I was considering changing the subs of my system and going to a high efficient route. I already have a Class D amp but the subs I have are too withdrawn listening to rock music and sucking up juice from an already strained alternator.
I was considering a high efficient pre loaded enclosure. Like a ported or bandpass 95-100+ sensitivity so I can use a low watt amp.
Every time I search around, I’ll find one that might work but then find that it’s discontinued and no one is selling it. I don’t want Bazooka though, their tubes are tuned too high, too thin and don’t seem to have any low extension.
Also, I might consider a slim sub or do an isobaric with them using an existing box but would prefer something matching and tuned from the factory but most aren’t very sensitive considering the low power requirements.
those “high output” bandpass systems tend to be tuned very narrow and are boomy “one note wonders.” They’re so underdamped that they’re annoying to listen to.
honestly if you want output and extension from something which will fit in a car, you need a speaker designed for a sealed enclosure (meaning heavy cone mass) and you need to throw power at it.
No ported has lower extension but of course it needs to be made correctly such as tuning freq. port size…etc. The entire quality of bass is all about the box design. BP boxes can also be accurate if made correctly but is much harder to design, besides it’s a sub, you don’t need a wider range that goes above 60-80hz anyway.
I already have sealed, it’s only benefit is flat freq curve and box size, along and a 1200 watt amp but as I mentioned, that’s what I"m trying to get away from.
I was just looking for suggestions on high sensitive pre loaded enclosures. Audiobahn has one that is 102 db but not sure what the tuning is and no one is selling it anymore
reflex enclosures can have lower extension but the size of the box tends to be a lot larger. for a given speaker, if you try to make a ported box the same size as a sealed you won’t get any more low-end extension and you’ll also have the danger of the port unloading (the port no longer helps control the speaker cone below its tuning frequency.)
there’s no free lunch with this stuff. either you get low-end extension at the cost of sensitivity, or you get higher sensitivity at the cost of low end extension.
besides, if you’re already throwing 1200 watts at what you have and you’re not happy, I don’t know what else to tell you.
still, if you tune a bandpass enclosure for high output, you’re generally going to end up with a high-Q system which will be a droning mess.
I’m aware but I was also specific in my question so I thought. I never mentioned I wanted a sub the size of a sealed. All I asked about was enclosures with the higher rated sensitivity so I can make the most out of low wattage. I never said anything about expecting 1200 watts worth of performance, I don’t want that much bass anymore, I just want low end to compliment the fronts and it’s compressed MP3’s so worrying about SQ obviously isn’t going to do any good. There are many home theater, passive radiator subs that are 116db /1 watt input…was looking for a similar equivalent of efficiency like they used to have back in the 90’s just so that my front’s don’t overwhelm the subs.
please link to a couple of these subwoofers. 116 dB/w/m is above even what the best (giant) folded-horn subwoofers can do.
I know, I’ve already told you. the only way the enclosure can give you more than the speaker’s inherent sensitivity is by putting it into an underdamped alignment (Qtc > 1.2) which means it’s going to tend to drone around the speaker’s in-box resonance. and doing so means you trade off low-frequency extension.
