I took the plunge and bought the Bose Compact system and generally, I am very pleased with the results
The clarity of sound from the system is exceptional and the available volume is more than adequate, for the types of gigs at which I play.
I spent quite a bit of time doing comparisons between the sounds from the KN7000 alone, and the Bose system (with the KN7000 audio muted) and as John mentioned, I felt that the mid-range was just lacking slightly. The bass was smooth and full bodied and the treble really clean and crisp but there was just 'that something' - 'Warmth' - missing from the Bose system, when compared with the sound from the KN7000.
I experimented with the KN7000's own EQ system but that did not really provide a solution. When I play at gigs, I like to keep the KN7000's own sound system active, even though I may be using an external amplifier. Ideally, I want the external system to sound the same as - or better than (LOL) the KN7000's system. The problem with using the internal EQ system is that it also alters the KN7000's sound (as expected) but this is not what I was trying to achieve. I am quite happy with the sound from the KN7000, without any EQ modification and only wished to add some EQ to the Bose system. So, it seemed that the solution was to insert an external EQ module between the KN7000 and the Bose system.
I did consider the Bose T1 ToneMatch Audio Mixer, but thought it was a bit 'over the top' for my application, and at US $500 just too expensive......
So, I bought a Behringer EQ700 7 Band Graphic Equalizer (£21 / US $33), which is in the form of a foot-pedal, and with just slight adjustments to the mid range, it has made all the difference to the 'warmth' of the sound from the Bose system........
So, I am now one Happy Bunny
