Since you said you would consider DIY, my recommendation is to add a Zobel Network to each driver in the enclosure. Almost every loudspeaker can be improved by flattening the impedance curve and therefore allowing the crossover to perform at its best. All you need to do is remove each speaker, disconnect the wires, and measure the DC resistance and Inductance with a meter. Attach the calculated resistor and capacitor in series between the terminals, reattach the wires and replace the speaker.

If you are really keen, you could then add a Zobel Network to the external loudspeaker terminals after doing fresh measurements, and then perhaps even add another Zobel Network at the amplifier. Disconnect the speaker wires and measure the resistance and inductance of the wires while still connected to the speaker.
Can you give me your speaker suggestions?
Currently looking for new speakers as I have grown tired with mine, I would greatly appreciate any suggestions that you think would fit my needs!
I had a pair of heresy iii speakers and loved the sound from 600hz and up but felt pretty much everything below that was thin sounding with no weight. I built a bigger ported cabinet for the drivers and it made a decent improvement from say 40-90hz ish but I still needed a subwoofer. 100-400hz still sounded thin, drums lack that punch and impact and male vocals lack weight and presence.
Basically I am looking for a speaker that gives you the "musicians are in the room" feeling that the heresy gives me but deliver more in the lower midrange/upper bass area.
I listen to jazz, femal/male vocals, 70's rock, 80' pop etc.. across all genres the heresy is equally good and equally bad (no matter what genre it feels like the 100-400hz area is sucked out of the room).. speaking of the room im in a 15foot by 22 foot room (its an L shape, half way down the 22 foot wall extends another 22 feet about 550sqft total). not an ideal room but its the only place I have.
I am using a prima luna prologue premium with 37ish watt/channel, I currently purchased a Pathos logos mk ii with 110wpc into 8, and immediately noticed my main area of concern sounded even thinner, the more powerful hybrid amp sounds less powerful, less meat on the bones if that makes sense. when I get new speakers, I will sell one of the amps.
my current budget is around $4-6K USD, I would consider purchasing used, or even a diy kit.
the sonetto V reviews seem to tell me they will fit my needs, does anyone have any thoughts?
thank you in advanced!!
