GR Research LGK 2.0 Kit Speaker Review (video)

[DSJR]

Even with my bad lugs, I could hear it from the get go using 'phones. Reminds me of either the Daleks' ring modulator or a very badly worn saphire stylus from my 'portable record player' childhood...

I'm sure in bits of video's I scanned, Dan was mentioning an ~80Hz high-pass. Not sure if this could be achieved by shoving a large value cap in series on the input (I think some lower cost smaller conventional big-name UK made speakers did this some decades back)?

This speaker sounds very comparable to my Tivoli Model One Radio
the size of the driver is also not very different.

I’d love to see how Danny talks his way out of this one…

Thats only possible if it has tube connectors, and highend caps and induktors.

Hehe, this system doesn’t use such highly sophisticated parts, but in addition, the tivoli is equipped with a huge bass reflex port in downfire configuration. ;-)

If a speaker falls apart with this, I dread to think about how it would handle some classic synthpop.

Is this song title chosen just to mock the speaker?

ASR readers like graphs of measurements? Here some of my measurements of Tivoli One, Tivoli PAL and Sangean WR-2. Measured set on a kitchen stool, 1m distance

Amir, thanks for this enjoyable video. But to really appreciate this little giant killer you have to run this track:

I went hearing that video with utmost interest.
Now, if you please, where could that bass have got to ? Into the future ?
To my ears, it lacks any interest regarding bass notes. Tap a table and you will hear much more bass. Avoid the corners for deepest results..

Have a try listening to those astounding drums thanks to Buchardt A700...

That sound demo, wow, not even smartphone speakers fall apart that badly.

You're right this track has modest bass, but it's deep and continuous. I've been using BASS 305 tracks (from CD) in the past mainly for fun and to see where the limit of a specific system is. There are some other tracks from them which show any incapability of power/distortion/crackling or resonance issues. I guess mainly because the bass notes are pure, long and sometimes very low (can only feel/see them). Every bass deficency jumps right into your face, especially with headphones. I've catched quite a few bad ones with this kind of music.

Ok, sinewave could do that too but with less fun.

I used to have a model 1 for kitchen duties, excellent radio and very pleasing sound.

So this is his response...
Now you need a Sub of course, and you should only use it in this 'intended application'
I assume he hasn't ever mentioned that before.

 

[DMill]

@amirm Definitely one of may favorite reviews so far. This speaker clearly falls outside of a speaker with colorations that someone might prefer to a broken design.

 

[orange_juice]

I just watched Danny's video now and it seems that he acknowledge what it was found in Amir's review (distorsion and bottoming out in low frequencies) and he's experimenting with adding a larger driver (5") just for the low-range part and handover to that 3" driver as soon as possible.

That should help a lot with the distorsion and improve bass response.
Maybe he should have set these expectation from the beginning but I think ASR's review provided a lot of insight for potential customers into the limitations of this speaker as it is today.

Sure the upgrades will be very cheap.

 

[orange_juice]

The cost itself would be indeed important in evaluating ROI.
From what he said, those 5" woofers are "stupid cheap" and it would be interesting to see if it would be something within the range of $20-30 for adding that woofer. (maybe changing those parts from filter to crossover might add some extra cost if more parts would be needed).

well that's better than never, but back to square 1, how can it be the giant killer by itself then?

How should this happpen? For the older costumers no way.

Adding a woofer is a new speaker.
