What would your "perfect speaker" sound like.

I Own M-Studio Mv40 speakers self powered...They compared in specs to the 80 hertz limit Of the LS3 5AS...

Instead of investing 10,000 bucks as advised by Mijostyn whose pocket seems without limit...😁

😊

I put a bunch of straws in the Port hole behind , increasing then the volume of the resonators chamber increasing my bass extension and depth then i helped the Tweeter directional focalization to my ears by putting a plastic ring around the tweeters ...

No cost....

Complete transformation of a good cheap speakers in superlative small one......( i arrange an acoustic corner too for them )

I go more down in the bass , and the bass i have have way more extension...

My cheap speakers beat all headphones i ever own...Save my beloved K340...

If you want to purchase a bigger soundfield for more person in a bigger room invest 10,000 bucks in some  good bigger speaker able to go near 30 hertz...

With this money which is more than 10,000 bucks for 2 dac, 2 subs, a DSP you will spare all that useless cables and intermediate stage with one bigger pair of speakers...

It is my advice...

If i listen Organ music with 30 hertz notes myself i quit my little speakers and go on my headphone...

For jazz they are perfect... Cost : 100 bucks...

LS3 5As have no bass below 80 Hz at 3 feet or any feet for that matter. Get a pair of KEF K92 subwoofers and a MiniDSP SHD Studio with two Benchmark DACs. This will make you a 90% system (better than 90% of the systems out there).

Doesn't any one want more bass.....apparently not in their dream speaker. 

Assuming that big orchestra is one instrument, perfect speakers should sound very close to that instrument at any sound level. And if to accomplish that they have to be of enormous size, so be it.

I honestly don’t know, other than it would be so enjoyable to listen to that there’d be no way to make a speaker more enjoyable to listen to. That might involve some elements of extreme realism, and some elements of artful coloration.

Like live unamplified music. 
 

and it takes your whole audio system to achieve something close to live unamplified music, not just speakers.
