L4 vice L3

[helotaxi 46]

Planning on pairing one or the other with the L1 and taking advantage of the group buy. My question becomes which is going to be better for my application? I'm quite sure that I can fit the L3 in the A-pillar, not so sure about the L4. The tweet will likely be an A-pillar install either way. The L3 would be a pretty simple install the L4 not so much. I'm not sure that I need the extra top end of the L4 since it will be paired with a tweet. Through the midrange freqs (say 250hz-10k) is the L4 worth the extra money and install hassle? I should be able to get the L3 much more on-axis if that matters.

Thanks for any inputs.
