    I have had a love/hate relationship with Infinity Loudspeakers over the years. As a former Interlude, Alpha, and Primus owner, the exaggerated mid-bass and somewhat flabby low end have been their fatal flaws. Why do I keep coming back? Simple: value. IMHO, the higher end Interlude series didn't justify their price, and the Entra 3 offers the majority of the performance for a fraction of the cost. The Entra 3 also doesn't have the famous muted top end of the Interlude series, but still retains the smooth characteristics Infinity is known for. Big, warm, and somewhat sloppy at times, the Entra 3 is a fun Loudspeaker for those that don't take their audio too seriously.

    Clear and well defined.


    Bass is a little boomy but not bad overall.

    Bought these on sale to replace some 13 year old bose 10.2 Series II speakes which now provide surround sound. I didn't have a lot of money to work with, so I knew that expensive audiophile speakers were out of the question. After bringing them home and hooking them up, I was a little apprehensive because my center seemed to sound better and louder ever after adjusting them. Before panic set in, I decided to let them break in for 2-3 weeks and then check them again because I heard that speakers have a break in period. Well, after 1 week I noticed that the sound was smoother and more laid back and blended in well with the center so I kept them. After 3 months, they blended seemlessly with the center and the sound is fine. The highs are well defined and not to bright and the mids/vocals are clear. The bass is a little boomy but not bad overall. They fill my whole house with sound not just the living room. They have 5 way binding posts which I just adore. I never did like those spring loaded clips. The frequency range is 40-20,000 Hz. Looks like they built them from 3/8" or 1/2" MDF and then covered them with a wood tone vinyl or laminate. Overall, the looks are good. The size is not to big or to small. Overall, I have to say that for less than $400, I am very pleased with these speakers.
