Ascend Acoustics Sierra 2 Bookshelf Speakers: ⭐️⭐️⭐️⭐️

Sierra 2 Speakers are top of the line bookshelf speakers from internet direct sales speaker manufacturer Ascend Acoustics inc, which retail at $1448 + $36 for shipping within U.S. I had Sierra NrT tower speakers in my system a while back but I sold them to replaced with KEF LS50, it was good speakers in my distance memory.

Build quality of Sierra 2 speakers is excellent, however SVS Ultra & KEF LS50 speaker cabinets are more solid in comparison.

Out of the box sounded some what thin at the place of my KEF R300 speakers, but improved after adjusting the placement with some toe in to get best possible stereo image at my listening couch, After a few adjustments I let them break in for 5 days straight streaming Pandora 24 hour non stop in second system.

On sixth day, I made a few more adjustments, which I settled at about 25* toe-in, 7ft apart before I sit down and listen to my music selection by playing Heavy Metal, Jazz, Soul, Pop and many different genre of music. Overall sound is very good, highly praised RAAL tweeters sounds very clean and transparent with every detail can possibly hear by human ears, which I really appreciate details and transparency of Sierra 2.

Instrument placement was easy and effortless, 6” driver from SEAS is pushing out impressive clean bass notes but as I’m getting more playing time with them I would like a little more body in high frequencies but some may find it suitable to their taste, also a little lack of warmth in high frequencies range although it never sounded bright in anyway but I need more body and warmth in upper frequencies, high piano notes are accurate but left hand keys notes from piano were a little unnatural, missing the striking impact of weighted keys in each notes like I used to with KEF LS50 speakers, it just a tad soft.

Also drum strikes are not dynamic enough for mex otherwise very good speakers and I realized this Sierra 2 speakers are not going to be great all around speakers for my taste of music, as everyone knows it is hard to find a speaker with clarity and neutrality with good balanced sound.

Male vocal performance was very good but female vocal is a little less accurate as I’m used to with LS50, which is closest to reproducing Diana Krall voice to what I’ve heard in her concert.

I did not like Sierra 2 with 80s, Hard Rock, Heavy Metal or Orchestra music, the problem for me was very detail sound but missing realistic musical impact, dynamism of music emotion that connect to the artist creation, well extended non fatiguing highs but lack of weight and neutrality to me but these speakers really do excel with Jazz, Pop and slower music.

In my opinion Sierra 2 are fine sounding speakers with a little bit on lean side but it doesn’t mean that lack of bass response, it’s plenty of bass, a little bit better bass response than LS50s in my system but I much prefer LS50 balanced sound overall for my music because I felt that Sierra 2 high frequencies are slightly disconnected from lower frequency of music and vocal, natural, spacious, lively dynamic sound is very important in my everyday music.

Also, low level music listening late at night playing smooth jazz is not so smooth due to disappearance of lower frequencies, a lot of speakers failed this task but not at this price, it may not be important for everyone but very important for me because I do listen to music in my bed room at night.

For someone who must have RAAL ribbon tweeters:
Also there are offering like Philharmonitor with same RAAL ribbons from Philharmonic Audio which will be very much comparable to Sierra 2 yet much cheaper option to have.

Pros: Quality Components, Clarity & Transparency.
Cons: High Price, Sound Stage.

Mid-Range: ⭐️⭐️⭐️⭐️½
Bass: ⭐️⭐️⭐️⭐️½
Sound Stage:⭐️⭐️⭐️½

I made this video for the people who can’t audition the speakers or the equipments.

Note: This video is posted straight out of the camera and recorder. No video or audio post processing other than adding titles.

This video/Audio will not sound 100% accurate as auditioning in the real world, however I would recommend using good monitor headphones and play in HD to get best sound quality for your reference. (My reference headphones are Sony MDR7506 & Audio-Technica ATH-M50)

wow, I love the highs of them, sweet and expressive. ‘-‘

Oscar Sanchez Jr, BSc. says:

Please play Napalm Death’s “Plague Rages” so we can hear if these speakers can really handle a complex musical signal. 😉

Paul Horn says:

So, which do you prefer these or the Wharfedale 225’s?

Liba Barefro says:

2:10 is that the freqency response for these speakers ?

GertJan van der Kooij says:

great little speakers,even better than kef ls50

SinSillas Nano Reef says:

Wow, the sound of the Raal tweeter is truely something special. If only there was a little more punch and bass definition (id liked the ls50 over the R300 bass) id be all over this speaker. But could be a killer combo with a Rythmik subwoofer. In your review you say that bass response is better than LS50, but comparing your Sierra Videos with the LS50 videos (especially Rock and House) the LS50 clearly has a punchier kickbass than the Sierras. How come? Do you plan to review LS50 Wireless? (Listening on AKG Q701)

zenjoks says:

Less air between instruments and overal in 3d compared too LS50…

Eric says:

I sold Mine and got the RAAL towers. That filled in all the missing links for me. I have been curious about the LS50 for a while now.

Baptiste says:

You do nice comparing work ! All budgets and all kind of speakers, continue like that !

achn2b says:

Thought they sounded pretty nice with the Yao Si Ting, but listening to this, it sounds like there’s a little heft or weight to the music missing. The details and information are there, but the fullness or body of the performance is light.

worstalentscout says:

despite the poor mike……….sound is very coherent and smooth……..vocals also very convincing….

Arthur Watts says:

Uploader, I get that you’ve put a lot of effort into this but (in true audiophile fashion) our respective understanding of what constitutes a ‘rock’ track seems to be about at least a kilometer apart. I accept that the rest of the world doesnt share my passion for harder rock / metal, and I thank you for not trotting out the usual Eagles / Steely Dan medley, but there IS a middle ground and its glorious.

Anyone who might consider that a bit too laidback need only skip to the 4.30 mark and they’ll be treated to a solo as good as anything Vai, Satriani or Van Halen ever laid down (IMO). I know its not lossless, but them’s the breaks with YT. Thanks for your time – enjoy your speakers.

neonRTowner says:

Those ribbon tweeters are crystal clear. You can hear the pace and rhythm of the set up. No boomy cabinets, no wimpy midrange – some of the better YOUtube stuff of recent memory. Well done.

59seank says:

I liked the sound of the Kefs better.

Gary M says:

Too much bass compared to every other speaker with this song. Not boomy but it overwhelms the midrange. The drums at the end sound like drums on the Wharfedale 225, on these Ascend it sounds like a tweeter. To be fair, I know I’m not getting the full effect of the RAAL through my speakers.

John Adams says:

I do not hear any base frequencies at all.

kamaboko1 says:

I have a pair of the Sierra-1’s and they sound great. The funny thing about listening to audio demo’s on YouTube ( or any other channel ) is that they don’t even come close to the actual experience. For instance, to suggest that my Sierra’s sound the same over my MacBook Pro speakers would be absurd. The only way to truly experience a speaker is to be there in person. It’s like trying to experience the thrill of a rollercoaster ride watching a video. Ain’t gonna be the same.

Alpaslan Bek says:

The best in all the bookselves that has been demoed by the channel owner.. (listened with a ATH-M50)

Rain Roosild says:

This speakers are dead 🙁 Sound is good but lifeless. No one will even hold two books Evie Sands face side like doing JBL Studio 530’s.

Mike E says:

I went back and forth between the r300 and the sierra 2(same songs) and the highs sound clearer/more define on the sierras. I’m listening on my calibrated flat computer audioengine speakers.
