Price for 1 piece

Product description

The second-generation Pluvia 7HD is designed to supersede our original Alpair 7 series drive units. It employs many of the same components, and has a very similar balance of frequency response and Thiele / Small values to the old Alpair model, packaged in the more efficient and convenient Pluvia frame.

Highlights

Vintage Gold 4’’ magnesium alloy cone

Operating range to 30KHz - very linear response

Very shallow multiform cone profile – very broad directivity pattern

Advanced low-distortion motor design

Long-stroke suspension with arrestor and progressive-rate spider

Low-profile surface-mount reinforced polymer basket

Product details

Markaudio PLUVIA-7HD Gold Full-range Woofer

The second-generation Pluvia 7HD is designed to supersede our original Alpair 7 series drive units. It employs many of the same components and has a very similar balance of frequency response and Thiele / Small values to the old Alpair model, packaged in the more efficient and convenient Pluvia frame. With a mounting depth of less than 4mm, the Pluvia may be surface or flush-mounted, and the design of the mounting legs is very open, allowing good airflow to the rear.

The low-mass coil, suspension, and shallow-profile cone are highly efficient. Frequency response extends beyond 30KHz, and the generous 4mm (1-way) Xmax and conveniently balanced T/S parameters allow 40Hz bass output in suitable enclosure designs. The sound character is neutral and highly detailed, with excellent off-axis performance. It is an extremely flexible drive unit for music, small HT and commercial AV applications, and offers exceptional performance at an affordable price point.
