Joseph Audio Pulsar2 Graphene Bookshelf Speaker (Pair)
The Joseph Audio Pulsar2 Graphene establishes a new benchmark in mini monitor performance. It truly conveys the scale of a much larger speaker, combined with the speed, precise imaging and resolution that “mini” fans have always prized.
The Pulsar2 Graphene utilizes the same ultra high resolution tweeter found in our top of the line Pearl3, seamlessly married to a newly developed precision cast Graphene coated Magnesium cone long throw woofer. Dual sets of Cardas patented binding posts permit bi-wire or bi-amplification.
True 8 Ohm
System impedance indicates whether the speaker presents a "hard" or "easy" load on the amplifier. True 8 ohm speakers are less amplifier and cable sensitive, and partner well with a broader range of amplifiers, including tube designs.
Crossover
Constructed of specially selected components, each network is tested and individually calibrated to a high degree of precision, resulting in a virtually perfect match to the original design prototype.
The steep filter slope ensures good acoustical behavior in the crossover regions, with a minimum of acoustical interference, along with low distortion and wide dynamic range. Driver acoustic responses are in-phase throughout the crossover regions.
Frequency Response
The Pulsar delivers a very smooth and even response over a very broad listening window. Unlike conventional low order crossover designs, the speaker retains its sonic balance over a wide angle both vertically and horizontally. This results in a higher level of fidelity than a simple on axis measurement can reveal.
