ProAc's latest the studio 148 is a narrow columnar design with a stabilising plinth and bass port pre-drilled for adjustable spikes.
The beautiful and real wood veneers are impeccable making it suitable for all types of room design. There are 3 drive units in each enclosure, the two 6.5 inch units cover bass frequencies but each one has been mechanically tuned to cover mid frequencies.
To improve dispersion the upper bass driver has a phase plug whilst the lower unit has a ProAc open weave cap. This gives the 148 tremendous bass power and depth with a clear precise mid range. The bass drivers crossover to the ProAc 1 inch silk dome tweeter used in many other ProAc models.
The bass drivers are loaded by a port in the bottom of the cabinet and through the plinth. Spikes are used to raise the cabinet allowing air to move under the enclosure and through the port. Improvements can be heard in all areas from a tight, cleaner and extended bass through a detailed mid-range with a sweet and detailed high frequency, the 148 also has a large spectacular sound stage with pin point imagery.
The studio 148 comes in a variety of real wood veneers and is above average for efficiency, meaning the use of small high quality valve amplifiers and transistor amplifiers.
