Does anyone make a preamp with a subwoofer output?

Many active subs have high and low level inputs, as well as a gain knob and frequency rolloff settings, which gives you plenty of flexibility.  If your sub has hi-level inputs, you can run it from the speaker outputs of your amp.  I actually prefer the way my sub sounds driven from the amp vs driven from the preamp line level outputs.

knotscott,


You are correct, I can adjust the slope and output on the subwoofer. I’m looking to be able to adjust the slope on my speakers. My speakers are Acoustat Model X’s and their design (three wire) I can’t run high level inputs. That’s why I’m asking about if there are any two channel preamps that can do what my HT receiver can do.

My Topping pre90 has RCA and XLR outputs. I run a KEF KC62 sub with the RCA outputs. The XLR’s go to Benchmark AHB2 monos. The Topping pre90 is a very neutral preamp. My Benchmark HPA4 preamp which the Topping replaced also has the same RCA + XLR output capability.

Another option is insert an active subwoofer crossover to your existing preamp, like the JL Audio CR-1 which featured adjustable crossover point and 12/24dB slopes.

yy,

That’s basically what I have set up now, running the speakers full range and the sub comes in at 70 hertz.  The panels on my speakers don’t like certain sounds, like the heart beat on dark side of the moon or really deep organ notes, so I want to be able to slope off the bass going to the speakers and let the sub take over.

imhifian,

 I started to go the dsp route and thought that maybe there was an all in one solution where maybe I could end up with a better preamp as well as the same controls I get on my HT system.

Does anyone have experience with this?

This should do just what you want:

This is the review of the Icon4 PRO which allows you to use high and low pass filters for your mains and subs. The reviewer is a bit loquacious (wordy) but he had the same problem as you and found this to be the best solution.

Here is the site for Icon:

The Icon4 PRO is only mentioned at the bottom of the site as coming soon. 

All the best,

The best and most cohesive way to connect your subwoofer is using high level outputs from your main amp. I have tried line level and speaker level many times and have always found tapping off the amp to be the most natural sounding of the two options.

ozzy62,

I have Acoustat Model X speakers that come with their own Servo amps that have three wires going to the speakers, not two, so I can’t take the high road.

Thanks

nonoise,

 Is this what you’re talking about?

You we’re right, the author of the 6Moons review rambled a bit.

Thanks.

Thanks to everyone who replied,

My house was broken into the other day and getting some damage repaired has taken way to much of my time!
