    Bottom Line:   
    I have to agree with the previous reviewer's comments about the versitility of these speakers. I currently have only one of these that I use to provide both rear center channels in a 7.1 system. I have a smaller room so the ability to use a single speaker to provide two channels is a major plus for my application. Although I never have tried any of the other speaker settings (monopole/dipole), I can see that the speaker could be extremely versatile and easy to tailor to a personal listening preference. The sound quality is great! The speaker blends well with all of my other speakers which are also from the Infinity Beta Series (50's as fronts, C360 center, and 10's as left/right rear).

    Bottom Line:   

    I spent a lot of time hunting around, researching and getting annoyed, and I realised that there are really no surround speakers that give you what these things give you. Here's why I reckon my new Infinity ES-250's are so damn great...

    * Great looking (high spouse-approval factor)
    * Available in black or white
    * Protective metal grilles mean no kids or guests putting their hands through the speaker diaphragms. Minimal effect on sound quality.
    * Sturdy and well-designed. The groove on the back for cables is most welcome.
    * Big enough to hold their own against mightier front speakers, but not so big that they dominate the room.
    * Very clean and accurate. They match brilliantly with my VAF Research DC-X front speakers, which are also very accurate.
    * Drivers firing outwards at 45 degrees mean they're not dependant on side-wall reflections. Also puts you more "on-axis" for critical listening.
    * Equal drivers facing front and back. Infinity haven't skimped on their woofers and tweeters..
    * Full-range. They go down to a claimed 50Hz and 40kHz. I roll mine off at 100Hz, but it's nice to have the option. For SACDs, they're equal to the task.
    * Dipole / Bipole / Monopole switchable. LOVE this. You can easily tailor them for your room, tastes and placement.
    * THIS is the clincher - Dual-Monopole mode !!! If you already have a 7.1 amp or receiver, you can simply connect another cable for the rear-firing drivers, then switch to Dolby IIx to run everything in 7.1, giving you stereo Back surrounds - four channels from two speakers! This gives you a complex, diffuse surround field while not introducing the bass-cancellation that most dipoles give. In my case, I actually got better results doing this than having a separate pair of Back speakers mounted on the rear wall! Brilliant!! I'm not aware of another speaker that offers this way of operating.
    * Great value for money when you consider all these things.

    I can recommend these speakers with my hand on my heart !

    Infinity BETA ES250

    I am somewhat at a loss at what these are supposed to do. Are they meant to be rear surround speakers or a rear center channel speaker? Do I need just one or do I need 2? I run a 6.1 receiver and I have almost no idea as to the best way to use these if I do decide to purchase them!! HELP!!!!Read More »
