New Revel Performa4 / Arcam Radia speaker line-up -- with Anechoic EQ

That's one track. Don't make me ignore you.
What? That was literally three different tracks. I can go through all of Jean's reviews of multichannel releases, my recollection is not that the center channel is routinely poorly utiluzed.

Based on the measurements of every other NHT speaker I've seen I personally wouldn't expect much. Certainly nothing on par with Revel. But who knows, maybe those are the exception?

Edit: Oh there are measurements for the 3.3, such as you get from Stereophile anyway:


Not terrible, but not amazing either.
Have it your own way. I'm not selling them, so I have no vested interest in convincing you.
People that have heard them know what exceptional speakers they are.

If you think three is a statistically valid sample, you should talk to @Oddball 's kid.

Like I said, my recollection is that these are quite representative. How many do you want me to put together? 10? 100?

Let's disagree in another thread.

Right, the older one seems to understand the concept theoretically, but then teenage age is really confusing for the young brains so it's a mixed bag.

My view is you either do it right or don't for LCR. Can cut a bit from others if multiple big-er subs are are involved. It's not difficult or that expensive to get your Atmos in 50hz range as well that will help with bass localization in few tracks that actually did care about that.

Oh, forgot to mention Dirac ART - it is a thing that makes all this all that better ;).
 
For those debating the 2 way MTM center, I had the Revel Concerta C25 and later upgraded to the Performa C205. In my small home theater, which is 12' wide and with a listening position about 7' away from the center channel, I took center seat, left seat, and right seat measurements of the C25 and overlaid them. The thread is here:


They really aren't that bad in the real world of my room unless a max 3dB difference at 2KHz means the world to you.

One day I will get around to repeating the experiment with the C205 with and without DRC applied.

According to their website NHT have moved away from incorporating subwoofers in to their tower speakers because they noticed customers were adding subwoofers to their integrated subwoofer towers.

Nice, thanks for that. Always great to have real data. Although your setup is actually a worse case scenario than most, I think. My setup, for example, is 9 feet away and the seating area is not that wide. And of course there's the fact that when you start getting well off-center like that you're also going to have the problem of being significantly closer to the L than the R speaker (or vice versa), which is likely a bigger problem than the small tonality shift from the center.

Yes, you got subwoofers in the integrated towers so that you could then add another sub or 2 to smooth out room modes and be able to have a higher level of less distorted bass.
In my mind, taking that away makes them total idiots and Bean Counter cultists.
I never bought any NHT speakers in the past (because I couldn't afford them).
But now that I can, they have done something to insure that I never will.

Most of the previous solutions for "passive" towers were not drastic enough. Kind of half way, so yeah real subs where still required. Some have gone out of their way to create a true monsters, but then positioning is limited for these integrated solutions.


Then there are active speakers with their active bass modules. Genelec, Kii, etc.

And then there are various ways to manage and EQ bass. So good luck finding your way through. I am happy with what I have at the moment, so no more experiments for follow for a while.

Yes, this was brought up in the thread. I tested and confirmed that left and right speaker proximity in such a small room is in fact the biggest problem.
 
Not with bass heavy music. I blew a BMR woofer.
Was that V1 or V2? The larger woofer (scanspeak) of my V1s haven't had issues, just other tradeoffs. I'd love to hear the two side by side.

V2. It's not a complaint, I love those things. But one can only drive them so far...

If the Arcam Radia line is in fact the next iteration of the Revel Performa series as the referenced AVS Forum indicates, then Revel is following NHT's lead and also eliminating the larger drivers from their Performa line speakers.
It will be telling to see what other line(s) Revel will be introducing and whether they will be following the same philosophy of downsizing cabinet and driver sizes

I built a pair of DIY floor firing 12" ported woofers (FR 20 Hz-80 Hz) that are the same height (with the same 3.5 degree slope) as the original stands (and then put a thin pad on them and put my Dahlquist M-905's on top of them, keeping them more or less time aligned.
The DQ M-905's have a very small bass-resonance peak. At the system resonance of 60 Hz, the output is only about 2 dB above its average level in the upper part of the woofer’s range, and even that minor output variation was spread over almost two octaves. When the bass curve was spliced to the room-response measurement, the resulting composite frequency response was flat within about ±2 dB from 26 to 20,000 Hz. The horizontal directivity of the tweeter was only discernible in the room measurement above 10,000 Hz).
And Quasi-anechoic FFT measurements show an overall group-delay variation of about 0.1 millisecond between 4,000 and 20,000 Hz and 0.5 ms between 1,000 and 20.000 Hz, convincing evidence of the attention paid to the phase characteristics of the M-905.
So, I, too, have been happy with what I have for quite a moment. I may add 1 or 2 more subwoofers at some point in the future, but things have been "GOOD 'NUFF" for quite some time. And I'm a tad lazy these days (after some cervical vertebrae fusions and a few various cancer surgeries) over the last 3 years, I'm content to not mess with "GOOD 'NUFF" and just enjoy the music.

Harman designed these Arcam Radia/Performa4 speakers to be used in a system with their processors and amps.

Harman will have 2 Arcam Radia AVP/AVR models that store the speaker ‘anechoic EQ’ data. These are the priciest models, of course. Plus, 2 new Radia amps, to match. Info from HomeTheaterReview and What HiFi.

Here’s some info on the AVP45, a 16-channel processor:
  • 16 balanced outputs, 16 unbalanced outputs
  • Dirac Live Room Correction (Dirac Live Bass Control and Dirac Active Room Correction upgrades available)
  • supports Dolby Atmos, DTS:X, Auro-3D, and IMAX Enhanced
  • Roon, AirPlay, Chromecast, Spotify Connect, TIDAL Connect, and Qobuz.
  • Bluetooth 5.4 with Auracast
  • HDMI 2.1a, 8K-ready; eARC
  • Matrix Channel Assignment to accommodate all kinds of speaker layouts
  • £5299 / €5999 / $6000

Pair the AVP45 with the Radia PA9 amp, and you’ve got 9 x 100W of Class G amplification to power even large multi-speaker systems. This duo gives you the flexibility of separates while staying within the same design family. £3499 / €3999 / $5000.

And for those looking to expand beyond nine channels or power second zones, there’s the more compact PA4. It delivers 4 x 50W of Class D power from a low-profile chassis that’s even wall-mountable. £899 / €999 / $1500.

So, an AVP45 and PA9 and PA4 amps drive 13 channels, with 3 left for subwoofers. This 3-unit package is £9700 / €11000 / $12500.

ASR members would probably power this processor with acoupla Hypex/Purifi multichannel boxes from a reputable dealer, at less cost and more power.

A quick perusal of prices on Crutchfield USA shows the AVP45 is ~competitive for 16-channel processors, with >= 3 subwoofer outs, at $6K. The Marantz AV20 is 13.4-channels for $6K; the AV30 is 11.4 for $4K; the Anthem AVM90 is 15.4 for $7.5K; the Marantz AV10 is also 15.4, for $8K. None of these can store the speaker’s ‘anechoic EQ’ data, of course. (Although, maybe Marantz/Denon units will in the future, as Samsung entities....)

BTW, I believe the JBL Synthesis SDP-75 processor can also store the ‘anechoic EQ’ speaker data. This’ll setya-back $27K/$33K/$37K for 16/24/32 channels, respectively. Makes the Arcam AVP45 seem like a steal, eh?

Posts to follow will assemble some Performa4/Arcam Radia systems with the AVP45. Then posts will preview the AVA35 receiver, which also stores ‘anechoic EQ’ speaker data, and includes amps, for £5999 / € 6999 / $7000. :cool:

Per post #1,

'Revel is set to make official announcements in the USA on March 1'

Has Revel USA made an announcement ?
