LP Matador quinto compared to Aspire Conga, both 11"

Hello,
I bought an 11" quinto LP Matador off of Craigslist yesterday. Ive already got an 11" LP Aspire (in the Aspire line an 11" drum is the Conga) but the Aspire has the black hardware and the Matador has chrome hardware so i figured that since i was getting the Matador at a pretty good price, it would just be an upgrade for the Aspire and id sell the Aspire for the same $$ that i paid for the Matador and have a better drum for free. Both are the deep red wood color.
I got the Matador home and put it side by side with the Aspire. (I removed the 9.25" Toca from the stand and put the Matador in its place.) It wasnt long before i began to think id be keeping the Aspire. Even though both are 11" drums, the tones are clearly different. I noticed that the Matador is 2" taller than the Aspire, and fatter around the belly. A cloth tape tells me the Aspire is 46.5 inches in circumfrence. The Matador is 49.25" around. Im guessing these length and girth differences account for the deeper tone in the Matador.
So, my question. What sort of tone difference is there between 3 sizes of drums of a similar series? From what ive read...the relation should be a quarter or harmonic fifth. (the 'here comes the bride' example). Is that the standard seperation? It seems that by my rough estimate the 11" Matado compared to the 11" Aspire is nearly this tone difference.
The difference between my 9.5" Toca to the 11" Aspire is wider than a harmonic 5th.
