I know that last summer, Ascend had a special promotion where they would pay return shipping like SVS does. From what I read, it looks like you would be out for shipping both ways with Ascend while SVS pays shipping both ways.
Dennis offers 7 days for return, but you would pay shipping both ways. As strange as it may seem, he (expertly) does this as his hobby and does not have the profit margins to absorb shipping costs. That is how the Philharmonitor is $300 less than the Seirra RAAL.
I found a 5.5" ScanSpeak Revelator mid/woof for $210 each:

This looks like the cabinet at $144 each:

I could not find the RAAL tweeter. The least expensive RAAL I could find was the 70-10D which goes for $322 each:

I believe the RAAL Dennis uses (like the one Ascend uses) does not have a replaceable ribbon and that saves money, so lets assume $200 ea. for the tweeters.
That puts us at $1108.
I'm pretty sure Dennis outsources the woodworking (he did not have a wood shop when I visited), so add the cost of cutting the baffles and the port hole in the back, acoustic dampening material, terminals. Then XO board and components. Since you have built a crossover or two, you have a good idea what that costs although I don't know how complex the New Philharmonitor XO is. Lets say $171 ea. for everything in this paragraph.
That puts us at $1450. I'd guess Dennis gets a 25% discount on materials like the speakers and cabinets. He does not have the production quantities to get deep discounts like a large manufacturer would.
That puts the cost at $1085. Obviously, he is not paying himself much for building the XO, assembling, measuring FR, packing, and shipping speakers. He is not trying to earn a living or grow into a big business, he is retired with a reasonable pension. He is just enjoying sharing his talent and passion with other people who enjoy music & audio. Between that and playing violin in the Orchestra, I think he is well into "self-actualization" from Maslow's Hierarchy of Needs.
I went through these numbers as much for my own curiosity as anything, I don't pretend any precision on my guesstimates, but if you've been around the block a time or two, you know I'm not off by too much. Oh, and I forgot about the $50 he donates to the Orchestra for every (pair of?) speaker he sells (excluding the $210/pr AA's)! But to my point, he does not have profit margins to absorb shipping costs!
I know a few of DIY'ers who, once they became familiar with Murphy's speakers, realized they were not going to save a dime doing it themselves.
To YogiBizz, I say Dennis is a hobbyist, but do not misunderstand that to mean he isn't a top notch speaker designer. I believe at this point I can say he designed every speaker that Salk sells (including the flagship $16,000/pair Soundscape S12's). I know he designed the XO for all of them. He has been a mentor for the DIY community for a long time.
