Product Details

Yung SD300-6 300W Class D Subwoofer Plate Amplifier Module with 6 dB at 30 Hz

Yung International's SD Series Class D subwoofer power amplifiers are equipped with the unique ability to operate continuously at full rated output—a performance attribute not shared by most home audio amp designs. The benefits of this remarkable reserve capacity include solid, punchy dynamic range and fewer "nuisance" shutdowns when operated at sustained high levels. 6 dB of bass boost (centered at 30 Hz) makes this amplifier perfect for sealed enclosures and even certain vented box alignments.

The amplifiers are also extremely compact, lightweight, and cool-running, allowing users to enjoy the advantages of compact system form factors and flexibility of placement. An internal peak limiting circuit prevents amplifier overload, and protection against internal and external faults is also provided. Input power requirements are user configurable to either 115 VAC or 230 VAC line voltage.

Room optimization and system integration are accomplished easily, thanks to the SD Series amps' inclusion of fully variable level, crossover frequency, and phase controls. Signal input is connected via dual RCA-type jacks, including the means to accept the output of an A/V receiver's LFE output, and dual RCA jacks are also provided to facilitate line level loop-through. When in standby mode, the amp's full active operation is engaged by signal presence of less than 1/2 watt.

Specifications: • Measured power output: 300 watts RMS into 4 ohms @ < 1.0% THD • Signal to noise ratio (at rated power): >90 dB • Input sensitivity (@ low level): 210 mV/50 Hz • Bass boost: 6 dB @ 30 Hz • Low pass adjustment: 40 Hz to 200 Hz • Phase adjustment: Continuously variable from 0º (normal) to 180º (reverse) • Power requirements: Switchable, 115/230 VAC, 50/60 Hz • Dimensions: 10" W x 7-3/8" H x 2-1/2" D; Cutout dimensions: 9-1/4" W x 6-5/8" H.

Yung SD300-6 300W Class D Subwoofer Plate Amplifier Module with 6 dB at 30 Hz
Yung SD300-6 300W Class D Subwoofer Plate Amplifier Module with 6 dB at 30 Hz is rated 4.6 out of 5 by 15.
Rated 5 out of 5 by from Worked as plannedI built a sealed dual opposed 12" sub to add to the home theater. The drivers are Infinity 1262w and both are driven by this amp at 4 ohms. I am very pleased with the results. This amp runs cool and has controls that allow for good system integration.

Rated 5 out of 5 by from replaces amp in a Sony SA-WX700 push pull sub.The Sony SA-WX700 original electronics are Sony's Power Supply, control panel and sub woofer filters feeding through a B&O Icepower 250A amp module driving two 10" bass drivers, 6 ohm each, in a sealed push pull configured enclosure. After the Sony amp died and because I like the sound of this box configuration, I choose the Yung SD300-6 for it's slightly greater wattage and the 6db@30Hz for this sealed enclosure. I was very concerned that the total impedance would be 3 ohms but, so close to the minimum 4 ohm spec and actual impedance is always seems to be a moving target, I took the chance. The plate of the Yung amp is a smaller dimension then the original plate so I cut the hole and mounted the Yung on to the original plate. This was the most difficult step because the original plate is pretty thick and the margin of error to cut the hole for the Yung is quite narrow for a non craftsman with a old saber saw but I was able to position and mount the Yung on the old plate maintaining an excellent air seal of the cabinet.The Yung has not experienced any problem driving this 3 ohm connection so far to satisfactory levels and beyond. The sealed Sony sub is clear and very nice. I am very happy with the Yung amp.

Rated 3 out of 5 by from Amp Performs well, P-E Customer Service Rocks!Bought one a bit more than a year ago. When I posted that it failed, but was out of warranty, Parts Express reached out to me and offered to replace the unit free of charge even though it was just past the warranty. I loved the performance of this amp, it replaced a dead plate amp on my Infinity sub. Hope the failure was a fluke, the new one is working fine so far.

Rated 5 out of 5 by from Boost works nicely in my smallish sealed enclosureI have been building subs for quite a few years now for both home and car setups. I used this amp to try to build a "best of both worlds" subwoofer, good for HT and Music duty. While I can't expect perfection in both realms, I feel I have found a very nice compromise for both. I am powering a 13.5" 4ohm car subwoofer rated at 350w rms with this amp in a smallish 1.6cu sealed enclosure. When I had my non-boosted 350w plate amp it only worked well for music (which is what I wanted at the time) and not so much for low movie effects (which is to be expected in that enclosure, I used to listen to music a lot more and am finding myself watching movies more now), so I bought this boosted amp to try to bring up the lows in movies and still sound great for music. I didn't feel like doing an enclosure rebuild at the moment, and just wanted a fast, smart solution.Well, I am pleased to say that it does what I had envisioned. Music still sounds punchy and lively as it did before, and on movies it really helped bring up the 25-35hz low frequency rumbling effects it was lacking before. I was concerned at first that it wouldn't have enough power or that I would hear a giant hump around 30hz, but because of the small enclosure size and being sealed, it actually smoothed out my response very nicely in my large open ended room. Large rooms tend to NOT have very much natural low freq room gain like smaller rooms do. My subwoofer now covers the lows like a ported sub would, while performing very accurately like a sealed design. (again, not "perfectly" but very very nicely) I used my 350w non-boosted plate amp to power two 4ohm buttkicker LFE mini's wired in series, so approx 87.5w going to each, which seems to be perfect for those as well, playing 50hz and lower only, and for movies only. Don't care for those on music, they are too distracting and annoying for music imho, I have another review on those as well for those interested.One other nice thing about this amp is the control layout, my old amp had the knobs low on the amp under the inputs, and when you're reaching around to the back to make adjustments it was annoying, not so with this amp, your most important control is right on top and makes for easy access of fine tuning even with your eyes shut. I haven't noticed any turn on thump either which is nice.For those of you not familiar with sub enclosure properties, I would NOT put this amp in a ported or passive radiator setup, you would over exaggerate the lows far too much. Ported designs are intended to have better lows in the first place, and boosting them tends to make things sound very unrealistic and terrible on music, plus your port velocity would get pretty fast quite easily (chuffing etc) Ported can play music just as well as sealed if done right, just not a boosted ported enclosure.The ONLY con I have, is that I feel the cutout dims listed are about 1/8" too big, so when you do your cutout make sure you go on the inside of your line a hair. It puts the mounting holes very very close to the edge of the cutout when you go to mount the amp. I had to predrill very small pilot holes first or else I would have blown out the edge of the cutout at the very end of the project and would have been a hair bit upset had that happened.Overall, I'm very pleased with this amp thus far in terms of performance and design.Have fun with your projects!

Yung SD300-6 300W Class D Subwoofer Plate Amplifier Module with 6 dB at 30 Hz

I have a MK sub woofer, model - MX200 with a blown plate amp I would like to go with a Yung amp which of them would you recommend ? Or is there something other than a Yung that would be a better fit? Thanks

Asked by: Drew56
I would recommend either the SD200 or SD300 for this subwoofer, with bass boost. The 300 will buy you a little more headroom.

really interested in this amp and it is switchable to 240 v for Australia but is the plug suitable for Australia?

Asked by: Lloyd48
Unfortunately the plug is a standard Edison type and will need to be adapted.

if I use the speaker level inputs can I stir power full range speakers off

I have a Sony 100 watt X 2 audio receiver. If I run those outputs to the speaker level inputs on this amp can I still power full range speakers after I run the outputs from the Sony to this amp for my sub? Hope my question is understandable....
Asked by: jared2006
Yes, you will just have to split the output at the receiver or input terminals on the subwoofer amplifier and run them to the other speakers.

Do I build a cavity or no cavity?

I have a different question relating to the cavity... Do I need one built to protect the circuit board when it sits inside the 12" sub box or will the components be okay exposed inside?
Asked by: ikedog77
These amps are air tight and designed to be used without a separate chamber in the subwoofer box.

Can I add a large choke in searies to increase the impedance to 4 ohms?

I have a Sony Dual 10" (6 ohm) Subwoofer.The drivers are in parallel for a load of 3 ohms.The question I have is, Can I add a choke in series, with a 1 ohm resistance to bring the total load to over 4 ohms on this digital amp?
Asked by: cheapskate
rewire the woofers to series and then adjust gain for the additional load, the amp will love it
