QSC PL-000446GP Replacement Waveguide Horn for HPR152i 2-Bolt

Econowave DIY speaker builders and fans rejoice! After nearly a year of intense negotiations, QSC has allowed Parts Express to become the exclusive distributor of the famed PL-000446GP horn found in the HPR152i and HPR152F 15" 2-way full-range powered speakers. The 90° x 60° waveguide is designed to be used with 1" bolt-on compression drivers such as the B&C DE200-8 or B&C DE250-8, and allows crossover points as low as 1,000 Hz due to how it loads the driver, resulting in amazing off-axis power response. Dimensions: 14" W x 10" H x 5.5" D. Includes gasket. Supply is limited so act fast!

Rated 5 out of 5 by from Broad smooth soundBought these just to try them out. I put an Altec 806 on & swept them, nice flat response from 2k to 10k. Very broad coverage & nice smooth sound.

Rated 5 out of 5 by from Fantastic constant directivity!I am really impressed with the constant directivity of this waveguide. I am using it at 5 kHz and above in a 3-way system mating to a BMS 4540 screw on with the Eminence adapter which provides a smooth transition from screw on to bolt on for this waveguide. See Zilch's CD measurements for this waveguide: http://techtalk.parts-express.com/showthread.php?215536-Flex-Your-PCD-Mettle&p=1625810#post1625810I am using a JBL 2380a 90x40 for mids (500 Hz to 5 kHz) and the QSC 90x50 blends perfectly. Whether sitting or standing or across a 3 person couch, the frequency response remain constant with no beaming hot spots or nulls. I have tried quite a few horns/waveguides on the top and this one is the most transparent and un-horn like I have heard to date. Could not be happier.

Rated 5 out of 5 by from Excellent Horn LensFor serious s audio pplications, these will image better than most anything else out there. You can use in-expensive Selenium drivers all the way to nice Radian drivers on this horn lens and create a great, well imaged sound. Even better news is that the price has dropped substantially! This ,used with a suitable 15" mid woofer and crossing over around 1200 hz, will make for a great sounding speakers. I have built a pair of 15" two ways and know this lens to be a favorite of mine.One thing I also include doing is to deaden the lens is to apply Hush Mat, or similar product, to the back sides to lessen the effects of "ring through".This is a great lens, when applied correctly offer superb imaging and functionality for a real nice 2 way system. Now that they have gotten much cheaper they sound even better!!DC Audio Labs

Rated 5 out of 5 by from Tweeter Nirvana for big horn freaksUpgraded my DE-10 to DE250-8 compression driver but kept the ME-10 horn, which sounded very nice. When I got a pair of these QSC's and curved them against the smaller ME-10, there was no comparison. This horn/DE250 combo is smooth as a mile of velvet has a 700 Hz. cutoff, so using it from 5K on up with a single cap is no problem at any volume level. It is a "mini me" of my amazing Klipsch K402 horns with the Klipsch K1133 drivers, perfectly matching the polar pattern of the midrange in a 3-way all horn setup with tapped horn sub. Micro details that rival electrostatics, but with horn dynamics.

Rated 5 out of 5 by from econowave deluxeI bought this horn to build Zilch's econowave deluxe together with DE250-8 compression driver (as I already had the woofers). Pricing is good and it's pretty smooth with the DE250-8. I've got ringing in one ear from when I had an ear infection many years ago and I'm very sensitive to sharp/strident tweeters. This combo does the job very well, very neutral relaxed sound. A friend is interested in doing something similar and I suggested the bolt on selenium D220TI with this horn/waveguide as it's a bit cheaper, fits his budget.Only issue I've had is the bolts on the DE250-8 are slightly too short to fit this horn. They will fit, but you may need to cut off a little plastic from the horn to get the bolts tightened up well. Not a problem with the horn per se (as the bolts are supplied with the CD), but you find it easier to just buy longer bolts than cutting the plastic if your using the B&C DE250. Other CDs may fit fine with their supplied bolts.RIP Zilch! Thanks for sharing your designs, they sound really nice.

What is it made of, is it plastic?

Asked by: buyer
I don't have this particular horn but judging by the weight and experience with QSC it is most likely plastic or a molded composite material. That being said these are not cheap generic plastic and should be quite durable.
