I have an Epik Valor on order http://www.epiksubwoofers.com/ValorSpecifications.html, but am still considering the F15 in black oak. It seems as though the two are similar, but the Rythmik having better bass management features. The Epik reportedly has very good output for a smaller sealed SW and is considered as good as the HSU 3.3 with music.
The Epik is $549 where as the Rythmik is $899. I live 5 minutes away from Epik and it would be very conveinent for me.
I am about 50/50 HT and music. I am currently using a Mirage Omni S12 which has been mainly good for me.
What would the pros and cons be of both?

Thanks
