IF (???) budget and/or available space are constraints,
@S. Ghosh -- you might want to consider a single-driver (so-called "fullrange") loudspeaker.
Not sure what would be readily available where you live, but there are myriad options, including purchaing a pair of drivers and building (or having someone build) enclosures for them.
Now -- here's the thing. A "fullrange" driver is a big bucketful of compromises by definition, considering that the nominally "audible" spectrum covers three orders of magnitude of frequencies (20 Hz to 20,000 Hz; i.e., wavelengths of ca. 17 meters to 1.7 cm), but most of them employ no electrical crossover to waste amplifier power,
and they can be quite sensitive. A variety of tricks are sometimes used to enhance the perceived performance of these drivers -- e.g., horn, pipe, or transmission line loading for bass enhancement, or parasitic ("whizzer") cones or dual-compliance suspensions (
a la the Altec "Biflex") to extend treble response. It is possible to make a "fullrange" driver that is fairly sensitive (even
very sensitive, at least by modern standards). The optimum size for a single-driver
seems to me (empirically!) to be about 200 mm (8 inches, where I live) but there are many such drivers commercially available that are larger and smaller than that.
These are currently fashionable in some circles:

Fostex (Foster) has a long-standing position in manufacturing "fullrange" speakers and offers designs and kits to build enclosures for them.

The classic
sine qua non were/are the drivers from an eccentric British company called Lowther. These drivers are
interesting and very polarizing in the 'community'. They're
very sensitive, though -- and
very expensive.

There are other modern manufacturers/distributors of "fullrange" drivers. In the US, Madisound and Parts Express are good sources. Parts Express has some unique offerings sold under their "Dayton Audio" brand, as well as some interesting (and not inexpensive) TangBand drivers.
PE's fullrange driver offerings are mixed into the offerings in this filtered view from PE's website:

There are other current production options for both drivers and fully-finished loudspeakers (drivers and cabinets) -- some include various kinds of "passive" networks to improve their performance (at the expense of some sensitivity and dynamics, for better or worse). Here is one (US) example -- also, again, quite polarizing to "audiophiles"

There are also many "vintage" options from companies storied (Altec, JBL, Electrovoice, Jensen, e.g.) and less fondly remembered (Utah, University, Oaktron, e.g.) Even the fabled
retailer "Radio Shack" sold some interesting "fullrange" drivers over they years.
Are these drivers/speakers ideal? Far from it. Can they deliver good dynamics? Yes (in some cases). Are they "colored" (i.e., do they exhibit substantial deviations from flat frequency response)? Yes, almost without exception (and without regard to price!). Do they suffer from other woes not typically found in "normal" loudspeakers? Yes (e.g., Doppler distortion and rising impedance at higher frequencies being among the most typical). Can they sound "good"? Yes (subjectively). They're
absolutely, irrevocably not for everybody. In other words, you'll want to
try before you buy.
HTH (
"hope this helps"), as they say.
