Finally.....i decide to go with the Seirra Towers With RAAL & Seirra Horizon With RAAL both in high gloss Satin dark cherry.
But i am confused in the bookshelf's!!!!! There is three types : Seirra 1, CBM-170 ES and HTM-200 SE.all the three in same specs.
Which the preferable one of them ? I need the better one of them, And could to buy it with RAAl Tweeters also ?
It depends on your needs...all three have different capabilities.
If you just needs to surrounds for HT duty, and want something easier to mount, the HTM-200, which are sealed, do a fine job. Iuse these as surrounds...I have Sierra-1's as my mains/center.
For more capability, deeper extension and high output, the CBM-170 is the choice, but mounting is not as easy since it is rear ported and a fair amount larger than the 170's.
The Sierra-1 is also rear ported, but the best match for bookshelf styled speaker to the Towers in Ascend's standard lineup. Ascend can also customize this (at a premium cost) and use the same RAAL tweeter as you are getting in the Tower/Horizon, if you desire.
