In this blog post I feature back loaded horn design No.2095 and compare two different woofers...the Beyma 15LX60V2 against the Supravox 380EXC field coil woofer.
Original Blog Post: josephcrowe.com/blogs/news/15...
Bass Cabinet No.2095 is currently only available as a custom make-to-order build and can be integrated into a turn-key project including the midrange and high frequency horn.

You keep knocking it out of the park. Now that you have tested this cabinet with a traditional magnet and a field coil bass driver, I can only hope the next test will include the 416-8B AlNiCo bass driver from Great Plains Audio or something similar.

Love your designs. Bet it sounds fantastic. Do you build speakers or test them or just design? I really like what you do with Wood. The horns you carve are beautiful. Keep up your fantastic work ! 🇺🇸👍🎶

looks great. wonder if group delay would be a better metric for that subjective disconnect due to path length

@JosephCrowesDIYSpeakerBuilding 4 ай бұрын

Perhaps. Group delay was better than an equivalent bass reflex when I was simulating the design. There’s quite a bit of group delay from a port. But I should look at this closer to confirm. Thanks.

I'm very curious how you're crossing them at 300hz in a system with a relatively small mid horn? Can you please explain more about your crossover, and the other drivers/mid/high in this system?

@JosephCrowesDIYSpeakerBuilding 2 ай бұрын

In this application it is more like 600Hz -6dB down point on the LPF. The horn is a 450Hz Fc. If I said 300Hz in the video that was my mistake because normally it is 300Hz on my larger horns. Thanks

Have you tested any of the Acoustic Elegance drivers? I wonder how they compare for IMD to these drivers

@JosephCrowesDIYSpeakerBuilding 4 ай бұрын

I only have the AE Dipole 15 in a previous video. It is about the same as the Beyma for IMD.

Very nice Troy! Is it feasible to design a more compact version of this BLH featuring a 15" woofer with a lower Vas, like the FaitalPRO 15HP1060 for example? The woofers currently used, while excellent, have 'old school' specs that necessitate larger enclosures. Ideally, a BLH that, when paired with an ES290 placed on top, positions the ES290 at ear height (95-100 cm) would be desirable

Interesting comparison! Fieldcoil: What is with the variation of the field-voltage?

@JosephCrowesDIYSpeakerBuilding 4 ай бұрын

Less than 10 mv rms.

What are the subjective, listening qualities of open baffles when compared to back-loaded horns in your humble opinion?

@JosephCrowesDIYSpeakerBuilding 4 ай бұрын

Open baffle is great for being able to hear the bass. It’s a more gentler type of bass that feels directed at you rather than an event that occurs in the room. The BLH sends a shockwave through the room that’s complete and full. Open baffle has a strong leading edge on transients but looses energy almost immediately after the initial impulse, where BLH continues to carry that dynamic slam as a shockwave that reverberates against multiple room boundaries. For example, the BLH tends to shake the structure of the home, activating noises throughout the house such as HVAC ducting. This is just an observation for me, where it seems there’s much more sound power being literally pumped into the room. If you place your hand at the horn mouth you can feel the air moving back and forth a few inches. This is equivalent to a 60cm x 60cm woofer moving that same amount.

@Sebastian-gc2hc 4 ай бұрын

Fascinating, thank you for your reply. Does the BLH introduce coloration to bass notes of instruments like piano when compared to open baffle?

@jenniferwhitewolf3784 4 ай бұрын

Let me chime in.. I have been living with larger BLH for about 20 years, tuned a bit lower than Josephs, with GPA/Altec 515-8LF drivers. Nothing else gives you the visceral connection to the bass like a BLH.. I have have large array of 15" and 16" woofers, as many as 6 per channel, and not perceived the immediacy and energy that just one 16" in the BLH will do. It is an amazing experience. I have found no added coloration compared to open baffled, that sound anemic and empty by comparison after the first edge hit.

What about the purity of low notes of instruments?

Maybe missed it... what voltage were you applying to the Supravox's field coil?

The Beyma looks VERY similiar to a JBL 2226 woofer. Is there any cooperation between these as a manufacturer/reseller?

Begs the question of whether an inexpensive 15” woofer would also perform well.

@cdgee6399 4 ай бұрын

Depends is the answer. I recently tested an inexpensive LaVoce 15" woofer that was very good!

@JosephCrowesDIYSpeakerBuilding 4 ай бұрын

There’s nothing intrinsically expensive about a low distortion woofer. It just needs to be designed and manufactured in a way that maintains a set of parameters. This could easily be lost through poor quality control, or poor design execution for example.
