I believe only 2 can be linked wirelessly, as it creates a left/right stereo pair. If you needed to link 3 or 4 of them, you'd probably have to daisy chain them with XLR cables instead.

@BrianDiener thanks

Yes you can. I just tested this. The Bluetooth volume isn’t controlled by channel two, it’s only controlled by the main volume and your device’s volume. Channel one and two are isolated, so you can use two mics + bluetooth all at the same time.

Thanks man! How are you liking yours?

Whether or not there’s a market for it depends on your area and how much demand versus competition there is. In addition to how and where you market yourself. Offering value is important, but being the cheapest option isn’t a sustainable business practice in the long term, so have a plan for growth. Clients will pay a premium if you’re genuinely good at what you do and have some experience. “Small to medium events” is a bit subjective. Everybody has a different definition, so put it in terms of total audience size, then spec a system for the largest number of people you expect to encounter. The bigger the investment, the longer it takes to be profitable, so it’s ultimately a business decision only you can make based on the variables. That said, I think most sound guys will agree it has been pretty busy the past few years. So that’s already working in your favor!

:(

update: this thing was a steal at this price and holy moly it slaps for a 10”

Thank you! Yeah I still can't get over the amp draw. These are so efficient considering the output power they produce. It's a lifesaver for large venues with limited power availability.

Hmm that doesn’t sound normal. Even if the speaker is limiting, the only noticeable change should be a slight dip in volume. When it happens, does it crackle out of both speakers or just one? If it’s both, then the problem is probably elsewhere in your signal chain such as a mic clipping. If it’s just coming out of one, I’d try switching your XLR cable from channel A to channel B and see if the issue persists. Process of elimination from there.

Some very good questions indeed. It's a long answer that has to be prefaced by a few points: 1. QSC LA108/LS118 are both single woofer boxes. Whereas the SRX906LA and SRX828SP are both dual woofer boxes. 2. Either system could handle this situation and be tuned to sound good without too much trouble. But as far as which would be better overall? Well, on paper, these are compelling comparisons! We can take VRX out of the equation first. VRX is a much older box than SRX800/900. Even though it's still priced high, both L Class and SRX products sound objectively nicer than VRX. That said, since you're planning a deployment of installed subs, the single vs dual woofer dilemma in the line arrays becomes less of a concern since you're using them mainly for highs. What's going to make a huge difference is comparing the LA108 HF driver to the SRX906LA HF driver. Quoting directly from the manufacturer websites: The LA108 has a "1.75-inch compression driver with Polyimide diaphragm". The SRX906 has a "1.5 in exit neodymium compression driver with 3 in voice coil". So that matchup of single HF driver versus single HF driver would be quite a showdown. For the lows, it's hard to say if four LS118's or two SRX828SP would perform better. The specs rival each other pretty closely. If the LS118's are paired two and two, there should be a +3dB coupling effect that will increase the maximum SPL from 138dB to about 141dB. Which happens to be the same max SPL of the SRX828SP😂 Do you need the option to do cardioid subs to prevent stage bleed? That could be a deciding factor for the QSC option. Do you need Dante support? That could be a deciding factor for the QSC option. Do you need to hit the lowest possible sub-bass frequencies in a church environment? That could be a deciding factor for the JBL option. (The SRX828SP is rated at 29Hz versus the LS118 at 35Hz.) Do you need 1º splay angle increments for your system design, or would it be achievable using a combination of 1.5º, 6º and 12º? Paper comparisons only get us so far. The best comparison is closing your eyes and listening. So if you can get demos of each system, that would be ideal!

Let in ad the SRX 828sp is no way close to 141 SPL it's just a number. I own db technologies s30n and the SRX 828sp both rated at 141 SPL, and you need to have 2 828sp to equal 1 db technologies s30n.

Well it's the official number on JBL's spec sheet, but max SPL and max _constant_ SPL are two very different things. The former looks better for marketing, whereas the latter is more representative of real world results. So I have no doubt the DB Technologies sub is capable of higher sustained output than the SRX828SP. Especially since the voice coils are 4" (compared to 3" on the SRX828SP).
