I've used for a year, c is the price of housing are really good quality, it is important not to confuse the MB and SB SB are much larger in my face less deep it goes down too low moin frequency t for trying the range c wharfedale far is that I prefer day, although he did filtr no problem maintaining regimes lev. by coupling them by 4 the result is really satisfying. When I bought j avai choice and if I still had the choice I had to do it again because after the lixc J had a system m FROM HOME JBL PRO 400 with 2 mp 415 mp418 and 2. The heads were astonished my the sub has more than 2 times the price of the Wharfedale does not really worth the blow and I then resold.
