Looking for new speakers for large audio room


I’m looking for new speakers that are big enough for my listening room which is 9x6 meters and my current speakers are Avantgarde uno series two loud speakers and not getting enough impact from the woofers.


I’m looking for speakers in the 30K to 20K price range.

shawarma, what is the ceiling height? That is certainly a larger room.
To get real low end in a room that size you will need at least four 15" subwoofer drivers. You would need Trios and subwoofers.
8 or 9 foot (depends on ceiling height) Sound Labs with four 15" subwoofers will work but that is pushing you price limits. Magneplanar 20.7s will work well unless you like listening above 95 dB. You could afford those and subwoofers. Line source speakers work better in larger rooms. Their volume does not drop off as fast with distance.

Edit: ceiling height is 2.8 meters in height

using two REL S/812 woofers in my set up

I have auditioned the Magnepan 30.7 but my pass labs XA 60.8 amp isn’t powerful enough to drive them loud enough in my listening room



what about trading out your subwoofers and getting something like a pair of Perlisten d215s's.  Given the size of the room, that might resolve the issue you are having.  
Add a couple 15" to 18" subwoofers. Spread the subs around to get better coverage.
Try to audition one of the larger Legacy speakers. Even their largest will be easily driven by your Pass amp.
If you have corners, Klipsch Corner Horns would provide a huge sound stage plenty of volume and fill the space for half the price.
@shawarma  Classic Audio Loudspeakers makes two speakers you might want to look at. The first is the T1 and the second the T3. They are 98dB so will be able to fill your room with a moderate amount of power (I suggest about 100 watts minimum). They are also full range and 16 Ohms. The midrange drivers have no breakups in the audio passband and are field coil powered, so they are very fast and also very smooth.


Since standing waves are an issue in any room with regular dimensions I would supplement them with a pair of subs placed asymmetrically elsewhere in the room to break up the standing waves. These subs should not be active above about 60Hz or so.

When I heard my first horn speaker it was the Avantgarde Uno Fino.  From there I went on a mission to find a great horn speaker.  I came across a company called Viking Acoustic.  After talking to the owner ( David Counsell) and visiting his studio I settled on Viking Acoustic Grande Voix  Dual Horn speakers.  All I can say is that they blew away my previous Wilson Audio and Sonus Faber Speakers.  Take a look at the website and give David a call.  They are phenomenal!
Perfect for Magnepans. At least 1.7is. but you have to have the power for them. They will absolutely blow you away in big room like that. 
Get the used pair of Egglestonworks Vigintis for sale here on Audiogon (no, they are not mine, but I do own a pair).  They are $19,900.

With moderate power (300 wpc), I have never, ever felt the need for a subwoofer-- pitch perfect bass-- that you can feel when it's part of the music, and very pleasant dynamics and balance overall.

Fremer really likes them too, and Mikey, well, he can be fussy.

More bass and a larger room, keep the Avant-garde speakers and upgraded the subs
Look into D+S tech labs Hathor speakers with built in 1000Watt subs for just under 30K you pick the wood finish, call and talk to Bill Daniels he will probably even come out to help set them up if you ask.
The majority of these speakers if any at all  listed won’t accomplish what your looking do to based on the size of your room, the only real way to pressurize your room with bass and keeping your Pass amps is to upgrade you subs to larger ones and add room correction to dial it in.
I just bought a pair of KEF Reference 5’s.
so far they have been great!

All the best.

Here’s what I would do… at that price point, buy at least two, preferable 4 more Rel 812’s and stack them to do the stereo sub line array. Bass will never be a consideration again. It will blow you away and you will have no need to add anything else. Plus, it looks cool as sh!t…
The Ilumnia  Magister MK2: the best speaker I ever heard. My living room is practically the same as yours! Very beautiful dept: look at :  ilumnia.be
Most of the speakers brands most of you recommended aren’t being sold by any local dealers in Thailand and. If they were bought online the price would be doubled or more for imported audio gear so I’m very limited most of them I have demoed most of the loud speakers 

local dealers sell their products the same price and usually have great discounts and no trade up program for most places even 

For example I had a vintage Bryston 4B amp and the dealer would not take trade up because it’s too old of a product.


and very small used market for audio gear.
I second the vandersteen Kentos. They have built in powered sub and I think your Pass is enough to drive them. It could be though that you have a twofold problem. Even with the high efficiency system you have, the room may just be too big. You might need more power. 
@geof3 

How does the stereo sub line array differ from the DBA where you place them around the room? Does the line array work like the DBA in canceling out room modes? Thanks 

Ron 
Edit: my ceiling works as a baffle with wood going across if it’s affecting the bass.

cant Demo the vandersteen the dealer can only order them;)
Common clearthinker, why not!

Given you amplifier's power I think  Atma sphere's recommendation makes the most sense. Without a line source dipole I think horns will work best. However, with subwoofers your amp will drive Sound Labs 845's but you would need two more subwoofers for it to work really well.
I use JC 1's which are Class A to 25 watts and I rarely use more than that. I also believe your Pass will push a lot more power just not in class A.
Hello,
+1 for the extra subwoofers. If you are not going to go that route I would go with one of the KEF blade 2s. They have side firing woofers that creat a ton of bass. If you don’t believe me go listen to a pair in a room half the size. These things need breathing room and you have it. Also, with such a big room you want the music to sound good outside of the perfect listening chair. These do it in spades. I love the KEF Reference 5s. You would be better off with the blades. KEF has a subwoofer, The KC62 that plays down to 11hz in a one foot square box. It’s like having two of these awesome subwoofers in each speaker. I don’t own KEF Blades but I have heard them at a brick and mortar store close to me. https://holmaudio.com/This store lets you try stuff out in your home on your equipment for free. No buyers remorse. I hope this helped you out. 
Here is a good list for you:

KEF Blades - Gershman - Dynamakkit - Vivid - Estelon - Ascendo - GT Audio in New Jersey - Vandersteen the new model sevens mark IIs are coming out shortly

Happy Listening


Most of the speakers brands most of you recommended aren’t being sold by any local dealers in Thailand
Due to the size of your room unless you have a very high powered amp horns of some sort are probably in the mix. So do you plan to only work with speakers that are available through dealers in Thailand? This sounds very tricky any way you look at it!
TEKTON just intriduced the MATRIX LS @ $18,000....but you have to tie all you furniture down ....stuff starts to move around the room.
TEKTON's Brand new MATRIX LS w/ 15 Beryllium tweeters. Bass you want....you'll have to tie your furniture down......Turn your music up and you could have a "new address"......check 'em out.
@ronboco it does, but potentially to an even higher degree as you have elevation in the mix. Also, and is recommended, the crossovers of each are slightly different. Take a look. It’s an expensive endeavor with the Rels though, and the S serie subs are designed specifically for this application. They work fine as singular subs but they are setup to daisy to one another and have mounting plates to tie them together as one. Shocking set up. It is a similar tactic used in live shows where line arrays are pretty much the norm.
Dutch and Dutch 8C. Half of that price range but will beat most. 

But you seem to be just right for Grimm LS1be. Those are endgame speakers.

Time to outgrow all the puerile preamp, DAC, amp banter. 
@shawarma
In your large space, are you satisfied with the Avantgarde uno sound with the exception of bass impact?
You really should keep those wonderful speakers and only add what your room is missing which is several subwoofers to properly pressurise that large of a room.  Most any new speakers you might purchase would still need those subwoofers due to the room size.  My main listening room is that large and I wasted time and money upgrading to larger speakers when in the end several subwoofers were the only thing that could properly pressurise my room.  Wishing you the best.
For that big a room, Klipschorns, Lascalas, Cornwalls, ...take your pick.....

@atmasphere yes I’m only working with dealers that already have the speakers in stock do to custom officers raising the tax to 200% or more of the speaker price so I’m incredibly limited to what speakers I’m looking for 
I have a pair of customized Tekton Double Impacts with ribbon tweeters in a large room and couldn't be happier. Tremendous bang for the buck. 
Are you replacing the Avantgarde uno series two? Thought you were just looking to upgrade. Those are some great speakers. Can you afford some Avantgarde's with bigger horns and 4 subwoofers?
The Persona 9h would do the job. I had the 7f and was floored by the bass passive speakers could put out, sure the mid and tweeter need to be matched to component en to by ear, but when they are oh baby!
A used pair of meridian dsp 8000’s will cure any bass problems and if you can get a special edition pair they really are very good.
