Summary: OK, speaker it works the added features are more gimmick than useful in my opinion as an ex-trucker. The size of the speaker is very nice though so, I may just gut the speaker and hook directly to the speaker and remove everything else, but that is just me, you, may like all the whistles and bells.
Summary: Surprised in a good way by the quality of this speaker. Well made. Good size. Handsome addition to my radio shack. Color is a close match for my Kenwood 940SAT. Don't use the "noise reduction" switch, but maybe it is useful for mobile operations. I would recommend to others.
Summary: Also have speaker only version of HG S500. Was excellent in car..good loud clear understandable voice speaker. Same, but using both in house now, with same great results. Do not recommend for quality music. / I have HR2510 CB radio that I need to hear myself with.
Summary: Not amplified (which I knew), and not much filtering (there is an on/off switch on the back for the filter mode, can't tell that it helps much), but overall has a nice, clear, rich sound. Not tinny or cheap sounding. Appears to be solid and well made.
Summary: Not what I expected it looks nothing like the pic I bought it to hook my scanner up at the race track and I was very disappointed I couldn't hear anything and I have to know when to go out for the sprint cars very disappointed
Summary: I have this for one of my 4 scanners and I have been using uniden speakers, but this one is better, although its the new design not as shown here, its a great durable speaker very satisfied but I wanted the black one shown but this is so good im keeping it.
Summary: after reading the great reviews i ordered one..had it for a month or so now and i can say,it works..nothing speacial at all but works..the speaker is ok but not as good as my 2995dx stock speaker is..the talk back sucks.
Summary: This speaker works very well for a CB or Ham radio and the audio quality is much better than the normal speaker on the radio. It allows conversations to be easily be heard in the mobile environment where there is a lot of outside noise. The speaker is very loud if turned up as well.
