How do you feel that tapped horns compare with more typical sealed subs (like Velodyne, Magico, JL Gotham, REL, etc, etc) and then compare again to front loaded horns? I am not asking about specific brands but more typology....Lastly I'm confounded by seeing the general presence of direct radiating subs being mixed with horn-loaded main speakers. Horn-loading subs matters, and they need not be utterly ginormous so long no lower than a 20-25Hz tune is required. My own setup is not horn-loaded between ~85 to ~600Hz - a range some may consider to be the most vital with horn-loading - but it will be realized eventually down the road. However the vertically mounted dual 15" woofers match the directivity pattern of the large MF/HF horn above them at the cross-over, and the subs are 20cf. per cab tapped horns....

I am contemplating the next move after the final fune tuning of the XLFs to our current electronics now that they have settled in reasonably well. I am thinking of taking a look at the Velodyne and going dual 18" in a single sub (Funk 18.2) or possibly 2 of those. Intriguing comments have been around their performance being considered by some as closest to front-loaded horn subs.
Thanks for any insights.
Mikael,First some observations and questions:
With your XLF main speakers in mind you'd want some serious displacement from the subs, and/or at least as important: distribution. Do you presently only use a single Velodyne, and how is it configured; with the XLF's running full-range and the Velodyne then overlapping slightly? Why do you use the Velodyne in the first place - what does it do sonically to your ears in conjunction with the mains, and what's your incentive of thinking about an upgrade here?
Implementation of any bass principle is very important, as is physics; the less those cones move for a given output, the less distortion and the cleaner and more effortless the reproduction of bass, so don't skimp on effective air radiation area here, nor, if you can/want to, efficiency. Naturally also the overall implementation and integration of the subs is vital, indeed some would claim that below the Schroeder frequency the implementation is more important than the specific bass principle used - be that sealed, ported, horn-loaded or other.
As an outset I'd always use a pair of subs, not only one, and some would say 3 or 4 subs for a distributed array (DBA) is the preferred scenario for smoothing out the acoustic response throughout the listening room, hereby avoiding severe peaks and nulls. Depending on how high those subs are low-passed different scenarios may be preferred; cross them high-ish above some 60-70Hz I'd go with a pair with each sub placed close to and symmetrically to their respective main speaker, and crossed below some 60 or even 50Hz a DBA may prove an intriguing proposition. Or, a pair as in the previous scenarios placed symmetrically and close to the mains could as well be the thing here.
Describing a difference in sonic characteristics between different bass principles can be tricky, because the implementation is so important and can be a varying factor to a degree that "overshadows" the importance of the specific bass principles used. That being said, and things somehow being relatively equal, horn sub variations are different animals compared to most direct radiating varieties. A horn sub, be that a FLH or TH, has the cone loading the air differently - i.e.: more gradually via an acoustic transformer, and hereby "cathing" or exciting the medium of air more effectively. This may serve to illuminate the sonic difference here, where horn subs tend to have a smoother and more enveloping feel of bass to them (like in: bass just "happens" in the room around you), where direct radiating sub varieties typically have a more "pulsating," ground-based and, to my ears, less layered presentation. Horn subs generally have a stronger mid bass "hit," and yet they're somehow less noticeable in the "mix." Horn bass very generally just is; direct radiating bass has a more produced or "with effort" feel to it. The latter can be quite animating to some, but it can also be too much - too noticeable with some genres of music. The sheer presence of bass as a physical experience can be quite overwhelming with horn subs at high outputs, more so than with DR subs.
With regard to FLH vs. TH, that's more difficult to describe. TH's may have a slightly fuller and warmer imprinting by comparison, and also "shake" the air a bit more effectively for a given size/volume. But other than that the real takeaway is that both FLH's and TH's are sonically different animals compared to DR subs, or at least that's my assessment.

Moreover I believe the best sounding, horn-based (hybrids or all-horns) setups are actively configured via a quality DSP solution. This offers a wide array of settings options into delay, filter steepness, notches, overall PEQ, etc. that passive filters simply cannot equal, not to mention the sonic effect (i.e.: sense of "bottleneck") a passive filter creates just by being in the signal path on the output side of the amp(s) prior to the drivers, with all that entails in terms of lack of driver control and the need for more powerful amps.
Lastly I'm confounded by seeing the general presence of direct radiating subs being mixed with horn-loaded main speakers. Horn-loading subs matters, and they need not be utterly ginormous so long no lower than a 20-25Hz tune is required.

Mikael,
Thank you very much. A few more details:
1. The XLF is run full range. The single Velodyne DD18+ is run from 40hz down (very steep 48db cut off above 40hz).
2. The Velodyne adds a sense of the venue and contributes towards the sense of foundation of the overall music presentation. What I like to call the sense that the instruments are nailed to the floor in the room.
3. When you play the system with the main amps off...you simply get a sense of energy in the air or a reasonably right pulsing/beat during certain passages. But having advanced the main rig over the last 18 months, I intuitively feel like this sub-40hz range might now be trailing in performance
In terms of more specifically, why the consideration for an upgrade:
- speaking with or reading about about audiophiles (and professionals like Dan D'Agostino) who have had significant experience running very large scale subs to create an effortless sense of venue. Dan D'Agostino for example at one point had 6 of his Krell Master Reference Subs (12 x 15" cones) with his Wilson X1 Grand SLAMMS. Arnie and his Arrakis and REL 6-pack (dual sub towers). The list goes on.
- And again, I do wonder what happens if we simply get more air displacement, lower distortion, more ease...what that does to the overall presentation
- I would have thought 'more' of what we get from adding 1 Velodyne.
In regards to your more technical questions around setup:
- Room/space remain an issue. While the room is 40' x 18' x 11'...it is a living room, and therefore having a sub-array is not in the cards. There is certainly a very good corner for a dual-18" sub or a linear stack of med-sized cones. I am intrigued by FLH but they are BIG for anything below 40hz down full range and wonder whether it could fit in that corner
- There could potentially be a 2nd location, but things start to get visually in the way just that bit more.
- It might be that it is better to wait for a different room configuration than to try to 'max out' the corner with a dual-18" sub (Funk 18.2).
Nevertheless, I am intrigued as having enjoy the advances in the main music listening range over the last 18 months, it would be nice to see that sub-40hz range match that.
Passive filters do not absorb that much power! Classic Audio Loudspeakers makes a reproduction of the Heartsfield loudspeaker (improved over the original) and gets 105dB 1 Watt/1 meter out of it.
With regards to bass, standing waves are a common problem in any room with parallel walls, particularly below 80Hz. In such rooms the bass cannot be fixed with DSP of any sort due to the fact that standing waves cause cancellation (and often annoyingly at the listening position), which means you can dump considerable power into that cancellation and it will get cancelled. The solution at such frequencies is something called a Distributed Bass Array. This is practically done by the application of multiple subs placed asymmetrically in the room to break up standing waves. It would be interesting to hear this done using horns capable of 20Hz response but practically speaking this means direct radiation subs. As long as the subs are not producing output at 80Hz and above they will not attract attention to themselves so getting them to blend is very easy.
Yes-Power loss-wise low to moderately efficient speakers are the ones most susceptible to negative effects with passive filters.

I have heard big FLHs before in massive rooms and it was indeed sensational...but it was never in a situation where I had the opportunity to make any real comparisons. And they were again absolutely massive...the size of a small car each.
Judging by what I have read in the thread, "Visit to Audiophile Bill to Hear His Horn Project," I would be in no way surprised if Bill's horn speakers, once completed, ended up being one of the top horn speakers in the world today.
Very nice too. I was lucky enough to visit one of his "retirement concerts" at the Royal Albert Hall, down the road from where I was living. This frail old man being helped to the sole instrument on the huge stage with 5000 people watching and litening was an event I'll always remember. Mostly Chopin, but all played in the wonderful way that only he could do. Petergot some Rubinstein Mazurkas on right now.
