Details Review

Design:

The Definitive Technology Demand Series D11 has modern looks. It is made of high quality MDF and has aluminum front baffle. We love the white color other than the usual black one. Also, removable acoustic transparent grille is available. Place them as on tables, desks or stands. It also comes with integrated rubber pads to improve stability.

Performance:

Definitive Technology Demand Series D11 are full-range speakers that can produce room-filling sound. The tweeters deliver crisp highs and precise mids. Offset tweeter is designed to lower any unwanted diffraction. It has well-built crossover and the manual suggests to set the receiver at 60Hz.Allow the speakers to go through 30 hours of break-in time. The speakers can produce warm and non-fatiguing sound.

It has clear and natural highs and very precise midrange. The top passive radiators work on producing deeper bass. Low ends are great and powerful with adequate oomph. You can connect sub from Definitive Technologies brand or some other brand like SVS, Polk, etc. We suggest to use a powered sub for tighter bass response. Although they are bookshelf speakers, they sound like floorstanding speaker.

If you want to improve the bass and treble, go for bi-wiring or bi-amping. Speaker placement process is written in details in the manual. After placing, you can change the position and see how the sound works for you.

Connectivity:

The connectivity of this passive speaker will depend on the amp ports. It supports bi-wiring and bi-amping with amplifiers.

Use case:

Definitive Technology Demand Series D11 is best for mid to large sized rooms. Create a 3.1 system and connect the speakers to your TV. Or, connect it to PC, turntable, etc. It can handle music genre like Jazz, classical or tracks that have too much instrumental sounds. Movie sounds, vocals and effects are handled very well too.

Compatible device: 

You can pair it with Sonos amp, Parasound Halo amp, or from any other brand. Definitive Technology Demand Series D11 bookshelf speaker can be connected to floorstanding loudspeakers (D15/D17), bookshelf loudspeakers (D7/D9), and a center-channel loudspeaker (D5C).

Ease of use:

This depends on the amplifier connected to the speaker.

Cost:

The cost of Definitive Technology Demand Series D11 isn’t cheap. However, we think the cost is compensated with brilliant performance.
