Do you think the super 7s suffer due to the cabinet design with regards to the subs?

The Super 7’s only have 2 weaknesses and the subs are not one of them.

On a different topic, when do these freaking MIflex capacitors become stable? Or how many hours till they sound mostly like when fully done cooking.

200 hours.

Thanks Tyson, I read they can take over 500 hours to reach full potential. Today the system sounds awesome, and I’d be happy if this is as good as it gets. Though, I do think I got the subs set up really well and I added the bottom bases and no-rez. And the high pass filter itself helps by reducing the work the Oticas need to do. But I think those capacitors act like a tuning device, changes the tone and overall presentation of the sound.

 So how can a capacitor installed in high pass filter make the sound subjectively better? Shouldn’t nothing or a straight piece of wire be more accurate than any capacitor? 

 I guess complete accuracy isn’t the best way to achieve the most satisfying listening experience. I should right this over at ASR forum, I’d be the subject of an onslaught of insults and scientific schooling.

You might find (as I did), that the inline capacitor is not 100% gains.  There's a tradeoff with them, IME.  They do limit the bass sent to the main speakers, which often is good (especially with bookshelf sized speakers). 

But they also are not completely transparent.  If I were you, I'd run it for a month or 2 in the system, then take it out and see what I liked better.

   Yes I will try that, maybe a dumb question, I don’t think it would hurt to just add a jumper across the capacitor? I think I should know this but what happens if you shunt a capacitor in a high pass filter? I think I’d need to unsolder one side of the capacitor.

[Tyson]

Takes it out of the signal path if not connected on both ends.

Yes, it would  be easy to compare then. Just unsolder one end and use a jumper wire with alligator clips. To hook in or bypass the capacitor.

   Another aspect these subs added to my music listening enjoyment. Drums and bass guitar sound so much better now, and with that NEO tweeter doing the cymbals it’s beyond what I thought a stereo system could do.

 

[Tyson]

Be careful.  With all this extra resolution in your system, you’ll start saying crazy stuff like “I can hear a difference between cables” and “better parts give me better sound”.  😂

[Glady86]

I definitely believe capacitors in the signal path affect the sound quality, I trust what I hear. I don’t need blind testing to confuse me or frequency response testing to “prove” I’m “delusional” 

 I haven’t messed with cables for years. I have mostly DIY from VH Audio, plus their CHEA (I think that’s the name) speaker cables and Pulsar cables for the long run from preamp to power amps. Changing cables to try and fine tune my system isn’t something I like to do.
 
  Whoops, the speaker cable is called CHELA, it looks similar in construction to GR Research speakers cable.

The one thing to keep in mind about the high pass filter is the small phase shift when running vs not running one. I had one in my system and really enjoyed the little extra midrange clarity but the phase shift made integrating sub location a little tricky in my small room. If you have some space, it shouldn't be hard to find the best placement. For me, not running the high pass filter allowed a little better integration and clarity in bass but you can tell the driver in my studios is working a little harder. Everything has a tradeoff. Since I can never leave good-enough alone, I'll probably go back to trying one again later at some point though.

Ok, I’ll bite.

 I tinkered with the phase control. It’s a little above 0 degrees. I don’t know how well I have the subs integrated, but the sound I get now is way above what I had with my previous subs. Also they work just fine for  movies, no complaints.

I’m not one who needs to vibrate the whole house when playing movies. I watched Furiosa A Mad max saga last    night and the sound effects were great, gunshots and roaring engines were impressive to me.

 Here’s an update on my sub placement experience. After plenty of listening with the subs on the side wall and a little behind the speakers, I decided to try them back in between the speakers. Laying them on the sides, but this time a little farther back from the plane of the speakers, close to where I had the sealed subs I used prior. This seems to be the optimal location for my room.

Since I have a projector screen, using the subs in the center would block the view, and is the reason I set them horizontal instead of upright. Just throwing that out there in case anyone has a similar situation, don’t be reluctant to try the subs this way.

Try using your subs as speaker stands like Tyson did. It may seem a bit crazy, but it will probably sound more seamless that way.

I think it would place the tweeters too high.  With an MTM like the Otica, you really want the tweeter to be as close to ear level as possible.

 A design with two woofers on top and two on the bottom of the MTM would align the tweeter close to the height of the normal design. But not sure how it would perform, maybe not as good.

[Tyson]

Subs slightly behind the speakers is fine.  It will just emphasize the leading edge of the bass slightly.  Which is not a bad thing.  As long as you are getting a smooth frequency response between the mains and subs, you're good.

If I wasn't married, I'd have a pair of dual OB servo subs as speaker stands and a pair suspended from the ceiling!!
