Helos Better than expected
I bought 5 of the Helo 20s online for a pretty good price, I have used another top of the line brand for the speakers in my other room but after installing these for the first time I was very impressed and surprised at how crisp and clean the sound was from them as well as the much better improvement from the speakers that I have in the other room.. thanks a lot

Very nice sound quality with good bass with moderate price
Initially I plan to buy bose 191 speakers but I saw Helos 20 has 80% of the price on amazon on X'mas day so i rush to local magnolia center of Bestbuy to listen the sound quality but i was unlucky b'cos they don't have setup for helos 20, so i was little upset and was confused too b'cos i dont know what to do but suddenly what happen to me that i placed order on amazon for 10 In-ceiling Helos 20 speaker. After placing order went to martinlogan website to check for authorized dealer and found fry's so rush to their place and listen the sound quality which was way better than bose and better bass compare to bose 191 in-ceiling speaker. I took an deep breath thinking that all my investment and decision is worth selecting helos 20. On Jan 6 2010, all of my speakers and onkyo HT-RC180 arrived and it took me one week to put 6 speaker into ceiling and guest what on friday night after everything was ready and configured with onkyo receiver, I just turn on the FM and boom......great sound quality and enjoy blu-ray movies with THX, Dolby, etc sound with my onkyo receiver. Now i'm adding two more helos 20 speaker for sourrond back left/right and also planning to buy center channel and sub-woofer speaker from Marting logan itself. Finally, I would definitely recommend to buy this speaker but before that listen and decide because everybody has their own view and ear too. All the best for your shopping.....!!!!
