ADS L400 Specs..

[fanghorn]

Anyone know the efficency rating of the ADS L400's? Been doing alot of searching but to no avail...

I did some searching and couldn't find a spec sheet or brochure on that model. However, most of the ADS speakers around it's size are rated at 92dB.

Enjoy the forums!

There's a lot of good info here: http://sportsbil.com/ads/

Look at the L400e in the "in-wall and miniatures" document as well as the Braun L420. They'll give you a rough idea.

Keep in mind that there were two different L400 models (plus the L400e). The larger model is probably more efficient by a couple db.

Mine is not the e, and it has the rubber surrounds with the screw type terminals...

Sounds like the earlier enclosure (about 16" tall?). If so, I agree with Urizen's number. The smaller ones are rated somewhere around 87db.

well darn...was hoping they would be less then 88db as I will be using a Luxman M-117 amp on them and right now with my Yamaha NS-200M's I can only click the volume control maybe twice before it gets too loud...

Maybe you can reduce the amp sensitivity or the output level on the preamp. Does the pre-amp have a muting/attenuator switch? Another option is to use a simple attenuator between the pre/power.

I know the L300e and possibly the L400 are 4ohm speakers. I have both L300e and L420 speakers and they sound great with around 100wpc thrown at them with about 1/4 to 1/3 volume.
