Went with Reserve R700 for the better bass response. We did an A/B comparison with the L600 the R700 in the same room with the same Anthem receiver and the R700 had the bass punch that I could feel across the room in my chest. Bravo Polk Audio! They're both fantastic speakers, but since it was a larger room and I liked the bass response more, ultimately I landed on the R700, it will be one year in May. The best audio upgrade that I made in several years. We moved out restored Eosone dipoles, also made by Polk in the 90'e to another room. The L600 needs a subwoofer to sound amazing. The R700 you could definitely get away with no powered subwoofer. 🤷‍♂️

Teaching to these key principles then drives true UNDERSTANDING for your viewers.

The laboratory portions of Chemistry, biology and anatomy classes are essential to students getting a grasp on the material. A lot of the technological advances that have improved the quality of life in this world came about because of experimentation done at institutes of higher learning. Teaching the basic concepts of what is already known and accepted at any given time would not have brought about advances. That SNL skit about "Theodoric of York, medieval Barber" comes to mind as an example of where we might still be.

[@staceymangham]

Great review as usual and appears to be one of the best speakers you have evaluated so far. I have to question a statement i have heard you make on several occasions that Bi amping isn't really worth it and makes an insignificant difference, i have had. excellent gains Bi amping using one 2 channel amp to drive the lows and another 2 channel amp to drive the nid/highs, the woofers are controlled far more superiorly and stop and start much better, and the hghs cleaner and clearer with gains across the board. Also it allows you to use stranded cable for lows, and solid core for highs The other way of implementing this is using one stereo amp for left lows and highs and another stereo amp for the right lows and highs, with the ability to gain increased stereo seperation, but i believe less affective, as both amplifiers power supply's still sees lows and highs but just doubles the power

Re: 5:30, bi/triamping only really makes sense with active crossovers because of the associated benefits of actives (only wire between driver and amp, ability to use better matched amp power per way, etc etc). There's not much point to doing it with passives. Better to get an amp that can drive it full range. Crossing with a sub isn't a bad idea either.

[@raidendigital1003]

Bi-Amp on a speaker is useful to me because it allows me to use 1 Dayton DTA-1 amp per speaker. I can have twice the power in places without access to a wall outlets for power. (The amp uses 8 AA batteries each.)

You don't get twice the power when you do a vertical biamp. Its still the same amp putting out the same amount of power. Having the amp power one speaker instead of two definitely makes the amps job easier, but its nowhere near double the power. A vertical biamp is done to improve sound quality, more than to get extra power.

Interesting video - this manufacturer managed to make money and not destroy the product's quality in the process. Polk sucked for years, but their various speakers have gotten very good reviews for their price points as of late. Something obviously happened at Polk, they are selling much better product these days and that is wonderful to see. Polk is a mass market company that has to build product to a budget as Danny pointed out, but for mass market "plug and play" speakers Polk is very competitive. Danny's advantage is there is no middleman and the customer supplies the labor to assemble the final product. In return, the customer gets high quality parts that they wouldn't receive from the mass market companies.

Hey Danny, I've been using your crossover upgrades in my RS750 and RSC200 speakers for home theater for something like 15 years and I disagree a bit that home theater doesn't benefit much from the upgrade. I love having clean and non fatiguing sounding speakers for home theater, and as someone who spends as much time watching movies or TV as I do listening to music, I wouldn't want to be without these crossover upgrades. Your crossover upgrades are one of my favorite purchases ever made, often in the context of home theater. Some movies and TV shows also have brilliant scores that are just as good as some music albums, things like The Fall or The Knick come to mind that have really blown me away.

You're right, all of that makes a difference. I should not have trivialized their use to being okay for home theater, because they could be used in that application without much complaint.

Have you tested the R700 from Polk.? I would love to hear your take on them

[@mitchdowning8188]

The dolby atmos capability of these Polk speakers is one of its design features that seems to fly in the face of conventional stereo sound and the "standard" frequency response testing which your graphs display. Loudness compensation in amplification (RE: Fletcher- Munson curves) is also one of the most misunderstood concepts in sound reproduction. The fact that sounds at different frequencies are "heard" by humans in different ways (e.g. - humans ears are said to be most sensitive to sounds in the 2K-5K hertz range) are due to natural adaptations of a species where directional information is important to hunting and self preservation in the wild (among other things) . There is a lot more going on with our perceptions of sound than can be addressed by getting a loudspeaker to reproduce a 20-20kz signal on axis in a linear fashion. That is certainly not the best way to reproduce the a sound that was PROPAGATED (spread) into the space in the original venue where it was produced. The reason why dipole speakers sound more "live" to some listeners has to do with the spread and reflections of sound in the listening room which somewhat simulate the dispersion of sound in the original listening space. The use of horn midrange in the relative role of the atmos speaker properly integrated into the design of a stereo speaker will drastically improve the "live" sound performance. However testing procedures must be adapted to room rather than on axis response criteria.

[@rapfreak7797]

But every room is different. At least frequency response gives a more universal comparable starting point.

[@mitchdowning8188]

@@rapfreak7797 Right you are. Every listening room is different and the only way you can approximate the original sound field in MOST rooms is by using the recorded signal that has been supplied and dispersing it into the new listening room in a way that simulates the space where the microphone took the sample. This sample must be multiplied and spread into the listening room as a sound field and at the same volume that occurred in the space where it was produced. Is any of this information available or can it be practically applied. NO - its is not available. As a matter of fact most recordings are composed of multiple sources recorded in different environments (rooms, booths, etc.) by microphones of differing types, and then often adjusted and mixed to achieve the desired "musical" result. Stereo is based on two ears and provides a pseudo-reality of the original sound, but as anyone who has listened to music performed at live venues can attest, it is not nearly the same. Should audiophiles continue to refine the same designs in the same fashion. Have they seen that it is at a dead end yet? Is it time for a new approach to attain HIGHER fidelity?

[@mitchdowning8188]

@@AZ-rv8wp While there may be an "average" ability for humans to hear certain frequencies of sound, there are wide variations in hearing abilities of individuals at any given frequency, Sound levels that listeners find pleasing in a listening room are also an important factor to consider. Some of the older Yamaha receivers had a variable loudness control that was useful in that regard . I completely agree that designing a speaker with a response that has equal output at all audible frequencies should be a goal; however, it should provide that output dispersed over a larger area to "saturate" the listening room with sound to better simulate the "typical" venue in which the sound would have been made (as if it were recorded live). So having a speaker that responds in a linear fashion in terms of frequency on axis (and beamed towards one sweet spot in the listening room), and having a speaker that actually "couples" the sound into whatever listening room it is placed, (taking into account the innate " tendencies" of human hearing in regard to frequency and volume) are two vastly different goals. I contend that the latter is where audiophiles must aim if they intend to find a more true to life listening experience.

I was going to upgrade mine but with the number of parts (7 resistors and 10 caps just on the mid/highs X 2)plus the very high values, it gets super expensive, very quickly.

No “allegiance” to Polk, but Polk did exactly the right things based on what see from what you shared in this video. They did exactly what they should’ve done because to turn this $3500 pair of floor standers into a $5500 pair, the average consumer of this product would probably not perceive a sonic achievement worthy of a 50% increase in cost, and may just find favor in another $3500 pair of speakers. Kudos to Polk for knowing where to draw the line commercially.

Hi Danny, What is the cost of your upgrade on the L600? And I’m wondering about the L800’s? I have a pair of each I use for atmos music

This was one i wanted to see. I saw some good reviews on them and Jay liked them he said they moved some air but they aren't audiophile level. But at least they put effort into it.

[@aronwhitesell9427]

I've owned the L600s for several months now, and they continue to surprise me at how good they sound. I upgraded from B&W CM10's, and the Polks are far better sounding, more musical and great audiophile speakers. Using a Anthem STR integrated amp at 400watts per channel.

[@BostonMike68]

@@aronwhitesell9427 nice I never heard them I'm just going off a review but I like them I like what I have seen in reviews. I would like to own a pair if I didn't already have room of storage full of speakers.

[@stevenbullock9276]

Boy, I hate the audiophile term. I have a pair of these, and from someone who’s owned many speakers (Nautilus 802 and Martin Logan Prodigy, to name a couple) these sound really good for the money.

[@BostonMike68]

@@stevenbullock9276 I think it's an elites term. I wonder how much they really hear in different systems up to a certain price point they look at it like the more you spend the better it should sound.

What's the difference between 'clarity', 'resolution', and 'detail'???

[@hoth2112]

They are 3 things that are tied together. Think of your speakers as a Television. The better the quality of the drivers and components within them are, the more it is like having a high-resolution TV, which means you will be able to see more detail, given that you are providing it an equally high-quality signal. (If you only watch VHS videos you won't benefit from a 4K TV) "Detail" is the ability of your speaker (or TV) to actually reveal small, subtle details within the music or video signal it is being given. (You won't benefit from a 4K Blu-Ray signal if you only have a 720p TV) and "clarity" is the focus or precision of those fine details within the soundstage. The lower the "resolution" or the lower the "detail" the less "clarity" there is and the harder it will be to pinpoint the fine details.

[@garylethbridge6220]

Great review. I just bought the polk r700 . Have you made an upgrade for that? Thanks

[@hoth2112]

We've not yet looked at that model. One would need to be sent to us.

[@mcplutt]

We are all waiting for that to happen 😄

[@walterdockins8475]

Someone before you posted that the R700 has 7 resistors and 10 caps just on the mid/highs X 2) of very high values. It would be expensive to upgrade. Maybe return your R700 and go for the L600 when they go on sale.

[@mcplutt]

@@walterdockins8475 Or maybe just wait for the verdict 😃

[@InPursuitOfLiberty]

The consumer is never happy. On the one hand people will complain about a lousy speaker, but when a speaker of the likes of Wharfedale is manufactured in China to cut down costs, they'll complain about that too.

[@dextermorgan1]

I almost bought these. I ended up with Revel F 206's instead. To me, they just sounded better though I know the internals are probably a little more "cheesy".

[@walterdockins8475]

Yes, Revel has a different sound... at least their higher end. I found the soundstage much much larger and less forward than some comparative speakers. It really comes down to personal taste at the point. Nevertheless, The F206 have cheaper parts and would benefit from just changing out the parts with better quality. So, you have an upgrade path if you choose to do so at some point.

[@dextermorgan1]

@@walterdockins8475 I'd love to upgrade them but I'm about as useful as two left shoes when it comes to things like that. Hopefully, I can find someone that can help me(or do it for me) and I can just pay them for their services.

[@canuckchris5733]

So back in the day the margins for profit in stereo systems started shrinking mostly in the electronics and turntables Speaker manufactures recognized this and started making speakers for retailers to increase the profit margins One Canadian company in Toronto made many different branded speakers in the same factory such as Mirage Paisley I think Sound Dynamics and several other brands I think that larger profit margin in speakers still exists today

I can't say. I have not worked on that one.

@@dannyrichie9743 is there anything I can improve like wires or something else that you can assume would improve the sound?

You can upgrade the tweeter’s capacitor with same uFarads as the original with a film capacitor. you can also buy no Rez from gr research to solidify your cabinet.

Great Job Danny for showing and educating us on the differences between quality and inferior parts, for example Air Core and Iron Core Inductors using any parts that have iron in the signal path that degrades the signal path based on stored energy with proven analytical Data.

Very unlikely unless the drivers and layout are identical. We would need to have one sent in to know for certain.

[@Dreez76]

I believe that if you're playing so loud that your 6" woofer's are maxing out their excursion... you're really playing too loud for comfort. I got a Yamaha A-S1100 so i can see when i'm playing 1 Watt RMS, and i've never played louder than 1 watt.. because that's loud, and my 6" woofers are barely moving.

[@07wrxtr1]

Based on the math - I can only imagine how cheap the internals are on my adam audio t5v’s… 🤣🤣🤣 I am guessing that on powered speakers they try to dsp their way out of cheap parts?

[@matthewtaylor7355]

20 parts in the tweeter crossover.. Why?? Roll the tweeter off with a single cap and hardwire the woofer speaker input.. They may sound better than recapping etc

[@hoth2112]

That board with all the parts contains both the tweeter AND mid circuits, not just the tweeter alone.

[@dannyrichie9743]

I doubt those drivers would respond well to a first order filter.

[@minus3dbintheteens60]

That small mid ain't gonna take much voltage full range. Half the crossover board is for the mid alone, requiring 2 seperate crossovers, high and low. And that ring radiator just the same as the mid won't barely take any voltage with a 6dB hpf. And the shallower the slope the more phase interference is an issue over a wider range.

[@markphilpot8734]

You can’t argue with the fact that parts quality is an issue. There is no substitute for high end components whether it is a speaker or elsewhere in the audio chain. Products are built to a price point so it only figures that the quality of the parts used will be reflected as to that decision making. There is no place in any part of the audio chain for mediocrity. You only get out of a system what you are willing to put into it.

[@ReferenceFidelityComponents]

I’d take issue with ghe statement “EI inductors are really bad”. They’re not. Properly rated above actual duty point they have many advantages including no or low saturation, zero hysteresis and ultra low dcr = great damping factor. That’s exactly what you need on a woofer. I use 6A rated silicon steel laminated cored inductors on bass duties which are rated to take way more than duty current and voltage loads. The testing has shown them remarkably low in distortion as a result. Way better than using standard duty ferrite or permite cored inductors which can saturate and have high distortion.

[@dannyrichie9743]

Yeah, but these are not in the woofer circuit. They are used on the mid. So an air core would be a much better choice.

[@ReferenceFidelityComponents]

@@dannyrichie9743 good point. Hadn’t realised they were in mids. Should still be fine though if rated high enough👍
