Title: Spatial Audio Hologram M4 Turbo OB speaker - A Review
Post by: Whitestix on 15 Apr 2016, 12:45 am
I received these speakers about three weeks ago and with a bit of run-in on them, maybe 75-100 hours, and I am prepared to say that they are simply stunning speakers.  I have a bit of a bind in my room in that I only have 2-3' from the rear wall to position them, which is about what Clayton Shaw from SA said would be workable.  I heard his former design, the Audio Physics OB speakers, at an audio show a couple of years ago and was very impressed with them, but was waved off when I learned that the AP speakers needed 4-5' of clearance to perform their best.  Clayton now has his own company and the Holograms incorporate major design improvements from his earlier designs with Audio Physics, not least of which is their performance much nearer the back wall. 

Most notably, these do not sound like any speakers I have ever had and I have had a nearly a dozen over the past decade in my room, but admittedly no OB speakers.  I listened to them with a pedestrian SS amp to break them in (note:  don't form any opinion of them until they have a least 50 hours on them) and then swapped them for an excellent 6L6 tube amp with 6 wpc.  With the tube amp (and my tube preamp), these speakers just simply blossomed with a huge soundstage and a very warm liquid sound.  There is no question that the speakers mate very well with tube amplification.  I then swapped my venerable CJ MF-80 SS amp into the system thinking that they might lose the holographic soundstage and warmth, but as it turns out, the CJ amp provides a bit more control on the LF response and gives up only a bit of the warmth and liquidity that the tube amp provided.  So, my take is that they respond very well to both tube and SS amplification, but with good gear, reveal provide much better performance. 

The M4's have an effortless, uncongested sound to them that seems very coherent from the LF to the HF.  They are neither forward nor laid back, they just make the music sound tonally correct and realistic.  If I had more room for placement, I might consider the M3's, which go down to 32hz whereas my M4's go pretty flat to 45hz.  No worries with the M4's, I am very happy with the LF response and if I get motivated, I might hook up my REL sub to catch that lower octave.  No doubt due to the open baffle design of the speakers, I sense an openness to the sound that I haven't ever experienced with any speakers I have had.  They are very detailed, with a clarity to the spittle sound of Miles' trumpet and a palpable leading-edge attack to Ron Carter's  double bass that just is simply amazing.   The sound from bottom to top with these speaker continues to astonish me the longer I listen to them.  If think they might tend to a bit warmer presentation, to my ears, but only slightly so.  Overall, they are very balanced. 

Clayton has a generous no-hassle 30-day trial with these speakers because it is a fair bet that few buyers will not be very happy with them.   I am just a guy who has loves jazz and has been in the quest for great sound in my system for the past 45 years so that is my point of view in this review.  I am not going out on a limb in saying that I think Clayton has significantly moved the ball ahead, from technological design and production standpoint, with his Hologram speakers.  I simply marvel at the pure enjoyment I am hearing with these speakers... just such pure enjoyment.   

For $2K for the M4 Turbo S version, I can't fathom a more fulfilling audio product than Clayton's speakers.  I urge my music-loving friends on this forum to think outside the box (speaker) realm and consider what Clayton has created with his well-engineered and beautifully-constructed line of of Hologram speakers.  At least, seek out his room at the next audio show and give them a listen.  Cheers, Whitestix

I have had my M3 Turbo S model probably just a few days longer than you and after testing them for 3-4 hours the first night to assure all was well, I moved them to a spare bedroom and wired them up facing each other out of phase and put blankets over them.  I let them run 24/7 for almost 10 days so right now I am right at or just over 300 hours.  So far I have tried them with tubes, A/B SS and Class D.  While each of the amps have their strengths, like you I found that the Spatials respond very favorably to power and control.  As they are in my family room and not my dedicated room they are only 36" from the front edge of the baffle to the rear wall and in this position have more than enough bass and probably get very close to the 32 hz mark.  I have an ACI Force XL sub set up in the system, but as yet have found no need to turn it on.  Give them another couple hundred hours and the bass will get even better.  As you said a bargain at their price in the current price market that is "high end audio." They are really worth a serious listen for anyone looking in this price range or higher.  The cost of shipping them back is a whole lot less than what you would lose on buying a speaker new that you decided you couldn't live with.

"Such pure enjoyment....I can't fathom a more fulfilling audio product than Clayton's speakers."

Could not agree more. I recently moved up to the Turbo S from the base model...what you get at this price point is just hard to fathom. Wonderful speakers that will sing with nearly everything you throw at them - tubes, class D, hybrids, low powered, high powered...They just keep delivering music. Can't imagine going back to a box design after these...

Be prepared to be floored.  $3k shouldn't sound this good and be full range.  Well, it should but I've never heard it until these.  Yes, they're really that good.

I am using the Modwright LS-100 preamp, but also tried my W4S STP-SE, with the two tube amps plus the Kismet, Nuprime ST-10, W4S mAmps and right now testing out another members Nord One Up  NCore 500 amps.  The tube preamp and the Nord's are quite a combination with the Turbo S's. I initially thought I would be testing the Spatials out, but the wife has decided they are staying.  My Nolas are OB for the mids and tweeters and bass reflex for the woofers, but full OB is a bit different.

What I have is technically better.   ;)   Fully balanced from input to output.

I have to take exception.

All a balanced configuration accomplishes is greater freedom from hum and the like, due to the inherent rejection of common mode signals, like EMI induced hum. This can be an advantage only when hum is a problem or is audible, otherwise the signal suffers twice the degradation needlessly. I say twice the degradation because it is impossible for a signal not to be degraded to some extent merely by passing through any electrical device, be it transistor, capacitor, resistor, transformer winding or whateverr. Since fully balanced involves twice the number of devices for the signal to pass through, the resulting distortion from this is doubled, all other factors being equal.

Is that technically better? Not in my books, but it is a very common misconception.

In recording studio work it is more likely to be necessary and the convenience of not having to trace and deal with hum is often worth the degradation, but even in that environment the same misconception is widely held. In fact I had a lengthy online debate with an otherwise extremely well informed engineer about this very subject a few years ago.

Part of the problem is that balanced connectors look so much more professional than the humble looking (and flawed-in-its-own-way) RCA connector. They click-lock into place and all that good stuff, but if you are in search of the ultimate sound, you want to keep the signal path free of needless complications. Hum is seldom an insurmountable problem in the home, but manufacturers know the cachet associated with balanced and are only too pleased to service that perception.

I have to take exception too.  If you look at the measurements of my equipment running balanced mode, there is an obvious advantage over SE.  That's why I do it...not for special connectors or any of the typical audiophile crap.

But DAC chips are frequently balanced as it makes implementation easier, and switching amps are all balanced too... so if that's your system it makes more sense to me to use a balanced preamp nad keep it all balanced in to out.

Has anyone had the opportunity to compare the M3 and M4 side by side?

Are we only talking a difference in low end extension (32hz. vs 40) or are there other significant aural differences. The Turbo-S version of each seems to use the same compression driver so I would expect the mid/upper frequency performance to be similar as well.

I have a fairly large open concept (living/dining/kitchen) space to fill but in terms of where I position my equipment I prefer the form factor of the smaller M4. Would the M4 with sub reinforcement provide most of the performance of the M3?

However, considering that there is only $500 difference between the Turbo-S versions of each, which really represents the best value proposition?

Comments?

I am sure these speakers are great and fine just as they are.....however, I am a tweaker.....never satisfied till I wring every once of goodness out of something.  If I were going to order one of these.....and I probably would if I were looking for speakers in this price range....I personally don't see anything better out there......here is what I would order and do:

1. Order the speakers with external xovers and no wires connected to the drivers.  This allows you to change the xover parts to better ones (no way at this price point can he use the worlds best parts).  You can then change the wires to the drives to better sounding wires and also hardwire directly into the xover eliminating the input binding posts.  All of these changes including have a damped external xover (off the floor) would make a substantial improvement. 

2.  I would damp the back of the big woofs with EAR SD40AL.  The woofs have a stamped frame and killing the resonances of the frame will result in cleaner sound.

3.  Make a rear brace that runs from the base all the way behind each driver and attach it to the top of the baffle.  This will stiffen the baffle and make for faster transients.  The original version of the M3 had a brace done like this but he dropped it (probably for money reasons....maybe for sonic reasons....was kinda thick).   You don't need the brace that thick.....even just 1.5 inches would be great (I would use 13 ply plywood with green glue in between two layers).

Of course, probably none of you would want to do these things: voids warrantee, loss of resale value, fear, does not look as sweet, etc.  However, for that one person that can understand what I am saying and wants to take this speaker technology to another level.....well, have at it.

Yes, all of these tweaks have been listened to by myself and countless others.  They all work.  Everything is made to a price point.  Spatial has more expensive speakers with better drivers, xover parts and baffles.  I prefer to take something affordable and upgrade it myself.....a lot of fun and very rewarding. 

Now back to your regular programming.

Magnet and frame all coated! I let the compound dry over-night so it’s completely cured. VB-1 is non-toxic, it’s not harmful to get on your skin, and there is absolutely no fumes or nasty smell to deal with. I get it directly from Cascade, so at the wholesale price per gallon, the extra cost per application (speaker cabinet or woofer frames) is minimal. The benefits are much greater than the small initial cost. I used to use adhesive-backed asphalt or vinyl based sheets on the interior walls of my cabinets. As far as damping properties go, the VB-1 is superior. It also sticks better, and is easier to apply.

I have the M3Turbo and  s compression driver. I have greatly improved the Xover Clayton did a excellent
Design I just used  higher end parts .for resistors swapped out yhe Mills to Mundorfs top Supreme instead of one  30 ohm , 2-150 cut the ends off and soldered Neotech  Single crystal copper leads,
On top the Big 1.5 capacit or did have the new Mundorf supreme Evo silver gold oil but slightly tipped up
But great detail and resolution. For balance the Audyn True Copper capacitor  I like better then the Jupiter
Or Basic Duelund for balance, the Duelund Cast is Better but is huge and 4 the cost.
These Audyn Copper caps are Huge I took 4 pieces of plastic tubing and 2.5 inch screws did the soldering
Then screwed back in it sticks out the back 2 inches no big deal. Also I placed Dynamat all over the back
This increased performance in evenew better focus.  Also AVM fluid applied yo the crossover all leads and solder joints wires except the resistor even better focus look it up Audio Vibration Magic give it a hour to dry

If you upgrade a stock xover using the same values of parts (including size of coil) then you will have no differences in any measurement.  Most all who have done mods to xovers have no knowledge of technical things but all will tell you that better parts sound better.  It is very simple to replace parts.  If you use a bigger gauge coil then stock then its impedance may effect frequency response slightly.  But even then it is minor compared to the better sounding part.  Don't be scared away by the techies.....very simple....."even a cave man can do it".  However, it is always good to measure a speaker before and after mods.  Measurement mics and software cost very little.  Again....cave man friendly.

  I heard the Spatials at Axpona & they really do seem to be as good as everyone is saying.  The room was consistently busy during our time there, so I was a bit hesitant to make requests (most music in most rooms really wasn't anything we were interested in).  So although we dipped back in several times, I didn't manage to hear anything particularly complex & dynamic like full orchestra or anything really rocking.  Still, they did play everything we did hear exceptionally well.  The only caveat is that they did have a much narrower sweet spot than some other rooms--my girlfriend wasn't impressed at all when sitting next to me, but enjoyed them when we traded seats.

Sweet!   :thumb:


Have you listened at all?  You can still get a feel for what they do out of the box.   :drool:

I've got them about 31" from the wall (as per Clayton's suggestion) and toed in slightly. Obviously they need more burn in and probably a little placement testing, but out of the box a huge soundstage with some pretty jaw dropping imaging. Treble is bright and bass seems to want to break out but I think the speakers just need time and current running through them.

OMG! Those are beautiful. And I am sure they sound just as good as they look. I see there hasn't been any updates on this topic since 05/10, so I figured to get this going again. I stumbled on to Spatial by accident last night when googling reviews for Red Dragon Audio and am VERY interested. I have gone through Omega 3XRS's and now using Tekton Pendragon's but am moving into a brand new house in 6 months and even though I love the Pendragon's, am looking at downsizing and these M4'S might fit my needs. Plus it gives me an excuse to just buy something new to try.  :D
