my subs need 0.75 cubic ft. i have a box from older speakers that measures 1.00 cubic ft. if i used this box on my subs would the difference in size be noticable, any effects, anything? i am not sure it is only 0.25 cubic ft difference. thanks

Thats a fair difference, but you can use box stuffing to make the sub think the box is smaller than it really is.

Your subs might not hit as hard but it shouldn't be that bad. Many times companies will say they need less space than they actually do. This way you are inclined to buy more of their product to fit in your car because you'lle have extra space.

Actually, fiberfill is supposed to make a speaker feel like it's in a bigger (NOT smaller) box by slowing down the sound waves radiated from the back of the speaker to the back of the box. Ive made boxes for my cars for 8's, 10's, 12's and 15's in my 9 years of installing. For 10's designed for a 0.75 ft3 box, going up to a 1 ft3 box will make your subs sound muddy and distorted, even at low power. Generally, the manufacturer's range has the smallest box size designed for SPL (maximum sound pressure level, but over a very limited frequency range) and the larger box size with the ability to produce output with low power amps. Attend any national or regional soundoff, and you will see the majority of the SQ (sound quality) winners with subs in enclosures about 10% larger than the MIMIMUM manufacturer recommended size. This size gives the best balance between loudness (the reason you got the subs) and sound quality, and this will make the difference in whether your subs will sound like 1-note garbage or as powerful, punchy bass with distinct bass tones that actually will impress others. Box size does matter.

btw, fiberfill is used as a supplement to a box design, not a fix. Using fiberfill to correct an incorrect box size is analagous to using a thicker anti-roll bar to fix a poor suspension setup. Ever see fiberfill in a plexiglass enclosure? I would just suggest using a box of the right size, make sure it's completely sealed, especially around the woofer and the terminal, using rope caulk, f necessary to ensure it's airtight. Another option is to spray the inside of the enclosure with a light coat of sound deadener to reduce in-box resonances, and avoid perfectly cubic boxes and not have any panels more than 2x the length of another to avoid uneven frequency response. That's probably more information than you need.

IMO i'd go with a bandpass box with 10s I hae 2 alpine 10s in a bandpass box with only 600 watts and it hits harder and louder than many of my friend 1500w plus stereos!!!
