My transmission line subs 4-21"

[ajhockett]

these are based on the legend of "el pipe o". post any questions u have

Which frequency range are you covering with the subs?

Just curious as to how high and low they go in your setup. Do the drivers need a high pass to prevent over-excursion?

How are you avoiding constructive/destructive intererence between subs?

Regards, Ben

the tubes are 10.5 feet with 30lbs of stuffing in each. I dont need a lowpass on these, they will take a 10 - 16hz wave at full power. They are placed very accurately in their space, that helps with any losses. I normally pop my 30amp circuit breaker before i would any excursion issues.

I wonder what would happen if I put those in to my small apartment? Would the neighbors mind?

Do you have the mechanical specs on these subs?
I have looked numerous times online and have only found basic info.
I like the look of your HT setup.
Props

 

[ajhockett]

Well PLEASE DO POST them when you get the chance.
Would be lovely it it turned out to be a decent speaker for a PA environment.
