How Much Bass is Enough

I get what your trying to do. Its an easy try. I could even use the Dayton plate amp I have. Its mono out, but its only the bottom end. It would show me if the 10" coax is up to the task.

I'm not sure the crossover you have a close up of is correct. I will take pictures of mine later today.

I think any speaker that goes down to 30Hz is good enough. The question, in my opinion, is not about how much bass there is, but how fast it is. It should be extremely quick with impact—you should feel it in your stomach, starting and stopping effortlessly without sounding muddy or overwhelming.

If you can clearly follow the electric bass and low octaves of the Fender Rhodes together on funk or psychedelic tracks, and it makes you tap your feet, I’d say that’s good enough. A good example would be CTI releases.

That said, despite the technical facts, I’ve always enjoyed the bass of well-designed and well-built tube amps over solid-state, and vinyl over digital.

Scott of Found Music who made my amp would make me a more affordable PP that could run my woofer. I wonder if I can seperate my digital controls from the internal class D amp. Or do I have to purchase a stand alone active crossover.

Couple of others on this thread are true pros
just try what he says I’m sure you will learn something on how better they get
at a past show they was a room with a similar style speaker
Tiny little tube amp and big side panels
can’t say best if show but was a pretty good sound

I agree but you need to have enough acoustic energy at lower frequencies
Many drivers play low but at went energy level ?? You need to fill your room to sound full.

Exactly! Bass is all about the volume of air being moved. A large diaphragm surface is therefore always advantageous; it rarely feels overloaded (large driver excursion results in high distortion). An open baffle is an energy-guzzling system in the bass. You can either force a smaller bass driver with active bass equalization below its resonant frequency, or you can use sufficient surface area—for example, multiple 12" or larger drivers—to achieve fast, clean bass. The right drivers are not those with strong magnets or low QTS(, which have a sharp drop in level at their lower resonant frequency (fs)in open baffle. Anything below 0.7 is completely unsuitable for open baffles.
The baffle should be 1m e.g side wings, which means that the sound should have to travel 1m to reach the phase-shifted rear sound of the driver. Then it only reaches 25-30hz with full sound pressure, depending on the driver used.

This woofer is a pefect exsample for openbaffle

The 15" woofer runs up to ~ 250hz 12db xover, the 10" mid driver from 250- 2khz 24db xover, horn tweeter 2khz- 20khz 12db xover
Just ran it through the computer, based on the component size and driver parameters. No guarantee or measurement.

So nothing limiting the sub frequencies downwards, running full range.
