I need some recommendations for enclosure plans, drivers and most importantly the amplifier modules.Id like to spend no more than $4000.00.
Feel free to chime in if you think I‘m making the wrong move, I just want to consolidate space and have a less intrusive looking audio system.

blach has fixed his KEF speakers in Austria, ping him, he wants to sell.
Pair of speakers with diy amp should be within your budget.

For a quick and easy way of gauging the max SPL’s you want to listen at, simply crank up your current system to the loudest level you listen at. Then measure the peak SPL’s at 1m from one of the speakers. Right between the mid and tweeter. If you don’t have a measurement mic, or SPL meter, apps are available for iPhones. But if you’re gonna go down this road you’ll want a measurement mic at least this good:

An active loudspeaker has multiple amplifiers, one per speaker, with XOs before the amplifiers. ie multi-applied.
A Powered speaker has one or more amplifiers inside the box… not an ideal place for them, but convienent.

The most ideal place for an amplifier is as close to the driver as possible. If vibrations cause problems with the system, it’s not engineered to modern standards.
Yes I agree that a sub-enclosure is ideal. However electronics can be made nowadays to be far less prone to distortions while being used in environments of high vibration. And when this is realized, far better sound at less cost is possible with active speakers. In comparison with traditional box and cable systems.
75db is my average listening level, perhaps as high as 105-110 when I’m in the mood. I’d like the bass extension in the 50-100Hz range, as low as possible given my budget.
I assume you are looking for a fullrange based speaker since you posted in this forum? If so, I can highly recommend the 10F/RS225 FAST/WAW speaker that I designed. It can be implmented with an active XO or a passive XO (provided in thread). You have a compact sealed standmount or a floorstanding TL that reaches down to 30Hz. It sounds great and you can see the testimonials of many who have built it. You could put a small Class D amp inside one and it would work fine. The newer Class D amps with DSP built in can be used as an active 2-way with one stereo amo board.

Yes, if cost is no object for you. The Purifi is currently one of the lowest THD Class D amps out there. TPA3255 amps are also great sounding and a bit more economical. But even TPA3116 sounds fine if all you need is 30w or so.
Also Class AB amps modules based on TDA7293 are superb sounding if well implemented.

Thank you for that differentiation, that’s why I come around here. I’ll research that.
That‘s a pretty wide range to work with if trying to dial in the best system for your needs.
The Purifi modules interest me because of their efficiency. especially within a sealed enclosure.
I could go higher, perhaps as high as $6000.00. Given that I would be building it, that seems like a fair amount for the parts. I’d like something in the full range category, if not immediately adjacent.
I’m talking about the SPL range. Not the price. If you want to dial a system up to the best way for your needs and budget, you need to know the max SPL’s you want, and the low end extension you want.
