Subwoofer without hi pass filter

Hi!

It's not absolutely necessary, but without it your man speakers and amps will still have to reproduce the bass, where most of the energy is. This will limit their dynamic range in terms of both excursion and amplifier power.

Using a high pass filter the satellites get worked a lot less, their woofers stay in a linear operating area more often and you can turn them up louder without distortion.

Best,

I would recommend caution. Very few people use a sub with your speakers. I'm not saying it can't be done, just that there's a high potential for mistakes. If I was in your position, I would contact John at Wellington Audio in FL. http://www.wellingtonaudio.com/

He's an expert on British audio products. I can't think of anyone more competent to help you. If you live in CA, maybe try Gene Rubin if he's within driving distance. Other than that, I would call John. I haven't been to his store in a few years, but last time I was there we just happened to be talking about subs for small British speakers like you have. He's one of the most honest people in the industry, and will not try and sell you something that's not in your best interest.

mb 1 audio02, Thanks for the info!

Yes.  

" Using a passive first order filter has two drawbacks: 1) you have to know the input impedance of your amp (maybe your amp meets the manufacturer's spec and maybe it doesn't) and 2) first order filters allow too much bass to reach the main speakers."

How do you come up with this stuff? As for 1), you have to consider the amp/speaker compatibility no matter what type of xover the speakers have. I've been in this business my entire life and never had a situation where someone had the slightest trouble picking an amp that will work with first order xover's. As for 2), I can easily prove you wrong. Not only that, I think you're just making the statement up altogether. (feel to counter that by providing the reputable source where you found it.). Vandersteen speakers use first order xovers. They have a reputation for making some of the best bass in all audio. They also have a reputation for merging seamlessly with subs for even better bass. If their way is wrong, why is the company so successful? The Model 2 is the best selling high end speaker of all time. Can you show me where you got that info, as well?

All that aside, what you're doing here isn't funny. There's a good chance someone will use the info presented in a thread like this to make a purchase. Obviously, you're upset with me and some of the others from yesterday's conversation. You were the one who lied and gave bad info. Now it looks like you're retaliating because you didn't like being proven wrong. If you have words for me, fine. But don't screw someone else up just because you're trying to get back at me.

OP

Just to clarify things, if you didn't read any of the other posts I was referring to, its the exact same topic topic (First order xovers) where he was proven wrong. He's just making these comments to get back at me and some of the owners. The guy has absolutely no idea what he's talking about. I don't mean to make a problem in your thread, but you need know what his motives are. He's not here to help you.
