Is A Crossover The Way To Go With Two Subs?
 

I am thinking about adding a second subwoofer to my main system. If I do so, should I be also getting the JL crossover? I have read often that it can be difficult to properly dial in two subwoofers.

IMO - The Cr-1 would make it easier. :D:D:D

I would agree the CR-1 would definitely make it easier. However, if you only intend to use the subs at very low frequencies say below about 50 Hz, you might be okay with simply using the respective sub controls. I guess it really depends on what if any issues you are trying to solve.

Two Articles from JLAudio about adding multiple subwoofers:

Both excellent articles. The first explains, at least to me, why I have never heard a system with subs just hooked up to the main speaker terminals sound correct.

Is A Crossover The Way To Go With Two Subs?
 

Ivan has a few systems that feather in subs without crossovers and let’s say they work well, very well.

One with his Aida’s and one with his Strads. The JL subs are set below 50Hz.

Thank you! I’m still also trying to figure out if I really do need two. With one, I have it placed in between the two speakers. I haven’t decided exactly where I would crossover, but I am leaning towards the lower end of the range versus 80 Hz.

You need two. I started with one and the second made all the difference. Really really much better result.

"Simply connecting a subwoofer to existing main speaker (or amp) terminals is the worst possible way to do this. Everything scientific and acoustic about this method is wrong, from the additive delay issues, to the back EMF of the main speakers affecting the low frequency signal. However there are plenty of people who simply do not understand correctly integrated bass, and they will be reasonably happy simply sticking another box on to their system without regard to timing, phase and frequency issues, and they will think it sounds “ok” or “good” and for those people it does not really matter."

"But back to our home / HI-FI / 2-channel / Audiophile / Surround Sound systems: There is only one truly correct way to “add a subwoofer” to a system in a controlled listening room situation: you must correctly cross over the two sealed cabinets (in the frequency domain) ; and their timing (the phase domain) must be correct. Any other method will lessen the focus and clarity you have tried so hard to preserve."

I recently had to reinstall two of my subs. Followed the articles to do the install. I have a digital preamp that allows me to do the time delay and crossover frequencies. Works beautifully.

That’s a rare luxury. I have my two channel system running full range, and the same speakers integrate with the HT with proper delays and subwoofer integration. Best of both worlds.

I really like my MEN220 rather than a typical crossover.

I get the benefit of setting specific crossover points and delay etc...BUT as a bonus the room correction for the balance of my system is amazing.

Two great gadgets in one!!!

Yes.

You will get a much better way to control the over sound and punch with one and especially 2 subs or more. If you can afford it look at the Cr1 or a DBX system.

Night to day improvements are around the corner.
