Presentation:

The MS400 is a yamaha powered speaker in abs.
It contains two amplifiers, 300w for the 100W for the serious and acute.
They use technology EEEngine Yamaha. Translate high power (400W) and low power consumption (150W).
Yamaha must use a G or H polarization for his amps. In practice it works very well even if it lacks punch compared to the traditional amplification. The food is classic with a big transformer bracket, diode bridge and condos. A switching power supply would have been preferable for the weight (-5kg) but the price is not the same ...

This is not a pure product Yamaha "made in japan" simply because it&#39;s Inter M which designs and manufactures the chamber as a very large part of the sound produced by the famous Japanese (and other brands such as EV / Dynacord , mackie amps for ...).

The Hps are Eminence: A beautifully crafted 38cm Neodymium is a model of order.
psd an engine 2002 of conventional construction (not neodymium) against well known.
Reel 2 &#39;output 1&#39;, 105dB performance. It does not rise above 15Khz.
The frequency response ranges from 80Hz to 15kHz for a spl of 124dB.

The whole thing is molded ABS construction with serious, even if the plastic is easy to scratch, and weighs 24 kg It embeds a mini mixer with microphone input and line input with three doses (xlr male / female and TRS) connected in parallel (very convenient, they can be used to distribute the signal to two destinations, one or two MS400 for example).
There is a way by volume, for a general and a serious basic eq (-10dB to 0dB) and acute (+ / - 10dB).

Background:

It has been five years since I use them. I have four and two drummer. Another friend was also guitarist in a pair. All that to say that the animal has been tested extensively. We use two front feet and four on back "foot bath".
I turn to dances from 100 to 400 people either bagpipe band (drums, accordion, sax, keyboards and two songs), or evening wedding for a more pop (two keyboards and vocals). I also used for recitals and other wedding mass. A versatile front / back.

At the time we listen to everything that was done.

Behringer B300: They have excellent products (rev2496, ultracurve2496, DCX2496), but this is a disaster! Worth avoiding ...

Mackie SRM450: + Many potato (good amp), Grave generous (despite 31cm)
- Price therefore (at the time), mid / high bizarre. (They also dropped the flag to diffraction from the other models in the range ...)

RCF ART 500A: + exceptional quality of HP (15/554k and N850) and amplifiers. good construction
- Weight (38kg), lack of finesse in the acute (normal for an engine 2 &#39;)

JBL EON 15: + low weight, size
- Prices, 38cm molded with the front (in case of problems must be changed at all), its anything to do with any medium and most acute piezo ...

Our choice is ultimately focused on the Yamaha MS400.

Situations:

What tipped the balance towards the MS400 is the quality of sound reproduction.
Compete at the time, it projects the sound is closer to that of the stereo sound system.
We work with acoustic instruments (including voice) and the medium must be acute as faithful as possible.

The overall sound is very good, it is comparable to an EV SX300 (a friend has a pair) for a serious spl équivalent.Le does not drop below 80 Hz (like many other speakers "broadband"), this which makes it usable without any problem but one (classical) for the "real serious" subwoofers will be necessary.

MS400
the +: Price / performance excellent playback quality, good spl, indestructible
the -: lacks a bit of fishing for the amps, the plastic is easily mocked, not tilted back enough (you have to put a shim below), models are now lighter (but more expensive too ... )

Appraisal:

A very good product, clearly the best choice at the time, with absolutely no reliability problems, the MS400 is indestructible. Today, there are other choices. I think particularly with the new art of Rcf that are really a synthesis of what is the best, the small-definition 310A is excellent for weight (14kg) low.
The Mackie sa1530/sa1232/sa1532 are very nice but also heavy and bulky.
Today, to use classic front / back, I would definitely do it again this election, especially given the bargain price (400th), but I change the concept and scope with the Bose L1. We bought four, I will give my opinion in some time ...
