In a quest for real deep bass I recently bought an EBS aligned Shiva, being so far too clumsy and stupid to build one myself. Price was the equivalent of US $500. And very sexy it looks in its aluminium clad body, all 142 litres of it.
So I decided to try out out side by side against my current Velodyne F1200R, even though the Velo sustained some shipping damage when I moved back to Australia from the States.
So I plopped the Velo on top of the Shiva and let rip. I listened, and did measurments using the RTA in my Behringer Ultracurve, and also Smaartlive and True RTA.
I was expecting the Shiva, tuned to 18Hz, to be as deep as the Velodyne, but play louder and cleaner.
Well, it does play louder. I was testing at night so I couldn't really turn it up, but it went loud enough.
However, it did not go as deep as the Velodyne. The Shiva had a pronounced roll off under 30Hz and was around 7dB down on the Velodyne by 20Hz. This was when both subs were measured at 85dB on the RS meter.
I then tried to see the effect playing louder would have, but under the steady pink noise the Velodyne started shutting down at around 95dB. This may be due to the shipping damage as the amp has a few quirks.
Anyone have any thoughts on these results. I'm happy with the sound quality and loudness of the Shiva, but not with the lack of really deep bass. It seems to be well constructed, so is this normal? And would stuffing the port get me more extension.
I haven't tried EQ yet, but have the ability to do so.
