The ARYA is a 2.5 way bass reflex in 45 L box. Frequency response is 41Hz to 28KHz. Sensitivity: 87.5db 1W/1M The tweeter is the SB Acoustics SB29RDAC-C000-4. The woofers are the SB Acoustics SB17MFC35-8. The low pass networks are 2nd order designs with compensation. The high pass network employs a conventional 2nd order filter with attenuation.The X-over frequency is 3KHzThe good-looking Arya is a floor standing 2½ way speaker. Arya means ‘not ordinary’ or ‘clever/smart man’ and we believe Arya is the clever choice if you want a very handsome ‘traditional’ floor standing speaker with a high performance. The drivers for Arya are the MFC (mineral filled PP cone) mid-woofers that give a tight/firm bass when tuned correctly, and a crisp mid. We are confident that PP-cones have never sounded better.With 2 x 6" you get enough quality bass in room up to about 50m2/500f2. The tweeter is the very renowned and patented SB29RDAC ring dome. It is a large dome of 29mm and the fact that it is ‘terminated’ on the top of the dome results in a very low distortion dome-type with a very ‘silent/black’ background.PARTS ONLY.
