depends on which dd though. the solo x is no joke. it is very powerful and loud. it just don't sound that clean according to alot of people. i personally think the solo x has a decent sound to it.
ok l have zx2500 andl am going to buy another but for now l have s12l7 in 3.25 cf ported l dont know what l am going to buy l like kicker but l wish at least 150 dbs
ive heard the 18inch solo X briefly, sounds good on the lows but thats it, no joke. i heard it in a walled enclosure around 12 cubes or so at about 40 hz. it was absolutely ridiculous. probably the loudest subwoofer i have heard personally. there is no wayi would buy one though, DD is farrrrr better. solo X is not sufficient for daily driving. way to many electrical upgrades, and you may be the loudest around the sound quality is terrible.
157 is possible. but the box would have to be optimized for just one note and it would still be difficult. but for a normal 35HZ tuning or anything of daily driving just wont hit 157 with one 12, even if it is DD
well doktah.....if you read down a couple of more posts, i did come back and said "depends on which dd though". meaning it is possible.
he was very vague by saying dd 12. so you think any dd will have a good shot at 157? maybe i should sell my subs and just get a dd 3512 so i can hit 157. lol.
3512 wont hit 157 i have tried everything with this sub and the loudest i got was 146 which is great for one 12" i did have way more power than suggested for it but the sub took every bit of it. in a crx or another small hatchback with a great install im sure 1 9512 could hit 157 or close to it. depends on too much but i believe it could
btw doktah. i believe the 9917 is a 18 inch sub. if thats the case than it has more cone area than 2 12s. just thought i throw that in there. not trying to be a d!ck or anything. lol.
do a bigger box with 4-6 6" aeros tuned to 45hz it will be gotta be a great install
