Alpair MAOP 10.2

What is difference between MiniOnken for MAOP10 (Alpair 10.2) and Fat Classic GR miniOnken http://www.planet10-hifi.com/planset/fatCGR-extents.pdf

 

[planet10]

MAOP 10.2 is not Alpair 10.2.

The Mar-Kens Bob is doing and Leif first built, are the trapezoids (kudos to him for figuring out a flat-pak) which would have the same tuning as a CGR for the MAOP would be (no one has asked), but has a much lower diffraction signature. The tuning across different drivers is different.

The tuning across different drivers is different. Yes of course. But also consider that MAOP10 are with different parameter. My have fs=34, and Qts=0.28, not same like Leif or others, so it will not work with my driver. Tuning of minionken is probably around 53-56 Hz.

@planet10 the plans call for lining the internal panels with 1/2" wool felt. Madisound only has 1/4" wool felt, can I use it?
Do you know of a source for the 1/2" wool felt.
Also is it okay to use melamine foam instead of the wool felt?

 

[planet10]

Sure, use 2 layers. I have not searched out wool felt, there are many sources.

Turns out that parameters change in the right directions to keep the box tuning the same.

I wouldn't use foam of any kind.

I know X has recommended those scrubby eraser things. I have not tried it. It is not natural, i prefer natural products (in most cases — good polyfluff is not natural). I don’t use foam, and what i pull out of recycled boxes is usually used for packing.

As well even at the dolalr store ($1.25 store here) they are quite pricey.

I have used melamine foam for MAOP 10.2 (bookshelf) but only at the rear cabinet wall, to avoid back reflections from the driver. And then polyfluff on the other sides.

Works very well. No coloration, no resonance/reflections, no boominess heard.

The melamine foam in my experience works very well on certain applications (better than those egg crate foam types). I haven't tried using them for all wall sides though (might be too much of a good thing)

Hi, I'm trying to reach LeifB60, but to my surprise, my post still need to be moderated, and I am not yet allowed to pm anyone. This is very surprising to me, as I have been a member since early 2017. I've not made many posts, but still... Anyway, sorry for the offtopic post, just trying to get some posts under my belt. If you see this Leif, may I ask you to try to pm me?

 

[Mooly]

I've not made many posts, but still...

This is only your second post

If @LeifB60 sees this he can start a pm with you.

 

[Zleepy]

Well, yes, but would you not think that if I were a spammer or if my intentions were ill natured, I might not have had the patience to wait for 6 years before starting . Though I've apparently only made two (this is the third) public posts, I've had several private conversations with members before. The right to send pm:s apparently expire after a while?

 

[Mooly]

You would be surprised. We have these measures in place to protect the membership.

If someone starts a pm with you then you can reply to it in the same way as any standard user.

 

[Zleepy]

Ok, I will of course comply and I do appreciate the strict rules. Leif just sent me a pm, so I will continue from there. I'd really appreciate a "standard user" status though .

 

[LeifB60]

I have sent a PM.

@planet10 , do you have more Onken designs for the MAOP10 than minionken? Would a slightly larger onken cabinet yield lower bass response? I'm trying to decide the best cabinet for me for my recently acquired MAOP10 drivers. I do like the FHXL, but I'm pretty sure my wife doesnt . The minionken would sport very high WAF,but would have to be a compromise sacrificing bass response.

@planet10 Will MAOP11 a good contender for PAP configuration along with Eminence Alpha 15A?

 

[planet10]

People seem to like the M11, i have not heard it. Almost any good FR will make a good mifTweeter in an OB. But i would tend to look for somethign smaller.

The 15A is quite popular for OB as it is cheap and high Q. I have a pair, they are not very good IMO.

Zleepy,

Almost everything was reset when we switched forun software. Any member who had not posted within a specific time was sent back to new status. Done for security reasons.

I mostly only do miniOnkens, and usually the optimum size for that driver first. They only go as low as they go. If you want lower you need to go to a quarter-wave enclosure, such as Frugel-Horn XL or the appropriate Pensil.

I have not yet done any specific miniOnkens for the M11.

Ignoring that i have not yet explored enuff woofers, woofT stands that add bass extention are doable in most cases.
