Even with an 80Hz crossover, you will sense the greater impact. This woofer hits hard - there is more punch and bass extends lower than much larger woofers. ![]() The Excel motor systems are known for having extremely low inductance (this woofer has less than half the inductance of the standard S2 woofer, which is already low), and this combined with a lower mass cone and more powerful magnet system provides exceptionally deep bass and much improved transients and dynamics. This woofer brings a few things to the table. To put this woofer’s impressiveness in perspective, to produce this woofer, it costs 2.5 times more than the already phenomenal 6” Curv woofer used in the current Sierra 2 woofer. This new Ex woofer, made by Seas once again, is the best woofer Dave has ever seen/used in his 30 years of working in this industry. Well let me tell you, once these are released, you will not stop talking about them. There hasn’t even been talk of them like the Sierra Luna Duo. I know some of you will think, huh? There’s no Sierra 2Ex on their website. I wish I could say more, but I spent the least amount of time with these. Proper, balanced sound, from a well designed speaker. I did not find the Raal to be laid back or the speaker warm sounding, just neutral. Like I said, they made me think it was a pair of 6.5” woofers up there. The bass was very exact, never lingering longer than it needed to be, but was well extended for a pair of 4.5” woofers. I was really impressed with how the Duo did. It’s nothing special up front, but in listening you can really appreciate the differences between a heavier dome and a lightweight ribbon. These things punched like a 6’5” football player, but looked like a 5’10” tennis player! I must say, I’m a pretty big fan of the Raal tweeter. Listening, I came up with a word to describe them. My eyes kept picturing a ginormous stand mount speaker using 6.5” woofers, but I would realize that the sound was coming from this tiny little speaker. Throughout my listening, I really could not ignore the fact they sounded like my own CMT340’s. Now these were the first speakers I heard, they were setup when I first came in. Dual front slot ported, tuned to 60hz or so. It’s an MTM using dual 4.5” Curv woofers from Seas and a Raal 64-10. Artists include Miles Davis, Daft Punk, The Eagles, Red Hot Chili Peppers, Gorillaz, Bob Marley, and some others. I had a listen to a pretty large range of music, all of which were FLACs found in their music server. I heard the Sierra Luna Duo’s, Sierra 2Ex’s and then A/B’ed the Sierra Towers w/ Raal with the Sierra 2Ex’s. ![]() I plan on returning in the near future for special reasons, in which I will correct these issues. To say my hearing was and is far from perfect would be an understatement. I also had just came from a 8 hour car ride that consisted of many elevation changes, one of which was the Grapevine in which I went from sea level to 5000 ft back to sea level in about 90 miles. Well here’s a recap of my visit two weeks ago of Ascend Acoustics HQ, located in San Clemente, CA.ĭisclaimer: To start off, my ears are not anywhere near audiophile quality. ![]()
