But once I told her the weight her and I won't lie myself kinda though about just how heavy that is... And maybe just staying with the martycube.. The 2*2*2.
Would the bigger marty require more power than the smaller one?
How will the 2*2*2 with the SI 18" D2 compare with the SVS PB ultra? In terms of both sound quality and output.
Would there be a sound quality difference between the 2*2*2 and 2*2*4?
What type of ply should I get for the enclosure? As well what thickness? I heard PL premium is the best calking, how much do I need? What other materials do I need?
Mfusick -> I cant agree more, if you can provide me with some feedback on the listed questions/concerns.
Thanks a lot for your help guys!
There is not a good value amp that would do a single SI, other than an inuke 1000, but I think that is a bit underpowered, and it's not good value compared to the inuke 3000. Sound quality for bass is identical as long as you're not distorting, so the 2x2x2 and 2x2x4 subs will sound identical, other than the 2x2x4 going a bit lower in hz. Not sure about ply, I always build with MDF, depends what you have available. Ply might be better than MDF as it is much lighter. Check local lumber yards and see their best price, I think most wood will be fine.
In regards to your last post, you're right a 2x2x3 will fall right in the middle of the chart. I think it is pointless for 2x2x3, as the 4 foot length gives a better dimension for cutting 4x8 sheets so there isn't wasted wood. Not sure what your living room layout is like, but if you made it 2 high by 2 deep by 4 wide, you could use it as a speaker stand for your fusion 10's if you can fit it on the front. It will also look cool
Don't worry too much about weight, you're only gonna have to move them like once or twice. Just ask a buddy or two to help you. I find large subs are not too bad to carry with just two people, unless it's like a winding staircase or something. You can also carry the cabinet into your room and then mount the driver in right there. and remove the driver if you're moving if it's too heavy to move. 160 lbs really isn't that heavy though. Don't sweat the box designs too much they are all quite similar and you will only notice the difference in bass movies. You don't have to worry about your dog knocking them over though :P
The marty sub you keep referring to is a specific ported sub design LTD02 did, that has a specific cut sheet you can follow, these subs we're talking about aren't "marty subs" they're just ported subwoofers.
In regards to two drivers in one cabinet, you could do that, but it defeats the purpose of having two subs - being able to place them in different spots in the room to smooth the frequency response.
