![]() ![]() In the lab, frequency-response measurements of the Cerwin-Vega HT-S15 revealed an effective low-frequency limit of 44 Hz and response flat within +3.5 dB from that point up to 100 Hz the response deviation increased to ☖ dB in the range of 44 to 150 Hz, the sub’s rated upper limit. Cerwin-Vega backs the entire system (including electronics) with a five-year limited warranty. The HT-S15 has rounded edges and is finished in a handsome black wood-grain vinyl on the top and four sides. Speaker-level connections are handled via five-way binding posts, which accept stripped wire, pins, spade lugs, and single or dual banana plugs. The volume and crossover controls are of the click-stop variety, which makes it very easy to duplicate previous settings - just count the clicks. There is a volume-control knob, a calibrated crossover-control knob, a phase switch, an auto/on/off power switch (which when set to auto will activate the sub whenever an audio signal is present at its inputs), speaker-level inputs and outputs, line-level RCA-jack inputs and outputs, and a 5-foot power cord. Such high-pass filters are common in subwoofers and keep the speaker from self-destructing at very low frequencies with high output levels.Īll of the HT-S15’s connectors and controls are located in the top left corner of the rear panel, next to the amplifier’s heat sink and above one of two 3-7/8-inch-diameter ports. The HT-S15 also contains a “subsonic” filter, which is said to limit its output below 30 Hz at the rate of 18 dB per octave. The speaker is driven by an internal power amplifier rated to deliver 200 watts maximum, and it has an electronic low-pass crossover that is continuously variable from 50 to 150 Hz, with a nominal 18-dB-per-octave rolloff. The woofer fires from the bottom of the enclosure, which is elevated a couple of inches off the floor by four rubber-tipped feet. Cerwin-Vega’s HT-S15 powered subwoofer is from the school of maximal output.Ī relatively big sub that occupies 2-1/3 square feet of floor space, 4 cubic feet of volume, and weighs 48 pounds, the HT-S15 sports a 15-inch paper-cone driver with a rugged die-cast aluminum frame. Be worth checking out.When it comes to performance, there are basically two kinds of subwoofers: those that go way down with some sacrifice in output, and those that trade deep-bass extension for maximal output. So your HED CV-3000's might indeed sound good with the D3's. Makes me think the stack for a CV is another CV, even from a different line. The sound is really coherent and the LS-8's are making a real difference. Which may have given me the motivation to dig deep into the closet and pull out my Cerwin Vega LS-8 bookshelves. However today I'm a little down, missed out on a good speaker deal myself. The results with my Bostons, Phillips, and Polks were ok but nothing to write home about. Although I've been playing the D3's mostly solo I have also been experimenting with stacking them with my other speakers. I was extremely fortunate to get my D3's when I did because an extremely perceptive fellow AK'er was about to do the same. How interesting you would post this just now. 'Cept someone seems to be a hair quicker on the trigger here on getting the gooduns' lately." These might sound well stacked with them. I've got some great HED CV-3000s I love (HED is a division of CV- H.igh E.fficiency D.esign). They look good with the grills off but I actually like them with grills on more, the brown material and CV logo look good to me. This is the second time I've owned these speakers and I really like them. I'd be interested to know the sensitivity rating (93-95 db?) and the crossover points if anyone else knows them. They play loud of course but they sound quite good at low and moderate levels too which constitutes most of my listening. To me the D3's are warm, rich and thoroughly involving. That's my opinion of course based on comparing them to my other speakers which are Boston A70 series2 and Polk Rti38. Plenty of bass, great mid range and very good highs which are detailed but not bright. Although Cerwins are supposed to be rock type speakers, I think this model is an excellent all rounder and sounds great on classical. You can see a picture in the member classifieds (sorry I don't know how to put it here, not too swift on photo management). I just picked up a pair from Kegger last weekend. They have a tweeter adjustment on the back of the speaker. They have a 10" woofer, 5" midrange, and (I think) a 1" horn loaded tweeter. The D3's are 27.5" high, 14" wide and 10.5" deep with about 2" of the height consisting of a riser built on the base of the speaker. ![]()
