I just bought two Submersive's after not being in the market for subs for a while.


In look at offering from Mark Seaton, SVS, and JL to name a few, can someone explain to me the newer technology (amp, drivers, etc) that makes larger "older" subs like the Velodyne DD18 not as good as these subs with smaller speakers etc.


Thanks,

Ken

Much of it is in driver tech. The woofer in the DD18 probably has an xmax of 15-18mm at a certain distortion level. Seaton uses drivers that probably have 30-35mm with the same or lower distortion. Amps and enclosures haven't changed much.

Thanks for the reply, but I thought there were differences in amps with regards to now using digital class D amps.

While I certainly agree, I want to add that amps have come a long way. For instance, BASH/ICE amps are incredibly efficient and have really come a long way even compared to amps from several years ago.


For instance, Mark uses a custom-designed Icepower 1000w amp for the submersive.

Both drivers and amps have improved. You can get lower distortion and more excursion from drivers now, and you can get a lot more amplifier power for a lot less money.

The Velodyne DD18 can still probably sound as good as any other sub on the market and better than most until in reaches it's limits. When it does, it doesn't do anything dramatic. It simply stops getting louder. There are many newer subs, however, that for a lot less $$$ have much higher output capabilities mainly because of drivers that can displace much more air.
