In-Room responce measurement with Legacy Focus SE speakers


Evening all,

Odd request or question for folks with Legacy Focus SE speakers.  I am doing some VERY casual speaker tests and room response measurements of dads big system.  I have Legacy's smaller Studio HD bookshelf speakers, and have a VERY small space and I think they are incredible.  In hearing my dad's much larger room/speakers/system (his listening room is literally the size of my tiny home!) with his larger Legacy Focus SE speakers.....I am honestly a bit underwhelmed, especially considering I have the 1/8th size Studios, and in my room/system they sound incredible.

In my home, the Studio bookshelf speakers  sound 'mostly' full, warm, very taunt and articulate, and there is the right match of the tone of most all instruments and it's "weight".  Like the pluck or strum of a guitar that is percussive, actually has a bit of an impact on your body.  However, my dads system lacks this 'impact' or body and weight.  Listening at 70-75decibell level is actually grating and feels like your head is being a bit compressed, but it doesn't "sound loud".  My dad mentioned he usually doesn't play anywhere above 60ish decibels because of this issue. 

Attached (I hope) is a screen shot of REW in room measurement of my system with the Studio HD bookshelf speakers for reference to what I am hearing.  In my fathers system, there is a pronounced 100-130hz peak/hump and things sort of trail off rapidly in BOTH higher and lower frequencies.  I'm trying to get a similar measurement to illustrate, but thought I would try to get some thoughts first. 

Thanks for time!!

Yeah, I think that the speakers are too far from the front wall plus their location may have room node cancellation. Try moving them the toward the front wall (behind the speakers) 1 foot at a time to get a rough idea if that improves. His side walls are far enough away but something at the first reflection point to absorb will help. The Rega Ellicit Mk4 is not a high powered amp so it's adequate for power but not going to deliver strong bass with out some room reinforcement. JMHO. Moving speakers is free. You may fin that 4 feet out sounds fuller in the midrange and bass. 

@elliottbnewcombjr Thanks for the idea and links for things!  This is exactly what I am wanting to do, using Room EQ Wizard (REW) just to get a very crude general idea of what the speaker is doing at the listening position with it's ability to play and record a frequency sweep.  I have a mic, and REW generates the sweep itself and records it in sync.  I also think REW has the ability to 'eq' some to the audio being output (audio out from headphone jack or via USB to DAC), so I could theoretically do a little crude tweaking for testing.  

The big thing I am seeing is trying to 'fill the space' some: it's very empty in general, and large in volume.  As @erik_squires mentioned, I think what is happening is long delay times, and a bit of that effect of having your speakers outside: there is no reinforcement of lower tones/frequencies, and mid to upper frequencies ARE being reinforced and just doing their own thing.

OP:

Yep, so the frequency response plots won't help you as much as time/energy plots.  REW has a number of tools for this, but their own forums are better places to go. 

With my own tools there's usually a gated measurement in the mid-high frequencies specifically to remove reflections from the measurement.  This lets me measure more or less, how well the direct sound reaches my room, but does nothing to tell me about intelligibility. 

This is why we turn to other views like waterfall and decay plots.

Best,

eric is right,

my method is to find the best you can, then consider room treatments, not start/try/guess room treatments without measurements.

I understand you young whippersnappers like sweeps, software, automatic calibration ...

I like single tones, every 1/3 octave, hand written chart. old school!

One last thought, OP:

You can use basic tone controls to bring out the bass, but generally speaking the better order of operations is to add room treatments first and then EQ/room correction afterwards.  Of course, using a bass control is easy, so you may want to just do that until you decide about the room treatments, but since the room treatments affect the tonal balance, be prepared to do it again, so for this reason I strongly suggest AGAINST big hammer approaches like room correction being your first option.

Best,
