    Default Is Sierra 2 enough for my room or stay with current cmt340?

    Hi everyone,

    I have cmt340se lcr with 18” subwoofer in my family room that is 32x18x8 which works out to 4600 ft3. I want to upgrade to Sierra 2 but am concerned they may not play loud enough? The room is open to other parts of the house on two sides as well. We sit 12’ away and the L/R speakers are 12’ apart.

    Here’s a short video showing my room setup with my wife trying to duck out of the way. Lol.

    I’m heading to ascend Friday to listen to the cmt340 and Sierra 2 back to back just to ensure the upgrade would be noticeable. Reason I’m sure it will be, is because in my dedicated music room I have Raal towers and horizon Raal and they are incredible. More towers won’t work with my room as you can see. Bookshelf/monitor is all that will work.

    I listen to pretty much 100% music. Lots of edm, indie rock and roll, classic rock, oldies, and some
    Pop. HT doesn’t work with a 5 yo and 19 month old. Ha. Plus I love music way more.

    Any input appreciated. I have an email into Dave about it, but figured I’d put it out in public to help any others that may have the same question, and maybe Dave will just answer here.

    Since your going to Ascend to listen, that is where you will make the best decision.

    What I will advise is to move your 340's out of the corners, also get them to front edge of the counter for the best sound.

    I know the Sierra 2’s are going to sound better than the 340’s at ascend but I don’t know how much better in my room or at volume in my room.

    I can move them away from the walls but then my listening distance will be farther than they are apart (not equilateral triangle anymore).

    Only way to know is to trial them in your room.

    If you think they are worth the upgrade cost at Ascend, bring a set home and give them a try.

    That is just a guideline, not a hard rule.

    On top of that, you want to move them forward on the table so there isn't a reflection point caused the table/ledge in front of the speaker.

    I think this is the play and what I will do, just trying to avoid the hassle if someone has used the S2's in a big room and had feedback regarding that.

    I will move them forward. Thanks for that. I will also try to move them away from the wall, but the wife won't like a hole being in the countertop where the wire comes through, LOL. Last question, is there a recommended distance they should be away from the wall? Thanks.

    Love that cabinet with quad SI 18s... If your planning on going to Ascend why reserve that visit solely for the S2. I'd give the NrT S1 a whirl too. A wee bit more dynamic or sparkle perhaps since its for HT( rather music....cest la vie...lol)....because you got the low end covered.

    Ah, I see. I sit about 11-12’ from my S2’s and they are plenty loud for me. My first level is all open and about 11.5-12,000 ft^3. It’s pretty loud about everywhere in the house. Lol

    I’m not sure how they compare to the towers though as I’ve never heard those. I did just get a Horizon w/RAAL that is awesome.

    On another note, how about using horizons for mains? Looks like you could use them horizontally or vertically on your shelf.

    I’m jealous of your music room. Looks awesome! I can’t even fathom what 4-18’s sounds/feels like.

    The Sierra-2 will have better detail and clarity but the 340 has 5db higher sensitivity. So you just need more amplifier power to reach the same output levels with the Sierra-2. Also the driver arrangement (MTM vs MT) may have some difference in the sound. Almost forgot, the maximum output capability for the 340 is higher than the Sierra-2, so that's something to consider if you like to play things really loud. For my listening, the Sierra-2 is plenty loud.

    Appreciate your insight. I talked to Dave and he agrees to just test them at my house and see what happens. That's what I'm going to do, and I'm sure it will turn out great.
