Playable, correctly spelled, and not how the chord is normally voiced. Right now this is the shapes that put a ninth, eleventh or thirteenth below the root.
Eb11 is Eb, Bb, Db, F and Ab — Eb9 with the eleventh added, and the third usually dropped.
It sounds suspended rather than tense. The eleventh sits a semitone above the major third, so the third is usually dropped; some shapes here keep it anyway.
Dominant — but effectively a sus chord with a ninth.

| Eb | Bb | Db | F | Ab |
|---|---|---|---|---|
| 1 | 5 | ♭7 | 9 | 11 |
Also written Eb9sus4 or Eb dominant 11. The same chord either way; which spelling you meet depends on who wrote the chart.
Five notes and four fingers, so something has to go. Keep F, Ab and Db (they fix the quality). Let Bb and Eb go, in that order — a perfect fifth says nothing the root has not, and in a band the bass has the root.
All 5 common shapes as fret numbers, lowest string first. Hover or tap one to see it drawn.
Eb11 is the V of Ab, and that is where it goes if it goes anywhere: the third and the flat seventh are a tritone apart, and both resolve by a semitone into Ab.
In a phrase:Bbm7→Eb11→Abmaj7— the ii–V–I of Ab.
Voice by voice, Eb11 → Ab. One voice moves by a semitone, and 2 notes are common to both chords.

| F, the ninth | falls a whole tone | Eb, the fifth |
| Ab, the eleventh | stays where it is | Ab, the root |
