- Boston Acoustics BA7500 Speaker System User Manual. Of 6 Digital BA7500. 5.1 Dolby ® Digital Surround Speaker System. Can Boston VR40. Jan 12, 2013 I have a Boston Acoustic Digital BA7500G surround speaker system. On the last computer I had, I had to make sure that it was set to digital.
It is important to measure the performance of the system based on itsspecified uses and not out of context, ie. as a Desktop multimedia/theatre system, nota home theatre system. The system was built to include 4-channel gaming, Desktop theatre (Dolby Digial 5.1) audio, and music. Some reviewshave completely missed the usage as a DD 5.1 system, and the inbuilt AC3decoder, which eliminates the need for a seperate receiver or decoder.When considering the price of the system, the cost of factoring in a hardwaredecoder should be noted. If hardware DD decoding is not an issue, the US$100cheaper BA4800 should provide similar performance for less cost – the BA7500in fact uses the same subwoofer as the BA4800 and part of what you arepaying for in the BA7500 is the aesthetics of the slim speaker design.
It is also notable that Boston Acoustics has declined to provide thesystem power output levels. Wattage does not always tell the quality/volumeof the system, basically bigger is not always better. For example the LogitechDSR-100 system offers a 100-Watt system, but this is at a significant “upto” 10% THD (Total Harmonic Distortion). So instead of competing on a poweroutput basis, Boston Acoustics has chosen to provide SPL (sound pressurelevel) outputs, which in the case of the BA7500 is at a significant 107dB.In a nutshell, “they are loud”. As noted further on in the review the speakerscan produce an extremely loud output with no distortion.
Overall sound quality:
I was particularly impressed with the upper range of the speakers,considering they are without a separate tweeter. The high range instrumentalssuch as cymbals were easily audible with excellent clarity and quality.
The midrange was reasonable, but felt slightly lacking, and didn’tsound as rich as I would have prefered.
The bass and LFE channel is provided by a 6 ½ “ bandpass subwoofer' (Atwo-chamber cabinet - One sealed, one vented; which according to BostonAcoustics will “create a sharp roll-off above and below its operating range,minimizing the need for an electrical filter or crossover”). The subwooferproduced crisp, tight bass, which when turned up to the higher levels couldproduce pure boomy effects enough to get the walls vibrating.
When listening to the whole frequency spectrum blended together, the system couldproduce the full range with easily distinguishable bass – midrange – treble. However the system seems to accentuate the upper-midrange frequencies,and excels at reproducing the vocals with incredible clarity and accuracy,but at very loud volumes may produce peaky, over-enhanced highs, whichmay start to sound harsh to the ears. Conversely, the lower-midrange seemsslightly weak compared to the rest of the sound range. In addition, thesystem as a whole lacked cohesiveness at times between the LFE and satellites,most likely due to the slightly below par lower-midrange. At times theaudio did not blend in seamlessly at the frequency around the crossoverpoint, and could be distinguished as coming specifically from the satellitesor the subwoofer.
Overall in summary what I noticed about the system was an astoundingperformance and detail, especially in the reproduction of the vocals. However, as mentioned earliersome lower-midrange sounds such as guitars were still audible and clear,but were slightly weak compared to the rest of the frequency range. Thelisted frequency response for this system is 45-20000hz, which will theoreticallyreproduce all but the lowest frequencies, including the double bassoonand a few organ notes.

Pushing the volume of the system up higher only made them sound better,and I only detected a trace of distortion at the very maximum volume setting,(which in all fairness, when used in a desktop setup will be enough tomake you go deaf). The speakers also managed to keep their audio quality,without starting to sound hard or grainy at high volumes. The subwooferdid however start to fall behind the speakers at moderately high volumes– this is noting however that the room was noticeably shaking and the speakerscan output a max SPL of 107db. When testing the system at high volumesI noticed some “rattling” noises, but upon further investigation foundit out to be caused within the walls themselves rattling!
Speaker hiss when the speaker volume is turned up with no actual soundoutput can also be an issue. Either the amplifier or the sound card cancause this. With analog output some hiss could be heard from the speakerswith the master volume past about 50%, but with digital output could goall the way up with only barely audible distortion. This would tend tosuggest that the problem is to do with the sound card rather than the amplifier.
The speakers also sound like more of a non-directional sound system– this means the exact location of a sound is not easy for the listenerto pinpoint. I feel this creates a more “immersive” overall feeling, whichmay be better for effects such as an object passing through you in certainDVD movies, but not so good where exact locations of a sound source isrequired, such as in a FPS game where the more accurate the ability topinpoint source of an enemy the better. This is however a subjective topicand different people may hold different views.
