2 of these. <link> If its a very large loft consider 2 of the 15" versions. Good performers and 5 year warranty.

Deal of a lifetime. Missing some tweeter arrays but those would be minor cost if you went with Piezo's.

Full range with lower power amps or properly crossed over to a sub near 90 Hz its a great alternative.

You can use Arauco Radiata pine 1/2" as well if you like to save a bit. The amount of plywood you will need depends on cabinet width you intend to build.

Yes.

Either will coast along even at ear bleeding volumes.

2 wider Table Tuba's. The standard recommended 10 is all you need, that other driver needs a gasket to mount and will only net you a negligible advantage in output in this design. Used dozens of that 10 & 12" Dayton classic in other designs with zero problems.

There is no comparison, even the smaller Table Tuba with an 8" driver would be a substantial upgrade.

Basics first, check for leaks. Run a 20 Hz tone through the system and use a small vacuum line (1/4" or so) one end to your ear and the other go around all the seams, feet and such. You will hear any leak once you run into one. Cracked basket frames, check them well. Loose components, check by hand. Unplug the unit first of course.

Roofing ice damming material with the sticky back works too. Used the stuff from McMaster-Carr as well. Most of my use was automotive related but same stuff.

Lysol kills mold on contact, do not dampen the cone.

Has the mold eaten through the cone ? Hold a flashlight on one side and look at it from the other side. If its OK and you're not sure if the mold is dead spray it lightly with Lysol to kill it. Check for leaks and may as well run the drivers out of the cabinet to eliminate those.

These little rubber feet work good.

Either way one of the horns are installed properly.

Chart 1/8 space, 1 watt.

Those tweeters are installed improperly.

Here is a little one <link> Not exactly low output either, it would give a pretty good sized pro sound cabinet a run for its money.

The La Scala bass bin is a short horn, subs are a different design. At the expense of output. Small driver, small horn = low output.

Just like any other direct radiating subwoofer. Sealed subwoofers for home audio commonly use DSP to boost low frequencies.

With a horn ? I never said that and no its not.

The length of the horn has a large impact on frequency response, low frequency sound waves are long so they need a longer horn. A horn is an amplifier by definition.

Dad took me to the moving pictures tour in 1981 as i was only 12 at the time, i remember how impressed he was about 3 guys putting out that much sound. Sad to see him go.

Even with a cabinet redesign using a neodymium motor woofer it would quite the weight loss. Probably a misprint.

Ebay normally lists those if you have no luck here.

DSP and bass bin braces make for a much better sounding La Scala.
