    Hello diyma! I've been doing research on cabin gain in vehicles and there seems to be all sorts of different information on the effects of the volume levels of certain frequencies in smaller spaces where the wavelength of the frequency is longer than the space it is occupying. Apologies if I am...

    Does anybody real world experience with the 8ndl51 ported and in a vehicle? What was your volume and port dimensions and results in your specific vehicle? Finding firsthand user accounts of this woofer in relation to a ported box have yielded me little to no useful information. The only...

    What a surprise! I just modeled some winISD controllers to see which would be most suitable for my project: I want to run an active 3-way configuration, and for Mid-Bass (with range 63hz - 315hz), I need speakers that work well in a small box. Only .2 ft3, since it is the space available under...

    I´m researching about wich Mid-bass speakers to use in my 3-way active setup. They will go under seat because I don´t want to deal with doors rattles anymore. That´s it. The box must be small (.1 - .15 cuf t) to fit under my front seats. Up to now, the winner hands down is the CDT M6+, wich...

I was told by a buddy who owns an audio shop that this sub is best in a ported box, however upon plugging all...

    I recently purchased a Treo SSX 15" woofer that came with a crappy box so I want to make a new one but I have no idea how to calculate any of the port area things and the calculators do not work with the space in my trunk. The manufacturer recommends 3.5 cb/ft @ 29.4 hz with a 50sq/in vent...

    Hello all, I'm trying to decide on the best subwoofer for my particular installation. I already own a pair of Audison AV10 Voce subs, but I'm flexible about upgrading to a Thesis TH10 Basso if it will improve SQ. My subs are currently in a sealed enclosure, aimed toward the rear of the trunk...

    I'm thinking about making a center console enclosure for 2 6.5" exodus anarchy speakers and crossing them over for just sub duty. I can't seem to find any ported box recommendations for these speakers. I have read that sub down port forward is best for center console configurations. I'm not sure...

    Hello again, sorry if this has already been discussed I tried searching but couldn't find any topics like this. I'm trying to get the most and lowest bass out of my 02 civic using 3 12" subs ported. My current idea to get the best transfer function possible, is have my 12" subs facing the rear...

    Hello I am in the process of trying to build a box for (4) diamond audio d110d4.2 subs I have. I believe I need a 4.0 cu ft box which I believe the dimensions are *(W x H x D): 33" x 16-1/2" x 21" The only thing I do not know are the dimensions of the slotted port and how far away from the...

    i like sq over spl anyday. but i still want my system to get earsplitting loud which i doubt will be a problem. my main question is which type of subwoofer box will sound the best and get the most vibrations into my body?:D i was thinking about either a simple sealed enclosure or a 30hz tuned...

    I'm looking for sealed so the bass is tight and punchy but want it to do low low bass as well. Setup will be purely for SQ. Thanks for any input.

    Hi there! I got hold of a pair of 6x9" speakers a few days ago and now I plan on putting them into boxes to be used in my study. :laugh: Which type of enclosure should I be looking at? Usually the comments are pretty mixed when it comes to ported vs sealed, and especially for these type of...
