Apologies for the late reply JLM, thanks again for your thoughts. Of course, I totally forgot that the enclosure won't actually impact the crossover region. I've been doing a bit more reading on crossovers and realised that I was using a series resistor for attenuation without the necessary...

Hi there CA Audiophile, thanks for the feedback. My design is actually academic, for my engineering masters degree project, and I unfortunately haven't been able to build any kind of prototype without workshop access thanks to covid, so my design is purely theoretical, hence the reliance on...

Hi JLM, thanks for your reply. My crossover frequency is pretty low at 1kHz; chosen because my woofer (Beyma 8BR40/N) starts to roll off around that point. I am using a Peerless XT25BG60-04 tweeter since it can take over from 1kHz, as its resonant frequency is very low for a tweeter at 589Hz...

**Apologies for the double post but I realised I started this same thread in the non-DIY speaker forum, so if any moderators see this I would appreciate it if you could remove the original in the "SPEAKERS AND SUBWOOFERS > Speakers" forum I am designing a crossover using Vituix for a 2-way bass...

I am designing a crossover using Vituix for a 2-way bass reflex speaker design and am somewhat unsure on which woofer frequency response I should import and use when designing the crossover. I have the infinite baffle response provided by the manufacturer as well as a simulated response I made...

Thanks very much!

Hi, I have been researching the physics behind room acoustics as part of a university project to design a speaker, and I keep noticing that in both room mode simulations and waterfall graphs only the 20Hz - 200Hz range is considered, suggesting that the influence on SPL of room modes becomes...

Hi Dan, I see your point about how much scope there is to counteract the resonances in the room purely by design of passive speakers. My hope has been to design the cabinet and choose drivers such that any big peaks and troughs in frequency response of the room will be compensated; however, in...

Hi, I am a mechanical engineering student currently working on my Masters project to "design a loudspeaker for a specific listening environment" (my project brief). I plan to design a pair of bookshelf-style passive speakers to use with my amp and turntable set up in a room in my parents house...
