## Description

Product Description

Review: Sonido exelente. - Buen producto, bonito y con gran calidad de sonido.
Review: Great set of Passive Speakers. - Great set of speakers. Have them set up in a living/dining room area and they fill up the room beautifully. I run a 300w mini amp which is more than enough to power these. The bass is very clear which is desirable. The vocals sound very good especially female vocals. Listened to Nick Drakes "Pink Moon" and I heard and felt things I've never experienced after years of listening through bluetooth speakers and sub bass tuned headphones. For the price an absolutely stellar purchase. Banana plugs will fit perfectly and they look elegant. Thought I would like the look of the grill removed but after consideration I left them on. The may impede the sound but if you don't have an ear for it you will not notice it unless somone tells you.

### ⭐⭐⭐⭐⭐ Very Impressive High Value Speakers
*by C***E on 28 October 2024*

1. I measured these and the frequency response is pretty linear...they did a nice job with the crossover. 2. The grills are very attractive but are not magnetic 3. The binding posts are substantial...like something you would expect on a much more expensive speaker. 4. Build quality is good for this price. They are fairly heavy and solid for their size...this is where they really exceed the other speaker in the picture...which appears to share the same driver and tweeter. 5. In my room they got down to 50hz with pretty good output. Below 50hz they roll off quickly. 6. Sound signature is good clarity but also relaxed and balanced sounding. These aren't in your face sounding like Klipsch, but they won't put you to sleep. 7. They have more output than expected, given their size. 8. One minor complaint...the feet don't appear to be removable. 9. I like them a lot more than the Sony SSCS5 speakers (harsh with too much sizzle) & ELAC BS41 (not enough clarity & sloppy bass). 10. Make sure your amp has a 4 ohm rating. I tried these with a less capable amp and they still got loud, but the fullness of the sound suffered. 11. The RSL IA255.1 amp is a great match in the affordable amp category.
