89 db sensitivity isnt enough for a mid-bass/woofer. Would suggest 93 db or higher.
i have really incredible sound from my modded skylon deafon iv's. if you want LOUD at 80' plan on some serious amps and if you can go with 10" mid-bass/woofer - you will be ahead of the game.
i went with the following selection and it
is a great sounding setup and highly reccomended.:
Beyma 8" 8g40 @ $150
Selenium 210 Ti @ $35 (there is a new version out)
Selenium 2V2K/350 @ $45
(the crossover is specific for the hcld).
I have to confess, I am NOT a big Eminence fan. There are much better European drivers available (B&C, Beyma, Selenium)
If you can go B&C woofers - they are reasonable priced and BLOW away anything out there and will be comparable to the NVS signature set-up. They will only be limited by amp and overall setup.
This setup isnt cheap but they are STUPID LOUD AND CLEAR at 80' back ( the 2 zapco's 1100 running balanced symbilink from a eclipse 8053 16v balanced head unit may have something to do with it).
Btw, a great budget setup is 4-6x9's (high quality) in a glass enclosure with a big high quality amp.
hope that helps...
