![]() ![]() None of the above have trigger inputs which is an issue. But it does have an XLR input, that's a plus. It similarly has a lot of features that I simply will never use. Even allowing for the strength of the Hypex name, it also seems overpriced for a Class D amp, albeit slightly less than the Keiga. The Hypex is one that I had considered previously. But thanks for the link it's not one that I had considered previously. The Keiga seems overpriced for a Class D amp and it has a lot of features that I simply will never use. It also (uniquely in this 3) has a complete case over the internals, a personal preference. It doesn't have an XLR input which may be an issue as the sub is 5 metres (cable length) from the rack. I've considered the Dayton, it's Class AB and fits the budget OK, even with freight being 50% of the cost of the amp itself. Plus at 145 litres there simply isn't room for a second. I use my sub as a true sub woofer, not as a substitute for stereo woofers and as a result, at it's operating frequencies, it's completely omnidirectional. Someone suggested a second sub, which is not something that I would consider. For me the bottom line is, I just need a power amp. My DIY power amp used to have a full preamp stage built in but I removed it some years ago. I have in mind that all of my bass and LFE control is carried out by the USP-1 or the UMC-200, so I have no need for fancy pants cross over and equalisation facilities. If it proved to have more than enough grunt then getting an XPA-100, which is pretty close to an XPA-1L in Class AB grunt. ![]() So what I was thinking was trying the first XPA-1L in Class AB (500 watts into 4 ohms) as a subwoofer amp until the second XPA-1L arrived. To avoid the duty and GST issue I would get the XPA-1L's separately, with a few weeks in between. Left field, I'm seriously contemplating a pair of XPA-1L's for the FL&FR and then using the 2 freed up channels on the XPA-5 for Zone 2. Also not totally eliminated.Ī UPA-200 bi amped, (can I do that with a UPA-200?), possibly not enough grunt with 400 watts (maybe) into 4 ohms, similar to what I have currently. Not totally eliminated.Īn XPA-200 bi amped (can I do that with an XPA-200?), that would give me 480 watts (maybe) into 4 ohms, a little bit more than what I have currently. Not so much Class A waste though.Īn XPA-100 possibly not enough grunt with 400 watts into 4 ohms, similar to what I have currently. Plus all that Class A goodness would be wasted.Īn XPA-2 bi amped would also do, similarly 1KW into 4 ohms, but still a bit of a quality overkill, like feeding a donkey those same proverbial strawberries. ![]() The question is what Emotiva amps should I consider Īn XPR-1 would be seriously over kill, quality and quantity.Īn XPA-1 would do it, 1KW into 4 ohms, but a bit of a quality overkill, like feeding strawberries to pigs. So I figure it's time for a power amp quality upgrade, maybe not necessarily a grunt upgrade. This was OK when I had a 100 wpc (really ~80 wpc) AVR, but now I have a 200 wpc (really 200+ wpc) XPA-5. ![]() I chose 400 watts to align with my rule of thumb which says 4 to 5 times the sub woofer watts compared to the other 5. Which if I remember rightly I built around 1998, so it's 15 or maybe 16 years old. The current status is I have a single 17" subwoofer, 145 litre vented cabinet, tuned for 25hz, which is powered by a stand alone 400 watt into 4 ohms Class AB DIY amp. Need some help here guys, I need a subwoofer amp and my preference would be keeping with the Emotiva appearance. ![]()
