BASSBOSS Questions
I only took one out for a birthday party in a restaurant. It rocked hard! My only concern was that since I played a variety of music certain songs were super heavy in bass and sounded amazing and some other songs sounded like they lacked bass so at times it felt as if the balance was off. Thinking I might need to get a processor to have a better sonically balanced signal for the subs.

Today I just set up a system with both. About to do sound check...

All of our gear is full processed to provide a very level and consistent sound across the frequency spectrum there are designed to cover.
Because of this, our gear illuminates the quality or lack of track quality in a very apparent way. Considering the HIFI quality of output and tuning involved with our gear, we advise no processing be applied to the channels supplying signal to the BASSBOSS gear.
Processing can affect reliability and subsequently may void the warranty. Additionally, I am confident user applied tuning applied to our gear would degrade the sound quality.

Variation between different tracks is typically a clear indication of a quality issue of the tracks themselves.
320Kbps MP3s are the minimum quality that I will suggest using. AIFF and WAV even higher quality (lossless) options as well.
Some record pools and bootleg media can even have doubly compressed MP3s. I have also seen folks edit or remix an MP3 and export the mix as an MP3, resulting in double compression.
Even doubly compress 320s are going to greatly suffer in the sound quality and dynamics department. Best practice is to export to WAV to avoid a second layer of compression.

As for the best practice on gear setup:
- if only one set of XLRs is dispatched to the system, hit the BASSBOSS subs first and the next manufacturer / tops second.
- you have a second output available, run the tops on one set of XLRs and the subs on the other. This will give you separate volume control and rapid adjustment to balance out the mix for lower quality tracks.
If you lack multiple outs, you could run the booth out to the tops and the master to the subs or vice versa, if booth monitor speakers are not being used.

Generally speaking, when mixing brands of speakers you could be encounting phase and time alignment issues that may be impacting the quality of sound. Also room reflections, nulling, comb filtering could also results in output diminishing cancellations.

I would check and adjust the LF roll off of the tops and the HF roll off the subs (EXO knob) to see if the output improves. You may have a gap between the subs and tops in the 80 to 100Hz area, which can be more apparent on certain tracks.

Additionally, moving the sub itself can improve issues caused by reflections and cancellations. Cancellations are more prevalent in left/right positioning, which lends itself to comb filtering. Sometimes a little bit of repositioning can make a dramatic improvement.

Subs clustered together in the center typically yields the best result, most output, and little to no comb filtering.

Ultimately, if the phase and time alignment between brand X tops and the BASSBOSS subs is identified as the most likely issue, a processor can help.
I am not a fan of the dBX Drive Racks. The Xilica XD4080 is a powerful processor featuring high quality D/A converters to preserve sound. This unit should allow the inversion of phase and delay adjustment to the tops. By ear/feel you maybe able to get it tuned well or to be proper, you could incorporate an RTA mic and measure output and get things really dialed in.

Another option would be a digital mixer such as the Behringer X32 Compact. The X32 would give you the ability to mix a show with a band/multiple DJs/multiple performers, manage mics more effectively, have discrete output for tops and subs, and process those outputs for phase and time alignment on the top.

At the moment, my money is on the quality of music and/or a gap in roll off between the subs and tops.

Naturally, I will be standing by to assist.

I was on that same situation when using the QSC KLA12 and BassBoss SSP118. Most of the time it’s around 80Hz to 100Hz. Like David wrote, either  those frequencies suffers from phase alignment or the roll off are different from the BassBoss. Different manufacturers have different delays on their DSP, these are more prominent with FIR filters. Try adding some delay on the sub, you have to use aux sub mix or if the mixer has a mono sum output. I still suggest using the same brand for ease of deployment and not to worry about the setup even if you have to use a different mixer.

The issue with the bass is real!!! We just aren't used to the whole frequency range being represented so well in gear. Also, bass is (as the slogan says) much more physically interactive with whatever environment you are in. Complaints or calls to the police have happened for me about 1/2 of the time i'm in a new place.

While any extra DSP isn't really suggested, i find that there are ways to deal with this by running your system through an EQ of some sort or by applying a high pass (low cut) filter on the output signal to the system. Only when needed of course and not as a normal thing. The bass being that heavy does not make the mid and high frequencies less hearable or present assuming your system is properly balanced and there aren't phase issues. As i'm using all BASSBOSS gear i've got no problem there.

Honestly, when possible i prefer the bass having an even heavier heft to it. It's just that in some cases you might end up with environmental issues like rattling or shaking or drinks falling or lights falling out, etc. So in those cases having a way to tone it down a bit to just below that point does a lot. Usually you only need to go just below that level where things shake and nobody complains more. Some rooms can be worse than others, but staying out of corners and doing a bit of pre-show testing to find the week spots would be good.

If you are using a digital board like an M32/X32, A&H, etc, you can also apply some targeted frequency cuts, but you'd want to only do this minimally so as not to throw the whole sound out of balance.

Just some thoughts!
