Re: Replacement for the NSD 2005

It's drop in. Eminence crossover frequency recommendations are based on a 12dB/octave high pass, we use an 18dB/octave high pass.

Eminence HF Drivers

The NSD 2005 driver has been discontinued. Once existing supplier inventories are sold they won't be available. The Eminence F151M-8 may be substituted for the NSD 2005. The similar neo magnet F151M-8 is not a suitable replacement for the NSD 2005, its resonant frequency/fs is too high.

Re: 2x TLAH pro in progress...

It is only a problem if the resistors get hot, and they handle very little current, so they shouldn't. We've seen it happen, though very rarely, and only when something was wired incorrectly or the system was massively over powered.

Re: 2x TLAH pro in progress...

The most critical place to stuff is near the terminus, the least critical is near the closed end. Put the crossover near the closed end so you don't have to put stuffing around it, and the cab is larger giving more room to place it. You need to use enough stuffing that it's compressed slightly.

Re: OTop 12 to Otop J Array

The sound is the same as the standard version. The only reason to build JArray is when you've got at least two cabs arrayed with high enough placement that the lower cab or two need to be aimed downward to cover the audience in close. The standard OTop 12 has had a phase plug for at least seven years.

Re: Custom Lab15 by Eminence in a T48 or T60

The 3015LF has greater sensitivity in a direct radiator, not in a horn. Their maximum outputs aren't so different that I'd choose one or the other for any criteria other than price and weight.

Re: Custom Lab15 by Eminence in a T48 or T60

The longer xmax is of no advantage as this is a case where the driver thermal and mechanical limits are the same. The lower Fs costs some sensitivity. It may have its advantages in a direct radiator, it doesn't in a horn.

It's not 1100w. The 3015LF is 450w.

Re: Under Garage Home Theater Build

Since you have the ability to fasten the studs to the concrete wall so easily you might as well. May not help, can't hurt.

Re: Custom Lab15 by Eminence in a T48 or T60

The only performance gain would be 3dB higher maximum output between 40 and 50Hz from the longer xmax. Otherwise there's no difference.
