Okay so that’s what I’m talking about. Are there posts about these differences? Leaving aside the OB discussion (it would be my first choice, if only circumstances allowed), and ONLY talking about MTM varieties of the X boxed speakers, how does adding a port change the characteristics of these speakers?
My own knowledge on the subject is probably filled with misinformation. I know believe that generally, adding a port extends the rolloff point slightly but also creates a sharper slope. I also believe that there’s a complicated relationship between cabinet size, tuning frequency, efficiency, and responsiveness.
What I don’t know is how an X-MTM monitor differs from an X-MTM Tower(both either ported or sealed). Is it only a lower rolloff, ie more bass extension? Is there an efficiency difference? You’re essentially adding volume to the cabinet; what does this do?
There probably are, but they're also probably quite old, esp since the X-SC is not current even on the website, but should be once Danny has the new website up & running.
As for the port, you pretty much explained it how i also understand it, a little better extension but with steeper roll-off.
The X-SLS Tower is able to reach down into the 50s in most cases, while the standard X-LS usually plays into the 70s before a subwoofer is needed depending on your setup. In my bedroom room, I can get to roughly 80Hz reliably, where my subwoofer takes over.
And in the case of the MTM versions, having dual woofers playing in parallel, allows them to do the same amount of work with half the effort, and should allow for a little better extension as well on the low end, but isn't too far off of the standard.
I person cant speak to overall effeciency, but having dual 16ohm woofers playing in parallel acts the same as a single 8ohm woofer, but each driver is only working half as hard, allowing for a faster, cleaner response, but
Or speaking only of the port: if you add a port without changing box volume, what does that do to max output at different frequency levels? And lastly, would there be any difference in the crossovers of an X-MTM, whether it uses a port or not, or depending on whether it’s a monitor vs. tower?
I'm also not certain about the difference beyond what we both
already understand when it comes to ports.
Far as i know, the crossover on the MTM models should still be the same as their standard counterparts since the crossover point is determined by the relationship of the tweeter to the woofer which remains the same across all models. Even looking at the NX-Studio crossover.
Iirc, the tweeter used in the X series usually plays down to 1000Hz where the woofer takes over down to 70-ish Hz, so the only differences really exist within the 3-way designs like the X-Statik and X-Voce.
