My previous home theatre/multimedia system consisted of a pair of l36 decades on top of the shelves in my icon, and a JBL EC25BE 2-way Dual 5-inch Center Channel speaker (Beech) to match the beech shelves. It worked fairly well, sitting directly above the TV. I have a pair of G20s (I think) mounted on the back wall for surround, and a cheap Sony amplified Sub on the front-side of the room. I only use the sub and rear surrounds for movies - my JVC receiver is smart enough to remember settings, it just plays the front left/right speakers for music use.
In February I got the big 4320 monitors and have rebuilt them, adding 2405 slot tweeters and update the crossovers to match.
But now during TV and movies, the center channel audio (dialog) is distinctly different than the front left or right that comes from the horns (2420s - aka L85s) and slots of the big boxes.
After reading about similar projects from many folks here, I figured it just made good sense to make the front wall audio more consistant - so I've obtained another 2405 slot and an LE85 driver with 2307 horn and I plan to use them for the front center channel. I just ordered the parts to build another of Giskard's 4333/S300/L300 equivalent bandbass circuit - (the regular, not the Charge Coupled design) see - http://audioheritage.org/vbulletin/s...42&postcount=3I'm not in a rush to get another 15" just for center use - there should be plenty of Bass from the front left and right, the center is mostly dialog anyway.
I don't even think I really need to build a box for the compression drivers - maybe just a nice wooden tray to support them, tho it'd be nice to have a faceplate to velcro the lens to for the midhorn ...
I'll admit it - I've seen too many pictures of those Japanese collectors' systems with the exposed horns and lenses ... Geek tech!
