Product Details

Speaker L-Pad Attenuator 100W Mono 1" Shaft 8 Ohm

L-pads adjust the relative volume of drivers connected to them by placing added resistance in series. At the same time, a counter-resistance is placed in parallel with the driver to maintain a constant impedance which allows the original crossover design to be used. L-pads are to be placed in between the amplifier and speaker, or in between the crossover and driver. This particular L-pad is rated at 100 watts RMS, is designed to be used with 8 ohm loads, features a 1" shaft length, and comes with mounting hardware and faceplate.

Dimensions: 2-1/2" diameter, 1" depth. 

Note: See the Tech Drawings tab for wiring instructions.

Speaker L-Pad Attenuator 100W Mono 1" Shaft 8 Ohm is rated 4.5909 out of 5 by 22.
Rated 5 out of 5 by from Super for a Guitar amp Attenuator!!!!!I used this to build a basic attenuator for my Fender Super Reverb. It works perfect! No tone loss I built a few others and they made my sound muddy, this L Pad is perfect for up to about 70 watts!

Rated 5 out of 5 by from Nice QualityLarge, beefy variable L-Pad can handle a lot of power and does a great job of fine attenuation that is consistent across its range. Worked like a charm to match my efficient tweeters to my less efficient midrange and woofer. Be sure that you have a 2-1/2" open space on your baffle to mount it and that the baffle is at least 3/4" thick. Wiring is simple and the connections hold solder nicely. Instead of recessing, I opted to open the center hole of the cosmetic plastic square plate to fit over the center nut that protrudes when mounted, and used simple double sided tape to adhere the plate to the baffle. The knob easily hides the center nut.

Rated 5 out of 5 by from great LPADi used for tube amp. excellent product. you should buy it

Rated 5 out of 5 by from Perfect fit, works smoothly, high quality.I purchased these to replace tweeter controls in the cross-overs of a pair of ESS AMT 10b speakers. The Heils are now back to sounding as good as new. Very clean/clear sound.

Rated 5 out of 5 by from Solid performanceWired these up/installed to control a high output midrange in my home 3-way speaker system. Very heavy duty construction and simply installation. I used a 3/8" drill bit and a deep well socket to tighten the nut. The speaker is acoustically sealed and there was no air leak. The L-pad is basically a rheostat type varactor and works as advertised. Speakers impedance changes when voltages are induced...best to get this L-pad set and then check the impedance at the speaker wire inputs if you are concerned about load imbalances. Overall: Great product, fast delivery, easy install, works.

Rated 5 out of 5 by from L padHi , I am very very satisfied with my purchase , I have installed them and getting exactly what I hoped to achive . I have two old power speakers that I wanted to convert to "monitors (floor monitors ) for a Country band . I was hoping to connect them to the new power speakers and be able to control the audio at the monitors ,which I can now do . I would also like to thank the lady who served me on the phone as she was very helpful and very proffesionnal at her post. Also ,the quality of these L-pads are excellent . Again , thank you ...Roger

Speaker L-Pad Attenuator 100W Mono 1" Shaft 8 Ohm

I am looking for a replacement L pad that would work in a pair of Optimus T-100 speakers. Do you have a comparable L pad?

Asked by: Truman52
If the driver that the L-pad attenuates is 8 ohm, this will work fine as a replacement.
Answered by: MattP

Can these be used as quick and easy attenuators for guitar amps?

Asked by: jrdworak
These are deisgned to be wired in line with the speaker itself, so if that is where you intend on installing it that will be fine as long as you don't exceed its rated power.

Why these over the 15W?

I only want to lower that upper two speakers of my cabinet. I have a 100 watt amp going to my 3-way system and want to attenuate the mid and tweeter. Could I use the 15 Watt L-Pads for that?
Asked by: tunaman
The midrange and tweeter will get a smaller percentage of the total power so it is certainly acceptable to use a lower power l pad in that application. a 50 watt, or even 15 watt should be fine for most users.

Can I use the 'L' pads on Piezzo's without changing the finale impedance of the total box?

Asked by: TJ Hechtle
Yes although in order for this to work there has to be an 8 ohm resistor in parallel with the piezo tweeter.
Answered by: MattP

Why capacitors?

What would be achieved by having identical caps of whatever value on either side of the l-pad? Would this be an attempt to control the voltage to the tweeter like a voltage divider?
Asked by: audioantique
That would cause it to behave like a tone control circuit.

all your l pads a 8 ohm??

I was going to use a bandpass crossover and a high pass on a neo 8 and neo 3 I wanted to put a lpad in line on the tweeter which is 4 ohms. Do you think it would be fine to use this 8 ohm lpad in my 4 ohm xover and speaker??
Asked by: puffah
For 4 ohm applications, use an 8 ohm stereo l-pad with jumpers between the sets of terminals 1, 2, and 3.
