Auditioned the Mirage MX 5.1 with 6" sub. Would require suggestion from forum members does a 6" sub with 2 passive radiators really good?


Also what is this Omnipolar technology which Mirage claims sets them apart from rest.

Regards

Also this system is quoted higher than

1. Mirage Nanosat 5.1 which comes with 10" Sub
and
2. Mirage HGB which comes with 8" sub, But larger centre. Same satellites.

They claim the MX has better quality, did not have time to compare the systems. They did not sound convincing at all.

Today, you have three speaker formats that are accepted, and a new one from Mirage.

The formats are direct radiating, bipolar, dipolar, and the new one patented by Mirage called Omnipolar.

In direct radiating, the speaker cabinet has a set of drivers that push the sound waves in a single direction, usually forward. The sound waves move like a beam of light, a cone starting from the speaker and expanding towards the listener. This is the most common format and the drivers are positioned as an array in the front of the cabinet. In this format, there are two discrete sound signals and a sweet pot which, usually, is where the two cones merge.

In Bipolar, also introduced by Mirage in 1987, the cabinet has two set of drivers - one set mounted on the front side and firing forward towards the listener. It also has a second set mounted in the rear of the cabinet and firing backwards. This format is used extensively by Definitive Technology and is supposed to create a 360 degree diffusion of sound. The forward firing sound is duplicated by the rear firing drivers. The rear firing sound is reflected off the rear and side walls. Added together, these sound signals are supposed to give you a more enveloping sound stage. There are no discrete sound signals, and there are no sweet spots. The speakers driving both forward and backwards create a large sound stage in which the voices and instruments can be differentiated.

Dipolar speakers are also similar to bipolar, excepting for one major difference. In bipolar, both sound signals are in phase with each other. In Dipolar, the second sound signal is out of phase with the first sound signal. The 'rear' speakers generate an inverse sound signal. This is supposed to create a large bass response. Dipolar speakers are popular in surround sound where the drivers are kept on two sides of a rough triangle. Some manufacturers make dipole speakers that can keep both set of drivers in-phase or out of phase with each other. When they are in phase, they simply send the sound signals in two directions.

Omnipolar, as the term omni suggests, attempts to disperse the sound signals in a full 360 degree pattern. The speakers have two set of drivers. The woofers are placed in a conventional manner inside the cabinet but at a slight angle pointed towards the top of your head. The tweeter and midrange drivers face vertically upwards. These drivers are backed by convex reflectors that disperse the sound in all directions. When you send sound signals in all directions it becomes difficult to pinpoint an instrument or a voice. To solve this, Mirage uses a combination of off-axis and on-axis sound dispersement that kind of nullify each other. This is supposed to give you a larger sound stage as well as the ability to pinpoint the voices and instruments.

Mirage is not the only company to make omnipolar speakers. There is another company I know of called Duevel (model - Planets) (http://www.cd-komzert.com) that also makes omnipolar speakers. In this, the up firing drivers have a small stainless steel ball over the drivers that disperse the sound in all directions.

Cheers
