So if I have followed this thread properly the Sub and Amp I was going to go out and buy to simply upgrade the sub is not possible with a 2018 B&O system?
Yes, you can upgrade just the sub with B&O. Use the sub signal coming out of the B&O amp to supply signal to your sub amp. To combat any eq roll off, utilize an amp from AudioControl that has Accubass built in. These amps are designed to eliminate this roll off. There is absolutely no reason to use the ZEN if you only want to install an amp and sub upgrade. DO NOT try to run an aftermarket amp and run your existing sub simultaneously. DO NOT utilize the stock B&O enclosure.
So my plan was to upgrade the amp and put a new sub in the existing enclosure. You say "DO NOT" use the enclosure. Why can't the enclosure be used?
First off I have used ForScan to set my B&O sub to aftermarket and I do seem to avoid the roll off before that. It basically has more volume.
With that said are all sub base signals being passed less than 120-250-150hz to it? If you know.
Now I know what your mentioning passed high level signals to that amp you mention. Some will say it’s not the cleanest way to do things, but I also know this and I also know for sub bass this can work well, especially if you have a dsp or amp that can work and convert to low level. But based on my question above could you not uses any amp that can deal with high level signals? Or does this signal still going to lack spectrum etc, coming from the B&O?
I totally understand the Zen route for a full clean rework. I’m just finding this alternate sub method interesting if that’s someone’s only upgrade. I’m between the two at the moment, but may not want to limit further upgrades.
Because the existing enclosure is only designed the oem sub. By putting a new sub in an enclosure that it’s not designed for, you aren’t improving anything.
Meh. it’s an inexpensive / immediate option for the budget minded. I guess depending on needs, but it’s either cram an 8” into the stock enclosure - meaning a heat gun, maybe some wrap and a new sub or go full on MTI behind the seat enclosure or under the seat if you don’t mind losing storage area.
I assume there aren’t any significant other differences from the previous Sony system, so yeah only adding an amp and sub still helps, but it’s not audiophile type improvements. I’ve done the cheap kicker sub and kenwood amp and it was a huge improvement over the sony. And the MTI 10” was an order of magnitude better than that so it depends on the short and long term goals. As this is/was the ‘under $500’ thread, I disagree that the stock enclosure, shallow 8” with an amp won’t be an improvement.
Utilizing the stock enclosure, in my opinion, is just lazy.
