A sign that the A12pw does not get enuff love. I really like this driver (listening to the big MTMs with these and A7)

Here’s a little love, 12pw’s and a ribbon tweet, second order passive 8khz hi pass on ribbon...but we digress...

 

[toobhed]

I stand corrected, line level active 4th order hi and low pass at 2200hz

 

[planet10]

I was waiting for someone to do that :^)

What box are the A12pw in?

dave

 

[toobhed]

the bottom chamber only of the simple two way (no a7 top chamber), port vented per design...

Hi all,
Has anyone compared the A7MS to the A11MS, purely as a mid/high?

 

[planet10]

Not yet, but i have drivers, FHXL & FH3 to compare them FR. And A WAW i plan to try A7ms in.

as usual Dave is ahead of the curve, looking forward to your comparison comments

Great stuff Dave, I really look forward to hearing your thoughts.

Hi all,

is there a Sea Stack MLTL for Alpair 7ms? I would much appreciate it. Thank you

 

[Gerardveen]

Is there going to be a pluvia 11 HD??

 

[Scottmoose]

If there is, I wouldn't expect it for a good while, the Pluvia 11 is still quite a new driver. The 7HD uses most of the guts of the old 7.3 with some mods. and a new basket; the Pluvia 11 was a new size unit so already incorporated some of the design features of that older generation of Alpairs.

Looks like there is an A7ms “SeaStack), but it does not yet have a name or has Scott QCed it.

Yes and no. If you'll forgive the expression. I can do one, in fact I have the dimensions saved -it just needs drawing up. The reason I haven't published it is simply because it won't go much lower than, say, the compact Okapi MLTL I did for the 7MS, and has higher driver excursion (there's a limit to how much you can realistically squeeze out of a fairly small unit). If you want me to put it out, I will, I simply note that is the price and that in this case, I prefer the smaller enclosure.

Oops. the design i was looking at was the early SeaStack drawing.

OK - thanks for additional explanations of benefits of Okapi. My thinking was exactly to see if Sea Stack will go lower or not

If i may ask, below plans are similar in dimensions. In terms of performance - what is main difference (if any)?

Okapi 7MS

I'd forgotten that one. It's not quite as refined as Okapi (or the pensil) so those would be my pick of the MLTLs that I've done for the 7MS.

Thank you!

In my bedroom, speakers need to be close to the wall. I was wondering if vent on back (in Okapi) or vent on front (in compact MLTL) will be better if speakers need to be close to the wall? Thank you!
