get great sound?

I never said it was a "trick" Do you not know what a straw man is?

My room and system are set up to minimize reflections at the listener. Speakers are ~7.5 feet apart on the 26 foot wall and about 10.5 feet from the listener. The ceiling above the speakers is ~14 feet high.

The rear wave is removed from the Heils and the 2251J crosses over at ~3kHz to minimize early reflections.

Tell you what, you bring your "technology" over here and we’ll listen together. I’m in Orange County, CA and I see you advertise on C/L in LA.

Very true .... Bass control in the room cannot be efficient without controlling the zone pressure distribution ...Helmholtz tuned resonators did it for me in my last room ...

But speakers in a small wood two way box are also Helmholtz resonators ...😊

You can modify the port hole and redesign it as i did ... You can redesign the tweeter radiation pattern as i did ...And the low cost speakers now punch way above his price ...( 100 bucks 12 years ago and i disliked them for 11 years😁 )

Speakers/room relation is one thing that most people dont understand ...

They bought costly speakers thinking that speakers give their optimal S.Q. in any uncontrolled room ... This is false ...

And small speakers without being as good as big one because of bass depth can be more than just good in near listening in a dedicated acoustically controlled corner ...

The impact and change of a small speakers with a 4 inches woofer as mine could be astonishing ... ( i go 50 hertz clear no boominess)

I believe only in acoustics .... Price tag means nothing without acoustics ... And with acoustics a well designed low cost speakers can punch above what is expected ...

 Then to answer the OP question , the best way to have good sound is learning basic acoustics knowledge not buying small or big speakers ...

Breaking this down to size is oversimplification to the point of misinformation. What matters most are the radiation patterns of the drivers, the maximum SPLs one wants, the acoustical properties of the room (size and proportions are just two of many aspects) and the goals of the system. Boomy bass is almost always more a function of room acoustics, specifically bass absorption than speaker size. Radiation patterns only come into play with dipoles in the bass (mostly). Room size does play a part in the bass but bigger isn’t always better. Bigger just means the problems are lower on frequency which is often harder to solve. But bass absorption in a room matters much much more than room size. Boomy bass is not a result of a speaker simply being too big.

if it is a medium to big room, size really matters...

nearfield a different story

Even in nearfield the acoustic of the room matter ...

If we compute the number of times the waves at the speed of sound cross the walls of any room to our ears, we will be surprized ... 😊

People who think that because they listen nearfield room acoustics dont matter are in delusion not in acoustics ...

And the size of speakers as such even in a big room matter less than the way we understand acoustics relation between speakers/room and ears ... ...

Near field matters but it isn’t an all or nothing proposition. It has pretty much no effect on bass
