Sound waves arent round, they are waves. If they were round, they wouldnt be waves.
The problem with oval speakers is from 1.5K to 4Khz they get second and third order harmonics that can cancel out some frequencies and boost others makeing them hard to balence in the upper midrange frequencies. Because of their mounting location it becomes a non issue as they will reflect off the dashboard and will have other sound issues I have to tune for. The reason oval speakers work well in cars is beacuse with all the angles and refective surfaces in alot of cases will work with the speakers issues and result in correct sound.
I have heard the Diamonds and dont like them
Now the Alpines have a $499 msrp and the Bostons are $379 msrp. Eaither one will run me $175 beacuse with the Bostons I have to spend another $10-$15 for the 6x8 adapter that the Alpines come with.
I have no doubt the Alpines will have more bass kick but can they respond (attack and decay) as quickly and produce drums as accuratly. And the highs should be just as crisp but will they be harsh as well? I wish there was someplace around here I could go listen to them
The ONLY reason I am looking at the Alpines is because you recommended them. While I have installed them (other series) on numerous occasions and know they sound good I guess they didnt strike me hard enough to say "Hey, Im gonna get thoes next"
And I have been through ALOT of speakers. Just some of the fronts I have had: Infinity Kappa;Refrence;Beta;Kappa Uniplane, Boston SX;SL;S;Pro, Rockford Series1;Punch;Power;P1,2,3, OZ Audio, Clarion Pro Audio, Concept, ADS, Nakamichi, MB Quart Premium;Discus;Refrence, Kenwood Excelon, Soundstream SPL;Refrence, Audiobahn 6.3Pro, Crystal Titaniums, Diamond, Advant etc etc.
I have heard them all but save for a few.
If I could build my own I would get a pair of Infinity Beta 6.5" Midbass, Dyna Audio 3" dome midrange and Infinity Kappa EMIT tweeter with a MB Quart Pro Comp 3-way x-over.
It would sound so freakin good! But alas I cannot find any of thoes components any more
