Pluvia 7 PHD
70mm widerange drive unit
4ohm double ferrite magnet
- 4in natural blue uncoated paper cone
- Wide operating range –rolled off high frequencies for vintage tone
- Low 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
The new paper-cone Pluvia 7PHD was developed specifically for the Japanese and Asian markets, and its response balance was carefully engineered to provide a shelved down treble and emphasised upper midrange output to address specific regional requests.
The attractive paper cone, suspension and low-mass coil, wound in high-purity rectangular section copper are unique to this model, and the Thiele / Small characteristics engineered to allow surprising bass performance from a compact drive unit. The frame is the familiar, high quality Pluvia design, which may be conveniently surface or flush-mounted, and has a very open design, allowing good air-flow to the rear of the cone.
The sound balance is warm, with emphasised upper midrange, and soft treble. Jazz followers in Asia played a role in the final tuning of this driver. Those enthusiasts into vintage and mono recordings using warm tube (valve) amplification may have a particular interest in this driver.

Ryan –
I built some folded TABAQ cabinets and put FaitalPRO’s in them. My fist foray into full range and building my own cabinets. Even with lots of BSC experimentation I couldn’t tame them, they sounded shrill and sibilant. I was super disappointed with all the work that went into the cabinets only to have them sound awful.
So I took a chance, ordered these Pluvia PHD drivers, removed the BSC entirely, and swapped out the FaitalPRO’s. Even with no break-in, the PHD’s are world’s better. Very smooth, much more filled out, detailed without sounding sibilant. I like them so much I just ordered Alpair 7P’s for another project.
I’m now a Mark Audio believer, and the staff at Madisound have been friendly and responsive.

Dear Ryan
Thanks for your kind words and we are happy to support you.

I was sceptical given the low impedance and tailed off HF. However for me it was not an issue. In my Mk3 Frugal horns, they go pleasantly low and are very smooth across their frequency range, especially with vocals. Top end is there for crash cymbals etc, but curtailed say to the sibling, the metal 7HD or even the CHP 90, but a thoroughly nice driver all the same.
