What speeds are needed for different services?
Different music streaming services have different recommendations depending on the
audio file sizes involved:
Service
Tidal (Master tier)
Amazon Music (Ultra HD)
Amazon Music (HD)
Deezer
Qobuz
Note that these are minimum dedicated speeds recommended by the services
themselves.
What this means is that your total network bandwidth must exceed the total
bandwidth requirements of all devices on the network. If your active network devices
need more bandwidth than what is available, then you may experience slower speeds,
reduced performance and dropouts. This is not as much of a problem for web
browsing or file downloads (except for being slower) but is especially problematic for
music streaming.
My test score is a lot lower than what I pay my ISP for. Why?
The bandwidth provided by your ISP (Internet Service Provider) is advertised as 'up
to' as this is the maximum bandwidth you can expect coming into your network. This
can be affected by many things such as the quality of the provider's cabling, 'Fair Use'
clauses in the agreement and the amount of people accessing the same server.
But even if you get the maximum advertised bandwidth from your ISP, the home
network may be creating a bottleneck. Major factors include interference, obstructions
and distance between the router and device. Even time of day can have an effect – if
more people are using the internet in your area, that can reduce bandwidth. However,
there are some simple things to try that can really help improve your test score.
Why is the score lower than other tests?
Internet connectivity tests are often optimised to give you a theoretical 'best scenario'
speed and can be a good indicator for what your ISP is providing but will not tell you
specifically what bandwidth your KEF speaker system will be able to take advantage
of. The KEF Connect speaker connection test more closely represents what happens
when using the speaker system normally:
Minimum Recommended Bandwidth
2 Mbps
5-10 Mbps
1.5 – 2 Mbps
5 Mbps
10 Mbps
