Up to $4000US tower speakers for Jazz and Classical Music

The BMR towers are superb value for the price.  The only thing is I'm not sure there's a home trial period, but you could definitely look into it.

For Jazz music simply buy an old pair of Alon speakers.  They are open designs, fast, have a beautiful tone, etc.  The price for them used is fantastic also.

These fit in your sweet spot:

Thank you ALL for your responses! even pointing out brands I was not familiar with; so many possibilities! will look into Tekton Speakers (particularly the double impact SE or the Electron SE), the Vandersteen 2CE Signature II model, Spatial Audiolab, Dali, and the Ohm Walsh. Thanks to Twoleftears for pointing out “The Music Room” website, which I was not familiar with. There are some interesting speakers there as well and they do offer returns which for us is essential. You guys made it harder! Definitely not interested in the subwoofers route, but will try to narrow down the tower speaker options. Thanks again.

Here is another thought. The Ascend Acoustics Sierra Tower. Lovely sound, especially if you choose to upgrade the NRT dome tweeter to the custom RAAL ribbon tweeter which adds an effortless, airy top end that is lovely for classical and jazz. It plays down nicely into the mid 30’s and the cabinets are handsome and slim. 7 year warranty and bamboo cabinets. The sound is quick, articulate, and beautifully balanced. $3400 a pair.

Dali Opticon 8 mk2 is stronger contender in your price range. Trusted name with science and innovative technology behind. 

The Polk Audio Reserve R700 has been getting alot of good “press” recently (YouTube, etc.). They appear to be well made and have excellent response at both ends of the band pass (apparently can pressurize the room in the sub bass area, so no subs may be necessary).

Cheers....

Off axis midrange and hi-freq is better in the later models than the early ones. Eric has addressed this weakness in the design. I find the speakers to be forward sounding in soundstage not recessed. Vocals and other instruments are right here, not in the back. I have compared these speakers directly to Magnepan MMG and Vandersteen 2CE Sig ll with stereo subwoofers. The quality of sound is the same with both, but the Tekton is foreword and with the gi Vandersteen the instruments and singer is behind the speakers. Tekton has more bass, more defined. I don’t think the midrange or tweeter are problems, they sound natural. The only issue I have with the Tekton Double Impact is that it’s the first speaker I have had that will make bad recordings sound bad, good recordings good and really great recordings sound tremendous. Whatever quality level of electronics one has the Tekton will reveal in brutal honesty just how good it is or how bad it is. This is true about the quality of the recordings.

Hi @2psyop ,

Reviewers say that the tweeters being directional results in the high frequencies not spreading. How does that effect the sound image in terms of width, height, depth and 3D in comparison to other speakers?

You have the experience to know actual monitor speakers are designed with a different presentation for a reason, good. Judging by the description of your systems current presentation I'd say it ain't broke. 

I agree with dekay's suggestion.

I have no experience with the SVS brand. I understand they offer a trial period and easy return program. 

Your 6000A has preamplifier outputs for a subwoofer. Long interconnects from Blue Jeans or Monoprice cable are fine. Competent subwoofer/s do not need to be matched to speakers and will work with future speaker upgrades. If your amplification provides enough power to your speakers using high pass filtering should be a matter of your personal taste. Good luck with it.

Lots of suggestions, but most posters overlook the fact that you want to purchase from a reputable store that offers 30- or 60-day money back return privileges, i.e. Crutchfield, Audio Advisor, Music Direct.

Over here there are several very interesting models:

Shop Audiophile speakers from The Music Room (tmraudio.com)

These have a 14-day in home trial period.  Look at the Canton, Magnepan, PMC, Dynaudio Contour--you can find some excellent used speakers under 4K.

This is Magnepan territory.

I understand your dilemma. Honestly, buying on guesses could net you a lot of speakers that are good, but not right for you. There is nothing worse than getting some brand new, expensive piece of equipment and hearing how it is great… just like the reviews, but misses your mark.

I recommend thinking about a road trip to the nearest city. Make it a short vacation you and your wife. Also, make appointments at a couple high end audio stores. Typically a speaker line will have a house sound… so you don’t have to hear the exact one on price.

After getting season tickets to the symphony ten years ago… I found myself abandoning the path I had been on for over thirty years and refocused on having a musical system. I was immediately drawn to Sonus Faber for their uniquely musical qualities. I am now on my third pair.. moving up their product line when my finances allowed.

There were actually to sides to my migration to a really musical and detailed system. I slowly swapped components to all tube components.

You have a big room so the kilpsch  speakers might work they need lots of room spend some time listening  before you purchase  those trust your professional  ears!  I generally  shy away from horn loaded speakers.  

I too dig Revel Petforma3 F206. I have a set and listen to Jazz. They are hooked up to a Naim Uniti Nova not lox. Also klipsch Herritage.
If only you could demo these and others.

Some great suggestions here ... please check into Salk

As mentioned above, an open baffle should not be missed before spending your budget. You may never go back. 

Monitor Audio Silver 500 G7- excellent review in recent Stereophile!

I also listen to a lot of classical (and jazz).

I would encourage you to check out open baffle speakers.

Spatial Audio speakers are highly regarded, as @81m800m800m suggested.

I’m not familiar with all their models, but the ones I have heard are excellent.

I have Emerald Physics 2.8 open baffle speakers in my system, and while OB speakers fill a room differently than a "box" speaker, they are something to behold. Absolutely exceptional for classical. I’m not sure I could ever go back to a traditional "box" design, to be honest.

I also have a pair of Tektons (Enzo XL’s w/ Be tweeters), so I am familiar with their design and line-up. Not a bad speaker, but again, OB speakers are hard to beat (at least for what I am looking for out of my system). This is predicated that you have the space to position them and the room to allow them to "breathe" (which it sounds like you do).

The Tekton Electron SE's have what you are looking for.  They have the "open, airy, detailed" qualities you are looking for yet have a very potent low end for full scale orchestral works.  Dual 8" SB Acoustic woofers/ported design can move plenty of air-no subs needed.  They will be well under your budget  and I can't imagine you being disappointed or returning these speakers,  The Double Impacts would also fit the bill--even more dynamic.  But they are BIG speakers and can dominate a room visually speaking. The Electron SE's are quite a bit smaller and may go even lower or at least as low in the bass.

Ignore the Tekton bashers on this site.  They are hell bent on hate and have nothing helpful to offer.

Check out Spatial Audio Lab. I'm not familiar with the Q accoustics to tell you how they compare with the things that you like about those, but I really love my M5 sapphire models. They are open baffle speakers so placement is important, but if you have the space to situate them they are pretty special in my opinion. Maybe I just don't have the experience with other speakers but I really think you might be hard pressed to find a box speaker in the same price range that could best the quality (if not quantity) of bass. Reviews are few but Steve Gutenbergs channel has one as does "new record day"

I have the Revel F206s and enjoy them more than many others I’ve owned, including a pair of $9k Audio Physic Avantis. They do undergo a lengthy break-in period during which bass and coherency improve. They are very detailed and revealing but remain very listenable and “musical” which can’t be said for many detail-centric speakers. Bass extension is decent into the 40Hz range, so a sub in not necessary in most cases. The real star of the show is their tweeter, which is the best I’ve encountered in a non-DIY speaker below $6K/pair. It is almost indistinguishable from some beryllium units. 
 

Another speaker you should add to your shortlist is the Polk Reserve R700. 

Why stay away from the Tektons?? 
 

Totally disagree even though I don’t have them anymore. 

I agree with mapman above! Ohm Walsh speakers are indeed amazing! 3-D room-filling sound from any spot! I have a pair of the Sound Cylinders. 

Learn how to properly implement a pair of subs.

You have a large listening room as well as exceedingly well reviewed gear (amp/speakers) in their price range.

DeKay

Ohm Walsh. 

My recommendation: stay far far away from Tekton.

On Crutchfield, probably the Dali.

Even better at Music Direct, the Vandersteen 2Ce, in your price range.

Look at the Tekton Design models (many to choose from) 

if you don’t mind shipping them back to the manufacturer if you don’t like them. I have the Tekton Double Impact SE and they run great on low power tubes. They are an exciting speaker to listen to. I think they are very neutral and have natural midrange and treble and tremendous tight bass. Tekton will paint them any color you like. Also the Klipsch Forte III would be worth a listen.

I also have Vandersteen 2CE Signature II speakers and they are AMAZING for the price.
