previously owned IV and V models had 1 tweeter die from manufacture defect. Reliability problems really don't exist in my experience these designs have enough drivers employed so none are really stressed. A first order crossover is phase correct which is very important to sound quality But requires more drivers if it's going to be reliable at higher volumes something the Dunlavy has no problems whatsoever doing for extended time periods. satisfied definitely both are excellent especially at their used prices. yes there is better speakers available but it's going to cost alot more money for that small improvement over the Dunlavy you achieve. Resolution is just about perfect not too much and not really lacking any ether. Especially good for lesser quality recordings this is very important. they have excellent bass and soundstage very well also Did I mention they definitely will play rock music very well they also are very good match for tube amplifiers. upgrade the binding posts for a nice overall improvement.
