F4 is the perfect comprise between size, performance and cost.
It has the same sense of power and authority as the more expensive
Interlude, and is capable of an amazing performance, in both music
and in home theater applications. The 8" mid bass is the
same driver used as a bass in the Eclipse and as a mid/bass in
the Interlude. It is stunningly fast with a spectacular dynamic
range, giving a performance which will satisfy anyone who wants
a big sound, but does not have the space or decor to suite a larger
speaker. Every attempt has been made to retain as much of the
stunning performance of the Interlude as possible, whilst costing
less. In keeping the price down as low as possible, savings have
been made by using 1.2mm wire in the Inductors in place of the
Interludes 1.7mm. Quality Solan Capacitors are used instead of
the prohibitively expensive Hovland MusiCaps. The tweeter uses
a hefty 0.5 Kg magnet instead of the Interludes massive 1.4 Kg.
Most of the cost saving was made by deleting the solid lipping,
rounded corners of the more expensive models. Because of these
changes the F4s are not quite as beautiful, do not quite have
the inner detail or airy transparency of the Interludes, but the
bass and lower midrange is the same. As a value for money package,
it is unsurpassed.
The above specifications show why these speakers are capable of such extraordinary transient performance for such a relatively small speaker and yet reveal such intimate detail in the music. This fidelity is possible due to the fine tolerances and light weight of the driver voice coils. This minimal compromise design allows the natural life and excitement of the original live performance to be faithfully reproduced.
It is vitally important in the accurate reproduction of music, that there is no dynamic compression to strangle the music during transients. The transient ability of the F4s and their ability to play accurately at whatever volume the music takes them, is unsurpassed.
