Markaudio Pluvia 7 vs Markaudio Alpair 7MS. A subjective and objective comparison.

Is there any chance you can get this away from your walls? Outside maybe?

I chose a linear Sin Wave Sweep ...

Please use 1/12 octave averaging. As they are now, graphs are almost unreadable.

@Dr1v3n, Glad they are sounding good.
What is the grand plan with the array?
Are you going to switch to all 7ms array?

Have you seen there is talk of a group buy for the new (not yet released) square basket Alpair 5.3, I don't think it will have the new cone design, but the group buy was for a square basket suitable for line-arraying. Darn sight cheaper per unit that the new ms series.

Its a 4” driver. The 7 standa for 7 cm cone.

You're correct, I don't know why Madisound puts it in their 5" FR driver section and the P7 is in 4". That's probably what I was thinking of.

We have alot of songbirds outside. Just take the graphs as an approximation?

Will do. I redid the 7MS measurements today and finished the P7 measurements as well. Will upload soon.

Definitely switching to the 7MS. I have to pay off 1 credit card, close it down and open up a new one with a 12 month no interest.

I like how the A5.3's sound, I have 8 of them I have to wire up for a rear channel. That's another project somewhere on DIYAudio... But, it's easy to switch to the 7MS from the P7 as the mounting pattern is identical.

Here's a replot of the 7MS FR using 1/12 octave.

 

[Dr1v3n]

Here are the P7 plots.

Time to put the arrays back together....

 

[Dr1v3n]

BTW those tests were done with no EQ, linear sweep was from 100Hz - 20kHz... The 7MS's are back in their box. Waiting... I took this time to put the 1 actively powered/EQ'd sub in the SPDIF loop. Also, double checked every enclosure for proper wiring polarity and fiberglass stuffing. This was a little tangent of a project, measuring the 7MS's, and it was well worth the time.

... for the new (not yet released) square basket Alpair 5.3...

Wasn’t that a CHN50?

A5.3. AFAIK they have only hit the market in Japan. Sure you don’t have A5.2?

Woops, you're correct Dave. I have the A5.2's. Sorry about that.

Question: why are you capturing from REW's RTA instead of using the built-in measurement system?

The latter produces a swept sine tone, and spits out frequency response, phase, distortion, and a bunch of other useful (derived) stuff like waterfalls, impulse, group delay curves, etc etc.

I would if I knew how. I'm not very experienced with REW yet.
