Dear Mr. Rohn:

In response to the Staff's  February 16, 2006 letter to Mr.  Paritosh K. Choksi,
our  Executive  Vice  President,  Chief  Financial  Officer and Chief  Operating
Officer, and our follow-up  conversation that afternoon, I am pleased to provide
the  following  in  response  to  the  issues  raised.  With  reference  to  the
aforementioned  letter,  responses  will be  enumerated  by the same  number  as
indicated in the February 16 letter.

     1.   We concur with the Staff's  findings and have  revised the  respective
          filings to reflect references to years 2004 and 2005.

     2.   Copies  of the  Ernst & Young  letters  to  management  regarding  the
          material weaknesses are attached for your files.

     3.   ATEL  Capital  Equipment  Fund IX, LLC filed its 10-Q for the  quarter
          ended  September  30,  2005 and 10-K for the year ended  December  31,
          2005, simultaneously on December 21, 2006 with the details and effects
          of the  restatement of 2005 Quarters 1 and 2 included  within the 2005
          10-K filing. The Company's  management  determined that no significant
          adjustments  were  required  for fair  presentation  of the  financial
          statements filed with these reports, taken as a whole.

          Similarly,  ATEL Capital  Equipment Fund X, LLC  simultaneously  filed
          both its 10-Q for the quarter  ended  September  30, 2005 and its 10-K
          for the year ended  December  31, 2005,  on January 5, 2007,  with the
          details  and  effects  of the  restatement  of 2005  Quarters  1 and 2
          included  within  the  2005  10-K  filing.  The  Company's  management
          determined  that no  significant  adjustments  were  required for fair

          taken as a whole.

          ATEL Capital  Equipment Fund XI, LLC filed its 10-KSB on June 2, 2006.
          The Company's  management  determined that no significant  adjustments
          were required for fair presentation of the financial  statements filed
          with this report, taken as a whole.

     4.   We do not  currently  have an  anticipated  date for  filing the above
          referenced  Funds'  2006  Forms  10-Q,  but we  continue  to focus our
          efforts  to bring the  Funds'  statutory  filings  current  as soon as
          possible.

          We have not identified any additional material weaknesses during 2006.
          Corrective  actions  taken  to  correct  those  previously  identified
          material weaknesses include:

               o    As  regards  the  timely  identification  and  recording  of
                    impairment  of  leased  assets,   the  Managing  Member  has
                    strengthened  its  quarterly   impairment  analysis  through
                    additional management review of the analysis.
               o    As to initial direct costs ("IDC"),  the accounting guidance
                    has been  reviewed,  and a standard cost model (the "Model")
                    has been  developed  that  includes  quarterly  reviews from
                    management.  Information  from the model drives the rates to
                    be capitalized  on a lease by lease basis.  IDC is amortized
                    over the term of the lease  based on a  straight-line  basis
                    for operating  leases and on the effective  interest  method
                    for direct finance leases and notes receivable.
               o    Regarding the allocations of costs and expenses  incurred by
                    the  Managing  Member,   the  allocation  process  has  been
                    reviewed and revised, and systems instituted and enhanced to
                    assure that costs and expenses are being properly  allocated
                    in accordance with the Limited  Liability  Company Operating
                    Agreements.
               o    As to identifying and estimating  liabilities in the correct
                    periods, the Managing Member has performed a detailed review
                    to  identify  and  record  the  liabilities  in the  correct
                    period.  A  standardized  quarterly  review process has been
                    implemented  to  ensure  the  correct   identification   and
                    estimation  of  the  liabilities.
               o    Regarding the proper  accounting and related  disclosures of
                    the Company's  investment in warrants,  the Managing  Member
                    has reviewed the  accounting  guidance,  and a formal policy
                    has been  developed to ensure  compliance  with  established
                    standards.





               o    In  addition.  the Managing  Member has taken the  following
                    steps to  mitigate  the  weakness  regarding  its  financial
                    statement close process: a Chief Accounting Officer has been
                    hired and the  controller  position  has been split into two
                    separate  roles to ensure proper  management of the Managing
                    Member  and  the  managed   Funds'   respective   accounting
                    operations.  As reporting structures and protocols are being
                    evaluated,   an  additional   statutory  reporting  resource
                    requirement  has been  defined and a  recruitment  effort is
                    underway for additional accounting personnel.

     5.   We are  concurrently  filing an updated Exhibit 16 letter from Ernst &
          Young regarding the statements made in each of our revised Forms 8-K.

We further note that we acknowledge that:

     o    we are responsible for the adequacy and accuracy of the disclosures in
          the filings;
     o    staff  comments or changes to disclosure in response to staff comments
          in the filings  reviewed by the staff do not foreclose the  Commission
          from taking any action with respect to the filings; and
     o    that we may not assert staff  comments as a defense in any  proceeding
          initiated by the Commission or any person under the federal securities
          laws off the United States.

Should  you  have  any  further  questions  please  feel  free  to  contact  the
undersigned at our corporate offices in San Francisco.

Very truly yours,

Audit Committee and Management of

ATEL Financial Services, LLC as Managing Member of

ATEL Capital Equipment Fund XI, LLC


In planning and performing our audits of the financial statements of Atel
Capital Equipment Fund XI, LLC (the "Fund") for the year ended December 31,
2005, we considered its internal controls to determine our auditing procedures
for the purpose of expressing our opinion on the financial statements and not to
provide assurance on internal control.  However, we noted certain matters
involving internal control and its operation that we consider to be material
weaknesses (and significant deficiencies) under standards established by the
Public Company Accounting Oversight Board (United States).

A control deficiency exists when the design or operation of a control does not
allow management or employees, in the normal course of performing their assigned
functions, to prevent or detect misstatements on a timely basis. A significant
deficiency is a control deficiency, or combination of control deficiencies, that
adversely affects the company's ability to initiate, authorize, record, process,
or report external financial data reliably in accordance with generally accepted
accounting principles such that there is more than a remote likelihood that a
misstatement of the company's annual or interim financial statements that is
more than inconsequential will not be prevented or detected. A material weakness
is a significant deficiency, or combination of significant deficiencies, that
results in more than a remote likelihood that a material misstatement of the
annual or interim financial statements will not be prevented or detected.

Material Weaknesses

During our audit, we noted the following matters involving internal control over
financial reporting and its operation that we consider to be material weaknesses
as defined above.

The Fund does not maintain its own financial reporting process, and is thus
dependent on the Managing Member, Atel Financial Services, LLC, who is
responsible for maintaining the accounting records and providing the Fund with
financial statements in accordance with generally accepted accounting
principles.

The Managing Member's accounting and disclosure controls and procedures in the
areas listed below were determined to be ineffective.

1. The application of generally accepted accounting principles for leasing
transactions (specifically, timely identification and recording of impairment
in leased assets, accumulating and capitalizing costs for initiating leases, and
properly amortizing costs associated with the initiation of a lease).
2. Allocation of cost incurred by the Managing Member on behalf of the Company.
3. Process of identifying and estimating liabilities in the correct period.

significance of misstatements.

This report is intended solely for the information and use of the audit
committee, board of directors, management, and others within the organization

We would be pleased to discuss the above matters or to respond to any questions
at your convenience.
