What is the current U.S list price of a 14BSST sq. amplifier?

[James Tanner]

The newest SQ 14B is $7995 suggested list US.

Hello folks

I was wandering if someone can tell me if the 14B comes with the 3db gain adjustment switch like the 4B does ?

[Fido2]

I have a question about my 14B SST also please. Mine was built in very late 05. Mine does not have the 1V/2V sensitivity switch and it also does not have the line voltage status indicator light. It also has two(one on each input) selector switches for balanced or SE. The manual shows just one switch.?

Hi werd,

Yes the 14B SST SQ has a 1v/2v gain switch.

Hi,

The manual may differ a little (I think in this case wrong) but there has always been two BAL/SE switches on the 14B - one for each channel. There have been changes in the 14B as we moved along so there may be features on the current units which are not on the older units.

Thank you sir. I have already begun saving my pennies for the 28B's...man I love these amps! They really thump my 802D's...just splendid!

So James, what's better -- a 14B-SST2 or a pair of 7B-SST2? (And how much does the pair pf 7Bs cost vs the 14B?)

-- Ian.

Hi Ian,

There would be 2 advantages to a 7B over a 14B.

The 7B being Mono allows you to place the amplifier very close to each speaker - always a good idea-- and the 7B has twice the capacitance in the power supply section over the 14B.

Other than that they are identical.

A pair of 7B's is about 5% more expensive.

James,

Would you mind explaining the same for a 4Bsst in bridge mode vs 7bsst

The original sst series if possible

and then sst² if that changes things.


I am trying to work out the best use of the amps I have,

6 x7bsst
1 x14bsst
3 x4bsst

thank you.

[vegasdave]

I would like to know as well, please.

Then why manufacture the 14B?

Hi Dave,

Three major reasons really.

1. Some just prefer to have a Stereo Package.

2. We are talking about very small difference here in performance between a 14B and a pair of 7B's in most home setups.

3. In a lot of Pro installs Rack-Space is at a premium so a 14B takes up much less rack space than a pair of 7B's.

Hi Mr.H

The main issue when you 'bridge' an amplifier is that is 'see's' 1/2 the impedance it does when in Stereo. So a 4B bridged into 4ohms would actually 'see' 2ohms.  Thus is a much harder load on the amp because the lower the impedance the more current it has to deliver.

So if your speaker is 8 ohms then a bridged 4B would work just dandy but if the speaker is 4ohms I would recommend the 7B as it is designed to operate down into that lower range of impedances without issue.

I see. So, it's a matter of convenience and versatility.

Hi Dave,

Correct -actually you said it better than me ... but I have trouble spelling both 'conveneince' and 'versatality'.

Hi James

Comparing a 7B to a 4B. Does the the 4B in mono use all 8 of its output transistors compared to the 7B that uses one less at seven? Would this be an advantage somehow over a 7B?

[James Tanner]

Hi werd,

Not sure I understand the one less output transistor question

james

[werd]

Hi werd,

Not sure I understand the one less output transistor question

james

Hi James

I maybe wrong but the 7b uses 7 output transistors right? and the 4B uses 4 output transistor per side right? If you run the 4b in mono are we not using both sides for 8 transistors ?

I could be totally wrong about that with the amount of transistors in output stage of either of those amps.

[James Tanner]

OK I get it now - the 4B uses 8 output devices per side in stereo and 16 total in mono.  The 7B uses 16 as it is mono already.
