I built a LABhorn 3 years ago,and have been using it in my music/HT system. I take the LFE signal(crossover 90 hz)thru a y-connector to both channels of a Carver TFM-42 amp(SUPER OVERKILL!500 w/ch @ 4 ohms) one channel for each driver.I normally have the LFE output cut -18 db for music,for DVDs I kick it up to -12 db to match the main speakers.
Under normal use the 4watt output LEDs on the amp don't even flicker,('splosions,depth charges,cannons,etc),but its fun to crank it up sometimes,and watch things fall off of shelves...hehehe...
Corner loaded,it works down to 30 hz,then falls rapidly,but it can still shake the whole house at 20 hz with no problems(except the neighbors).As Tom mentioned,it can be equalized easily,and still have plenty of headroom.
I would recommend a SS amp,10 watts would be plenty,but if you are crazy like me, a bigger amp is much more fun.
My walls are flimsy 1/2" drywall,but I think that is actually a good thing...a giant bass trap...I've heard horns (not LAB)in basements with concrete walls and floor that were kinda boomy.
One LABhorn will do quite nicely with your system,but if you have the room,by all means use two. I've been thinking about building another one myself.For stereo bass,not because I need more output.
Bill Fitzmaurice's horns look interesting,too,but I have no experience with them,so I don't know how they would compare.
Anyway,IMHO,bass horns are the way to go,especially if your main speakers are horns.As they say:"it takes a horn to catch a horn."
"May the Bass be with you!"
