Right, my curve example was just to show what the control points look like in RB. If you load up a file with no custom curve edits, there will be no control points in RB listed. I'm pretty happy with the results of Audyssey without having to add a lot of edits, so in my case, just lowering a broad range did the trick for me.

Since the app and RB cannot be used exactly like a PEQ, you will need to use probably 3 control points per adjustment for narrow adjustments. Ie. there is no "Q" to let you tell it how wide you want the change to be, so use 1 control point below and one above the frequency you're trying to change with the middle control point being the actual adjustment.

Something like:
#1 200Hz 0dB
#2 300Hz +3dB
#3 400Hz 0dB

You may also have to "fight" against Audyssey's pre-programmed overarching curve depending on the type of adjustment you're trying to make (ie. the rolloff up high and down low. To check how things are looking, save your edits and transfer back to MultEQ app and look in the "room correction results" section. Scroll through all speakers/channels to let it compute the new predicted curve. If something doesn't look right, go back to RB and try again.
So if I want say, a 3 dB notch filter at 120 hz.

#1 115 hz 0 dB
#2 120 hz +3 dB
#3 125 hz 0 dB?

Seriously, I have no life.
Power handling specs don't mean a whole lot. That might be for pink noise or something like that. You can easily damage your speakers with less power than that by shoving the power into a narrow frequency range. And I very much doubt those speakers will do sustained 117 dB as we know it. That would kill them. The 92dB sensitivity is an in-room spec. Those speakers should be able to get loud enough for most people but they aren't for THX Reference level listening. I just blew the driver of a speaker with a similar spec set.

If you like to listen loud, in order to protect the speakers I would advise a high crossover frequency to the sub.
You are absolutely correct Shady. You take speaker handling specs with a barrow full of salt. Drivers get destroyed by over displacement or heat. Over driving damages the suspension, and can the VC if it leaves the gap. So raising the crossover helps that, but hurts the heat issue. The reason is that cone displacement moves air and is a significant factor in VC cooling. Displacement damage can occur in an instant. Heat builds up quickly if you play music with little dynamic range at a high volume.

Electronic key boards are notorious for that, and so are pipe organs, as both can sustain continuous power indefinitely.

In these matters the design of the suspension and especially the motor system are crucial. I spent an interesting afternoon with Billy Woodman of ATC, who showed me in detail how he engineers and builds his motor systems to tolerate such huge powers, in particular, his famed midrange dome.

I'll tell ya tho, it was a little alarming arousing being able to see all 3 drivers bounce back and forth from my seat 15' away. They were jumping! ... Very ... unh ... Hard ... unh!

Oh my Gawd have I already shown you my collection!

That's right out of my second production titled: Port Porn 2 Drivers Need Love 2!

Siiiggghhh one of my all time faves!

Now if you'll I'm exscuse me I'm rather busy all this talk about drivers and ports makes me me want to go um.... Listen to music yeah! And and movies and stuff!!!! Talk to you guys um later!

Okay okay enough fun @Pogre do you mind breaking down when your done listening strengths and weaknesses of each the ultra's versus the new speakers?

I'm getting bored with my bedroom setup and a little later in the year when things calm down I want to get something new

So I'm just curious about your feelings on both speakers something I can use as a reference as I decide what to order to audition

Ascend Acoustics standard issue port. One reviewer referred to them as looking like a "gorilla's anus". :oops:
Sooooooo I'm not sure what that says about me I like gorillas anus's? :oops:

I think I just hit rock bottom guys I'm going to have to get some help :eek:

I've seen a port like that before... Oh yes, it was after the great chili cook off of 19... That was the last time I used a hand held mirror.:eek:

Right about high excursion helping with cooling. I was thinking long the lines of Pogre's speakers which are a three-way design. I would guess the woofers are more at risk of over-excursion rather than over-heating if you really cranked that kind of speaker, but again, it depends on content.

Based on the impedance curve that I saw, those Ascend woofers are sealed so the risk is more that of over-heating than that of over-excursion.
I think the midrange is in its own enclosure but the bottom 2 are ported.

I was mislead by the impedance curve that I saw which only showed a single impedance peak, whereas a ported box will always show two peaks. Previous post was deleted.
Thanks for the info. :)
