Markaudio CHP-70 Gen2 Natural Paper

http://www.madisoundspeakerstore.com...natural-paper/

Was wondering if anyone has used any Mark Audio drivers before? I like there specs. There cast frames are built nice. There 4" driver frame is amost a 5" driver. They state that they can play down to 40 hz which is good for a 4" full range. I've been looking at these drivers for years and I think Im going to get a pair of these. I love tb drivers and "some" fostex drivers. But Markaudio seems like they got some neat drivers.

Was just wondering? Thanks for your thoughts

Re: Markaudio CHP-70 Gen2 Natural Paper

I've recently built a pair using the CHR-70 drivers. I really like how they sound as is. I bet an experienced tinkerer could make them sound even better.

The upper range is very clear and pleasing to listen to and they do reach pretty low. Keep in mind that even though they have impressive specs and do "go low" they are still not really "woofers." They are full range drivers and, IMO, should be coupled either with a subwoofer or an additional driver for lower frequencies. That said, for a small room, office or computer monitor they would work fine by themselves.

One thing I have seen mentioned is that the larger full range drivers tend to not perform as well off axis. Well, that may be true but everywhere I have listened to mine they sound great given what they are - a single driver dropped into a cabinet.

The frames are resin, not cast as in aluminum. They have a very high tech design. Lots of designs on Diyaudio forum. Alpair 7 and CHR70 third generation (aka CHR-70.3) very popular. The CSS EL70, ERT26 and EL166 are also made by Mark Audio. The EL70 is very popular as well. Ryanbouma has posted a build. Dr. Griffin and Bob Brines have also done builds. I have some in the works.

Here's an EL70 model in 13.8 liters net. Based on average measured specs from 4 drivers, partially broken in. F3/F10 42/37 vented, tuned to 48.

Hi Bart, Mark's drivers are not well known here. But there is a huge community of users and designs elsewhere.

As for the CHP, it was designed, like all of his drivers, based on diy'er feedback. Some people wanted a 'vintage' sound. If this is not what you are after chances are you want the CHR70.3 instead, which is *outstanding*.

Once you listen his drivers, it's hard to go back to a 2-way - and I've built my share. As Dan said depending on your listening habits you may want to cross to a sub/woofer. Common sense applies, if you're looking to bring the house down you'll need something larger.

A pair of nice sounding full range speakers in a 2.1 or 2.2 is just amazing in sound. Ive noticed in my pair of 15" AN NEO'S have an off axis that is terrible. But in a big room(14.5' x 25') centered 7 ft or beyond and back sound very nice.

But, these smaller drivers sound really crisp and just stellar with a great off axis. My desk is of the left of my 2.0 office setup. You actually dont really want to stand in front of them long. The Wallie's W5-1880 will push you out of the room.

One thing I did with a 2.1 dayton plate amp is hook them up to a pair of FE126en in a pair of BK-12 folded horns. For the sub I had a cheap but awesome 8" dvc subwoofer. The plate amp has a high pass filter of 150 hz. Which makes the satillite speaker(fostex) just scream with no bass. As the sub plays its specturm of sound. 50 watts to the sub isnt much but this sub paired with a 2" pericsion port tured around 30 hz is just clean deep bass that completes the full range.

One other thing Ived noticed is that in a 2.1. I found that the sensitivity is nice when you match the sensitivity with full range speakers and with the subwoofer sensitivity. That way you dont got the sub cracked and the sat's turned down. Matching the subwoofer output level and sat level sounds really good. Its not a bad thing but Ive noticed it just sounds nice and everything sounds more balanaced while using this plate amp.

I have to say it just blow my mind away on how clean a class d amp sounds. Without the FR's play anything under 150 hz the fr works so much easier due to not producing any bass. I dont know if Im the only one that feels this way?

Re: Markaudio CHP-70 Gen2 Natural Paper

A lot of people cross their smaller FRs low to a woofer or sub. I have Alpair 7s in smalled sealed cabs that allow me to cross to RS225s at the ~150hz. Planet10 is a fan of using passive line level crossovers for 200-300hz range with smaller drivers.

Re: Markaudio CHP-70 Gen2 Natural Paper

I'm intrigued by small, full-range drivers in a 2.1 application.

Re: Markaudio CHP-70 Gen2 Natural Paper

Those CHP70s look really nice. I never looked too deeply into markaudio drivers because they were always out of my price range, but these are much more affordable.
Wheres different between these and the $56 version?
I wish madisound had free shipping though.

Just to make it clear: There's the CHP paper driver, and the CHR metal driver. Both are $36. The only $56 driver are the Alpair 6P(paper) and 6M (metal). They are 3", not 4" like the CHP/R. The Alpairs are more advanced design. The description on madisound are fairly thorough as far comparing differences.

Re: Markaudio CHP-70 Gen2 Natural Paper

I've been lusting after those CHP-70's since they arrived, although I don't know WHY. I'm fond of good smaller paper coned drivers too. The good ones sound so effortless to me, at reasonable volumes. At half-price, I'd be all-over these. I'm sure they're worth the price, but I have tweeters and XO componets to buy for three projects right now...:o

Re: Markaudio CHP-70 Gen2 Natural Paper

There seems to be mixed reviews of the new CHP. I haven't heard them yet, was supposed to have.

I'm surprised how many people like the CHR. I guess I'm alone in not liking it very much.

Re: Markaudio CHP-70 Gen2 Natural Paper

I've built a sound bar and used a pair of aura 3" full range. With a 8" sub. The 3" drivers sound amazing, but just not enough(size) to keep out with the sub. I Should of went with a 6.5" subwoofer. I was wanting to put a pair or these in 4" markaudio instead of a 3" FRs. The Markaudio Full range play to 25,000hz which is amazing. I think a paper cone sounds just as good if not better then a metal cone. One thing that I love about the mark audio speakers is that therer qts is alittle higher. Which makes a bass reflex and a sealed design not to hard for anyone to build. Dont get me wrong Im a big fan of lower qts drivers which is good for tl or different horn designs.

$36.00 dollars seems doable. Ive been comparing tb to mark audio. Though both companys are really good. Its hard to decide but I think A pair of these Mark audio will be bought today for sure.

Ryan, may I ask what it is you don't like about it? Also, do you not like it compared to other drivers in its price range or do you not like it period? I'm just curious. Thank!

What do you guys think of this kit ?

Re: Markaudio CHP-70 Gen2 Natural Paper

While the cab is designed by a reputable designer, the price seems awfully high when there are other designs that will be as nice with several other drivers.

CSS EL70, MA Alpair 7, Fostex FF85WK, Fostex FF125WK, MA CHR70.3

What do you guys think of this kit ?
