A cheap driver like those from the likes of Dayton Audio? No, in this day and age even products from the likes of Dayton Audio measure exceptionally well and sound just as good. Price and exoticness doesn't guarantee "transparency" or ease of use just like Beyerdynamic's Telsa drivers don't guarantee better performance than their decades old drivers despite costing significantly more. More often than not, I haven't seen a lot of evidence that really expensive and exotic drivers are heads and shoulders better than the competition...companies like Bowers and Wilkins seem to use stuff like diamond tweeters and Kevlar woofers more as a marketing term.
I thought I was pretty clear in my post...basically the overall component choice is mostly irrelevant. Yes, certain components are objectively better than others but in the grand scheme of things its a pretty small aspect of speaker design. Especially when the real magic is in the actual crossover and cabinet design.
Case in point: the KEF Q300's cost-cutting first order crossover results in obvious cone breakup. Since the Q300 uses a 6.5" cone, you get a double whammy of earlier cone breakup and inconsistent dispersion. Unfortunately, the part you can't see seems to be the first thing that goes under cost-cutting so poor crossover design seems to be an extremely common occurrence with Hi-Fi speakers...even with higher end multi-thousand dollar passives like those from ATC.
So 100 out 100 times I would pick a speaker with "cheap" drivers that actually use a properly designed crossover over an expensive speaker with an average crossover. The JBL LSR305 or Philharmonic Audio's Affordable Accuracy Monitor don't really use expensive parts but honestly sound better than a lot of more far more expensive speakers for a reason.
No idea, not a whole lot of detailed information regarding them.
At around the $200-$300 price range, Philharmonic Audio's Affordable Accuracy Monitor should be one of the best on the market. Dennis, the owner, basically takes a good Dayton Audio DIY kit with larger 6.5" woofers and implements a much improved 4th order crossover that also decreases the crossover frequency. Measurements definitely indicate its better than the ELAC B5 that everyone is going nuts over right now.
I emailed them to order a pair of AA monitors, thanks a bunch man I always love to hear your impressions because I think we share some of the same opinions in terms of preferred sound signature. I actually have around $400/$450 to spend on a pair, not sure if there's anything else I should consider before I jump on these...
