Hello everybody, I am a new member of the forum but an old reader. I have become a member because I now have the opportunity to do some DIY projects. What I have in mind is to build a pair of av-1s w/ sub and then expand to center & surrounds later. I have a strict budget which is why I need to build a good sub for a dirt cheap price. What is have in mind is to build a sub with the following parts: Blueprint 1201 & partsexpress 120wplate amp. These are the cheapest parts I have come up w/ to get decent bass. I am pretty sure I haven't found the cheapest but this may be a good start. I do have in mind an alignment. Sbb4 vented in parallel wattage. I think I may have found some good measurements using winisd pro, but I was wanting to ask if any kind-more-experienced-soul could run the numbers in winisd pro for me and tell me what the optimal measurements would be. If any takers - Thanks In Advance.
