Harley benton solid bass 115t cabinet: question about crossover and speaker replacement suggestions

[Nachtglast]

Hi y'all, I'm new to the forum, this is my first post...
I have two questions about the Harley benton solid bass 115t cabinet:
1- Somebody here that owns the aforementioned cabinet has tried to completely bypass the crossover circuit and the tweeter, to find if the speaker alone would play more full range?
2- Any suggested 15" speaker replacement for this cabinet, in the 100 - 150 € price range, celestion, eminence, fane or la voce, not too vintage sounding nor too modern...?
Thanks in advance!

1. Switch tweeter off. There is no crossover: Woofer is full range, directly attached to input jack and tweeter parallel connected via high pass filter.
   
2. Probably waste of money. Considering the price of new HB cabinet (185€) it cannot be very well made (craftsmanship or materials), and result of speaker swap is not easily predictable. I would considering to replace the speaker only if it is damaged. Otherwise save some money (if needed) and purchase good new/used cab.

If the cabinet is functioning correctly, it is not worth the money to attempt to replace the speaker. I recommend that you use it until you can buy another cabinet that suits you better.

Ook! Thanks for the advices...
Finally watched inside the cab... What kind of filter is this? I can read C1... Can you guess the starting pass frequency? Thanks

 

[paskisti]

C1 means capacitor 1, and let me guess the another one is R1 like resistor 1.

This is high pass filter but component values determine the cutoff frequency.

 

[agedhorse]

First order high pass filter. Value of the cam (and how the resistor is used) defines the frequency.

Hi, all,
This is also my first post here.

Actually, I bought this cabinet recently, studied it, measured it, and realized that it is quite well made (18mm plywood, iron hardware instead of plastic, good Tolex, etc.). I thought it was worth investing some money and work to improve it, so I immediately modified it with very good results:
- I disconnected and removed the tweeter, which is little more than a toy and is useless;
- I replaced the tweeter and the tuning hole with two pieces of PVC pipe, 7.5 cm in diameter and 13 cm long, painted black, to tune the box to about 44 Hz and lower the air velocity at the tuning hole;
- I replaced the woofer with a LaVoce NBASS15-30 neodymium woofer;
- I replaced the chrome corner brackets with black ones, a purely aesthetic change, but I had the black brackets in my drawer left over from another project.

With these modifications, the speaker sounds amazing, can handle more power, has become lighter... and more attractive to look at. All this with 2 hours of work and less than €400.

You inspired me to do this. I found a HB cab on FB marketplace with a blown speaker for 50 Euro. Bought the LaVoce NBASS15-30 and some bass ports. Everything all in was sub 300 Euro. I'm using this as an extension cab for my Ampeg RB210 and it sounds great. The cab is light(ish) at 29lbs has great low response and pairs nicely with my the RB and its 2x10 speakers. I am experimenting with blocking the tweeter hole and using one port but other than that I'm really happy with the results. The OP is right this cab is pretty well made, it's speakers are sh!t but the cab itself is good.
