BiggerIsBetter Posted February 9, 2006 Share Posted February 9, 2006 They certainly can. I had been a big fan of Phil Jones designs and have several of the Platinum audio speaker, which go lower with their 5 inch woofer than my Corns do. Still, given the tradeoffs involved, I'll take the large woofer please. Quote Link to comment Share on other sites More sharing options...

artto Posted February 9, 2006 Share Posted February 9, 2006 Yes they can. SWR made a pretty nice 8x8 cab at one time. However, typically, these bass rigs today are used primarily as stage monitors for the musician. In other words, they need to cut through the stage sounds, but dont have to throw the sound very far out into the audience. In my experience playing bass, there is no substitute for moving air, a large column of air, and small drivers just dont do it for me. Unless its an acoustic-type gig (minimal amplification) I always bring at least one 15 along. This small driver crap came along when all the pop and slap and two handed tapping became popular on electric bass because you needed the treble and transient attack to get that sound, hence the further development of also including tweeters in bass rigs. Another caveat of the smaller drivers is that since you must use more of them to move an equal amount of air as the larger drivers, you end up with way more magnet structure, and consequently the cabinet weight goes WAY UP. My 1x15 are far lighter than the same size cabinet in a 4x10 for instance. If youve got a roadie to haul that stuff around for you, great!! But at my age, Im done carrying that kind of crap up three flights of stairs for a $50 gig. [] Quote Link to comment Share on other sites More sharing options...

rockbobmel Posted February 9, 2006 Author Share Posted February 9, 2006 I heard a guy with the 16 driver bottom and a 8 driver top with a vintage SVT. It sounded way killer. These boxes are extremely heavy and not for the giging city musician that has to haul stuff night after night. That's what the new neo cabs are for. A Walter Woods (7lb) 1200 watt amp and 2 1-12 neo cabs can be made in one trip. Quote Link to comment Share on other sites More sharing options...
BiggerIsBetter Posted February 9, 2006 Share Posted February 9, 2006 I would expect them to sound great. They look ike the same woofer he has been using for years. The platinum audio trios I have use 2 per side, with a 1.5 way crossover. With around 200watts in a small to mid size room they can move enough air to sound very good. At lower volumes, the life is sucked out of the sounds.....I'll keep the clunky old cornwalls 15s..... Instead of asking IF it can be done, the better question might be WHY?????

artto Posted February 9, 2006 Share Posted February 9, 2006 "At lower volumes, the life is sucked out of the sounds....." Exactly right Bigger!! IMHO, one the real acid tests for high fidelity sound reproduction is not how loud the damn thing can play, thats a piece of cake! The real question is how much resolution of timbre, dynamics, and sense of space can it reproduce at the lowest levels? Quote Link to comment Share on other sites More sharing options...
Zene Posted February 9, 2006 Share Posted February 9, 2006 Even the good Dr. Bose beat that by a country mile for it's time, let alone the "Sweet 16" from the 50's (?). One of his first experiments was a large 1/8 sphere segment placed in corner with bunches of speakers. College grads did most of- the work and he got rich, smart. Couldn't help but make bass. Even though he was after omni at the time. Pic should be available somewhere, it's very interesting. Someone should try again. In fact .....Hmmmm, pencil? I have NSB's galore and 15 pair of paper wizzer cone 6 1/2 car speakers. Zene Quote Link to comment Share on other sites More sharing options...
D-MAN Posted February 9, 2006 Share Posted February 9, 2006 ...and as an added bonus, these multiple driver puppies also produce BIG IM distortion and display a real bad polar response... As for its overall frequency response, well... got an EQ? You're gonna need one! DM Quote Link to comment Share on other sites More sharing options...
DrWho Posted February 9, 2006 Share Posted February 9, 2006 I'm not sure how he claims a "faster cleaner" response (aka, better impulse response)...It takes at least 9 of those drivers to match the surface area of a typical 15" driver (comparing effective acoustical diameter...not the width of the frame). Think about it, for the same Fs and system sensitivity the sum total of the suspension, moving mass, and electrical properties would need to be the same as a single larger driver. In other words, he has achieved more power handling at the expense of cost and weight in a system that is excursion limited either way (making that extra power handling kinda useless). And then there are issues of comb-filtering, narrowed on-axis response, and issues from variations between the drivers (no way in heck all 32 of those drivers are going to be operating in an identical fashion). (but it's not quite an apples to apples comparison because the smaller drivers are going to have more moving mass per surface area, which then requires a change in the suspension and motor) The only real purpose for adding multiple smaller drivers instead of going with a single larger one is to make the cabinet size smaller (which reduces cone excursion which then allows one to take advantage of the extra power handling). I don't see him making the cabinets smaller though, lol. I do agree that cone deformation is an issue on the larger drivers - and that is the only reason we don't see as many 18" drivers on the market. But I can think of many way cheaper methods of addressing that issue than throwing on more motors per surface area. Anyways, I don't mean to bash something without hearing it...all other factors aside, do these things really sound better? I'm yet to hear anything that comes close to the hartke aluminum woofers...oh so sweet Quote Link to comment Share on other sites More sharing options...

sfogg Posted February 9, 2006 Share Posted February 9, 2006 " And then there are issues of comb-filtering, narrowed on-axis response," Depends on how high up in frequency they go. If they are limited to bass range it probably is not an issue as the wavelengths are so long. Shawn Quote Link to comment Share on other sites More sharing options...

If they are limited to bass range it probably is not an issue as the wavelengths are so long. Well a lot of bass rigs are pushing as high as 10kHz nowadays - though most of that is noise. But I'd say most rigs need to be solid up to at least 3kHz, which is a bit beyond the capability of a 15"/18" woofer which is why a lot of guys will run dual/quad 10's. (though my favorite rigs always had a single 15/18 and a dual 10 top biamped with independant crossovers). Quote Link to comment Share on other sites More sharing options...
