Hi:I am interested in building a smallish(2-21/2 cu ft bax) guitar (lead) speaker for my son. I had thought of either a bunch of small drivers with a low Vas in series parallel to obtain a large radiating area and high combined efficiency or two high output 10 inch or 12 inch drivers. I would like to get the efficiency as high as is possible and the cost as low. For my son volume is the prime concern you know, loud is good louder is better too loud is perfect. Any good suggestions? I did find a 4 1/2 inch MCM driver #55-1200 which is 94 db efficient and has Vas of 0.14 cu. ft. cost $8.00 each. Sixteen of these would be about 106 db efficient.
You could also check out Kendrick amps. Gerald has a 10" alnico. Probably costs near what 16 of those MCM speakers will cost and will sound like a guitar is supposed to.
Celestion 12 inch speakers are the way to go 2x12's.
For PA i Use JBL Pro . But for guitar celestion is the way to go.
Use the same model as the ones that come from Marshall 1960A or 1960B
Cabinets 75watts a speaker.Use Celestion Greenbacks 25watts a speakers
if you PA the cabinet with a mic. These are what the pros use.
I have to agree with Dman. True guitar drivers are the way to go. Most smaller guitar cabs are open backed anyway. They are made to take the hammering of a plectrum on metal strings. You don't lose a lot to bass cancellation with an open back when low [guitar] E is about 82Hz fundamental and probably 75% of the energy is from higher harmonics anyway. I often see Eminence speakers widely marketed. I believe they produce custom orders for amp-makers but I still wouldn't want them.
Celestion are a safe bet; JBL Pro, Electrovoice, Altec, Cerwin Vega are "RollsRoyce" but not necessarily better sounding. Others are a mixed bag. Note how high fs is on these linked drivers. These are not better in sealed boxes.
Thanks for the backup on that speaker issue! I'm getting tired of hearing amps that sound like skeletons screwing on a tin roof during a hail storm! Hope the amp has some tubes in it or we're really in trouble!
What style of music is he into. From the "loudness" comment, I would assume hard rock with lots of distortion. If so, several small speakers are going to sound like crap because of teh high frequency content in that signal. Better to stick with a 10" or 12" if thats the case (most guitar 10" and 12" speakers are healthily over 90db anyway!).
Cheers and good luck
Dman (the only bass guitarist in my locale who DOESN'T have hearing loss!)
