...and why would there be a difference, if any?
Isn't FRFR the ultimate goal of hifi??
Hifi speakers are not as robust and a little more distortion is acceptable in musical instrument speakers.
What is FRFR ?
full range, frequency response. Full Range usually refers to a single driver (no crossover), versus the 2-way, 3-way, or more-way PA and hifi speaker designs.
And also the use/pairing of speaker with (XOver + tweeter, etc) can imply a different frequency response in some cases of FRFR and hifi type speakers (eg; woofer, mid-range, full-range).
In practical terms, FRFR speakers tend be more akin to a PA woofer or 'mid-range' type driver. They often have high power ratings too. Like printer2 said, a hifi speaker ('woofer', full range speaker, etc.) is a more specific application having lower power rating, is often carefully designed into/around a specific cabinet design with a particular crossover and horn/tweeter, etc.
HiFi speakers have a very soft outer ring on the edge for reproducing low end frequencies at low to moderate volumes. They move much more than a guitar speaker, and if you tried to use a HiFi speaker in a guitar amp it would blow in very short order and have very little headroom at even moderate levels.
Full range, flat response
No. Live performance and listening in quiet are two different things.
FRFR speakers are very efficient but also very tough to extract the most volume out of any given power. They're often coloured by the combination chosen and enclosure. You use your eqs to get the sound balance right, and kill any ringing feedback. Often they are used in a non optimal space like a bar with lots of furniture and non-acoustic things like human bodies where you don't want them.
They can be quite spiky in certain Freq bands. They have to withstand abuse but still sit around 100 db/spl to get vox over the band.
Hifi speakers are usually low efficiency but high fidelity and carefully matched to each other and enclosure. Not designed for abuse, often efficiency is only in the 80-90db range. But you can hear the rosin squeak on the second violin on your Mahler. .
I think the OP was more about full range flat response speakers being the same or very similar to hifi speakers which are designed to have a full range and relatively flat response. Home hifi speakers may have foam surrounds and home speakers will be built differently than commercial equipment. That said, there are numerous FRFR speakers being made with coaxial speakers and a cross over. There are even some three way systems with cross overs that are designed for instrument reproduction. Some of the better, and flatter PA speakers are routinely used as FRFR speakers.
To answer the OP, there should be very little difference between a dedicated FRFR instrument speaker vs a well designed HiFi speaker. FRFR speakers are not like a guitar amplifier or speaker cabinet, which are designed to amplify an instrument. Thus they may be full range, but they are not designed to be flat. The FRFR is specifically designed not to "color" the signal that it receives like a guitar cab is. In practice, nothing is perfectly flat in response and there will be some color contributed by the speaker. It just will be a lot less coloration than you would get from an instrument cab.
Think of them as a stage monitor or similar to a keyboard speaker.
Hi fi speakers have a foam surround allowing the cone to move with minimal signal. Guitar speakers are more robust.
Full range flat response I'm not sure about in comparison. It may be more of a 'design for tone' thing than a structural thing. Hi fi speakers would usually have a woofer and mid range and tweeter or etc. So not full range .
FRFR are meant to be flat frequency response from top to bottom. Originally designed for studio use, for accurate sound, NOT good sound.
Hifi speakers are usually tailored to sound good - they exaggerate the highs and lows.
That is pure BS! The aim of every reputable hi-fi speaker designer is flat frequency response. And, only a fool would think that boosted bass and treble sounds good, like a high school kid playing with a graphic equalizer. The main difference between a FRFR speaker and a hi-fi speaker is that guitars put out a lot higher average signal than recorded music does, so a FRFR made to handle a guitar power amp needs to be more rugged like a guitar or PA speaker.
The mighty Klipschorn and La Scala are some of the most highly respected hi-fi speakers of all time, and their sensitivity is 104db at 1 watt! They can produce concert hall volume from a transistor radio!
You're talking through your arse.
Hifi no more exists.
Today there is hi end.
Hi end goal is to reproduce a flat reponse full range, the same as FRFR, but with cost no object.
hi end tends to be FRFR with a touch/nouance/timbre given by the constructor, with a very high resolution on the reproduced musical message, that is crucial; you can ear even the smallest detail clearly.
And hi end is meant to be used at home, in a very carefully selected electronic chain that specifically match with that speaker.
Of course it could be a 1W system as a 1KW system, it can be tube based or transistor based or hybrid or class d, it can be 3 way, 2 way, monoway, biamp, active crossover, passive crossover, digital crossover, r2r dac, delta sigma dac, dsd, computer based, et cetera.
So hifi or hi end mean all and nothing, so wide is the range of the users.
Frfr is a bit marketing: it is a PA (rugged, hi power, very reliable) in a guitar cab form factor.
It is 2 way or 3 way, active crossover, class ab, class b or class d, no tubes, high power
The best Frfrs have a wide dispersion, that emulate the wide dispersion of a real guitar speaker (but even a good PA or hifi/hi end system presents wide dispersion).
Frfrs are meant to be used in a digital chain, eg a single multifx pedalboard connected directly in a frfr cabinet, or even in a more complicated scenario, eg your tube amp, a torpedo loadbox and ir loader, your audio interface, your vst plugin and in the end the frfr, that in this case acts as your studio monitors, but it is not in stereo on your desk but it is (generally speaking) in mono on the floor, with its large dispersion that emulate a guitar speaker.
I think the best pro of an frfr is the same as a studio monitor or a PA speaker: you can emulate your preferred gigs even at low volume.
I love my FRFR!
