  • Who is selling 21" woofers besides Parts Express?

    I am in the market for some new subs. I would love to have two 21" subs. I am willing to give up some extension for a good amount of spl. Could the B&C driver or RCF driver over at PE get me down to at least 25hz in a sealed box?

    Are there any other companies online selling reliable 21" drivers?
    I came, I saw, I purchased.

    I found these:

    RCF 21

    http://www.brooklynbatteryworks.com/...s-3000-peak-4/

    B & C 21

    http://www.parts-express.com/pe/show...number=294-689

    Though I won't even bother mentioning the usual garbage from lowend producers such as Pyle Pro and GLI.

      Not a 21" but looks very promising.

        Thanks. I've heard about these sundown 18" drivers over in the diy section at avs. I was not sure if these were available for sale yet?

          Have you checked out the MTX Jackhammers?? The 24" will go down to 18hz and handle just over 33 amps each (4,000 watts)!! :woo:

            DD - if you are serious about the 21 inch builds, you should get some modelling software like WIN-ISD and "build" some models. We did that with two of the 21 inch drivers you are looking at, and made a business decision to stick with the 18's.

            I make business decisions regarding drivers based on what I would use in our theater.

                  I had Alex model a few 21's while I was discussing my sub purchase with them a few months ago. So I have a general idea of what type of performance I could expect for my budget. I am just looking at all angles right now before I make my next sub purchase. I just love big, powerful looking speakers and subs. So my choices right now are looking like two ported Caps, two of the new 18.2's, or two sealed 21" subs.

                    usspeaker.com has a multiple listings for 21's. But I don't know how reputable some of these manufacturers are.

                      DD - The top of the line Beyma is a solid 21 inch subwoofer. One could take it with 3000 watts, an LMS-5400 with 4000 watts or a pair of our 18 inch drivers with 2000 watts and get similar results.

                      This works with either sealed to sealed comparisons or vented to vented.

                      The difference being the LMS-5400 requires the smallest enclosure, the Beyma in the middle, and ours the largest.

                      Of course, an SS-18.2 will be $950 built for you while the other two will be $760 or $925 plus having the enclosure built.

                      Our cabinet maker WILL do single units, but it would not be inexpensive.

                      As an aside, I just paid for two new amplifiers for our "super sub" projects. One will be ideal for an LMS-5400 sealed.

                      It will deliver 5200 watts RMS and as a package with the LMS-5400 in a 4 cubic foot enclosure will be about $2299 plus shipping.

                        Which amp??

                        Btw Craig, have you ever heard an LMS?? Just curious on your thoughts on how it compares to your 18in. subs.

                          The amp is from a source that was introduced to me a few months ago, and at the time, they were changing their entire model line up. I will be keeping mum about the name of the source while we test both amps.

                          I have yet to hear an LMS-5400, but have an LMS-5400 and and LMS-15R driver at our OEM. The former will go into a sealed cabinet, the latter into a vented cabinet.

                          The LMS-15R, with this amp, will be about $1600 plus shipping, and should yield over 120 dB from 18 Hz and up, outdoors at one meter (which means over 114 dB at two meters, of course).

                            Thanks for the honest answer Craig. I've never heard of Beyma before but the specs on their flagship 21 look very good for the price.

                              Well this is my finalist. The Mach FTW 21.

                              I will wait for impressions on the first batch since they are running behind on their orders at this time. It will give me time to see what the potential problems are and how they are handled. But two 21's flanking my pro speakers for a 5.2 channel system is an awesome thought.
