Ohms cab conversion

#2
Yeah, but it's not worth it because you have to replace all four speakers. Fourn8 ohm speakers can be connected all in series to get a 32 ohm load, all in parallel to get a 2 ohm load, or as two parallel loads in series, as yours are, to get 8 ohms.

If you're looking to go to four ohms to get more power out of you amp. I can tell you it won't make much difference. When I bought my Eden D410XLT back in the '90s I got the 4 ohm version so my amp would put out the full 400 WRMS. A friend got the 8 ohm version, and same amp (WT-400) so did side-by-side comparison. Nothing noticeable even being stupid loud. But he could add another cabinet while I was at the limit. Two 8 ohm cabinets will give you the additional power AND use the power more efficiently by moving a lot more air.

Thanks all. I really love this cab. Got it over a week ago. I'll just change my amp.

My hunch is that you're concerned about how many watts your current amp is rated for at 8 ohms vs 4 ohms.

Honestly, all other aspects equal, you would barely notice any difference if you were to convert it. Perhaps someone like @agedhorse could tell us how many decibels we're talking about (if given more info regarding your current setup).

Tell us what kind of amp you currently have and we can give you more specific predictions as to the results of converting the cab, or even getting an amp rated for higher wattage at 8 ohms. (By "we" I mean people here who are smarter than I am.)

I love my amp too but I'd be willing to get rid of her than my cab.

Amp is rated 2 ohms. It's an Acoustic Focus2R. I was planning on getting two 4 ohms cab.

But when I saw a 4X12 available locally. I had to grab her. Also only had to do trades to acquire my cab.

So what is your concern that is leaning you toward changing amps? To be more specific, WHY are you concerned about ohms?

I used to own an AI Focus. It's definitely capable of driving an 8 ohm cab (and to a pretty loud volume). I think someone fed you misinformation. "Rated 2 ohms" means you can run it at 2, 4, or 8 ohms. 2 ohms is the minimum load, not the required load.

Oh, I didn't know that! So I'm all good then. That saves me money.

Isn't it a logarithmic scale? You need roughly 10x the amount of power in order to double your volume? So if you only increase your power by a factor of about 2, you are at most looking are getting marginal volume increase, maybe like 10%?

You are correct. Doubling power barely makes a noticeable change in volume. Adding a second cabinet, however, makes a very big difference. The subs in my PA aren't loud because they're getting fed with massive amplifiers (fairly middle-of the-road by modern standards of amplifier output), but because there's 6 massive drivers all working together.

If I'm not mistaken the delta pro 12a's are rated at 400 watts each @8 ohms which would mean a cab with four speakers you've got a potential max wattage of 1600 watts? And the Focus 2R is rated at 450 watts @8 ohms. Is this the situation - a 1600 watt cab driven by a 450 watt amp with both running at 8 ohms? Depending how it sounds you'd likely get max power from the amp with no problem of the speakers handling the load. How does it sound?

With the V2, it doesn't matter one bit if the cabinet is 2, 4 or 8 ohms since the output is transformer coupled to the speaker. If you set the tap to 8 ohms, the amp will produce the same rated power into 8 ohms as if the the cabinet was 4 ohms with the amp set to the 4 ohm tap.

There is zero benefit to changing the impedance of the cabinet.

I suggest that you learn how your amp works before changing things based on an incorrect understanding.

Oh, it sounds like a monster! Very loud and sounds amazing. I love it! The loudest and my favourite cab ever. I had an Eden Nemesis 410 @ 4 ohms. My V2 doesn't even compare.

My main concern was that I thought that my amp might be too powerful for the cab. And might not be compatible. Don't worry y'all. I'm good now. ☺️
