sometime in the early to mid 70s, a couple of guys started playing bass without the use of cabinet grill cloths on their speaker cabinets. and… it looks awesome. plain and simple. it became more of a thing i think as time went on, i think. or maybe in the 80s and 90s. there’s a purpose to grill cloths, to somewhat protect the speakers, but does anyone around here ditch the grill cloth on gigs?
I also like the look of a cab without a grill cloth covering, but (as I have learned from experience ) want something covering and protecting the drivers. I reworked this Ampeg unit with new Legend BP102-4 drivers and decided to go with metal grill covers rather than replacing the stock cloth. For me, it's not worth having a drumstick or other projectile damage an already fragile component.
Self proclaimed speaker geek, I like seeing the drivers exposed. Watching them move is neato..... especially nifty aluminum coned units.
I don’t like grill cloths either, but do want some protection for the speakers. Metal covers look good to me, especially those “per driver” covers. I feel like transport and setup/tear down are the times of high risk. Once the stage is set and wired you would hope your band mates could avoid busting up one or more of your speakers. You would hope. I use metal covers.
Grill cloth doesn't do much to protect speakers in case of a traumatic event: e.g. drunk dancer careening into your gear. Metal grills, yes. Audiophiles love to have the grill cloth off their home stereo speakers, arguing that it removes that tiny bit of muffling of high frequencies that the cloth might produce—but realistically, I think they like to look at the speaker tech they've paid such money for.
They both have their down sides. I’ve had stuff poked through holes on metal grills. Never had someone put enough force to damage speakers on a cloth grill but him sure it’s a problem in energetic bands and venues.
this made me think of keith moon stabbing holes into john entwistles amps (which has never happened), and then it made me realize… the who probably have THE most energetic guitarist, front man and drummer, yet john entwistle is perhaps histories most non-energetic bass player. i bet by the end of every show there’s a little dimple in the stage where he was standing. not related to anything at all, but that’s just sort of funny.
Sturdy grill coverings do provide protection when done right. Exposed speakers are an invitation for damage, especially with pets, kids or simple accidents.
A grille cloth can act as a highly focused filter. Long waves can pass through whereas short waves are attenuated. it’s called a cloth because it scrubs the combined waves emanating from the speakers, filtering them into separate time aligned signals. The grille cloth also reduces reflected waves into the speakers, attenuating back EMF in them. Believe this, you read it on the interweb.
Just my opinion, with speakers running $200 bucks apiece and up, and knowing what can go on at a gig where (ahem) people are being people, for me taking the grill off is a non- starter. My current cabs have grills that are of a steel gauge heavy enough one could “grill” on them. No joke. And they will stay on there until I have to recone, replace them, Or I’m looking at the wrong side of a lawn.
A properly tuned grill cloth can block the thetatron brain waves of most guitarist brains, preventing lenticular overflow of guitarist energy from spilling over into the bassist's neuroacousstic spacetime. In extreme cases, however, a grill cloth may cause a buildup of fromular standing waves, resulting in overheating of the harmonic cortex and, in extreme cases, a brain explosion.
Omnidirectional high frequency damping can be canceled out with eq (or just baked into the speaker design) but the diffraction of HF sound off the grill frame is harder to undo. Non-issue for a bass cab. For a gigging cab the trend seems strongly towards metal grills, even if someone's not trying to kick in your woofers, they're just easier to clean.
Went without grill cloth on a couple of 1x15 cabs I built in the late 70's. It wasn't my intent, it was just the last step in the project that I was going to get around to but never did. After a while I came to appreciate the mechanical beauty of a visible speaker, but at the time metal grills were harder to come by than cloth, so I just went without any covering. Never had an accident. In fact, the only time I did have someone accidentally poke a mic stand into one of my cabs was a 2x15 that I did have covered with a fabric cloth (not standard reinforced speaker grill cloth).
