I received my Delta Pro-15As on Sept. 28. I installed them in my existing home stereo system on Sept. 29. I feel like I just bought a whole new stereo system. I can't believe the difference in the midrange and bass. I needed a high sensitive speaker for my 2 watt SET tube amp. It kicks. CH

SINCE the usable frequencies of a guitar are right in line with this speaker and its dB sensitivity makes it very powerful sounding but tight--not flabby at all. The only thing missing with this speaker is a aluminum voice coil cap and it'd be vintage 60s/70s. The speaker really moves air like the old JBL cones--but not flabby on the bottom end or overly bright needing a diffuser--ala some D-150s. Was amazed at how nicely this worked in a 120 watt tube amplifier. I'd buy again if it had just a tad more top end (aluminum cone cap). Really nice speaker.
