I recently reacquired my actual first bass cab that I used heavily in the late 80’s and early 90’s. It’s a Peavey 1516. I have a ton of great memories with this cab so I plan on keeping it.
I have discovered that one of the eights is blown, so I plan on replacing both. However, as I like the size and form factor of the cab - 4 ohms, one 15, two 8’s wired in parallel - I figured I may as well replace the 15 at the same time to try and upgrade it into something more useable.
I have a few other cabs so I don’t need to do this.
It’s simply for fun and learning. So please don’t try and talk me out of it!
External Cab size: 29.5 x 21.5 x 16”
Plywood: 0.75”
Weight = HEAVY so hopefully I can drop a few pounds with newer drivers too
15 compartment
- Internal volume: 3.41 cu ft (taking into account bracing and driver displacement)
- “Ports” = two triangular holes at the bottom of the baffle: 4.25x4.25x5.75 x 0.75 deep
- Tuning: 67Hz
- Driver: Peavey Black Widow 1502-4
I am considering two other drivers. Both of which require creating real ports to lower cabinet tuning to 45 Hz
Here’s how they model in winISD:
- Black Widow – Yellow line with existing “ports”
- Kappalite 3015LF-4 – Green line with 2 circular ports 3.5” x 4.75”
- Delta 3015LF-4 – Grey line with 2 circular ports 3.5” x 4.75”
What do you think? Which one would you choose?
I am leaning Kapplite as I have experience with the 8ohm version of both drivers and I like the clarity. Though I could be happy with the Delta too.
A quick question about the ports and port volume. As winISD is modeling Circular and I already have the start of 2 Tri-ports in the baffle that I plan on using/modifying – can I just calculate the same internal port volume and be OK?
8’s compartment
- Internal volume: 0.55 cu ft
- Sealed
- Drivers: Unknown. Research indicates 90 Watts 42Hz-5kHz
I am really only considering one potential driver here: Eminence Alpha 8
Here’s how it models out with the three 15's. Pink line below:
Do you think I will be OK with these 8s?
I did look at the Faital W8N8-150 but they're a little pricey especially when you need two.
Do you think they match up with Kappalite 3015LF-4 OK?
Any other suggestions?
The current crossover is set at 600Hz but I am thinking have one built at 800 Hz with an L-Pad on the 8’s.
Any help/advice is most appreciated.
Also here is a shot of the empty Cab that will be getting some mattress topper and casters shortly:
