Just perhaps not the most suited to the box which is why i asked.
Beyma 15LX60 (Version 1) Recone Kit 8Ohm
The time I spent looking for cheaper speakers I could have used building them. Has anyone tried this or modelled it?
Don’t forget though driver specs are never absolute. The PD will rip your head of in one of these bins, but lower EBP drivers though not 15lx660 low as the PD will smooth the sound out and make it more listenable.
What about the MaxPro drivers from Nightfire they usually have similar specs to the PD’s you can probably find a useable 15″ there, thats what I’m aiming for when I finally build some ‘s, they seem to be close to the PD line, at least the 18″‘s do. Displacement Volume, Vd cm. Just curious, but you’re in the US too, where PD drivers beeyma very hard to come by, almost all the Speakerplan designs have a PD driver as their first choice, so what do you use instead?
When the horn is less than 5. Is it just me? This page was generated in 0. With short folded horns, or bandpass horns like the HD15 the effect is even more pronounced. Most of my short horn designs will work down to 50 Hz because I design them to be sealed boxes first that just have a bit of extra gain and kick from the horn in the 80 to Hz range. I had to ask myself this question. I have spent hours upon hours 15,x60 to find cheap woofers for the plans.
Whats the rule a true horn has to be at least a quarter of the lowest wavelength it’s trying to produce path length from driver to mouth I think.

Lucky you have long arms then That said, the rule of thump was below 0.
Thanks for your time Rastaman. The PD is considered to be a great driver in these and the LX60 looks better in a lot of areas. Voice Coil Resistance, Re 5. I am with the understanding that if you build these plans with the recommended speakers that are given that you will not only have great speakers, but you will have great speakers you will be proud to say “Yeah, I built these”.
beyka You want a driver with a low resonance a powerful motor system and good damping, the PD has all of these. Effective Surface Area, Sd m 2 0.

A short folded horn with horn length of around 85 cm and a mouth area of sq cm, so a horn with an 85 Hz cutoff quarter space will sound really hard with high EBP drivers in them. For the driver to be properly loaded by a horn means a beymz length of over 5. And if you look, i’m asking because of lack of availability rather than price – i’ve got no problem sticking my hand in my pocket deep though they are! Nah, i’m just being stupid really, i’d like to keep them all the same loading and i do love the PD’s.
Or is everyone trying to build speakers of their own, trying to do it cheaper rather than better? Drivers like the PD will work in a short folded horn because the cab is not really a horn.
Hey don’t take my word for it, it’s not like I’ve ever built them yet. Was just offering what info I have gleaned from this site beymq others. Mechanical Quality Factor, Qms 8. This is just my opinion and my soapbox time. Pulling stuff out the FAQ: Below the horn cutoff most of these short horns will still produce a useful output down to the cutoff point of the sealed box So it looks like there may be some middle ground, but the Beyman may not be in it.
Do I want cheap speakers which I 1l5x60 bought and have blown. The way I see it is by building my own cabs, I can spend my money on components Yeah, but its not strictly a horn is it, that’s why i’m curious, and the LX series are supposed to be good in BP boxes. Probably, but then there’s the whole, it’s not really a horn, it’s a horn bandpass cab. Or do you import PD drivers?
Below the horn cutoff most of these beyam horns will still produce a useful output down to the cutoff point of the sealed box.

Suck it and see when it’s close I suppose. If I have offended anyone, it was not my intention. It may even be with a bandpass horn whatever it actually is, the parameters required change, it’s got a nice low resonance, and an average BL and below average Qts.
Yeah, it 15l60 just a thought as i can get them cheap and PD are out of stock of PD’s and factory is off on hols until 23rd August Basically the horn just adds a bit of gain from around 80 to Hz, the cab will produce notes above and below these frequencies, just at a lower volume. Is there not someone out there that is building better speakers rather than cheaper speakers?
