No offence to any JL fans.
I bought an alpine Type R sub (350 RMS) from a friend on a reasonable price and compared it to JLW7.
Not a lot of difference in terms of SPL (both of them are shaking my car), however I felt that sound quality on type R is better than W7.
I wonder what is the point of spending £500 on W7 (or £300 for used one) if any other decent sub on a 1/3 - 1/5 price can do nearly the same job.
Away for 4 weeks. PM only if its urgent.
