I suspect a setup problem is what you are dealing with if the Captivaotrs were beat by a couple of bp2000tls. I've heard Gorilla83's definitive tech towers with the powered subs and the caps put the defininitve tech subs to shame. Gorilla83 has nice Def Tech towers and he also owns a pair of caps. I'm sure he'll attest. It'll be a shame if you sell of the caps to 'downgrade' because of a setup problem. Gorilla83 discovered that if he runs the definitive tech subs and the caps at the same time he has a severe phase issue, and so we ran them a/b to check and both sounded louder seperately than when they were playing together. Another friend of mine counsil has the flagship definiitive tech speakers and he just turns off the subs because his seaton submersives are much better than the 18" subs in his Def Tech towers. Head over the JTR cap thread and lets get you straighted out and fixed up rather than selling off the caps.

Does the outlaw seem to 'shake' the couch/body more than the sealed subs? Play the grid entry for Tron Legacy...good test for what I'm describing.

Hi all - I received an email today from Josh, and the results are done on the VS-18.1.

Josh tested the unit as both a passive subwoofer with a pro-audio amp and with our new SUB1 BASH amp.

1. The VS-18.1 is $700 as a passive unit
2. The VS-18.1 is $1095 with the SUB1
3. The VS-18.1 pair is $1745 with the SUB 1

A Sub1 used with a pair of VS-18.1's will yield 5 dB more SPL than the single - the Sub1 does not quite "double down" in the lower impedence.

We asked Josh to test the unit both as a passive subwoofer and an "active" subwoofer with the SUB1 because we wanted to give people an idea regarding both ways to incorporate a VS-18.1 (or duals/quads).

One question was "how much performance will I give up by going with the BASH amp over a pro amp"?

Here are the CEA-2010 numbers from Josh for both Passive and SUB1 driven units:

Frequency ....... Passive VS-18.1 ......... VS-18.1 & SUB1
16 Hz .................. 101.4 dB .................... 101.3 dB
20 Hz .................. 111.1 dB .................... 107.4 dB
25 Hz .................. 113.9 dB .................... 112 dB
31.5 Hz ............... 116.1 dB .................... 116 dB
40 Hz .................. 119.2 dB .................... 118.1 dB
50 Hz .................. 121.8 dB .................... 117.8 dB
63 Hz .................. 121.5 dB .................... 117.2 dB

Avg. 16-63 Hz ........ 115.1 dB ................... 112.8 dB

These numbers match up well with both Apollonio's test using the Dayton amp, and also with our results here.

A pro-amp does deliver more SPL.

A SUB-1 does quite well, and has the benefit of having no fan, is bullet proof and comes with a 5 year warranty.

I have limited the report to 16-63 Hz for now, because this is the "wheelhouse" for a subwoofer system.

The SUB-1 is much more limited in the 80-125 Hz range, in comparison to the pro amp.

When all the results are compiled, I think analysis will show that the concept of allowing both options (passive or with a SUB-1 amp) makes a lot of sense.

Right now, I am sure a lot of guys are heading to Data-Bass to look at some CEA numbers on other subwoofers!

As regards the CEA-2010 testing.
If you look at the output differences between using the Sub1 and the pro amp there is not a lot of difference between 16-40Hz. Only a dB or so except at 20 and 25Hz. The differences in that range are because that is where driver excursion is minimized near the port tuning (Especially at 20Hz.) so it can take more power than at other frequencies. The small differences at 16, 31.5 and 40Hz indicate that the VS18.1 driver can't make use of much more power at these frequencies. This points to the Sub1 being a good match for the VS18.1 with just the right amount of power to get everything out of the cabinet below 40Hz without running it into the danger zone. The only distress noises I could get from the VS18.1 with the Sub1 were when it was driven very hard below tuning. It should be a bulletproof combo in practice.

Now at 50Hz and above the driver excursion continues to drop which allows more and more input power to be applied during the bursts with the pro amp which is why you will see greatly increased output 50-125Hz versus with the Sub1 amp. However the danger here is that the amount of voltage applied at the top end bass frequencies during the CEA-2010 bursts would easily blow apart the driver if applied at too low of a frequency or fry the coil if applied for more than a few seconds so the application of a herculean sized pro amp to the VS18.1 is a dangerous proposition unless careful set-up of HPF and limiting circuits is employed. Long story short... The VS18.1 has a rather good sensitivity and really doesn't need anymore than a pro amp with 500-800w per cab to extract the best it has to give. Anymore might be getting into the danger zone.

The amplifier used for testing is a Powersoft K10 on a 240v 50a ac line, bridged. .

My first decision as a business owner will be to sell off the remaining inventory of Chase Home Theater and to close down the company.



Thank you all for an interesting 4 years.

But I think I speak for the majority when I say that no one wants another American ID company to close it's doors - especially when not absolutely necessary. Have another option in this small community is never a bad thing.

Oh please, this "closure" was voluntary and the reasons are specious at best. I guess all of those CHT customers with warranty issues will just have to figure out something on their own since the founder has decided to close his business and leave them in the lurch because of an election result?. If it wasn't so pathetic, it would be funny ...
