These lunch talks are becoming my favourites.

The lunch chat format has a nice informal feel to it,like a couple of enthusiasts just shooting the breeze.I enjoy them.Speaker design is all about compromises,with various strengths and weaknesses in different applications and configurations.Even when you buy a mega bucks design,they still have to endure compromises that the physical limitations will ultimately dictate.More refined materials and applications will eek out some performance gains,although with speakers having the highest distortion and colouration levels within the audio chain they will likely remain the most subjective element to the end user too in practice.

Hearing someone from a learned background discuss something I have only assumated from decades of incidental learning is reassuring what I have been doing in my crossover setups! . A good follow up to this would be correct electronic crossover implementation. . Another great lunchtime chat!

One of the best clips at PS audio so far... we can see the big progress in Chris'es elaboration. It suits him better to talk with someone instead looking at the camera. Congratulations to both Paul and Chris...

Great work on adjusting the angle of the camera. It's much better

The more I hear about passive XO's the more I like active ones ..! They really are the best you know ...

Oh, there's so much more that I wanted to hear about. Crossover design is the true magic in my opinion when it comes to speaker design. Just as Paul has mentioned before during the development of his new speaker, they are constantly tweaking the crossovers to get the sound they want. It's one thing to divide the frequencies, it's another to get the speaker to come alive.

Something no one ever seems to talk about with respect to even order (12, 24 db electrical) crossovers is the advantage of having a low DCR inductor in parallel with the voice coil. This preserves motor control of the voice coil and helps prevent ringing.

I definitely learned something new today

Another reason to audition the TLS-1 by HHR Exotics which is an updated Ohm F which is a single omnidirectional driver with a frequency response of 29 to 22,000 hertz and does not need a crossover, it is time and phase aligned. It was once called the best speaker at any price.

Definitely a step up in content complexity.

A discussion on the need for quality crossover components would be nice. I completed a three way crossover last year with a 24db slope where the cost per pair was $1600. $1600 was a bit more than the cost of the drivers, but worth it.

I've heard some fabulous full range speakers. Most used in hifi are 8 to 15 inches these days.

Nice mic for an open air sound even if fidelity isnt great. Paul sounds like hes over my left shoulder, Chris sounds like his voice is coming from his face. Also, Chris reminds me of my uncle, Chris. Same facial hair, same hair cut, same eyes, same face shape, almost identical voice, same name, and he aslo talks with his eyes and brow rather then his hands like Mr. Brunhaver here. Uncanny really.

I dont know electronics as well as the engineers that build crossovers but, how is the circut resonance delt with between a capacitor of the hightpass filter and the inductance of the driver motor? Or is the resonant frequency so far out of the frequency range being delivered that it dosent matter?

Infinity RSa's have a 10" mid bass. First it fires the bass tone and then out of phase it fires the mid range into a 10" woofer. I would like to know, why crossover's at all? Why not run woofers, mids and tweeter with separate speaker leads to a EQ type thing to be a real "active" crossover?

Great series of vids love this

Not sure if I'm only speaking for myself, but there is a whole lot more I'd like to know about Crossovers. hint hint

Maximum respect for the guy who talks about crossover, but I'm not sure that 4th order crossover are the best choice because of its phase issues. The sound of the speaker is hugely dependent from the crossover topology. Troel Gravesen, who is a well know for his DIY projects, prefers LR2 topology. What do you think about it? Any experience?

Active speakers with an optimized amp per driver and cross-over filtering using DSP is the future of a highest performing digital audio system. It also allows for other tweaks towards much better tonal balance and phase optimization. It’s what makes the KEF LS50W sound better than the KEF LS50, for example.

The best drivers are cube audio 2.4 Tesla magnetic field saturation higher than any other speaker in existence it is a single drive and doesn't need a crossover you should get one Paul and try and out make a speaker out of one they can get it down to 27 Hz at a 3 db roll off with remarkable low distortion I think it is the best driver inexistence at the moment

There is no doubt that Chris knows what he's talking about but for a complex subject like fourth order crossovers I would like to see this information in writing so that I could digest all of this information it at my own pace.

Did you guys have the MELT for lunch?

The problem with a lot of full range drivers is that they have a mechanical crossover. One voice coil, two cones (often one wizzer) and a mechanical crossover. A true crossover-less full range has only one cone/diaphragm.

From my experience, a Crossover optimized for mediocre Drivers, makes for a "better" Speaker; than a Speaker with the Best Drivers, But were the "designer" ( probably through inexperience) doesn't understand the concepts stated in this episode.

Nice to see Chris again. Seems he's been on hiatus as of late 😟

Should have covered the fact that too many producers use cheap components in very expensive speakers..

Definitely not EVERYTHING I wanted to know, but I'm sure you'll do a cross-over with other engineers at some point. Hahaha.. damn I'm good!

I grew up listening to 8" full range Philips speakers, those which are still being produced by others. Skip to 4:45 to skip the unboxing here kzfaq.info/get/bejne/aauAdNxzq9a2hp8.html

what is the status of PS Audio's speaker line

Grandinote could be your next guess. They're using like 36 mid-range and around 12 tweeters for one column only. They keep using the simplest cross over for the tweeters, so to keep the speakers close to the full range philosophy. REMEMBER the axiom : no capacitor in the power line. See your discussion about capacitors quality.

Linear phase DSP crossovers is the way to go if you want the optimal sound quality.

What about a commercial crossover and 3 amps ..are they less susceptable to the distortion he aluded too?

BRING BACK THE ENVELOPE.

2:20 ... Did he say "four inch woofer"? I do not believe that "four inch" and "woofer" belong in the same sentence.

I enjoyed understanding nothing 😄

A long and laborious way to say (most drivers today are garbage and need a lot of crossovers to sound OK. OTHER than that, this video was ok, I just wish this guy was more likable.
