Good lower bass output, good imaging, good tonal characteristics. Entra series while lacking to the Alphas, was slightly better than the Polk R series which had sonics I preferred less than Infinity.

Upper bass emphasis can create a boomy sound. Priced high when considered to the previous RS line. Midrange could be more refined. Entra series debutted with Interlude series, which directly replaced the RS series.

These speakers are nice but a bit overpriced for their lower quality when compared to yesteryears RS series. The RS series was replaced directly by the Interlude series. The Interlude series also boosted their prices to high. Their performance was similar to the RS series, which was less expensive. The Alpha series was a direct replacement for the Interlude series, which bought prices back to a normal level. Prices are similar to the pricing of the previous RS series. The Entra series and the Alpha series share similar voicing "BUT" there is a definate difference although the same drivers are used. The difference is large. The midrange is masked and muddy compared to the Alpha series. The bass is also over emphasised in the high bass making it boomy. The Alpha series lacks this boomy bass. Infinity stated that the Alpha and Interlude series do use similar drivers "BUT" the crossovers and cabinets are much cheaper in the Entra series to make them a more affordable budget speaker. The cabinet and crossover seem to be causing the high bass emphasis and the less precise midrange characteristics. These speakers do sound good but are not a good value for their price. The Alpha 20 bookshelf speakers have the same size drivers but with better crossover, cabinet bracing and tuning, sounds 'MUCH' better and very similar to the much more costly Alpha 40 with less bass output. For the same money, I'd buy the Alpha 20's. The Polk R series has the same sonic differences compared to their upper line RT series, as the Entra series compared to the Alpha series. Surprisingly, the Entra series has a R series twin and the Alpha series has a RT series twin except that the Alpha 50 use two passive 8" woofers and the RTi100 uses one built in 6 1/2" 'powered' subwoofer. The Alpha 50 sounded like it went deeper however. Alpha series seemed to image better but different room placements could cause that. I didn't situate the speakers in the same position since sonically, the Alpha series sounded much better without considering imaging.

nice looking, very clean undistorted sound, able to handle high volume. I guess its my fault for expecting big sound from a small 2way speaker

lacking bass and when compared with other speakers, seems to be lacking a lot of midrange too.

Looking for main speakers a year ago and compared these at circuit city. I was apprehensive because of small size and driver, but they sounded very clean and detailed compared to speakers in the same price category. Over the past year I have come to realize that the highs are outstanding, the low frequencies are clean, but there seems to be a lack of midrange in addition to the lack of thump. I have a 12" powered sub which provides deep bass but I still feel that the infinitys don't provide the supplemental bass loud enough. My friend has a pair of old 3 way kenwood speakers with 8" woofers and they have so much more bass than my fancy infinitys

High-frequency DETAIL-almost to a fault, but this is why I bought them. Excellent midrange.

Slightly cheap-looking wood grain cabinet construction, flimsy grille. Weak Bass.

My first floor standing speakers. They were an improvement over the RS2 bookshelf speakers I had been using, but being 2-ways with 6 1/2" drivers they can only go so deep. As with all Infinity speakers using their CMMD driver material, they are a bit on the bright and analytically-detailed side. Moved them to the surround channels when I purchased a pair of IL40's.
