Pioneer Elite SP-EC73 Center Speaker Review

[Alice of Old Vincennes]

Infinity C263 is 3 way. Mid-range is below tweeter. Two 6.5 woofers. Big enclosure. Spinorama is very good for a center channel. Sale ended last week. Amir has Infinity 162 in line to measure

I think we need to be more forgiving of center channel measurements. The design by necessity is flawed. You have to squeeze a speaker under a monitor. I have measured placing a bookshelf under the monitor. I have to place the monitor too high. Looking up at a screen for long periods of time is painful. Monitor over a fireplace makes me cringe. It is like watching sports at a bar. Neck starts aching after 30 minutes.

Pretty Speaker Graphs: Some speakers shoot a laser beam, some shoot out a sword, this one looks like it shot a bullet and there is smoke trailing behind...

THD is falling below 2.6kHz as a result of the high-pass tweeter filter.

I still believe THD is falling below 2.6kHz as a result of low pass filter for mid driver at 2.6khz which is cutting mid output hence THD is falling as well.

Of course there are some mid drivers with THD peaks towards high frequencies, but I have measured dozens of tweeters and almost all have sharp rising THD below some 1.5 - 3 kHz.

That is true. But it seems to large for me as it is below XO so it has been reduced.

Hi, Amir. Just wondering if the KNFS generates phase data for the measurements or if that is one of those 'ups and extras' that cost real money? If it does, could that be included in the Spin data dump?

It does generate phase data, both for the response and for 3-D visualization.

If software can output impulse response as txt-file and the dialog procedure is easy enough to handle IR txt-file could be wrapped into Zip-folder, @48kHz probably something ala below for this ones system phase

Normal TV monitor height (for relaxed viewing) dictates rather low shelf for center loudspeaker, but it is possible (I have done it at several home theater setups). Or placing center speaker just above the monitor. So, the center loudspeaker design is not flawed, the Wife Acceptance Factor is!

Be carefull, wife may hear you.

Uf, bad luck.. May the Force be with you, as nothing else would help.

I just gave Amir the RC263 for review.

Monitor over a fireplace makes me cringe. It is like watching sports at a bar. Neck starts aching after 30 minutes.

This is what I ended up going with.

Gives a little more flexibility for center channel, in addition to the obvious benefit to neck angle.

How do you like? I ordered center.

My wife wanted the TV in the snug over the mantlepiece. She prefers it that way and I certainly haven't noticed any neck ache, ever, and she has had various TVs there over the last 20 years.
She doesn't like "stupidly big" screens either.
I usually watch tv using a projector on a big screen but if the family are together in the snug I watch the one over the mantlepiece and what you write had never occured to me.
Mind you sports bars are not common in England and I've never been in one here...
