Digital Cameras Photo Reviews of Creative TravelSound 200 Portable Speaker SystemCustomer Review: Well designed portable speakers Summary: 5 Stars
A detailed review from an audio guys point of view.
This is an impressive set of amplified speakers considering their small size. They provide a nice, full sound covering all the notes from the highest high down to about 150Hz in the bass region just like the specs say. 150Hz is not low bass by any means but the overall sound is surprisingly accurate and clear.
Songs (or voice recordings) sound just like they should with no problems. The amp itself is completely quiet with no coloration or hiss at any volume.
2 watts/channel (4 watts total) is more than enough to fill the average room with sound. Of course there is not a lot of bass but their is enough for songs to sound natural.
Some tests with a Fluke 83 multimeter showed that it only takes about .2-.4 watts to equal the output of my TV at an average listening level. Since it has 4 watts to work with it can crank pretty well putting out clean sounds up to a maximum of 97dB in my listening room. It can go slightly louder on songs with reduced bass content but that is the average limit on a variety of music which is just fine for a unit of this size.
I did some frequncy response tests with an audio meter set to C weighting which samples the full audio range.
A sine wave function generator was used as the input to the TravelSound 200. Readings were taken at 12" rather than the usual 3' used for large speakers.
Relative output vs frequency chart, 0dB reference at 400Hz:
10Khz 0 dB
5Khz +3 dB
1.5Khz +2 dB
1.0Khz +1 dB
500hz +1 dB
400Hz 0 dB
300Hz 0 dB
200Hz -1 dB
150Hz -3 dB
100Hz -8 dB
90Hz -12 dB
80Hz -15 dB
70Hz -25 dB
That shows a nice flat response down to 150Hz where it drops off quickly. There is a little output even at 100Hz but it's basically all done at that point which is expected. The little speakers try really hard and get moving a fair amount when driven hard.
Maximum Output vs Frequency chart:
This is not the same as frequency reponse shown above. This shows the maximum volume at various notes limited by the speaker moving past it's linear range (distorting) or the amplifier clipping the peaks of the notes.
Frequency - Loudness:
10Khz Ouch! Hurts ears.
1.0Khz 101 dB
500hz 100 dB
400Hz 100 dB
300Hz 99 dB
200Hz 96 dB
170Hz 90 dB
150Hz 88 dB
130Hz 85 dB
100Hz 77 dB
90Hz 76 dB
80Hz 75 dB
70Hz 73 dB
60Hz 70 dB
This shows the speaker system as a whole has signiicant output from 200Hz and above.
Current Draw measurements (to determine battery life)
0mA when off.
17mA at Idle
50mA at low music level., volume at 2
100mA average listening level, volume at 4
300mA This is quite loud ~ 95dB volume at 7
500mA At full volume.
Using 2500mA-Hr rechargeable NiMH AA's I would expect:
50 hours of battery life at low volume
25 hours at medium
4 hours at full volume.
(It should run about 6 days if you forget to turn it off) :-)
Formula example: 2500mA-hr/100mA = 25 hours.
The Creative Labs Travelsound 200 sounds very good for most applications requiring medium sound from a small package. I can honestly recommend it and I many years experience in audio and electronics to base that on.
It can be connected to any audio device that has a typical stereo 1/8" (3.5mm) line out or headphone level output such as casstte walkmans, tape decks, CD players, MP3 players, computer sound cards, etc.
This particular package does not include the AC adaptor. The unit itself has a 5V DC jack so one can be added.
Description of Creative TravelSound 200 Portable Speaker SystemCompact, lightweight, yet affordable, Creative TravelSound 200 is the perfect portable palm-sized speaker with built-in high precision Titanium micro drivers to deliver crystal clear audio playback. Suitable for listening to music CDs, MP3 songs or even watching movies on your notebook. Portable option with 4x "AA" batteries or optional universal power supply adapter (sold separately). Comes with an Audio Normalizer switch, which reduces excessive loud songs to average volume level - this problem is common when ripping MP3 music. The Wide Stereo Effect feature enhances your audio listening experience by expanding the sound stage.
