Yeah. Any speaker can be bright with any tweeter - just turn up the tweeter. It's all relative.

Here, the bookshelves will be close to wall behind them and only 4' apart. I'll be 2' from each. Sub can go in at most 3 locations: to left of desk, below desk next to my feet, and to right of desk. I'm concerned about bass management. As you noted its easy just 80 and 120 settings. more concerned about gain tweaking, position tweaking and integrating. Have listened to many badly integrated subs at my friend's apartments and at every big box store that sells subs. Clutter is also a concern in small room.

As others have indicated, I think you're going to want a receiver (or other method) to apply either Audyssey XT32 or Dirac. I don't think it's coincidental that the most commonly recommended ones around here often come with one or the other (or something like a miniDSP that will let you do the same thing without the receiver).


I have owned several Onkyo's, back when Onkyo came with Audyssey, but pre-XT32 (or I didn't buy high enough up on the food chain). The HDMI board went bad on the first one. I still use it via Optical In in my bedroom, but it forced me to upgrade/rebuy much earlier than I planned. The other has been a real tank in terms of a big clean power bank (NR809; 135 wpc into 2 channel) that has run well and driven hard for almost a decade now. But "XT" falls far short of "XT32" for bass management, and that NR809 only came with "XT". My main room now has a Denon x4400h, and XT32 has made a significant improvement for my base management, and I definitely recommend it or some other similar solution.


Some subs, like Rythmik I use in my main room, also have extra knobs that can be turned. Most of those knobs are disabled when applying bass management at an AVR, and particularly if using "LFE In" input, but per their guidance docs if you use "Line In" instead they'll support a 24 dB/octave slope roll off, rather tha 12 db/octave via LFE In, which I've been led to believe is not particularly common...


I stayed "on a safe and well traveled path" with this last round of upgrades. Denon Receiver (with XT32), Ascend Sierra's with RAAL Ribbon, and Rythmik sub, was a recommendation I saw on here over and over again for years before I bought... and FWIW, it's been a significant improvement over the gear it replaced. TIFWIW.

Sierra-1 vs Sierra-2EX

If the Sierra-2EX is a 10, what is the Sierra-1 on a scale of 1-10?

Thanks...Alan

Hi again, Ascend thread.

I currently run Sierra 2's for my L/R/C in my home theater setup. Has anyone upgraded their 2's to the 2 EX's? If so, what were your impressions? I'm toying around with the upgrade but am not quite sure it'll be worth ~$1100 over my 2's.

Edit: just typing that out makes me realize it's probably not worth it for the price/performance ratio, but nevertheless, opinions welcome.

Be wary of the upgrade kits. My experience trying to upgrade from the Sierra 1 to the 2EX was that it was not a drop in replacement (one of the driver holes in the enclosure was a hair too small and would not fit the driver). Apparently the upgrade does not go well for a small percentage of people. I ended up keeping my Sierra 1s for surrounds and bought the 2EX.

Given that, if you are happy with what you have, I'd say stay with it. I doubt that the differences would be significant for HT usage.

i too was going to suggest that $1100 is a big chunk of change to gain a moderate amount of improvement.. it may well be worth it to many though.. my suggestion sell the 2's and order the 2ex...you should get enough from the 2's to come out "ahead"..

If you are upgrading from Sierra-2's to EX's the upgrade will go without a hitch. The issue mentioned happens if you have an early batch of Sierra-1 cabinets from the first few runs when they were released in 2007 or thereabouts. I ran into it when I upgraded to Sierra-2's, where I had to open up the woofer cutouts to make the Sierra-2 woofer fit. When I did the EX upgrade everything was drop-in.

I am very happy with the EX improvements, but mine are for a music only system. For HT I don't know if they will have as big an impact on the sound. They can play louder and have greater dynamics, and are clearer with more detail in the mids.

If you can sell your 2's for more than half the difference of buying new EX's it will be cheaper than the upgrade kits, but I've seen a lot of 2's flood the used market.

As others have mentioned, selling your Sierra 2 and buying the EX is probably economically the best move and even better is you can order the EX and A/B them so you know you're making the right decision without any risk.

Outlaw 2200 Monoblocks with Towers and Horizon Center

I am seriously considering purchasing a pair of Sierra Towers w/Raal and a Horizon center. I already have two Outlaw Audio 2200 monoblocks that power my fronts. I contacted Yamaha about powering the Horizon center (4 ohm) with my Yamaha RX-A2060 and they emphatically told me "No." So, I guess I will purchase an additional Outlaw Monoblock to power the Horizon Center. Just wanted to check with Ascend owners who use Outlaw 2200s to power their LCR and if you have had any issues with this arrangement. I am assuming not, but wanted to double-check before shelling out the $ for another monoblock.

Yamaha Aventage RX-A2060 AVR, 2 X Outlaw Audio Model 2200 Amps (fronts), Klipsch: RP-280F, RP-250F (surrounds), RP-250C, R-14S (F. Presence); SVS SB-3000 SWs X 2, Bluesound Node 2i, Samsung BD-F5900 BP, Roku Ultra, LG OLED 55C6P UHD.

My Ascends are powered by Denon 4300 receiver. My basement is large and have openings on both sides and never had any issue. When listening at loud volume the Infinity fan powers up and that's about it. Doubt if you really need these as Ascends are easy to drive.

From my reading through the Ascend Acoustics website forum on the Towers, I got the general sense that the Towers are easy to drive. Since I already own the Outlaw monoblocks for the fronts, that is a moot point. Yamaha says not to run any center under 6 ohms or the RX-A2060 could shut down. That is why I am concerned....

Our Horizon, like our towers, has a nominal impedance of 8 ohms. Minimum impedance is not nominal impedance. Most 8 ohm nominal speakers will have a minimum impedance between 4-5 ohms, most 4 ohm nominal speakers will have a minimum impedance of 3.2 ohms or lower.

Our Horizon and Towers are an extremely easy load to drive for basically any decent amp or receiver. Your Yamaha can run the towers and horizons 24/7 without issue.

Thank you very much David! Just what I needed and wanted to hear. Guess I was not clear on minimal vs nominal impedance. I will press ahead without worrying about purchasing another monoblock!

Thanks Lp85253. In Yamaha's defense, when I mentioned 4 ohm, they probably took that to mean nominal impedance. Anyway, I am thankful to all of you on this forum and other AVS forums...I have learned a great deal of valuable information!

Be careful with these forums!! Soon after you buy your Ascends and other stuff you will hear next "shiny" and "best ever" gears that will make you itching to buy.

Can confirm. I ran my Sierra-2 L&R plus Horizon C (and other channels) with my Yamaha RX-A3060 for months with zero issues. None. I've since reconfigured to run my front 3 with my Outlaw 5000, but I did not really need to switch. You will LOVE the Yamaha receiver + Sierra LCR fronts combo.

If you ran your entire front (LCR) with vitually the same AVR I own (3060 is just 10 wpc more), then I should have zero problem running just the Horizon center with the RX-A2060. Thanks so much for sharing your experience!

Our Horizon and Towers are an extremely easy load to drive for basically any decent amp or receiver. Your Yamaha can run the towers and horizons 24/7 without issue.
I'm not sure about the 2060 but the newer RX-A2080 lists ratings for dynamic power into 8/6/4/2 ohms which implies that they test their amps under those conditions. I've been looking at an upgrade from the RX-A660 for exactly that reason. I may just contact Yamaha and state the question a bit differently, "I'll buy the 2080 if it has the ability of running speakers with Ascend specs, OK ?" I'll bet that they say "yes".

Just wanted to check with Ascend owners who use Outlaw 2200s to power their LCR and if you have had any issues with this arrangement. I am assuming not, but wanted to double-check before shelling out the $ for another monoblock.
if you already have 2 monoblocks to power the L/R your yamaha can power the center with no problem. you can even power all L/C/R no problem.
i have a denon 4200w which has lower power rating than your yamaha and it powered my Sierra raal towers L/R and sierra raal horizon center no problem, the amp ( ati2005 ) makes it louder at the same volume level though.

I might be misunderstanding your post.

If the system is calibrated correctly it should be the same output volume at the same volume level on the avr would it not? Just as an example, -10 mv on a receiver or pre pro should be 75db avg/95db peaks whether or not you have an amp or not.

this is what i know,
with the s2's i can go as low as -10 on movies, sometimes even 5.
with the towers the lowest i've gone is 19 and went back to 24.

You are talking about the difference in efficiency, the tower being quite a bit higher so it will play louder with the same wattage vs the S2.


I think what jsc79 is saying is that if calibrated in the AVR they should have similar output at a given volume setting.


So, did you rerun the Audyssey calibration after you swapped the S2's & Towers?

I also have the Denon 4200...

I had a similar experience before when I had my pioneer elite sc 27. I ran the pre out to a Parasound 5 channel...also NAD 2 channel and currently have a Harmon Kardon Citation 5.1 Bridged. I don't have the parasound or Nad any longer as I was testing which dedicated amp i wanted to keep.

I noticed the volume difference running a higher watt dedicated amplifier compared to the AVR. Definitely have more headroom with the extra power. I did run the room correction on the pioneer and audysey with denon to correct the higher volumes in the front and center channels.

However if you wanted more power to go towards the Center you can also control the DB level manually since most of the dialogue is coming from the Center channel. now if you did want an even output the audysey would measure the distance for you so the Center wouldn't overwhelm the left , right and rears.
