    25mm tweeters (standard) or horn driven tweeters that you see in cinema's clubs etc...

    I would like to know the difference.

    Thanks in advance

    efficiency!

    A standard tweeter sprays the sound from it much wider. Energy is lost within the room as the sound is not as directed. This can cause problems with room interference as the sound from it is bounced of floors, ceilings, walls etc.

    Imagine the difference between a flood light and a spotlight.

    A horn tweeter has a 'funnel' around it to help direct the sound waves. This makes them more directional so not as problematic in acoustically difficult rooms. They are much more efficient as the sound is targeted where its needed, the listening area. For large, commercial applications, a standard tweeter will not work adequately as it is not capable of going loud enough and they can cause a nightmare with acoustics. THX specify horn designs for this reason. Horn designs will go much louder, be more dynamic, and be influenced less by the room they find themselves in.

    Most people used to the standard hifi speaker sound find horns very upfront. Once you have lived with horns for a while and realised how much dynamics are lost with standard tweeters, you'll never go back. If the design is right, a horn loaded tweeter system can be outstanding. Done wrong its dreadful!

    Kef uni Q is a good example of a horn. I use Artcoustic DF75-55's (active bass) and they are truly amazing
