Just use two subwoofers under the fullrange drivers and you are all set. That way you can use any crossover point, even higher (300Hz), as long as sub will perform that high. Fullrange will be happy.Hi there,
Currently I have an OpenBaffle system in WAW arangement with DSP corrected frequency response.
The used driver is an Alpair 5.3, crossed actively at 200Hz, and a KEF sub is working downsters.
I am really satisfied with the sound this system produces: Very clean sounds and good imaging, really good dynamics... The singer highly seems to be in the room.
My only problem is, that the 200Hz crossover frequency is a bit too high for the sub and too low for these drivers. It would be much better to lower the frequency to 150Hz, or further below.
My question is:
Which MarkAudio driver would be the best choice to replace the current one? Paper or alu cone?

I have made the new speakers. They are working fine since mid of September. I was very delighted with their performance.
Since a few weeks or months, I hear something strange... I mean, everything is perfect (sound stage, air, clarity, dynamics), but I feel after a (half) hour long listening, that the sound is boring or annoying somehow. Just don't want to listen more. Maybe this is the alu driver's effect (MarkAudio alpair 5.3).
What do you think about this experience? Haven't you felt any similar with alpair drivers?

If this regards the sound of the Katana 1.
It is a small baffle and the center to center spacing with the wideband is large.
Not knowing their crossover design. The implementation would be likely to have a lot of vertical issues and overall response issues.
I dont think it is a driver issue. It is more a baffle/design and crossover issue.
With the speakers low to the ground and listening up high. Looks like a Vertical response cancellation Dipole nightmare to me.
Could likely be saved reusing the same drivers with a different baffle and crossover design.
Thanks to modern software it would save a lot of time as opposed to the wild guessing method.
Looking at their baffle and driver mounting positions. Wild guessing is the method.

I have not heard this combination but I suspect that 11MS drivers in a wide open baffle with the Pass FullRange EQ (before or after your preamp, if you use one, or between your source and power amp if not) would be very promising. I am using such a setup (more complicated) with 11MS drivers in small Nostromo cabs and it's fabulous. I have dialed down the EQ in my setup, but the base settings in your OB might be just about right.

If you've recently changed digital front-end that might be a factor. Integration with subwoofer, large phase difference will sound "hollow" half-empty unless your sub has continuous phase knob dialed-in. The Alpair 5 driver is quite smooth and flat but still has a residual metal sheen -- you might look for the MAOP 5 to upgrade or perhaps try dave's gloss coat miracle tweak (I'd do one cone-only and one dustcap-only and compare).Since a few weeks or months, I hear something strange...

As mentioned in another thread I'm doing a cheaper driver before the Mark Audio Alpair 10.3, namely Michael Audio 4" AlMg cone (same cone size as MAOP 7), kind of an experimental edition of the "drum paper" 4.5-5.5" drivers I often praised. So I applied one coat of half-strength MicroScale Gloss to one driver (call it R) and couldn't even see a difference -- I thought both drivers must have been pre-coated already, the way the diluted liquid ran and pooled over the cone. Aack so much for "as little as possible"! I soaked up any excess, pooled, over-ran Gloss and waited 24 hours. First...
