Bass Tightening

[jcmusic]

Wayne,
Thanks so much for the observation and notes about my room much appreciated!!! Also that was a great read about the YDP I will look around for one based on what I just read. So to sum things up you feel that other than the things you pointed out my room is not too bad?

Jay

Hey Jay,

I must say that from what I see with your measurements, your original inquest about wanting to tighten up your bass is perplexing. I don’t really see anything in your measurements that would account for the problem. The speakers don’t have much extension to begin with, and your waterfalls don’t show any excessive ringing (i.e. long low freq decay times), except for at 40 Hz, and response is down nearly 15 dB at that point.

That said, judging by the full-range response graph, a good parametric EQ would certainly be useful. Eliminating the wide depression between 600-4 kHz and toning down the peak at ~180 Hz would make a dramatic improvement. I recommend the vintage Yamaha YDP2006. This post contains excerpts from a review I never got around to finishing.

Regards,
Wayne A. Pflughaupt

Hi Jay, I would suggest that indeed you do need eq. And that the Soundcraftsman is not up to the task. The Behringer that was offered to you would be of use as well as the Yamaha that Wayne recommends. Though you may have some time finding the Yamaha, you could try the Behringer in the meantime, while looking for the Yamaha.

I dont see why Wayne is perplexed about your freq response, it appears to me that you have an upper bass boom and an exciting high freq range. Is this how it sounds? Lots of upper bass with a bright top end?

Hi Jay, Also it would be of great help if you could post the m.dat.

Thanks

Hi Wendell,
No it does not sound like that, it sounds great to me other than some of the low bass sounds a little fat ot flabby. Just not tight or sharp.

everytime I try to post it that way it tells me it's not a valid file.

Add it to a Zip file and upload the Zip file. Unless the forum has a smaller file size limit, that should work.

Thanks Ethan.
Here ya go Wendell:Well I tried and the file is too big for the site. I can not make it small enough the forum's limit is 976.6kb I can only get it down to 1.78mb...

Hi Jay, You can post the m.dat over at ht shack.

They are already there in this thread......http://www.hometheatershack.com/forums/rew-forum/69795-new-measurements.html

Hi Jay, I am back after a hectic weekend of having almost a hundred friends at my house for a party celebrating Italian motorcycles.

I down loaded your m.dats and they generally look reliable. Are you confident for now that they are representative of what you hear as far as freq response goes?

Are you happy with the bass level (besides the overhang) that you are hearing?

The m.dats that you posted say one is flat and one is with eq, in the graph with eq we see a 2db increase in level is this just insertion gain?

Hi Wendell,
Before we go any further take a look here http://www.hometheatershack.com/forums/home-audio-acoustics/69608-room-treatment-help-2.html these are the graphs from yesterday, I discovered the increase in gain going through the eq so I redid them and added the mic calibration file.

Hi Jay, Ok so the two m.dats are;

The first being "flat", without the equalizer connected in the system at all.

And the second is with the equalizer in the system, but with all controls set to flat. So you see the equalizer adds 2 db to the overall gain of your system.

Is this correct?

Wendell

 

[jcmusic]

Hi Wendell,
The one that says flat is with the eq in the system and all controls set to flat, the one that says eq is after I made adjustments and where it currently is set.

Jay

 

[theguesswho]

Hi Jay, what adjustments did you make to the eq?

Wendell

 

[jcmusic]

Wendell,
For the most part what I did was to increase the frequency's that where real low by a small amount, and decrease the high peaks by a small amount. This is really a learning expirence for me right now, I am using a vintage graphic eq which is limited. I have a digital parametric eq in the mail should be here next week.

 

[theguesswho]

Hi jay, which equalizer did you buy?

Wendell

 

[jcmusic]

The Yamaha YDP 2006, the one Wayne recommanded!!!

Nice one!

 

[jcmusic]

Well I got the Yamaha up and runing this thing is nice nice nice!!! there is a bit of a learning curve though. I have never had a parametric eq before it's quite nice and I am enjoying learning what it can do.
