Saturday I installed 3-Sd1 10" subs and 1 -SAZ 1500 amp in a 1998 Honda Civic 4dr. The subs were in a 3.40 cu.ft ported 3/4" mdf box that was braced accordingly. The ripple was -1.0 / fs was 25hz/fb was tunned to 34 HZ. Enough of the tech mumbo jumbo. I knew the system would sound accurate due to the ripple and natural QTS of the sub ,but I did not think it would be that L.O.U.D!!!!!!! These little ten inch 250 watt subs sounded impressive to say the least. The low freq extensions were accurate and flawless. They are taking the power well. The set up also did not fall flat on it's face in the upper subsonic freq ranges. They were a little sloppy at 60 hz plus but that could be cured with a smaller enclouser around 3.0 cu ft some low end freq extensions would be sacrificed but what the FU#$% more do you won't out of a sub that cost around $110.00!

The SD-1 are made in the USA not China, Korea, Yugoslovia ,or wherever. Welcome home HiFi now lets open a can of woop A$$ on some foreign garbage (MEMPHIS)(Crossfire)(and yes China Kicker). "Did I say that out loud and pi$$ off anyone. I'm sorry "Well not really!"

To give you an idea of how they sound it is like having the attack of 1989 Mtx Blue thunder 10" with the bandwidth of a early 90's JL Audio 10" and the volume of an early 90's Kicker Competition 12". (That is for the old school guys like me ,who compare everything to the glory days). For you newer guys, they sound like DD 2510's .They are not as loud ,but have that same tightness to them.

Good job Jacob. It takes something to make me spell check for this long, after 14 years in the bay. Long live Sundown ,or at least until I take a dirt nap.

Why not post up a review in the product review section also!!

I know a great place to get the SD-1's

The SD-1 is a sweet little woofer, I am very impressed so far and so is everyone that has installed them so far. They are fantastic for tight installs, the 10" model is only 5" deep! These also need very little power to sound great, I think that most people have totally lost sight of efficiency in recent years due to the availability of cheap and big amps

now now, no hating on my neighbors

sounds like a sweet setup

fyi, there is a factory pretty close, in hungary. they build some of the stuff ground-zero sells. but they mostly build cheap stuff.
