When the warmth of the day has cooled, arrange a therapeutic massage remedy at the spa adopted by a delicious meal within the restaurant. There you can take pleasure in a traditional Greek lunch amongst olive bushes and find out extra about the organic produce that supplies the hotel’s restaurant. You may even arrange with the lodge somewhat tour to its own organic farm, simply 20 minutes away from the property. However the GRS did bottom on the highest level sweep below the port tuning I ended up revising the highpass filter order from 12dB to 18dB/octave on that driver's DSP settings however the 12dB highpass is shown in these measurements.Spend your days at The Margi enjoying water sports activities, taking half in tennis on the close by membership, or teeing off in the local golf membership. Much of the limitation at the low frequencies (near tune) appeared to come from the inuke 3000 amplifier running out of steam rather then a limitation of the driver. However you can still get a good comparison between the two. I realized after I had swapped the driver over and been messing with it for a while that I should have taken the initial sweeps at a more standard output level. At the time I was just looking to see if the 18PT-8 would be suitable, what DSP setting it required and how it compared to the PA460. I started these tests on the PA460 at just an arbitrary level when I should have adjusted the output at the first sweep to something like 90dB. Measurements/SPL at 2m outdoors ground plane. Some wiggle room on those wattage numbers is fine.Ĭomparison of the Dayton PA460 and the GRS 18PT-8 VBSS designs.ĭIYSG 6cuft VBSS style cabinet used in 20hz configuration, single channel of inuke 3000 amplifier used. For two subs per channel it should be 4 ohm capable with roughly double those wattage specs into 4 Ohms and for 4 subs per channel it should be 2 ohm capable with roughly 4x those wattage numbers into 2 Ohms. The amplifiers used should be capable of 200-400w at 8 ohms for a single subwoofer per channel. Other amplifiers can be used if combined with a miniDSP or other similarly capable DSP to handle t he required settings that gives these subwoofers the correct bass extension and protects them from over excursion. This allows up to 16 drivers to be connected to one amplifier, 8 drivers per channel. The 6000 series can also be used however amplifier power is only maximized only when the drivers are used in sets of 2 placed in series then those sets connected to the amplifier in parallel. The 3000 series can power up to 8 standard VBSS cabinets, four per channel connected in parallel. The 1000 series placed in bridged mode can power one or two of the VBSS subwoofers cabinets. Behinger replaced the inuke line with the NX series amplifiers, these are nearly identical spec wise to the inuke series worked with minimal tweaking of the DSP settings. These amplifiers featured an onboard DSP which handled all of the DSP settings required to maximize the performance of the subwoofer. The VBSS was originally intended to be used in conjunction with the Behringer iNuke 1000DSP or 3000DSP amplifiers. Surprisingly the 18PT-8 has much lower distortion then the PA460 in the upper bass, so if you are looking specifically for the cleaner upper bass these designs provide over conventional subwoofers this may be the better driver for you. It does have some limitations such as less xmech which prevents use of the 15Hz tune and slightly less output and higher distortion in the low bass but at a fraction of the current price of the PA460 the GRS 18PT-8 is absolutely the current value champ. Indeed after testing the driver it performs almost as well as the PA460. With the price increases on the Dayton PA460 the newer 18" GRS 18PT-8 looked to take over the value throne. I have done thorough testing with the iNuke 3000 and the driver stays safe even when driven hard below tuning with the DSP settings limiting any bad noises from either the driver or the amp when being pushed hard into the limiter. It also has a very soft suspension and decent mechanical clearances so there is no trouble pushing it a bit at lower frequencies. While it is a bit limited in terms of coil overhang (xmax) compared to more conventional subwoofer drivers it is an 18" driver so it has plenty of surface area to move air with. The PA460 is very efficient in the mid bass leading to very little thermal compression and great dynamics in that range. True, but with the right balance of enclosure, power and proper EQ it does surprisingly well. An odd choice for a home theater subwoofer design you might say. This subwoofer was originally designed around the 18" Dayton Audio PA460 pro audio woofer.
