Question: What is the frequency respond of this speaker?
Document: This speaker has fairly flat response over its frequency range with 90 dB sensitivity. It is small sized, so I was able to instaLL it in an upper corner between ceiling and adjacent walls of my living room. Unfortunately, it is not available any more as P162, but it is available as 163BK from Infinity Primus.
Recently replaced my 20 year old Yamaha Receiver-Amp, and Baby Advent II speakers, for a new Harman Kardon 3490 amp and the Primus P164BK speakers. I am pleased with the results.The speakers produce a clean mid-range with sweet highs; however, as expected, Low frequency response is what you would expect from a 6.5 inch bookshelf speaker. I find the bass reproduction subdued and a little "muddy".
These speakers sound great for their price range. They are not high end speakers but then again they don't cost what high end speakers do. I use these for the front speakers of my 7.1 surround sound setup. They do quite well. They are not overly tinny with highs and do have good frequency response overall. I would use them for general purpose stereo speakers as well, as long as the application didn't require a lot of volume in a large room. Other than that, I highly recommend them.
The P163 surprisingly does not need a subwoofer for orchestral music despite it's lower frequency limit of 49Hz.My near-field and typical listening is done at slightly more than 1 meter from the speakers at ear level with a c weighted SPL no higher than 67db (far under 1 watt of input power) and the P163 is was absolutely delightful. Uncompressed and open, the P163 easily handled the second movement of Brahms Symphony 3 (Houston Symphony - Stokowski 2014).
i did not know what i was missing in speakers and true sounds these are a super good speaker just sorry to see they are made in china instead of america since its a american company
Great sound for the size. Using them with a Yamaha reciever. Worth the money.The speaker connections are of poor quality. Use caution when tighting the binding posts.
I never thought of such an inexpensive speaker can play such a wonderful music. The sound is very solid, and reflects that this is a well-designed speaker. The treble is clear, the mid-range is precise and the bass is solid. All in all, this is a well-balanced speaker.
I don't have this speaker, but I've got other Infinity speakers in my home theater and had the legendary RSM's for years. Infinity speakers are ACES! For the money and the high marks users have given these, it would be "worth a shot" to give these a try.
The treble signals are better dispersed with the Infinitys standing on end than the Monitors, whose treble response did not disperse as close to the speaker as the Infinitys did and seemed to produce hot spots, which the Infinity did not produce. The Infinity's midrange is bright - not muddled or colored.
This speaker has an amazing sound. I used two of them to replace Energy Take One Classic speakers and these are much better speakers. I wish I had gone with Infinity speakers in the first place. I paid $49 each so it was a good value for the price I paid.
