A couple things: The JTR Cap sensitivity is listed as 91db on their site. The dayton's are indeed 89db sensitive, but there are twice as many drivers. Yes, the Caps will still be a bit more efficient around tune. However, in the midbass region, xmax/excursion is not as big of a factor as is sensitivity and displacement - both were/are being fed the same power from the Crown.
And yes the JTR does also have a lot of headroom in the midbass area, and they also sound great. The Daytons are pretty awesome though from what I've heard so far.
Are you visiting you're in laws over the holidays?
Thanks for the complements, much appreciated. Here are my building costs - some money could be saved like primer, magnets, grills, etc if you did not want that stuff.
4 X Dayton 18 HO drivers - 933
4 sheets 4x8 ply, cabinet grade - 123
2 x binding post plates - 13
black screws for binding posts - 5
#10 x 1.5" spax screws for Drivers - 10
1 gallon primer - enough for probably 8 boxes - 18
3 tubes of PL premium sealant/glue - 15
1 gallon duratex - not used yet but enough for many boxes including a roller, 2 extra pads, and shipping - 72.00
Magnets for grills 40
14 pounds of polyfill from Walmart, not used yet - 42
1 X Crown XLS5000 (when it was on special with coupon) $533
1 x Minidsp with shipping $165
Wood for grill frames - approximately 10.00 for 1x4's ripped down
Cloth for speaker grill fabric - 15
Feet for enclosures - FREE thanks to my boy popalock
Sandpaper = already had like 50 sheets of 120 / 150 / 320 grits, but if you need to buy this add maybe 5.00.
Wire - already had a spool of monoprice 12 gauge, but if you needed to buy I used about 12 feet overall. 5.00 maybe?
Total = $1994. Not too shabby.
Subtract out the amp and EQ = 1296 including my fancy coatings and grill materials.
I think that's it.
