Excellent full range studio monitors from the mid ’90s. They sound crystal clear and precise, with an excellent low frequency extension – which a lot of modern studio monitors don’t cope with without adding a subwoofer. I’ve mixed on them for years and they have never let me down. Here’s some stuff from their literature. 

 

 

 “ABSOLUTE PHASE LINEARITY – A true phase linear design prevents phase lag to ensure that all frequencies reach your ear at the same time,essential for accurate monitoring. Many designs attempt to overcome the problem by playing with the physical alignment of the drivers, invariably leading to phase lag at low frequencies. In contrast, Absolute 4Ps achieve true phase linearity by the use of Spirits active VCS crossover which electronically aligns the drivers. 

 

 

ABSOLUTE SOUND QUALITY – To achieve Trevor Strides design brief of a natural, uncoloured sound, 4Ps use bass cones custom-made from HD-A (High Definition Aerogel). This remarkable new composite exhibits very high internal damping, high rigidity and low mass. Being lighter and more rigid than standard paper designs, 4Ps cones are at least 2dB more efficient and very low in colouration. Furthermore, Trevor chose ferro-fluid cooled soft dome drivers instead of metallic tweeters which can create unwanted spurious HF resonances. Flat response is maintained off-axis by the newly designed tweeter face plates, and the edges of the substantial 18mm MDF cabinet are radiused to help prevent HF refraction and interference. 

 

 

ABSOLUTE POWER – Two 100 watt amplifiers in each enclosure make Absolute 4Ps the most powerful active monitors in their price class – but that wasnt the prime objective. The use of an active VCS crossover, coupled with dedicated drive to the LF and HF units, enables the frequency response characteristics of the system to remain flat at all levels. Built-in protection circuitry also works together with the amplifiers to provide a constant safeguard. A switchable 40Hz High Pass Filter allows accurate, high level monitoring of bass-heavy music signals as well as simulating the response of typical hifi speakers to facilitate home studio mixing.

Far too heavy and precious to post. Collection in person only unless you can arrange something yourself.
