I got news from the pensil enclosure designer that they in the process of drawing up a dual driver configuration for the chr70.3. I would strongly suggest to follow properly designed enclosures. Please take time to read at diyaudio forums and check out the MA enclosures at frugal-phile.com. If you follow their designs you will be able to optimize the driver performance as intended by Mark Audio.

may nagpaparating ba ng MA dito? Feasible din ba yung similar config as JoeyGS but will instead use Alpair 10M Gold and Alpair 12P? or better kung parehong 10M?

Meron akong na-encounter before na box design with dual Alpair 10.2 (not the new 10.3), the twin mar-ken10.2. di ko sure kung pwede sa 10.3.

ang ganda nito if it will be well executed, may be difficult to DIY for a newbie pero for sure kayang kaya ng mga masters...*cough* timber! *cough*

experiment lang.
meron na kasi ako AN FR na single driver. try ko naman dual driver. Or pwede din kaya passive radiator yung isa? pag di maganda result, balik na lang sa single driver design.

You can pm Scott at diyaudio to confirm Alpair 10.3 into an Alpair 10.2 box.

Hear is one thread that Scott provided an advise:

1st stage sanding na ulit.

Next week glaze muna yung mga imperfections pa rin....

Ganda ng design Deist, fully braced pa!

Bakit kaya gising pa si joeygs?

Oo, sinubukan ko kasi yung mas makapal na wires eh though dati na ko naka van damme. Were so happy, I just might order a spool.... Hehehehe

After a month my enclosures are done & have been gathering dust in my office for a couple of weeks until I was able to find time to put it together last weekend. I've been busy with work lately & my family did some volunteer work in Villamor the past 2 weekends for the victims of Yolanda.

I inquired from known enclosure fabricators here in the forum but due to sked conflict & time constraint I just decided to ask my suking karpintero to build them for me. He doesn't have any experience fabricating speaker boxes so it took us more than a few back & forth discussions...ganun pala talaga kapag parehong first time

So after some issues with plywood finishing, sizes of wood available around etc. I decided to go the engineered solid wood route. The finish is still rough, we just applied varnish and that's it. Ipaayos ko na lang finishing pag may time na. Below is the built pic:

These are Mark Audio Alpair 10P Gen 1 drivers on Pensil enclosures. How does it sound?...Well, I promised myself to be objective about giving my listening impressions & not let my excitement get in the way.

I've only been in the audio hobby for 2 years now, I don't have many gear as I like it simple & don't want to spend a fortune on this hobby, my priorities with family outweigh any hobby but I like to think I know a good sounding audio setup when I hear one.

My objective for this build is to produce a pair of speakers with very good to excellent midrange as I find myself listening to a lot of jazz, acoustic, neo-classical/classical music lately (ganun yata talaga ang tumatanda ) It is also the reason why I chose the paper cone drivers. I opted for the pensils because they are front firing & doesn't require much space from the wall, they will be put in a smallish 16sq/m room. Let me tell you these drivers doesn't disappoint and something tells me they will sound better after a couple of hundred hours.

I'm still listening at low to moderate levels per recommendation of the manufacturer and I can already tell that these are smooth sounding speakers with a lot of detail. I also noticed that there isn't much difference or no difference at all when listening on axis vs. off-axis(20-30degrees). Listening late at night when everything is quiet made me hear details in songs I never knew were there before. I've been listening to speakers with tweeters as far as I can remember but I'm not missing them on these pair. The low end is still inconclusive at this point since it is not recommended to listen to heavy bass sounding music until the burn in period is done but I can hear coherent low end on jazz materials. Piano, in my observation is what most speakers I've heard are having problems in terms of producing natural sound and in these speakers I'm hearing the most natural sounding piano timbre on my system.

So are these the best sounding speakers I've heard?
NO. go to a hi-fi show & you will hear better sound but the price difference is heaven & earth. And these speakers can give them a run for their money

Are these the best sounding speakers I have owned?
YES, as mentioned I don't own many but these are the best sounding speakers I can afford or willing to spend on.

Would I recommend this to others?
YES, but it's not for everyone.

I am loving the DIY route, the first time I hooked them up was like the when the bulb started glowing up in my first science project when they made us light a bulb using batteries in parallel/series circuit Now, on to my next DIY project...a tube amp, will probably get a kit for newbies like me and hopefully I won't blow our house to dust

Another pic:

How thick is the engineered wood from Pateco, is it the one they sell as 1" but actually is less than 3/4"? Thanks.

deist · « **Reply #435 on:** Mar 18, 2014 at 05:31 PM »

Yes, that's it. The one they say for counter top. Thickness is 19mm.

Thanks, I have been buying that finger jointed wood from them for my shelving and drawer projects, but I don't think they make it wider than 12".

Have you noticed any resonance? Did you brace your speaker cabinets?

I notice some resonance when playing in loud volume, no bracing yet I'm thinking if I need them as the box designer says it is optional. Will experiment lining the walls with some wool felt, hopefully will make the enclosures dead silent, wala lang akong mahanap na wool felt or equivalent locally.

I've been reading about enclosure resonance, why some speaker manufacturers use thin walls with some resonance, apparently it adds "warmth" or "brilliance" to the sound, it adds color. While resonant free enclosures are more transparent. A matter of preference.

Try using materials similar to "Dynamat" to deaden the walls but you still need to provide the polyfill lining to eliminate or control the wall reflections. But compute first the cost of the "dynamat" as compared with adding bracing.

Inunahan ko na brader. Checked and lightly sanded the enclosures and it seems we just escaped the curse of the jojo

Bukas I first need to find a clean space to spray the final coat, sayang lang kasi kung magiging airport ng insects....

Btw, punta ka sa thread ko, may group buy kami na powertool na sigurong magugustuhan ninyo ni jojo
