What size room are the Definitive DT6.5LCR and Focal 100 IW LCR5 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* Definitive DT6.5LCR Focal 100 IW LCR5
Near-field Average Poor
Small Room Good Average
Mid-size Room Average Good
Large Room Poor Average
Very Large Room Bad 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.

Midrange - -
Woofer 1 x 6.5-inch 2 x 5.125-inch

DT6.5LCR features a 1" Hard-Dome Tweeter and 1 x 6.5" Polypropylene Woofer. On the other hand, the 100 IW LCR5 features a 1" Inverted Hard-Dome Tweeter and 2 x 5.125" Polyglass Woofer.

Frequency Response

DT6.5LCR has a frequency range of 28-30kHz whereas 100 IW LCR5 has a frequency range of 55-23kHz. With a minimum frequency of 28Hz, the DT6.5LCR can go significantly deeper on the low side and provide stronger bass compared to the 100 IW LCR5's min frequency of 55Hz.

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

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

DT6.5LCR and 100 IW LCR5 have the same Impedance of 8 ohms but where they differ is the sensitivity levels. DT6.5LCR sensitivity is rated at 89 dB and the 100 IW LCR5's is at 90.5 dB. This 2 dB difference makes the Focal 100 IW LCR5 a more sensitive speaker compared to Definitive DT6.5LCR, 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.

100 IW LCR5 can handle a max power of 120 watts RMS, whereas DT6.5LCR has a max power handling value of 100 watts RMS, 20 watts less than the 100 IW LCR5.

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.

Verdict

No single best speaker here - they are built to different priorities, and the right one depends on your room, your amplifier and what you listen to.

AreaBetterWhy
BassADefinitive DT6.5LCR digs deeper - 28Hz against 55Hz.
Amplifier needsBFocal 100 IW LCR5 is more sensitive (91dB vs 89dB), so it goes louder on the same amplifier.
Headroomevenly matchedSimilar power handling (100W vs 120W).
SizedependsSimilar cabinet size - neither is easier to fit.
PriceADefinitive DT6.5LCR is cheaper - $458 against $598, about 23% less.

A Definitive DT6.5LCR  B Focal 100 IW LCR5
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?

Neither runs away with it - they trade advantages. Let the "depends" rows and your own room settle it. If a subwoofer is in your plans, the bass gap largely stops mattering - you would be crossing over above 55Hz anyway, so judge these on the other rows instead. Match it to your room: we rate Definitive DT6.5LCR the better fit for near-field listening and a small room, and Focal 100 IW LCR5 for a mid-size room and a large room.

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.
