Published on 01/17/04 at 15:00These speakers are active. They have the amplifiers built right in! This si great for the mobile DJ who won't have to carry around a seperate (and heavy) amplifier. Plus, the sound is rich, and smooth. They have a wide dispersion pattern, making the whole room seem to fill up with music (not just in front of the speakers). Because they have amps built in, I'm not worried about blowing these speakers.

They don't have a whole lot of Bass. I pair mine with a seperate sub-woofer when I need that extra punch. Plus, for crowds larger than 250 to 300, you really need more power. I am also concerned about the cost of repair. I have never had any problems, but if something were to go wrong with this unit, they are more expensive to replace than a stand-alone speaker, or amplifier. They are also a bit pricey, but well worth the investment!
The unit is molded plastic, and is very sturdy. It has three handles (one on each side, and one on the top) for convenient transport. The biggest thing that impressed me about the look and construction is the sheer sturdyness of it. These things are made to me hauled around, and can stand a lot of abuse!
If you are a mobile or club DJ, these are the perfect speakers for most of your applications. They are durable, sound great, and require no external amplifier. I would reccomend them to anyone who does a lot of travel with them, because they are rugged. The quality is worth the investment.

The sound is totally overrated, in my opinion. The high end is decent and fairly clear. However the low end severely lacks power and sounds harsh in comparison with other similarly priced units. I am really disappointed with these and will either have to add a subwoofer to get adequate low end, or will have to sell them and buy speakers with 15" woofers instead.
Plastic housing, seems to be fairly resistant to dings and scratches.
Way overpriced and overrated. You will need to add a subwoofer to get what you really want out of these speakers.

The overall sound of these powered PA speakers is crystal clear sound, great high mid and low range that sounds really big in the club and or night spot/ bar that you man be performing in. I didn’t particularly like the sound of the Mackie SRM 450’s when used at an outdoor even. The sound just didn’t travel well and sound as good as it does inside of four walls. This is a problem that you can have with a lot of monitors so it wasn’t something that was that big of a deal because it’s a common issue. The price of these monitors is around a standard basic price for monitors of this caliber and size. You can pull these monitors with you no matter where you take them because like I said before they aren’t too heavy to tote around with you and they can take a beating just in case they are handled roughly it wont be a problem. They sound great with live instruments and all ranges of voices from high to low. We actually had a problem finding the stands for the Macki SRM 450’s because when we purchase them they didn’t come with any. So finding the right stand that provided good balance was kind of difficult but once we did that we had a perfect sound and great looking speakers with the Mackies. Put these on your wish list.

The SRM450 is an active two-way loud-
speaker capable of extremely high sound
pressure levels, high resolution audio playback and designed to give you the
best performance of any loudspeaker in its
class and price range.
Our design goal was to build a sound re-
inforcement speaker with:
1. High precision, high output, and accu-
rate playback.
2. Very wide, smooth dispersion of mid
and high frequencies.
3. Ergonomically correct physical design
for easy transport and set up.
Through the combined resources of our
top-notch mechanical and analog engineers,
and our experienced transducer engineers
at RCF, our transducer manufacturing facility in Italy, we were able to achieve our
design goals in every aspect. The result is a
sound reinforcement system equally at home
in a concert setting, in the studio, impromptu
concerts on the studio roof, in the cinema, or
in a home theater.
The Transducers
The SRM450 active speakers feature a RCF precision 12-inch high-power low-frequency transducer and a RCF precision 1.75-inch titanium diaphragm high-output compression driver. This
high-frequency driver is mounted on an
acoustically non-resonant exponential
waveguide, providing a wide, controlled
dispersion and precise reproduction of the
critical upper mid-range and high frequen-
cies. The result is an unbelievably smooth
off-axis response that allows everyone in
the audience to experience the same high-
resolution audio no matter where they are
seated.
Each driver has been specifically designed
by our engineers and hand made in Italy for optimum performance
in the lightweight high-strength cabinet.
FR Series Power Amplifiers
To power these beautiful things, each
SRM450 includes two of our acclaimed FR
Series “Fast Recovery” power amplifiers. Our
exclusive design uses low negative feedback,
yet allows the amplifiers to maintain low distortion, high dynamic range and stability and to quickly recover when driven into clipping.
The amplifiers include the following
features:
• The low-frequency amplifier produces
up to 540 watts peak (300 continuous)
before clipping.
• The high-frequency amplifier produces
up to 150 watts peak (100 continuous)
before clipping.
• Each amplifier has its own compressor
circuit that acts when the input signal is
large enough to cause clipping, distor-
tion and excessive voice coil heat. The
compressor will automatically decrease
the input signal to a safe level. The
compressor in the low-frequency amp
works independently from that in the
high-frequency amp.
• The low-frequency amp uses a servo
feedback loop which senses the current
flowing in the woofer coil. This controls
the low-frequency response and main-
tains low distortion at high output levels.
• The low-frequency amplifier also has a
sweeping filter. This will automatically
move the low cut-off frequency up or
down depending on the amplifier
output. For example, if the amplifier is
below clipping, the low-frequency cut-
off point is 55 Hz. As it approaches
clipping, this shifts up smoothly to
120 Hz, providing more power reserves
and less distortion before clipping. This
happens quickly and continuously,
protecting the amplifer and the woofer
and reducing any noticable distortion.
The built-in electronic crossover is a
24 dB/octave Linkwitz-Riley design.
Although more expensive than other cross-
over designs, the benefits provided by the
Linkwitz-Riley design have been well docu-
mented. These benefits include:
• Absolutely flat frequency response
throughout the bandpass, without the
characteristic ripple near the crossover
point exhibited by other designs.
• The sharp 24 dB per octave roll-off of
the filters ensures that the transducers
aren’t reproducing frequencies outside
of their capabilities.
• The acoustic sum of the two driver
responses is unity at the crossover
frequency, resulting in perfect power
response.
• Our heroic engineers have worked
carefully to ensure that the SRM450
also provides perfect phase response.
This diligence has yielded phenomenal
accuracy, even if you are standing 20
feet away.
