I live near Parts Express headquarters. They have great stuff and have been a lifesaver during my many builds.

Big big fan! I refer everyone to you when they are like “wonder how much power my amp does😂” I say go to big d wiz !! You are the go to guy. Love your work. Thanks a lot man !!

I'd like to see more home amps reviewed and rated. Outlaw Audios, Emotiva, Parasound, Monoprice, etc.

[michijimc]

Been a PE customer for over a decade. Great company with a knowledgeable staff. When you began your listening test it certainly looked like you had a lot of air leaking around your driver which can really skew the measurements and listening tests. Great video as always, keep up the good work.

Just this one video I've seen two pieces of testing equipment I've never seen in 40+ years of electronics and just found out about your channel. Definitely a keeper

All these years and I finally get to see the guts and the watts. I have it with a 15" and I love it. Shakes the house really good. Thanks big D!! Yeah boy!!!

I've used these line of amps on a couple of builds I did for myself and friends. I really like them. I built a gaming system for my basement that gives my house " trunk farts " using this same amp. It powers two RF hx2's in a ported and dampened enclosure .

As most audiophiles would already know, that turn on/off thump will not be an issue when using a power conditioner or voltage regulator with a delayed turn on sequence. I run several high power amplifiers in my home setup but run a Furman power conditioner that has a variable turn on sequence which eliminates any chance of this happening.

I have the lowered power version with the Dayton 10" kit. It's been good for 5 years or so. I didn't have a ton of money, but have been pleased.

The bass in this video was so clean it turned my active subwoofer into a passive subwoofer.








No for real I never heard my subwoofer make such a clean and consistent bass sound xD

I have had a few of these home theater subwoofer amps opened up before, all had either a spdt switch that selects "on" or "auto", or a simple on/off switch on the power supply like this one has. The ones that don't have selectable "on" or "auto" ALL had a jumper somewhere on the board to select it. It's as simple as adding your own switch to the jumper. The reason for the "thump" here is that when you operate that switch you are cutting power to the power supply while the output stage is still active. When you turn it "off" at the amp board instead of the power supply it will mute the outputs before ot shuts down. It's just a cost cutting measure so they don't have to add an extra switch to the panel.

That parametric eq is tight as ..
It allows the boosting or cutting of freq
Room/setup tuning
Good stuff.

[fluxcapacitor]

ahaaaa i was just waiting for this amp review by you.BIG

[gregphillips.]

I made some Stereo Cabinets, fitted 2 "Blam" coaxial 5.25" speakers and 2 Dayton Audio 6" extra weighted passive Radiators and they sounded pretty good in the living area of a friends Hymer campervan.

Glad to see this test, it was satisfying to see it come in under the rating for four ohms, keep in mind it does outperform by a larger margin at 8 ohms. For my purposes the Crown Xli 2500 is a far better value, you can see the Xli 1500 beats the numbers by a lot. Based on the Xli 1500 tests, the 2500 should be able to roughly 982 watts at 4 ohms per channel, the biggest downside is it can't do 4 ohms bridged like the XLS 2502. Still though the Xli 2500 is the same price as this plate amp, and has lower THD... Many people say the fans are never noticeable, depends how hard you drive it of course, but we'll see because I purchased the Xli 2500.

I usually watch your vids on my phone thru the tiny speakers. Forgot I was listening to my BT and clicked on YouTube. Do It Bump Doe? took on a whole new meaning coming out of my M&K V-1250thx!! Guess I'll be listening on BT from now on. Great to see you mix it up with home, car, and weird audio.

[hztolife]

Try the square in or 12. They come in grey or black/white. Very good to replace any floor woofers. Bassy and loud. Available at Parts Express.

[BretonWiessner]

Always love to watch BigDWiz, he can really help me chose an amp

[bradlwykfulbright]

Been eyeballing those plate amps from Dayton for a very long time, never have been in my price range lol. One day I'll get one of the lower wattage, the 150 watt is all I need.
