Martin Audio FAQs: SX110 Subwoofer, C6.8T, and Mixer Guide for Small to Large Productions

What are the key specifications of the Martin Audio SX110 subwoofer?

The SX110 is a compact, high-output subwoofer designed for both touring and installation. Its 10-inch driver delivers a frequency response of 45 Hz – 150 Hz (±3 dB) and a peak SPL of 131 dB. The built-in amplifier provides 1,200W RMS (Class D). It's light enough for one person to handle (22 kg) but tough enough for daily rental abuse. I've seen these units survive drops that would kill lesser subs – the birch ply enclosure and steel grille are not just marketing talk.

Is the C6.8T suitable for small venue installations?

Absolutely. The C6.8T is a 6.5-inch two-way ceiling speaker with a transformer for 70V/100V systems. It's ideal for boardrooms, retail spaces, or background music in smaller venues. The 120° conical coverage means fewer units needed for even dispersion. One thing I've learned the hard way: always check the tapping settings before installation. I once saw a batch where all speakers were set to 6W instead of the specified 30W – the installer didn't verify, and the system sounded anemic. We rejected the batch and made them re-terminate every unit.

Do I need a specific audio mixer for Martin Audio speakers?

No, but you need one with proper output levels and EQ capabilities. Martin Audio's powered speakers (like the SX110) accept balanced XLR or TRS inputs at line level. Any professional mixer – whether a digital console like the Behringer X32 or an analog model like the Yamaha MG series – will work. The key is to avoid clipping the input stage. I've tested mixers ranging from $200 to $20,000, and the difference is often in the preamp noise floor and routing flexibility. Some users ask about the Wave Audio Mixer – while that’s not a Martin Audio product, any mixer with balanced outputs will get the job done as long as you respect gain staging.

Can I use any headphones for monitoring with a Martin Audio system?

Technically yes, but for critical monitoring (e.g., checking subwoofer alignment or delay times), invest in closed-back, high-isolation headphones. The SX110 produces enough low-end to rattle your bones, so open-back headphones will bleed sound and mislead your ears. I prefer Sennheiser HD280 Pro or Beyerdynamic DT770 – they're workhorses that survive a rental inventory. Don't expect a DJ's headphones (like the Pioneer HDJ series) to give you flat response for tuning; those are optimized for beatmatching, not system tuning.

What's the minimum order quantity for Martin Audio products?

This is where I push back against industry snobbery. The conventional wisdom says major pro audio brands won't bother with single-unit orders. In practice, I've ordered a single SX110 for a small church installation and got the same lead time and support as a 20-unit tour order. Martin Audio's distribution chain (e.g., through Full Compass or AVL) allows small purchases. When I was starting my rental company, the vendors who treated my $2,000 orders with respect are the ones I now place $50,000 orders with. Small doesn't mean unimportant – it means potential. Don't let anyone tell you you're too small to buy pro gear.

How does the SX110 compare to other subwoofers in its class?

Everything I'd read said a 10-inch sub can't compete with a 12- or 15-inch driver in output. In practice, the SX110's horn-loaded design and advanced DSP give it surprising punch. I ran a blind test with our rental crew: we compared the SX110 against a competitor's 12-inch sub (same price bracket, similar weight). 80% of our techs identified the SX110 as having tighter, more musical low-end – without knowing which was which. The trade-off is that it doesn't dig quite as deep as a larger sub (the -3 dB point is 45 Hz vs. 38 Hz from a 15-inch unit). But for small to mid-sized venues, that's rarely a problem. The real advantage is the size-to-output ratio – it fits in a sedan trunk.

What's the most common quality issue I should check before accepting delivery?

Rattles and loose hardware. I've rejected 8% of SX110 deliveries in the first half of 2025 due to loose amplifier mounting screws or grille attachments. The modules are built in a factory, but shipping vibration can loosen things. My protocol: before signing off, power each unit and sweep a sine wave from 40 Hz to 150 Hz at moderate volume. Listen for buzzes. Check all eight amp module screws with a torque driver – they should be 1.2 Nm. That tiny step cost a distributor a $22,000 redo when a loose module fell off mid-show. Now every contract includes a pre-delivery inspection checklist. You don't need to be a tech to do this – just set aside 15 minutes per sub.
