Home Speaker Asylum

General speaker questions for audio and home theater.

Without a physics background, I have decided to try front firing subs next time.

I once compared a HSU Research HRSW10 down firing sub(see AA pic from Trader) and a Velodyne UL15 down firing sub. They were placed in the same spot which is on my carpeted wood floor, on the 2nd story of a wood framed house. The HSU sub bass was much more distinct than that of the Velodyne. This could be due to the different design of the two subs. I also thought that maybe the larger, 15 inch Velodyne driver blasting into the carpeted wood floor created more back pressure thus muddying up the sound a bit compared to the HSU 10 inch driver.

I still use the HSU stereo subs, but I want to eventually place them on concrete stepping stones to see if that will make the bass even clearer. I have done this at my second home out of state by placing stereo Polk RM1000 subs on 3 inch cement slabs from Lowe's(see second picture). These subs are also spiked and have heavy lead weights on the top. The bass from the Polk subs is very clear, and I attribute some of that to the cement platforms.

Anyway, my next installation attempt for better clarity would be to have forward facing subs with no near boundary influences like the floor. I might even place the Velodyne ULD15 on its side with its feet sticking straight out. Kind of like a big black bear sitting on its butt. Pretty ugly, but possibly clearer than a down firing arrangement. To be continued.
