@kenjit i agree for 100% , the open baffle desigh is made for folk who is looking for something unsual , The speaker bulders using old idea like new , Nothing magic . Depend of baffle size , sound wave from front cone meet wave from back and kill each other, The best open baffle is infinity size baffle. For size 20-25" you did not get low base, If you dont care about listen as is, If not --get sub , NO BENEFIT
