ELAC Unifi Reference teasers

[restorer-john]

I liked @Hotwetrat 's description of what he'd do to SMSL's letterbox. Fuggin' hilarious.

If they pulled that shit with me and I found out I'd piss through there letterbox - as a start.

Sounds like a bloke to have quite a few ales with on a friday night.

Contradicting voices are always welcome but please with some real content and not just paltry street expressions.

He did an impression of McGregor, I thought it was quite funny.

 

[MrOtto]

Wow, so many useless posts in a row. Good job ruining this topic.

Count me in!

Just remember the ASR credo: "Come here to have fun, be ready to be teased and not take online life too seriously."

 

[abdo123]

Ahhhh so close to being perfect to what I want - except it has port on front, not rear/bottom

In what situation would a front port be bad?

 

[Music1969]

In what situation would a front port be bad?

Only In the situations where front port resonance has shown up in measurements

Seems to be often

 

[Hotwetrat]

Same old

They can create some pretty serious cancellation dips if you're not careful with the design. Neumann in particular seems to be very good at dealing with this, but it's damned hard to get right.

As do rear ports.

Based on what I have experienced, I'd take a problematic front port over a problematic rear port. The former tends to result in a dip where the latter results in a peak, on-axis.

Wouldn't you want a peak, so it could be EQ'd down? Maybe I am missing your point though.

 

[hardisj]

If you have EQ, I guess. But I'm just going off raw performance. Also, it seems a lot of the resonances I see from ports are very narrow in nature; most EQ won't be able to have a high enough Q to target just the peak without altering other frequencies around it. Dips are less noticeable (less offensive) as peaks.

 

[Music1969]

As do rear ports.

Rear port resonances show up in measurements at the front ?

 

[McFly]

In anechoic chambers, not so much. In room, a lot more.

 

[hardisj]

Rear port resonances show up in measurements at the front ?

Yep. Because they often radiate omnidirectionally.

 

[abdo123]

I asked this exact question in the Youtube comments and you said port resonances beam out from the port and 'can be absorbed'.

 

[hardisj]

It depends on the size and frequency. This is why I said "often". If it is high frequency and the port is large relative to the wavelength then it would be non-directional. If it is low and the port is small, it would be closer to omni. Stuffing a port completely seals it off; stopping the resonance from ever occurring. So, "it depends" is appropriate.

That hasn't been my experience to be honest, I don't know why but port resonances continued when I stuffed the port.

I know this because i wanted to test whether my 'Klippel EQ' is still valid once i stuff the port.

It probably isn't port resonance, then. Likely enclosure resonance. I just made a post reply about this subject here:

If you guys want a true "teaser" for the UBR62, you really should check out the latest Daily Hi-Fi video. Start at the 9:40 mark.
