Markaudio CHR70A Fullrange Driver

In this video I would like to feature the Markaudio CHR70A fullrange driver. This driver was sent to me by my customer. The drivers are relatively affordable at only $26 USD each.

Nice review, thanks. Not the same but I have the MarkAudio Alpair7 in an oversize ported cab in my apt where I cannot play loud at all. For the levels I can play I find them extremely enjoyable and musical. So for situations where it is not possible to play loud the tiny fullrange drivers from Mark Audio are great.

I wonder if they have a four incher. Off to their website I goooo!

I would guess that the 1.6kHz issues are attributable to a surround resonance.

Joseph, thanks for this video, lots of good info ...one question, the manufacturer recommends 100 hours of low volume music to loosen up the suspension, people say that this "smooths" the response of the speaker. This results are right out of the box or after the 100 hours?. Maybe if not is a good opportunity to make a comparison with the before and after measurements and that way we can see what it does, i hope you can consider, cheers

Nice one, used them yaaaers ago, pretty nice budget speaker, that also looks great. and well fullrange does have its charms. high SPL is not one of them :) but still enjoyable ! nivce review !!!

Can you compare Markaudio with Visaton B80 ?

[jericlee]

what is best speaker top 1 and top 2 for you?

Regarding the cymbals, could it be that you are hearing the aluminum material of the drivers and that was incompatible with reproducing brass cymbals? Also, that terrible breakup above 10 K can't help but change the sound of the cymbals. Sounds like a decent midrange that can be rolled off (steeply) to good tweeter (ribbon or amt?) At 5-6k. The small size can allow a very narrow front baffle and a small format tweeter could get close to coupling at the crossover. .

I was thinking of making a design similar to what you made and using the Mark audio replacing a need for a tweeter but what you said about the simbels has second guessing my idea. Do you think I will be better off just sticking with a tweeter?

Excellent review! Would you recommend this driver as a midrange driver in a 3 way?

[MrAlexandreazevedo]

Nice review. Do you think that these MarkAudio full-range speakers are adequate to be used as a single full-range driver in a speaker cabinet and combined with an external active subwoofer that can reproduce bass down to 20Hz? Would that 2.1 setup with MarkAudio full-range speakers be a better HIFI than using a 3-way normal speaker system with the subwoofer?

Thanks Joseph. What would you say are the technical characteristics needed for a speaker to reproduce accurate sounding cymbals?

[mkshffr]

I have the original version and they sound very nice though rather low efficiency.

Don't waste your time or money on these midrange drivers pretending to be "full range".. Expensive for the tiny Xmax. To get any bass a large vented resonant enclosure for horrible transient bass response or a huge long transmission line enclosure that will cost way more than just buying a nice larger Xmax coaxial driver and putting it in a nice smaller box. The high frequencies will come out in a narrow beam and the upper mids and highs will be punctuated by cone resonances and breakup modes. So simple jazz with a single voice, bass and drums will work fine. These are a total disaster trying to reproduce a choir or complex music or when you want to distinguish between instruments. These are vanity drivers built to look really nice for the DIY crowd, that can't design a crossover network. Not good performers. Adding a woofer and a tweeter and you will have a good speaker.
