Thank you for this video. These cleverly designed speakers are really great and easy for clever, handy people to repair. The Peavey 1801-4 cab with the black widow 4 Ohm Speaker is an absolutely perfect and brillant instrument cab. It is my favourite cab for bass guitar and because it's so rare, I take good care not to break it. I'm sorry to consider your upgrade as just eventual upgrade, because Peavey writes in its specs on black widow speakers back in 1993, that the 18" 4 Ohm version "matches better with the load reqirements of musical instrument use" than the 18" 8 Ohm version does. So if your purpose is not to use the cab with a musical instrument, it is probably an upgrade.
Before you remove the original basket, you have to clean first the center magnet using a vacuum cleaner to removed the small debris inside that causes damage of the VC.
The biggest problem with these cabinets are the wrong port frequency. To sort that out, get the FS of the new driver, and tune the port length to that frequency. The 1801 drivers has a FS of 43 hz. The tuning of the cabinet is 47 hz . This is because of getting most spl out of the 300w they can handle. Today we have much better drivers than this and hence a new tuning frequency is required.
Looks like you went out and bought a speaker without even checking the wiring on the original. You should have metered it when you got no sound and you would've seen that the wires had come loose. I definitely noticed you acknowledged the wires weren't hooked up when you pulled it out. Why not meter it there on the spot, check for cone rub and stick it back in. Why did you take it apart or even bother to replace it without at least testing it?
In the first video on these is where I discovered one was shot, so I put it back together, did not plug it back in the ordered new speakers. These seemed to work fine when I got them, ran them in she shop for hours. I guess one was on its last legs and failed...
The main advantage is to be able to to run more subwoofers to a channel in an amp and keep the ohms above 4 ohms and not make the amp run into 2 ohm load which the amp may not support. If you’re running an amp that can go bridge mode for 2400w max @ 4 ohms , then running a dual 18” subwoofer of Peavey’s such as the SP218 4 ohm version instead of the SP118 8ohm version should be able to run the configuration smoothly and not blow the woofers. If you do change the woofer from 4 ohm to an 8 ohm version, you will lose amplifier power per channel.
Simple but brilliant tip on using 1/4-20 studs as guides! Thanks for that!

I am a DJ, so sound reinforcement is my use for them..

Good idea...
Thanks
@@GlennsSpeedShopyou're welcome sir i have also Black Widow speakers inma youtube channel..☝️🤝 great idea.

Thanks for this. The tutorial may help with upgrading an old Peavey TNT 130 bass amp speaker. Looks like the back is sealed with tolex.
Great tip with the bolts. Use brass bolts and they wont be magnetic.
I have a black widow on my wall not the spider the subwoofer well a spider is a part of a subwoofer but a lot of people don’t get that.
Peavey OK OK 💯💯💯
Especially PD products
I have a pair of PEAVEY 1210T GREAT CONDITION IF YOU ARE INTERESTED AS i HEARD YOU LIKE TO BUY UP VINTAGE PEAVEY STUFF

Hi, I wanted to put a 4ohm woofer in a box that had a 8OHM woofer, do I need to rewire the box for the 4ohm?

Advantages from going from 4 to 8 ohm or???
Not smart, it’s gonna lose some power.

Me love speakers

Did I say PD I meant to say PV
If you ever get a chance you should try the cheapest 18 inch woofers you can find
I have a cheap single sub, can't recall if it's 18 or 15. Why do you suggest it?
@@GlennsSpeedShop late reply but just to mess around with and see what they can do
Well you know what I’m trying to say
