Default Best full range speaker WITH equalisation

Hi,

I think everyone has a favourite full range somewhere. However I am looking at full rangers where if it used by itself is not impressive,maybe a lot of peaks and valleys but if you decide to equalise them via DSP or tone controls, becomes a new thing altogether.

For example you may find a speaker very shouty, but after equalisation the speaker might be very detailed without the shoutiness.

As for myself, I have been messing around with a Faitalpro 3Fe22. However the frequency response tend to be on the rising end with increasing with frequency. This makes the speaker sound a bit thin. However once equalized via DSP, they prove to be extremely detailed and very pleasant to listen to.

Any thoughts?

Generally rising or falling responses are good candidates to be fixed by DSP or tone controls. Maybe one or two peaks at the end of the bandwidth are ok. But you don't want to start with a driver that has several peaks and valleys, because you will never be able to perfectly EQ out the resonant behavior.

I've read good things about the 3Fe22. Of course the Vifa TC9 is the star performer here. Others in the Peerless range are not bad either, TG9 others. And the Scan Speak 10F range is good too.

Hi ra7,

Agreed on not too much fixing. What I meant was, if you could take frequency response out of the consideration and you could now focus on other parameters, transient response, uncontrolled resonance, details, microtexture, imaging will now come into play. What would be then your favorite speaker. Can be a large speaker too like an 8". Not necessarily a 3-4 inch.

Well, the other thing you cannot fix with EQ is dispersion. An 8" driver will start beaming around 1700 Hz. Some people like that sound with no reflections, but most prefer the late arriving reflections from wide dispersion. Even the Vifa TC9, which is a 2.5" driver starts beaming around 6 kHz or so. Not ideal, but not too bad.

In the case of a hi-Q resonance you can make it essentially flat with EQ, but the resonance is still there. To properly tackle such a resonance you need to do it at the source.

My thoughts on the beaming issue when it comes to small full range, it can be solved by putting the speaker at an angle so it crosses at the listener. And another speaker facing outwards to get the reflections off the wall. Bose used to do that with their AM5 and the Jewel cube system. The Jewel cube sounded not bad, but the AM5 didn't have any sparkle in the sound.

The soundstage was really huge though. I am not impressed at all with the present day Bose system and their new satellites.

Some people just add in a rear firing tweeter. For myself I added in a rear firing ribbon tweeter with an extra amp with a 30ms delay via DSP.

But you are correct in that many qualities can't be corrected by DSP. But I would like to highlight that what I am interested in is other qualities of the speaker driver if we could correct for the frequency response. I am not debating the pros and cons of using DSP with full range drivers.

For example, I own the SEAS FA22RCZ as well. You could try boosting the treble all you want but the treble just doesn't have the sizzling quality. On the other hand, I also have the Dayton Audio PS-220-8. That speaker has real treble. even without any boosting.

My two cents.

Actually I think I did not make myself clear. My apologies for that.

The question is

What speaker driver would be your favourite full ranger (either standalone or FAST) if you are using it with a DSP or some form of analog frequency compensation?

Regardless of DSP, the Alpair 7.3eN (or maybe the MOAP version and it doesn’t break when EnABLed).

Dear Dave,

Would love to try your enabled speakers one day. I still have a log queue of speakers seeking my attention. I sometimes think this might be how the emperor of China feels with his 1000 concubines.

You should consider giving the Faitalpro 3 Fe22 a shot with the enabled treatment. I can just imagine, the bright yellow dots against a black background.

I have the original Alpair 6. I haven't played with it for a while. I think I should take it out and see how it compares...

Exactly!

Then after damping sharp resonances at the source, something can be done (-24 dB from top to bottom, i.e. some settings are at -13 dB). ;-)
