Yeah, but plywood is cheap and the result is audibly noticeable. Baffle extensions were recommended for all of the Altec VOT cabinets too. Make a big improvement for cheap if you have the space.
As the frequency decreases and output becomes more omnidirectional, the baffle provides a +3dB reinforcement like a close wall would. With 250hz around 5ft wavelength you can get a good mid-bass boost with a sheet of plywood. |

Is not about the cost of plywood bit the placement cost if the speakers have this type wings. Sure, for monophonic films in 40s and multitude listeners in this it was not a problems but for contemporary stereophonic sound it make the speaker positioning very difficult if even possible as this type of speaks even in very large room would have very limited option to placed them in the room.

It is not "open baffle" and the upper frequencies come out of the horn which is above and apart from the baffle. 800hz crossover. Have another look at the picture. You are confusing this L-9 with some other topology, I think. |

From the prospective I described above it is the "open baffle". Take any loudspeaker, even contemporary monitor and pace a 3 feet by 5 feet untreated board between them. Listed how that surface dry out sound and kill imaging. Do not call it "open baffle" if you would like to, call it “oversized baffle”.

That WE logo must be very powerful since at least 20 online show reports named this old junker "Best of Show"! Most of the German forum threads have a few guys who thought it was the best thing there. |

Ohl, here is the ultimate price! Are you one of the men who watch the Miss America shows? BTW, the fact that your German forums junkers find your WE as the Best of Show is not the indication of WE sound but the indication of level of the Show.

We were quick to remind everybody that this was a second-rate WE system but they didn't seem to care. To my ear it was a bit more "vintage sounding" than the field coil WE gear and it wasn't "perfection" but at least it had some soul, which most of the plastic speakers at the show lacked. Also, for many of the visitors this is the first time they heard a decent sized horn and that probably explains a lot of it. We are tempted to bring a theater-type system that is a step above the L-9 next year, since this was such a hit. |

The fact that your Korean friends would like to expose the sound of this WE collection to public is not bad but there is concern of my in all of it as well. You and your friends are not in the business to facilitate better sound for the visitors but rather to build up publicity for audio yahoos. You might drag a few years some vintage gear to the show as some local folks did in the 2001-2002 in US but soon or later your Silbatone guys would need to build some kind of bridge between the hype you will be creating with your WE and the current Silbatone production. I do not see this bridge easy to build. Also, soon or later you will recognize that comments of online posters do not push sales figures. I wish your Silbatone people have enough perseverance and money to demo their WE gear with having any financial gratitude.
