Despite not having a tweeter, I figured having a large, 8" driver would probably be ideal for open baffle, and was willing to settle for less than crystal highs. I was pretty committed to buying two of those and calling it a day, but then I took a look at amazon, and found a much wider selection of cheap full range drivers, many of which are coaxials.
The Lowther PM2C drivers were placed in an OB that sits on top of the pair of H frames. The baffle is made from a twenty inch square panel with the driver center located twelve inches from the bottom and 13 inches from the outside edge to generate unequal path lengths to each side of the baffle geometry.
19/out/2014 - Desktop open baffle speaker. You can get these drivers off of eBay and are said to sound good.
However, the OB speaker format, (like all speaker formats that have followed it), has its virtues and weaknesses. Our Speakers We offer music lovers simple, price competitive two and three way open baffle speakers designs incorporating the best in modern dynamic driver and crossover technologies.
Dec 06, 2010 · As Ive mentionnedin the past I have plans to use some car speakers I have in an open baffle configuration to find out if I like the 'open baffle sound'. The car speakers have ideal specs for open baffle use. It's a cheap way to experiment. +

Drivers for open baffle speakers
Up to 50 drivers can be placed on the baffle, and each of these is modelled by a set of point sources and their mirrors. The "speaker source density" spin box determines the number of point sources used per driver. Increasing this number is essentially a way of modelling the speaker directivity. Oct 9, 2014 - Full range Philips. Hi again.... well today I grabbed my "new" loudspeakers and I went to my friends in Elins Audio to test the small T amp Janusz have quickly build for me. It is not tube amp but digital one These drivers can often be used in an open baffle or bass reflex cabinet, but require higher amplifier power to drive them. There are very few true full range drivers that radiate from one source. The Diatones almost qualify, but are a bit weak in the bass, and a little weak in the highs. Trio15 Extended: two Eminence 15″ Open Baffle Bass Woofer and your favorite full range driver up to 15; Speakers size: 54cm wide, 131cm high Full Range Recommended Drivers : Tang Band (W8-1808) 8″ full range; Audio Nirvana Classic8, Super10, Super12 full range; Marc Audio Alpair10 and Alpair12; selected Lowther, Fostex and other drivers I started out convinced that If I was going to do this open baffle thing, I had to become a purist of sorts - one baffle with one widebander per side augmented by my trusty subwoofers below 100Hz. After all the JE Labs baffles made the Lowther PM2MKII, Audio Nirvanas or Stepen's Trusonics etc. all sound better than ever before.Monitor Audio Bronze FX speakers. Developing the perfect mix of reverberant or direct surround sound in a Bronze home cinema system, the wall-hugging New Bronze FX surround speaker will combine seamlessly with front channels to establish the immersive audio experience essential to successful home theatre design. The speaker is equipped with an external crossovers and volume control for the full range driver. The 5.0’s will work with high current tube- or solid state amplifiers, however the speakers were designed and voiced with our B-Series Passive- and Power Amplifier. If the fs is somewhere around 100Hz (which I suspect) , you just need a sealed cabinet that is large enough to not raise that resonance by any appreciable amount (acting like an infinite baffle enclosure). Likely these drivers have fairly high Qts because they were meant for mounting in an open space. the baffle width and driver Qts to manage the bass extension. Recently, I have added an open baffle theory section to my web site which documents some of the lessons I have learned. The first article in this section describes the trade-offs used to design a fairly compact open baffle speaker system using only passive crossovers. Shortly after theNov 25, 2020 · When you place a driver (e.g. SS 21W/8554) on a circular open baffle, then you measure a response that differs somewhat from the model under A. At low frequencies the response follows the 6 dB/oct slope, but the first peak and null are not clearly formed. Also, in the rear of the baffle, the response rolls off more than in front. Open Baffles. Open baffles are free from cabinet- resonances which downgrade the signal- quality. The size of image is bigger and more natural compared with monopole speakers and the open baffle shows best micro- detail in the midrange.

I am the original owner, purchased in 2014. Used in an open baffle application for about 4 years. They replaced 8" full range drivers (SK-98s) in my open baffle and I felt they bettered them the behavior of open baffle and dipole speaker designs based on conventional drivers which should be taken into consideration for any such design. Other factors also enter the picture which have not been discussed. hopefully these will be expanded upon in the future. For example, all the cases above assume that theThe result is the Deep Space One Mk II, a speaker that delivers a big, natural and realistic sound, from a compact, contemporary package. Thanks to our own typology, the Open Enclosure ™, we have managed to fold an open baffle speaker onto itself so to speak. This results is a speaker with the virtues of OB: resonance free bass and a really ... You will get a feel how OB (open baffle) speaker will sound. Spend 800 rupees buy 2 Philips full ranger driver (what we generally call speaker), buy two simple MDF plank of size 10" X 24" each, have one hole fit for mounting the driver at the top end of the plank. For an Open Baffle speaker using a passive crossover we actually require a driver with a high Qts. A Qts > 0.77 will mean that the amplifier will find it easier to drive the speaker as the frequency becomes closer to the system resonance. Just curious, will it work if one buys these drivers which are rated 150 to 200W and make open baffle speakers with horn tweeters and then rather concentrate on good quality components for the crossover parts? Want to try open baffle project but don't want to pay a arm and a leg for speakers. Apr 30, 2017 · From the Speakers thread. Here is a new system using a wild configuration....

These drivers are exceptional. I am running them on large open baffles (modeled after the Decware Zen Master speakers - which by the way; there is a LOT of information on these speakers on their forums). They *need* break in time - the sound has smoothed and settled quite a bit in the first 250 hours of use.
Dec 12, 2017 · Don't forget that the first open baffle speaker was the Dahlquist DQ-10. Woofer in a sealed box and 4 drivers (mid, upper-mid, treble, super-tweeter) mounted above in a horizontal array. A favorite of both Harry Pearson (TAS) and Peter Aczel (The Audio Critic). It resembled the Quad ESL (a favorite of John Dahlquist) and was about the same size.
The nature of an open baffle speaker is that as frequency decreases, the front and rear radiation from the speaker driver is more and more able to cancel. The result is a figure 8 pattern, with the "waist" of the 8 representing the driver on the baffle, and the round portions representing forward and rearward radiation.
The Q of a speaker system is its resonance magnification, so a low Q speaker exerts more control than a high Q speaker. As to why high Q driver is believed to be better, it depends on the situation. Case A: the resonance is out of the passband of the driver (it is lower than the driver's f3 on a given baffle size).

Aug 01, 2015 · The Loaded Baffle Acoustic Transducer. What is L.B.A.T.? The L.B.AT. is basically a loaded open baffle, similar to the loading of a horn driver but without the flair. The technical benefits of this design is: Bandpass filtering. Lower distortion. Increased power handling.The listening benefits of this design is: Realistic bass. Speed and accuracy.
I guess when open baffle is mentioned currently, I think of the Emerald Physics - a baffle with the unboxed drivers hanging out the back. Basically a dynamic speaker without the cabinet. I had (well, still have sitting around) DQ 28’s, but they have boxed mid and low drivers. Time aligned drivers are a good thing.

Driver Selection: Full range open baffle speakers require a large woofer to move enough air to have acceptable bass. An Eminence Beta-12CX was chosen as the woofer due to its 97 dB sensitivity, 0.48 Qts, and 1” coaxial port. A Dayton D250P-8 polyimide compression driver was chosen for the tweeter after experiencing harshness with titanium ...
Not a lot of open baffle talk. I think that's how forums work the ones we frequent, well its our community. The people that hear horn loaded bass say it the best and the people that here OB bass say they will never go back. I find it hard to believe when people in the audio community don't know who Danny Richie and GR research. DIY and a Texan.
The full range driver goal should be ~87.5 dB/2.828 volt/m for this size baffle. This is 6.5 dB below the woofer’s value. Inserting an L-Pad circuit into the
I may try my hand at a very simple build of an open baffle ripole subwoofer. I read about various form factors then stumbled across a Bulgarian speaker and got the idea for a simple triangular shaped contruction with the two subwoofer drivers mounted facing each other.
This makes building an open baffle speaker much easier and less expensive than conventional speaker designs.I particularly like the open and boxless sound of the open baffle speaker. Since there is no enclosure containing the back wave of the drivers, the speaker radiates out the front and back. This also helps create a large soundstage.
It's also worth mentioning that the larger the baffle plate that open-baffle drivers are mounted on, the lower their bass response will go. At any frequency lower than the baffle plate diameter, the bass response of an open-baffle speaker rolls off at 6dB per octave and must be compensated for with equalization (placing great demands on both the amplifier and the bass driver).
In the case of open baffle speakers, there is a reduction in the bass output due to the cancellation of lower frequency sound waves emanating from both the front and rear of the driver. Exactly what sort of bass you can get out of an open baffle design will depend on the properties of your driver and the size of the baffle.

Supravox open baffle from the side. Supravox 215-2000EXC field-coil driver from behind. Very interestingly, the Altec/Supravox combination presents more and more robust bass (although not by much) and pointed directly at my listening chair, sounds a bit denser and weightier through the lower midrange.
This is a valuable consideration in any speaker build, but moreso with open baffles and small drivers like the ff85k, where it would be extremely easy to obstruct the path of the backwave. It's also important to provide at least some recess for the large woofer.

Infinite baffle. A variation on the 'open baffle' approach is to mount the loudspeaker driver in a very large sealed enclosure, providing minimal 'air spring' restoring force to the cone. This minimizes the change in the driver's resonant frequency caused by the enclosure.

Flat Baffle Type. A baffle is the only means to isolate the front sound from the back sounds. Drivers are mounted on baffles of a certain size. The larger the baffle, the more advantageous is reproduction of bass sound because the back sound must go a longer roundabout distance before it can get to the front of the enclosure.

Of the fullrange drivers I've heard, my bet is on the AER driver as being the smoothest and best sounding in a purist open baffle system (a decent horn around the driver would also help a lot). One of the most exciting sounding (very fast and vibrant) that I've heard is the field coil Lowther.
