Question: Has anyone heard a comparison between these and the Sony SSB1000? Any thoughts?
Document: I have these hooked up to a yamaha 473 and they sound very good, well worth the price. I would reccomend these to anyone
I had already replaced my old speakers with a local product which, although having all the requisite specs, gave a disappointing performance. These are worlds apart. I would recommend them to anyone. (Anyone who has a suitable hi-fi system, that is. )Many thanks.Paul H.
Hello!I am writing this review in hopes of helping anyone out there.To start, I have used some Pioneer products for years and am a fan.Having said that, the quality I found in other Pioneer products was absent in these speakers.They look good, they seem well built and to look at the spec sheet, one would think these speakers are a decent deal.
I don't find myself having to tamper with the DSP features in my VSX-1021-K when switching between formats at all. Matter of fact, I've since disabled all DSP on my receiver and now just listen to everything as it was originally intended without fear that I'm missing out on any details.In short, my wife and I are very satisfied with the BS-21s and would highly recommend them to anyone. Period.
So mounting them as a surround setup is tricky. They are too heavy for many of the common mounts meant for the typically sized sattelite mounts. I chose to build my own shelves. I also saw a "speaker mount clamp" product on Amazon by VideoSecu which might have worked, but I went with the shelves.I would recommend these puppies to anyone who would want to listen to music on them.
Keep in mind that these speakers are not as sensitive as most, so they will require a little extra volume before they show their true potential. Once you do, however, they really do shine. Midbass is very accurate and the bass is never overwhelming. All I've heard so far is a very clean, warm sound.
I realize that I need my ears to acclimatize to the new sound but I have to say, my old $200 Sony speakers/receiver combo from walmart sounds better to me so far. I have mostly listened to them at low/mid volume (20'x20' room). Maybe some sort of break-in period needed?UPDATE. The commenter below is right, 2 stars was a bit over dramatic. I change to 3 stars.
very good speakers for the money, can't go wrong with these I use them for my surround sound and they make a good addition to my other speakers
order came quick and was very pleased with the sound from these speakers!!! i going to buy more speakers for my 7.1 hookup very soon
love the sound.
Answer: Sorry, but as Gary P says, "middle of the road units". Still, if you´re in the middle of the road, why not travel cheaply and well. I´m delighted with mine. Paul H.
