    Re: Flex Your PCD Mettle:

    Purchases through JBL Pro Parts are at full-bore MSRP, but we're talking $6 apiece for these nice 6" square waveguides. Have the correct part numbers from the Tech Sheets on hand to minimize hassles. Dave and Carla at the other end of that phone number are friends of EconoWave and will do what is necessary to get you the parts you need. Tell them it's for that, as they are well familiar with our gig here. They get it, and have sold literally hundreds of waveguides direct to E-Wavers over the past several years.

    Your JBL Pro dealer or JBL Authorized Service Center may give you a bit of a discount if you ask, especially if you do other business with them. Asking for a discount on a $12 pair of waveguides is not gonna get you good service for just those, however, which is why I suggest going direct for that. As woofers go, these are fairly expensive at $80 apiece MSRP, but they're not your ordinary buyout fare, either, as you can see in the specs, so some nominal discount may be in order.

    Know that there will be some delay ordering through the dealer or service center; they'll be doing the same, ordering from JBL Pro Parts and having the items shipped to them instead of you. That means there's a service involved in doing this, a service that falls outside their typical course of business with JBL, and they deserve due compensation plus shipping for that, in my view:

    I designed one of the projects in this thread using HolmIMPulse, and then verified with CLIO. 10e, maybe, it was; the index is in the first post of the thread. Click "First" at the top or bottom of any page in this thread to get there....

    Re: Flex Your PCD Mettle:

    Thanks, is the pricing any different if ordering the WG's through a service center vs. direct?

    Also, I know you use CLIO but do you have any experience with HolmImpulse? I decided to try it out since it can export the necessary format for PCD as well as Hypex DSP amps. I spent a few hours this weekend and could not get a reliable/usable measurement of my two XD120 test boxes. It seems I am getting some sort of feedback that is throwing off the "auto detect gating". I have tried all the different detect modes and while some produce a different response, none of them look right.

    The waveguides you purchase direct through JBL Pro Parts:

    The woofers, they can't sell you direct, so you have to go through a JBL Pro dealer or authorized JBL service center for those. If you do that, you may as well order the waveguides through them, as well.

    Yes, when the B&C woofers get here, I'll run them 2-way, as well....

    Re: Flex Your PCD Mettle:

    Zilch, what is the best avenue to purchase the JBL waveguides and woofers? Don't want to burden them and end up with another QSC 152 scenario.

    Do you plan to test the B&C vs. the 226J in the standard 2-way version as well?

    Our better halves hear this stuff more than we do, but DE250 is smoother than the titanium D220Ti, yes....

    Re: Flex Your PCD Mettle:

    So I know this has brought up a million times before, the de250 and the 220ti paired with the 152i waveguide.


    Is there an audible difference between the two? They both seem to measure the same looking at the FR graphs but the De250 uses a Polyimide where the 220ti uses a metal diaphram(titanium). I have a selenium 1425 setup with my speakers and some of the highs can be absolutely brutal on the ears (laser shots in star wars the glass breaking at the end of order of the phoenix), it makes me wince a little bit and displeases the better half. The speakers we had before this were some dayton silk domes.


    So am I noticing something that is prevalent with metal CD's or just noticing new effects that the silkies couldn't represent?

    Closed-box cab resonance peak (Fc) is 80 Hz.

    You're gonna have to wait for the PCD files, but those will not show below 200 Hz. Ported, look at the factory spec for AC16....

    I have a woodworking pal with a complete shop who's helping me with the baffles. I give him blank baffles (spares are available for all of the Dayton cabs,) driver and waveguide, and a layout, and he comes back with milled baffles ready to load.

    As I demonstrated in the Mini E-Wave thread, mounting flush matters....

    OH, MAN! The big boys with custom drivers in their arsenal certainly know how to make this happen. I put Celestion CDX1-1731 on the little 6" square waveguide, dialed the L-pad flat within +/- 2.5 dB, and now can't wait to get this little guy into PCD and optimized....

    Zilch, what 8" driver are you using here with the JBL 6" WG and Celestion CD? And, did you rebate those drivers or have it done? Those look great. If they perform well, I'm in.
