It took longer a few days longer than was told but I'm very happy bulit a box for 2 sdr 18s using a skar rp 1200.1 sounds great can't wait till the 1500.1 arrives
I used this woofer to replace a round vintage Kicker 15" Solobaric 4 ohm sub woofer. Solobarics have small sealed enclosures (1.5 c.f.). The Solobaric has nice Deep bass depending upon music playing but most of the time the bass is almost nonexistent due to lack of port and small enclosure. I believe it is rated at 750 watts RMS. I have never really been happy with any Sealed subwoofers especially for my vehicles. They seem to lack the punch that I can feel that adds to the music can and lack the efficiency that I desire. This speaker has some type of corrugation on the paper on back side probably adding to the stiffness of it. It also has a large amount of foam making the surface area much smaller (probably around 14" vs 18) but many subs do the same thing. Even upon full compression of the driver, the foam does not appear to be stressed or even close to its stretching capabilities. The magnet and assembly is not overly large or heavy nor can my Alpine 600 RMS @ 2 ohms really move this speaker very much with all the surround. However with the box combination it does very well and is much more efficient than my 15" sub. It is all that I need for an upgrade from stock.I don't need a competition system that has many have thousands of watts of power with 18 drivers and no room for storage thus depleting the reason for a truck. Also so much Bass just invites more rattles and noise thus defeating the purpose of high quality sound. I have a 2008 Chevy Avalanche and want some kind of balance of usability vs the best sound I can get. The original Bose System with hidden sub was pretty awful. I am happy with this speaker it added the finishing touch but I wouldn't mind adding about 200 more watts per channel to this sub. Its crazy how much power you really need in an average car audio system. My last vehicle had 4 amps and way too many wires and speakers. Also with too many amps come too much power consumption that can be tough on alternators ect. They now have Class D amps which they did not use back then and are much more efficient. I think this speaker will add the finishing touch on my excruciating installation job.(took 3 months)
I'm running 6 of these (along with 6 15s) in my 26,000 watt theater and I simply can not speak to how profound these drivers are! They simply gobble up the wattage and deliver bass that many have described as "insane"! These aren't just "good for the price", they're "good" full stop! With 6 of these assisting, I'm able to drive a 1200 square foot theater to over 100 decibel at 10Hz!
Before you say "100dB is nothing" find a 1200 square foot space, stand 14 feet away from your closest sub and measure a 10Hz signal! Yes, these are that good! I'm blown away!
Great sub so far impressed with how loud and low it gets. Box size is 5.4 cf in a trans am lol yes trans am amp is neo dB drive 1500.1
