Hi guys,
thanks for the input so far, I have built several subs and am not affraid of the ole table saw! haha, the sight of beige dust flying really gets one going in the morning
ut using an
The sub i have already is based on the "aerial sw12" its a cloe of that , but using an adire audio "shiva" 12" driver with 13mm xmax , when i researched this it seemed like it was upto the job, dont get me wrong, the bass is very smooth, and has output in excess of 110 db at 25hz, but its not enough, for me at least. The problem is that it bottoms (reaches its level of maximum excursion) well before the SVA's give a damn, and id just like to see exactly what they are capable of....
I have another sub cabinet lying around which is around 7cu ft tuned to 18hz with a 14" 1/16th" cut out ready for a 15" sub, I have tried a few 15's in there but same thing happens,
.
My room is 13ft wide , 9ft high ceilings and 25ft long, not sealed off as it turns at the end to where my Bar is, i estimate that the totall volume is over 4500cuft including the bar and small kitchen area. Could it be that the subs that I am trying just do not have enough xmax? as in they cannot move the entire volume of air as one unit to create the pressure loading im looking for before running out of electrical power handling?
The SVA's are insane!! They absolutely fill the room competently with bass, obviously not the real "low stuff" but my golly can they liquidise your innards with what they do put out! I have a full seperates system including carvers thx approved power amps (av-705 thx) bi amping the system and its very articulate, for the bass department I use P.A amps, which are rated at 1400wrms into 4ohm load, for the buttkicker, plus a 600wrms amp for the sub.
Hopefully this will give you a little more incline into the type of thing im after, requirements are....
1. flat as possible to 20hz ,
2. high power handling/output
3. Under 9cuft (they get extremely large after this!)
4. Ability to hit 120 db peaks
Sorry for what seems an essay, but I really am at the end of my tether here and am about to start to try building "bass traps" and the like!! urghhhhhhh
Thank you for your help and comments
P.S if anyones in Mexico , please feel free to contact and come and listen to them.
regards
Gary.
