Summary: I purchased these speakers to replace a set of Infinity Reference Two bookshelf speakers that were still fine after 18 years of use. I am still breaking them in, so they probably don't yet produce the full accuracy and range of sound they are capable of, but they already sound amazing in my office, just sitting on a carpeted floor, and even better sitting on top of a wood credenza.
Summary: Having owned the entry-level Primus 152's for a year and impressed with their good sound I wanted to take advantage of the lower internet pricing offered on the Beta 20's and then give them a user review. Infinity has and still uses their C.M.M.D. (Ceramic Metal Matrix Diaphragm) drivers on some higher-end lines on current models and those that preceded the Betas and the company implies that its properties have sonic advantages over other materials when compared to...
Summary: I was lucky enough to pick up a pair of these for the price of one, and with my system setup works very well as the front speakers in a 5.1 setup! For the average consumer, this speaker will do fine in a decent size, large living room/family room set-up with a good receiver. I have MANY friends who use Infinity as their preferred brand (including my stepdad) and when you hear these babies with a good setup, You will see why!!
Summary: This speaker really is the best bookshelf out there in its price range. It has extremely good response for base, midrange and highs. Despite what some have said with a 80hz crossover and paired with a decent subwoofer these speakers handle music extremely well. They are accurate and give a nice flat response on a good receiver. I have used these on an old Panasonic HE100 and a new Onkyo 705.
Summary: They have a great price! They will blow away any other speaker in this price range. If you want to upgrade your system or start a new one and are on a budget look no further than the Infinity Beta 20.
Summary: The Infinity Beta 20 are perhaps the very best bookshelf speaker in the sub-$1000 category, they compare favorably with models offered from B&W, Paradigm, PSB, NHT, Wharfedale, Monitor Audio, and Mission, and the fact that they routinely sell for less than $200/pair makes them the singular best bargain in Hi-Fi today. I've owned mine for several years now, and absolutely love them. The reviewer who stated that they have poor mid-range could not be more wrong, IMHO.
Summary: I have owned a pair of Infinity Beta 20 for 4 years, and I am not a happy owner, not at all. First, the good ones - their high frequency reproduction is pretty good, and they do have little resonance. Now, the ugly, they have very poor mid-range, it is muddy and unclear, at any volume level. This is especially apparent for low pitched vocals. Just how bad does it sound? Well, my $15 Altec Lansing desktop speaker sounds clearer, and I paid $400 for them.
Summary: These Infinity BETA 20's had sounded incredible as part of the sides of my 7.1 Surround System. They were matched up with the Infinity Beta 40's and Alpha 37C Center Channel Speaker for the fronts, sides were the Infinity Beta 20's but now Beta 40's, and the rears the Beta ES250 Surrounds. All are driven by the Onkyo TX-SR805 powerful 130 Watts x 7. I have moved these to my Living Room...Crank up the sound!!! You simply can't go wrong with these excellent CMMD speakers.
Summary: You can always trust amazon.com for your order and at very good price; I ordered these speakers and got them like in less than a week. I connected 12 gauge speaker wire to these. These babies are priced higher just about anywhere on the internet. These rear speakers I have the crossover frequency set @ 60HZ.
Summary: The speakers are amazing as noted in many reviews. I do want to point that they also have the greatest customer service. They answer phone calls right away and emails within 24 hours, and go out of their way to make you happy. Thank you so much Lady B.Wilson. You are an angel. A.
