Markaudio Pluvia Seven Gold Cone 4" Full Range
MarkAudio Pluvia Seven 4" Full Range in Vintage Gold (slightly Copper Colored)
Pluvia Seven Extended Full Range audio driver.
The Pluvia Seven driver is a new type of small driver from MarkAudio. While it's mechanically similar to the CHR-70 series drivers, its major design features are more advanced.
The main feature of this Pluvia is its new low-mass thin profile glass-fibre injected chassis (frame). This chassis design has taken 2 years of research and development to produce a highly damped strong frame that makes installation easy. Pluvia Seven can be either surface mounted or recessed into a loudspeaker box. The chassis mounting depth is only 3.5mm making it easy fit for either type of installation. The chassis appearance is high quality, with a professional industry finish that makes the Pluvia Seven look expensive while it remains affordable.
The Pluvia Seven features a new shape cap and revised suspensions giving it a wide range with controlled mid response to help reduce “shout,” typical of many small wide band drivers. Pluvia’s cones use the latest profiles from designer Mark Fenlon, featuring 2 new colours, Vintage Gold and Soft Chrome. Vocals on this Pluvia are clear and natural. Baffle Step Compensation (BSC) is enhanced on the new suspension layout, making this driver more effective in combatting box losses in the low range. Other new features include longer gold plated connectors for easier soldering or using clamp type connectors.
The new Pluvia Seven is an excellent high-end and multi-purpose driver. It's also suitable for many computer, Home Theatre, TV, and commercial A/V applications.

Small to medium sized speakers are usually lower power designs. The power rating is given in the technical data for each audio driver. For a reliable long service life, please operate your new speakers with care. For the first 100 hours, operate them at very low volumes. After this period, gradually increase the volume to a normal listening level. If you see the cone of the speakers making large movements, immediately turn the volume down. This will protect the speaker and your human hearing from damage. Factory mechanical defects for a period of 1 year. Excessive hard use (over-driving) and other damage caused during customer use is excluded from our warranty.
