General Description
With this dedicated subwoofer line up from Jamo we wanted to achieve several
goals.
We wanted a subwoofer line up with the best ever performance per $ and we
wanted it to be able to match a variety of different speaker solutions on the
market, including Jamo of course.
Making a dedicated subwoofer line up, instead of making designated
subwoofers to a specific speaker series creates e few challenges.
One challenges being to create a design and performance capable of matching
basically all speakers in the marketplace.
The design should be modern and “independent”, yet discreet enough to
match both different speakers and different interiors.
Another challenge for the development team was to optimize every “link in the
chai” to achieve the best ever performance. We wanted a subwoofer line up
capable of achieving high sound pressure levels (SPL) without compromising
the sound quality. It is quite easy to make a subwoofer play loud – but it is a
challenge at the same time to maintain precision and musicality.
This turned out to require development of completely new drivers and new
amplifiers as well as a new approach to manufacturing the cabinets, since it was
clear very early in the development process that a new way of bass reflex
loading (
S
lotted
B
ass reflex
P
ort) had to be invented in order to keep the
cabinets as compact as possible.
The Products
SUB 250
SUB 250 is the smallest subwoofer in the line up. But do not let this deceive you.
With an long-throwing 8” subwoofer driver
housed in a Slotted Bass reflex Port cabinet
together with an BASH amplifier capable of
delivering over 250 W peak power this
subwoofer is a really strong performer
capable of deliver bass down to 30 Hz (-
6dB). The SUB 250 has a very flat frequency
response (see figure x) making it capable of
playing bass notes in a very convincing way
compared to many conventional bass reflex
subwoofers. (see picture 1).
