Going about comparing floorstanders directly by specs might not exactly be a right approach. As most of FM's suggest the best way to know is to audition them , as most of our opinions would be subjective in nature and to add your preferences/requirements might not exactly match someone elses
I am going to write a big story to give you an idea on how I perceived the different setups below, so feel free to skip to last paragraph on the Achals if it gets boring anytime
I have previously owned QAcoustics (Concept 20 & 3020i), Dynaudio Emit M20 , ELAC FS 57.2 & XTZ Spirit 11. All of them were great bookshelfs to start with
- Concept 20 sounded very refined and had very good amount of details with clear mids , decent soundstage for the price being paid , lacked bass quantity but whatever present was tight and precise.
- 3020i sounded ok as I was used to the Concept 20, was less refined than the Concept 20 and had a similar soundstage with slihgtly laidback mids. I was using it as surrounds mainly and worked great for that purpose. Lacked bass quantity
- Dynaudio Emit M20 - Super sweet mids, amazing hard hitting and deep lows. Treble for me lacked the sparkle which I had chanced upon in the floorstanders i had auditioned. Was the hardest to let go from my setup
- ELAC FS 57.2 - Was delivering good value for the price I paid, had nice hard hitting bass, decent mids and treble details. Soundstage was ok for a floorstander. Was every bit worth the purchase as this got me invested into Floorstanders.
I decided to go audition further for Floorstanders and will describe brandwise
QAcoustics (3050i) - Was pleasantly surprised with this , certainly packs a punch and is decent sounding. Presented a nice large stage during auditions. The bass quantity was a lot even in the treated room , but was not very interfering into the mids. Have seen some FMs mentioning its little difficult to tame in smaller room sizes
XTZ (Spirit 11 & 95.44) - Spirit 11 is very neutral , is true to the source and presents music almost as is. I liked it during the auditioning sessions
- 95.44 was much more energetic and might I say a little bright in its presentation. Sounded good during the audition but did not go for it as i had a thought it might end up being fatiguing for longer sessions.
KEF (Q950/Q750/R3) - R3 was my favorite amongst the lot despite being a bookshelf. Had everything I was looking for but did not want a bookshelf , Q950 also had amazing imaging (probably the best amongst ones i have listened to till now),very deep bass, vocals were forward and treble was on the aggresive side, out of the lineup enjoyed the auditions of the KEF lineup the most.
Klipsch (The entire FS lineup) - Had great amount of enegry and deep bass. Those were the only 2 positives for me, otherwise was ear piercing in terms of the treble, mids were not enjoyable and did not like them. This was the last place i went to , so could have been fatigue creeping in too. But considering thats how most of my working days are with some form of fatigue creepign in , made no sense to try it again.
Focal (Chorus 726 and Aria 926) - The Chorus 726 sounded very bad when i tried it in a showroom. Had good bass , but treble and mids were totally out of place. Sultans of Swing was made to sound harsh, probably because of the configuration and an old AVR being used ot run them. But that totally put me off and i thought no more Focal as 926 is not available for demo in any showroom. Luckily a FM invited me to audition the Aria 926 and i was blown away by the top end of the focals, the highs were mind blowingly amazing with good soundstage, mids were little laidback but still sweet enough and lows were not present, understably so as the OP had a very huge living room.
I got the Focal Aria 926 as my main front setup and Spirit 11 as the alternate complementing setup at the rear side. Eventually i felt the Spirit 11 to be too neutral and treble was little thin sounding to my liking , but dont in count these out from your auditioning list as they are one of the best sub 1L speakers you can get. Once I decided to move away from the Spirit 11 , I auditioned the Achal (something which I missed during my first auditions) and they sounded balanced in a good way in below aspects
i) They had the 2nd best lows from the speaker lot i auditioned (best being the KEF Q950 which would come to about 1.35L-1.4L post discount)
ii) They had very good mids , on par with every other speaker I listened to. Focals were more intimate but sound like a row behind in presentation and with the Achal intimacy is a little low but they make up by being at the exact spot i would like the vocals to be present at.
iii) Treble - Had a good amount of details with really good instrument seperation, had a decent depth to the soundstage too. The Focals here for me were clearly much better, but Achal was 2nd best amongst the entire above lot (barring the KEF R3 obviously).
The best part is all of the aspects combine really well to form a overall musical yet detailed signature. I just got my Platinum Achal over the last weekend, have been burning them in and had a good session of 3-4 hours of listening today. Can say that I am happy to have gone for these after giving away the XTZ Spirit 11.
