Well, I am around here somewhere.
Everyone has their own preference/taste, and as usual some people hear things differently. Also some
people will speculate, because the speaker does not look so-called big enough.
The Cambridge does a nice job below 100 hz - the speaker does not die around this frequency. The woofer
can really be called a 5 inch woofer - from inside the woofer frame to the outside edge of the surround, it
is 5 inches. The speaker is punchy, and not boomy, muddy or wooly sounding - the bass is strong to 60 hz.
However, there is no guarantee that the Cambridge will be enough speaker for you.
I prefer the Cambridge over the Pioneer towers and bookshelf - over the Polk RTi and Monitor/TSi speakers
and the Infinity Primus speakers, and also over the HTD speakers.
The Pioneer towers will have lower bass - and can/will sound bigger on some sources - however, when the
Cambridge is placed on top of the Pioneer towers, they hold their own on a lot of sources. The Cambridge
is more clear/open and lively sounding to me, and easy to listen to, without ear fatigue.
I can not speak for HSU or how they may compare - however, a subjective review here >
The 1713 can handle the Cambridge - however, a little more power can/will help
