Thump 12a Review.
recent advent of Class-D fast recovery amplifiers, together
with lightweight neodymium magnets has advanced speaker technology
to the point where powerful full-range lightweight speakers
are a reality.
the Mackie Thump range. Consisting of the 12” Thump-12a (Reviewed)
and the 15” Thump-15a, these economy speakers sure pack plenty
of punch for their size and cost.
units offer 400watts peak power (200RMS) with 300 to the 12”
inch woofer and 100 to the 1” tweeter.
is of tough plastic with recessed handles both on the sides
and the top. This makes it a breeze to carry two 11.6kg units
in one load-in trip to your venue. The Thumps are pole mountable
and can also be used as monitor wedges thanks to their angled
provided are XLR in; which can accept input from a mixer or
directly from a microphone, and XLR through, which is useful
for daisy chaining other units such as monitors fed from an
auxiliary feed. A three band EQ section provides useful tone
shaping, whilst a level control is also provided. Thermal
shutdown protection is also standard.
that we have covered the specifications, let’s look at the
sounds. These speakers put out 200 watts RMS, have a range
of 57- 20 Khz, and put out 117 DB at 1m. Translated this basically
means that they will be able to handle the low end pretty
well while maintain nice crisp highs, at a decent volume.
have personally I have a pair of the Thump 12a’s which normally
cover monitor duty for my band. They perform this role very
well with the vocals coming in very clear, and enough low-end
so we can monitor our other instruments. We put everything
into our mix and use midi tracks for drums and other instruments,
so monitoring is very important to us. These speakers certainly
have enough power and clarity to deal with this situation.
I have also taken them out to a solo DJ gig and again no problem
playing pre-recorded tracks from CD players or laptops using
only this to note with these speakers that has also been mentioned
by many owners is a small digital hiss when high pitched,
low volume sounds fade away, however during normal use this
colleague of mine in Oklahoma who runs a PA rental business
also uses them for small to medium events, although he very
rightly says that the Mackie SRM450s outperform the Thumps
by a long way as they push out 400 watts RMS. Then again the
450s even though they are roughly the same size are double
the price and double the weight. He has also tested the Thump
15a and these have more pronounced handling in the low end
department due to the bigger 15” Speaker.
thing that would also be useful actually would be for all
companies to standardise on which “watts” to quote Peak or
RMS. Even Mackie themselves quote 400 peak for the Thumps
and 400 RMS for the SRM450s, big difference !
summary a great set of speakers, if you are looking to cover
small to medium venues or use them as monitors.
