    You have 2 options, and rigging an RCA cord to the subwoofer inputs is NOT one of them. 1) Buy active subwoofer 2) Get something to serve as a subwoofer amp. You can use an old stereo receiver.

    Capacitor damage

    Hook it to an ohm meter to confirm that it has infinite DC resistance. If so, it is safe to use.

    Phono Preamps...?

    Radio Shack (of all places) makes a small battery powered phono preamp that is dead quiet and highly regarded by some hardcore audiophiles, and its cheap. Even if your receiver does have a phono input, you might want to give this a try (but don't use it with a phono input or else you'll have 2...

    What is "The Weakest Link"????

    Its only in the chain for the sub. It works in the digital domain, and microprocessors are cheap electronics. To know if it would help you, you need to plot pure sine wave SPL against frequency from about 20 to 100. If thats nice and flat at your favorite listening position, then you don't need one.

    bi-amp x-over

    Sorry, you cannot do this. No line level crossover, no biamp.

    What is "The Weakest Link"????

    The answer is obvious and has already been mentioned twice- a BFD. This upgrade will cost less than some of you cables and have a huge impact.

    Make it easy like SVS

    I would take issue with this statement. Neither dynamic range nor output (above 80 Hz)are really related to the box volume, which is the only difference between towers and bookshelves (presuming woofer diameter is the same). Book shelves exist that are flat to 60-70 Hz, and the sub takes care of...

    Do I need equalization with this frequency response?

    Your way better off than most. I would be satisfied with that for movies. Bassy music would benefit slightly by flatening that out. I assume these are pure sine waves ? Warbles will make the curve look better than it is.

    need help wiring three way crossover from PE

    "C" stands for common. So, the "in" and one of the commons go to the posts on the back of the box. Make sure you know which post goes to C for each box so you don't end up with a phase problem. Then the other three commons go to your drivers (one each) on the unmarked lugs. The marked (or +) lug...

    Veneer questions

    The best way is to veneer before cutting the recess, but it is too late for that. If your through hole and recess have already been done, and you have a rebate bit, then veneer over the hole, rough cut the veneer with a sharp knife, then run the rebate bit set shallow to trim the veneer. If this...

    Veneer questions

    I don't think you are going to find nice rosewood in 4x8 sheets. In fact, the 4x8 sheets are mostly ordinary stuff- maple, cherry oak etc. The best place to purchase interesting veneer by far is Ebay in my experience.

    New to Projectors

    Better than decent I would say. It looks like real HD even though some pixels are missing. If the budget won't allow a 1280x720 machine, then the 4805 is an option. Sports look great.

    Complete DIY System- Progress Pictures

    I assume this is for the sub which is a single mono signal. The Yamaha receiver has a sub out RCA jack. Plug a single rca cable into this. You can use one half of a pair. Plug the other end into the adaptor, and plug the adaptor into the carvin input #1. Depress the bridge switch. With this...

    Complete DIY System- Progress Pictures

    To beat the dead horse, 2 tweeters bad idea. They will step over each other, and even only one will already be too loud relative to the other drivers without padding. No upside at all to the second tweeter per cabinet. Do you have a plan to filter the signal to the woofer and midrange drivers...

    will these tweets and mids work together?

    The impedance mismatch is a problem, but that is the least of the problems with your plan. To use those 3 drivers, you will need a complex crossover circuit to divide the signal into the 3 bands appropriate for the 3 drivers. The "crossover" from your link merely is a high pass filter to protect...

    Finally finished my infinite baffle

    My friend's suddenly became like yours after working perfectly for a week. Solution: someone had turned "night mode" on in the receiver, which drops deep bass by about 20 dB with his yamaha.

    Looking for some subwoofer advice..

    I second the suggestion of looking for used bargains here or audiogon- higher class of sellers. Do not even consider making an Ebay purchase unless the seller has an extensive and nearly pristine feedback track record- you are in no position to deal with a bad transaction. If your parents are...

    Crossover questions

    Sending all deep bass to the sub is a good idea for many reasons. Your point about the receiver's amps is valid and thats just one. More important than that is that the woofers in the main/center/surrounds will make much cleaner 100-500 Hz sound when the cones are not wildly swinging at 40-50 Hz...

    Sub: powered or no?

    Having the amp built into the sub has the advantage of being cleaner, less kludgy if that matter to you.

    question about comcast hd -- what resolution?

    Ted, I live in Sac also and my comcast HD looks great on a PJ via component. Just gotta make that menu seting Jeff suggested to fire up 720p or 1080i (they both look good)

    "Overload"

    Try disconnecting each speaker *one at a time) and see if eliminating any particular speaker stops the overload.

    HDMI vs Component

    Make both connections to the HD receiver and compare them side by side. Pay particular attention to differences in delay to lock a new channel after changing stations( esp going in and out of HD sources)- either could be faster. Even a short delay can be annoying when surfing channels. If tbe PQ...

    4805 Shutdown ?

    This design blunder in the 4805 is the only thing I don't like about it. Mine is out of reach. I've plugged it through a power strip, but I rarely flip this switch. So the PJ doubles as an air cleaner.

    Setting Crossovers-- Help!

    Your room could be creating that. Move a sat into the middle of the room and measure with the mic as close as posible to the woofer. The dip may go away. Or take asurements from very different areas of the room, or try moving the sub and/or the sats.

    The suggestion of making the inner layer plywood instead of MDF is a great one whether you use t- nuts or screws. My problem with the t nuts is that the large holes from the inside must be PERFECTLY aligned or the screws from the driver side won't find the threaded chamber. This means that your...

    More Sonosub Questions

    I would not do this. With your very thick caps you would gain nothing over using beefy wood screws or deck screws into pilot holes. The benefit of t-nuts is if the driver will be removed and replaced many times- doupt you will need or want to do this. They are a huge pain in the ass to align and...
