Sometimes, you are not the customer and that's OK. This isn't for you. Having other areas of research and topologies available in the marketplace are good, if we want progress. These discrete solution give more "levers to pull" versus chip dac and they can get some unique performance...

We have all of the documentation on this from the vendor. I can look up the exact specification. I have the MSDS sheet on the MDF but don't see reference to the E series standard that you mention. This cabinet factory does all of the bowers and wilkins models (except their 800 series) and...

My understanding is that the original version had the cabinet made in china at the factory that we now use (for PS Speakers) but they had some challenges making these very complex cabinets (they use vertical laminations of plywood layers and then paint/veneer over that). I believe that the...

The issue with "phantom center" is that it exists only for the person sitting right between the speakers. As soon as you sit to either side, the sound will pull significantly towards whichever speaker you're closer to and not be anchored to the action on the screen. This is why there are...

Well, I don't mean to sound defensive. There are some great speakers on the market (some of which are very aggressively priced) but I don't think that additional choice is a bad thing. My friend in town is getting a pair of Blade 1 meta next week or so and I'm looking forward to hearing those...

Do you want to build a kit, solder and supply/build the box and consider that for $0 (like your time is worth nothing). If you enjoy DIY, that’s one thing, but this obviously isn’t apples to apples. I like DIY but to build a nice box, and make enough profit to resell and support the product...

No, not +\- 6 db. -6 db referenced to 200 Hz in the on axis response. This is the same as KEF and many others do. Your commenting about 60 hz shows a lack of familiarity with reading a graph like this . +\- 3 means the same thing WRT bass extension. +/- 1.5 or -3 db is the half power point...

I'm not sure where you get the 60 Hz from. If you look at the -6 dB point, it is 32 Hz, which is on-spec. These get flat into the high 20's in-room. Yes, you can also add a subwoofer but "need" really depends on what you're listening to.

Well, the difference in reconstruction filter is more about the time domain than frequency domain performance (e.g. apodizing and linear phase, minimum phase and even more so in NOS dac etc). You don't need hearing to 20kHz to hear the (albeit subtle) differences in DAC reconstruction filters.

Yeah, I worked for Dan as my first "real" audio job at Adire Audio, a company that he was the cofounder of. Dan has been a hired gun for a bunch of high-end speaker and headphone products and is a very good (and creative) engineer.

I haven't don't the video yet but was going to when I get in the next set of production samples. A few comments on the video: The passive radiator tuning on these is 35 Hz. Depending on the room loading, 30 Hz will be audible but, realistically decent output is at 35 Hz and above. For some...

Well, the Polk looks like a very good speaker for the money. They are using 5.25" woofers instead of 6.5" woofers and have a lot less bass output capability and a pretty high non-linear distortion in the midrange and I expect that they sound pretty different. Polk R500...

Yes, when there is a bad CSD (like some compression drivers or certain driver designs can have) it can be a cause of grainy/hasky sound on certain program material. I think the reverse can be true and an example of that is the improvements that KEF made with their meta drivers or in the...

Well, this is definitely off topic in a thread about a speaker review. For what it's worth, there was no external I2S connector standard before ours and we published the HDMI pinout. I think Audio Alchemy may have done something similar with an RJ45 connector in the past, though I can't say...

Yeah, my history goes back a ways on the bigger drivers. My father did a lot of work on those with David Graebener (after David's work on the Carver ALS with Jim Croft). Here is a little think that I wrote about them. https://www.psaudio.com/blogs/copper/attack-of-the-20-foot-tweeter Planars...

It's actually $3500 or $4000 with the matching stands. You have to keep people guessing. ;)

As a point of reference, here is an in-room measurement a customer shared on the PS forum of a pair of FR10 as measured by a dirac live/MiniDSP setup. https://global.discourse-cdn.com/business4/uploads/psaudio/original/3X/9/f/9f22cb5b369d8f35f5f8e17b582f1823f0f7fb9d.png The speakers were...

This got a little spicy overnight. I can see why this debate was prompted though and a good spirited discussion about these things is worthwhile to a lot of readers to better understand what's going on. I too wish that we had launched these at a lower price as I'd love to get them in more...

I do love the purifi stuff and have huge respect for what they're doing. However, we want our own "keys to the castle" and I want to continue understanding and improving our own drive units to iterate on future models and give a consistent design through various models.

This model is our smaller one (about the size of our Philharmic HT tower), actually 1.5" shorter, .5" narrower but 4" deeper than yours. The FR10 is tuned and plays lower but is quite a bit lower sensitivity (so we've traded off sensitivity for deeper bass extension in a somewhat similar size).
