This is a review and detailed measurements of the Paradigm Cinema 100 CT HT speaker. It is the mains (left and right) of a 5.1 package which was kindly sent to me by a member and costs US $1099 (for all six speaker).
The Cinema 100 is elegantly finished in its little package:
There is a removable stand that also routes the speaker wires to the small terminals in the back. It is an attempt to hide the wiring on the back in case the speakers are exposed.
Measurements that you are about to see were performed using the Klippel Near-field Scanner (NFS). This is a robotic measurement system that analyzes the speaker all around and is able (using advanced mathematics and dual scan) to subtract room reflections (so where I measure it doesn't matter). It also measures the speaker at close distance ("near-field") which sharply reduces the impact of room noise. Both of these factors enable testing in ordinary rooms yet results that can be more accurate than an anechoic chamber. In a nutshell, the measurements show the actual sound coming out of the speaker independent of the room.
I performed over 800 measurement which resulted in error rate of roughly 1% to 2%.
Testing temperature was around 64 degrees F.
Reference axis for measurements was the center of the tweeter (by eye). Grill was not used in either measurements or listening tests.
Measurements are compliant with latest speaker research into what can predict the speaker preference and is standardized in CEA/CTA-2034 ANSI specifications. Likewise listening tests are performed per research that shows mono listening is much more revealing of differences between speakers than stereo or multichannel.
Paradigm Cinema 100 Measurements
Acoustic measurements can be grouped in a way that can be perceptually analyzed to determine how good a speaker is and how it can be used in a room. This so called spinorama shows us just about everything we need to know about the speaker with respect to tonality and some flaws:
The frequency response error is quite obvious to see. It first droops but then rises starting at 1 kHz until it finished in a large tweeter resonance around 15 kHz:
Early window mimics the same for good and bad:
Final predicted in-room response tells us what we can already guess with too little bass (this is a sealed box) and too much highs:
Distortion is under control although that is mostly because the woofer is not allowed to play low:
Directivity scales with frequency which means there is not much control:
Vertical directivity is better going up than down so don't put the tweeter below your ear axis:
Finally, here is the impedance and phase:
Listening Tests
I listened to the Cinema 100 without its sub (which I did not have). As expected, it sounded tinny and bright. Attempts at EQ were not successful. Likely needs to be tuned with its sub playing at the same time.
Conclusions
I like to evaluate speakers as stand-alone units without a sub. Here, it is impossible to do since a sub is supplied normally with the unit. Even so, it is clear the company wanted to let the highs play brighter as to sell better in a showroom. How critical do we get in this class of speakers though? I don't know. I let you decide. I have no recommendation one way or the other.

As always, questions, comments, recommendations, etc. are welcome.
