F4

| Direct Price:  Interlude- $1,730                  
                         

  The 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 theatre 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.  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.
