What size room are the KLH Model Five and JBL L100 Classic speakers good for?

The size of the room in which you are planning to use these loudspeakers is an important decision factor. Here we have compared their suitability to various sizes of environments considering their size and max power parameters:

Listening Environment* KLH Model Five JBL L100 Classic
Near-field Bad Poor
Small Room Poor Average
Mid-size Room Good Good
Large Room Good Average
Very Large Room Poor Poor

(* Approximate Room sizes: Small < 100sq. ft / 9 m2, Mid-size: 100-220 sq. ft / 9-20 m2, Large 220-400 sq. ft / 20-36 m2, Very Large: > 400 sq. ft / 36 m2. Average Floor Height: 9" / 2.7m. Typical room sizes differ from country to country, and the actual listening experience changes depending on floor height, room shape, surface materials, listening position, speaker locations, etc.)

The sections below take each area in turn: drivers, frequency response, physical size and what you get in the box.

Frequency Response

Model Five has a frequency range of 42-20k Hz whereas L100 Classic has a frequency range of 40-40k Hz. With a minimum frequency of 40Hz, the L100 Classic can go slightly deeper then the Model Five's min frequency of 42Hz.

The graph below depicts how these two speakers compare with the max, min and average Low Frequency values of other speakers in the Floor-standing class in our database.

Low Frequency

Min
Average
Median

Neither pair reaches down to 20Hz, the usual definition of full-range, which is normal for speakers of this size. If you want the bottom octave for movies or bass-heavy music, add a subwoofer to whichever you choose. Visit our Powered Subwoofers section to find out more about the available options.

Impedance and Sensitivity

Model Five is a 6 ohms speaker compared to the L100 Classic which has a nominal impedance of 4 ohms. Lower impedance speakers, especially the ones that are rated at 4 ohms may put more pressure on the amplifier unit especially when played at high volume levels, so make sure the amp you pair with the L100 Classic can provide this impedance level.

These two speakers also have different sensitivity levels. Model Five sensitivity is rated at 90.5 dB and the L100 Classic's is rated at 90 dB. This 1 dB difference makes the KLH Model Five a more sensitive speaker compared to JBL L100 Classic, hence will play louder with the same amount of watts.

Power Range

Power range is the range of input power in watts RMS that a loudspeaker is designed to handle. Staying within that range gives nominal performance; driving the speaker beyond its maximum wattage can damage it.

Both handle the same maximum of 200 watts RMS, though Model Five is rated 20-200 watts and L100 Classic 25-200 watts.

Note that higher power handling does not make a speaker louder: that depends mainly on sensitivity and impedance. The calculator below shows how loud each of these actually plays on a real amplifier.

Which plays louder on your amplifier?

Starting with a popular amplifier - change it to the one you own, or any you are considering, and watch both numbers move.

Physical Specs

The size of a speaker can sometimes be an important decision factor due to space constraints or in some cases purely for esthetic reasons. In this section, we are going to compare KLH Model Five's and JBL L100 Classic's external dimensions. KLH Model Five has external dimensions of 870.0 x 350.0 x 330.0mm (34-1/4 x 13-3/4 x 13inch) whereas JBL L100 Classic has external dimensions of 636.5 x 389.6 x 371.5mm (25.0 x 15.3 x 14.6inch).

KLH Model Five is 39.6mm narrower and 41.5mm less deeper than JBL L100 Classic but it is also 233.5mm taller.

Verdict

A floor-standing against a bookshelf. They are built for different places in a room, so start with where these have to go rather than which looks better on paper.

AreaBetterWhy
Bassevenly matchedMuch the same reach (42Hz vs 40Hz).
Amplifier needsevenly matchedSimilar sensitivity (91dB vs 90dB) - both want much the same power.
Amplifier matchAKLH Model Five is the easier load at 6 ohms; the other is 4 ohms and wants an amplifier rated for it.
Headroomevenly matchedSimilar power handling (200W vs 200W).
SizedependsSimilar cabinet size - neither is easier to fit.
TypedependsA Passive Floor-standing against a Passive Bookshelf - a different job rather than a better one.
CabinetdependsSealed vs Ported. Sealed is tighter and happier near a wall; ported digs lower but wants space behind it.
PriceAKLH Model Five is cheaper - $2,500 against $4,400, about 43% less; arguably a different class.

A KLH Model Five  B JBL L100 Classic
depends neither is better in the abstract - it turns on your room, your system or how you will use them. Only specs published for both speakers are judged; anything missing on either side is left out rather than guessed.

Which should you choose?

KLH Model Five has the edge on paper, though the margin is not large. The rows marked "depends" may matter more to you than the score does. Match it to your room: we rate KLH Model Five the better fit for a large room, and JBL L100 Classic for a small room. If your amplifier is modest, vintage or valve-based, KLH Model Five is the safer partner - the other will want more current or more watts to sound its best.

And remember what a spec sheet cannot show: how each looks in your room and whether the finish suits it, what dealer support and warranty are like where you live, and how they actually sound to you. If you can hear them first - ideally with your own music - that will tell you more than any number above.
