Alcone Dirac XT

The Dirac was developed by request of many customers who asked for a Langrange XT in the typical D'Appolito arrangement. This loudspeaker is ideally suited for both hi-fi and home cinema.

The 2 way bass reflex, floorstanding Dirac XT is an Alcone-Scan Speak kit consisting of a ring radiator Scan Speak R2604/832000 and two magnetically shielded Alcone AC5.25 HES.

The Dirac XT in an older version with Vifa ring radiator was reviewed in Klang + Ton 4/2004, with an excellent result.
 

The Dirac XT features the following characteristics: well matched bass well balanced sound and excellent imaging high transparency warm and pleasant bass beautiful, slim design (height x width x depth): 110 x 23 x 28 cm Technical data: frequency response: 39-30 000 Hz (-8dB) crossover frequency: 2700 Hz SPL at rated input: 91 dB (2,83V/1m) impedance: 4 Ohm The Alcone Dirac XT kit consists of: 1 x Scan Speak R2604/832000 2 x mid / bass drivers Alcone AC 5.25, 8 Ohm, shielded 1 x bi-wiring terminal with gold plated brass binding posts 2 x bags damping material (1/2 for upper section) 1 x crossover - as kit, see below 18 x screws 4 x 20 mm foam sealing tape for drivers 4m cable for internal wiring, 2x1,5 mm2) 1 x bass reflex tube HP 70 description and building instruction

The crossover consists of: air core coil 1,0 mH / 1,3 mm 1x air core coil 0,15 mH / 0,7 mm 1x air core coil 0,39 mH / 0,7 mm	Mundorf MKP capacitor 5,6 μF / 400 V Mundorf MKP capacitor 1,0 μF / 400 V 2x Mundorf MKP capacitor 8,2 μF / 400 V 2x MOX4 resistor, 0,33 Ohm (orange-orange-silver)
Picture left: frequency response. Extremely linear, a slight reduction of mids to lower presence was not necessary to implement.

Sound description: Although the Dirac's design is quite different to the Pascal's and deploys a totally different crossover (capacitors in the high frequency circuit) they both sound absolutely the same. The Pascal, however, is a more forward, can take considerably more power and shows a higher sound pressure level.

Dirac XT Ultimo

and for customers who want just the best:
- silver plated cables for internal wiring,
- 2x Mundorf MCAP Supreme for high frequency circuit, 2x Mundorf audiophile MCAP
- 2x CFC copper foil coils and 1x baked varnish coil,
- 1x fleece as damping material and 4x Bitumex (self adhesive sheets with bitumen) for the side panels.
- the change in coils requires resistors (MOX10) of 0,47 Ohm.

Dirac XT Satellite and Centre

Technical Data:

frequency response: 50-30 000 Hz (-8dB)
power handling (continuous/programme): 160 / 240 Watt
crossover frequency: 2700 Hz
SPL at rated input: 91 dB (2,83V/1m)
Impedance: 4 Ohm

The Alcone Dirac is ideally suited for surround sound system since: - all 5 systems show the same sound characteristics - the bass response (can not be located) is the only difference between satellite/centre and front speakers .
- the Dirac is full fledged speaker whose bass response is more than adequate for demanding surround sound systems. - this range of speakers shows an excellent price/performance ratio (many reviews in Klang+Ton) and features magnetically shielded drivers.
