Optimum Transient Response 3-Way Loudspeakers?

For Sale - three-way passive loudspeakers, direct from manufacturer. As a result without DSP- very good Step Response, which gives:

Natural timbres, fine details, 3D image, air around voices and instruments and most of all - the emotion of an explosive attack as is the Transient Processes at "live".

Of course, dynamic, emotionality, musicality, accuracy, resolution and texture are result in such a project!

Dramatic feelings of unexpected nuances so far - especially in styles such as: Funk, Soul, Jazz, Rock, Classic and "any" others.

I offer single pairs (boutique products) for people "awakened" for Time Aligned speakers.

The optimal Time Domain can be judged by Transient Analysis - which I publish.

I am selling my speakers with one year warranty.

Possibility to listen before payment to all amateurs, consumers, connoisseurs, collectioners and for audiophiles with demanding ears - highly recommended!

Tipe: Bass Reflex, Floor standing, Without Time Distortion!

Attention - the crossovers are at the back outside the speakers.

Option for cones or rollers.
Recommended cables - Audioquest Midnight.
Recommended amplifier - without global feedback with Sziklai circuit.

Parameters
  • Frequency Response: 41 Hz - 20 kHz +/-1.5db(anechoic condition)
  • Sensitivity: 91 db/1W/1meter
  • Impedance: 8 ohms
  • Power: 60 W RMS; 120 W Maximum music
  • Sizes: Height 111cm; Width 49cm; Depth 53cm.

The frequency response is measured in untreated home room.

Thank you for the question.
Serious and correct inquiry.
Yes - there are some givens that may not be a problem.
In the absence of Time Distortion, only the specific "flavor savor"(aftertaste) of drivers, capacitors,
resistors and inductors remains!
These speakers (concept) depend on the quality of the source, amplifier and cables.
Attacking with a bad and problematic signal - gives his "shameless" answer.
The interesting thing in this case is that the dependence on the acoustics of the room is insignificant.
And a philosophical sophistry - the emotional reaction is crucially dependent on the sound culture and technical intelligence of the listener.
If a tube amplifier with "parasitic" high output resistance is connected - will get more bass.
There will be a similar result from positioning near walls and corners.
The Question is, of course, subjective preferences, but this can impair the good Step Response.
 
Answer for TNT
It is not easy in simple words, but I will try to explain the design aspect with popular logic.
When some speakers have very good Time Aligned – ie. smaller possible (any resultant) distortions, then the direct signal along the axis lines incl. and the reflections will collectively have less distortion reaching the listener. Other speakers with Time Distortion will have more "dirt" coming and from reflections as well.
The directionality of the individual drivers is hardly a factor in this aspect.
 
I was more interested in the SPL, not (acoustic) phase.
Clarification!
The average SPL is always based on the driver with the lowest sensitivity.
In this case, the mids and highs are equalized relative to the bass driver.
In the specific case - the Sensitivity is 89 db with 10" Vifa bass driver or 91db with 10" Audax bass driver.
And last but not least - clarification is needed: What level do we supply to the given DUT ?
It is usually 1 watt per 1 meter.
In this sense, SPL and Sensitivity are close and almost the same parameters.

Ok, I got confused by your post #14, because it mentioned "phase response" and the plots show two y-axes (dBV on the left, phase on the right). Are you saying the plots in your post #14 are the SPL curves?

Anyway, the curves extend down to 10 Hz. Either you have an anechoic chamber, or you are showing the response including the room response. I am interested in the anechoic SPL curves.

Please clarify.

Can you post the impulse response data (data file, not graphics)?
 
The data file is too large and cannot be accepted by the system.
The data should not be large at all. A 1 second long sequence of data points at 8-byte double precision would be 1.5 MB at 192 kHz sampling rate, or 350 kB at 44 kHz. You can ZIP it to post here, or send me a PM.
The graphs from post #14 are phase characteristics!
Ok, can you show the anechoic SPL instead?
